Compounded Skincare for Healthy Aging: A Pharmacist’s Guide to Evidence-Informed Skincare

By Andrea Daniels, Pharmacist, Strive Pharmacy

Skin aging is not driven by a single factor. It’s the result of multiple processes happening at the same time—structural changes in the skin, environmental exposure, hormones, inflammation, and cellular activity over time.¹

As a pharmacist, I find it helpful to start with the skin itself. Before getting into ingredients or formulations, it helps to understand the foundation we’re working with and what may be influencing it.

That context can support more thoughtful conversations around personalized skincare and compounded formulations for skin aging.

Not every patient’s skin is dealing with the same drivers.

Some patients may be seeing more changes related to environmental exposure and photoaging. Others may be experiencing shifts in collagen production, hydration, hormones, or barrier function. And often, it’s a combination of several factors.

When we can better identify what’s contributing, it becomes easier to think intentionally about formulation choices and overall skincare approaches.

And that’s where the skin matrix comes in.

Why Skin Aging Starts With the Extracellular Matrix

Skin is more than a surface.

The skin has a living architecture called the extracellular matrix, or ECM. This matrix helps support the skin’s structure, hydration, elasticity, and resilience.1

Within the ECM, you will find:

• Collagen
• Elastin
• Glycosaminoglycans, often called GAGs
• Proteoglycans

These all play a role in how the skin feels, functions, and ages.

Collagen: The Structural Foundation of the Skin Matrix

Collagen provides structure and support within the skin.

It accounts for approximately 75–80% of the dermal matrix, making it one of the most important structural components of the skin.² The two main types of collagen in the skin are type I and type III collagen.³ Type I collagen is the most abundant, comprising approximately 80–90% of the collagen in the dermis and providing the skin with tensile strength and structural integrity. Type III collagen makes up most of the remaining dermal collagen and contributes to skin elasticity and overall dermal architecture.³

Collagen naturally declines beginning in early adulthood. A general estimate is about 1% per year4, though environmental factors, including UV exposure, can accelerate that decline.5

When collagen support changes, patients may notice that their skin feels different than it once did. This is one reason provider-guided care plans often focus on long-term skin support rather than one single ingredient or one single product.

Elastin and Skin Aging: Why Skin Loses Its “Snapback”

Elastin gives skin its flexibility.

It helps skin stretch and recoil. This is the “snapback” quality people often associate with resilient skin.

Elastin is produced primarily earlier in life, with limited regeneration in adulthood.6 That makes proactive care and long-term maintenance important parts of the skin longevity conversation.

GAGs and Proteoglycans: Supporting Hydration and Structure Within the Skin Matrix

Glycosaminoglycans, or GAGs, help maintain hydration within the skin.7

They support the moisture environment of the skin and help create the setting where collagen and other structural components can function. Proteoglycans are also part of this matrix and contribute to the way the ECM supports hydration and structure.8

When collagen decreases, elastin changes, and GAGs decline or lose hydration, the ECM changes too.9

That is often when patients begin to notice shifts in hydration, texture, volume, and overall skin resilience.

This is where compounded skincare for skin aging becomes interesting. The more we understand what is happening within the skin matrix, the more precisely we can approach formulation choices.

The Four Main Contributors to Skin Aging

When I think about the drivers of skin aging, I like to group them into four major categories:

1. Extrinsic aging
2. Intrinsic aging
3. Hormonal aging
4. Inflammatory aging

These categories help us think beyond the surface.

A patient’s skin may be influenced by one of these factors, or several at the same time. That is why personalized care matters.

Extrinsic Aging: UV Radiation, Photoaging, and Oxidative Stress

Extrinsic aging refers to outside factors that influence the skin.

One of the most important is UV radiation. UV radiation is a primary contributor to photoaging10, a process driven by cumulative sun exposure.

UV exposure can generate reactive oxygen species, which contribute to oxidative stress.¹⁰ These reactive oxygen species also promote the expression of matrix metalloproteinases (MMPs), particularly MMP-1, a family of enzymes that degrade components of the extracellular matrix, including type I collagen. This shifts the balance away from collagen maintenance and toward collagen degradation, contributing to the structural changes associated with photoaging.¹¹

Because type I collagen is the most abundant type of collagen in the skin, this matters when we are talking about skin structure and long-term support.3

Environmental factors may also affect barrier function and increase transepidermal water loss, which can influence hydration.12 Pollution and lifestyle factors may also contribute to the overall picture of extrinsic aging.

Compounded Skincare Considerations for Photoaging and Environmental Stress

For providers, extrinsic aging may lead to conversations around:

• Antioxidant support
• Barrier support
• Hydration support
• Skin maintenance
• Daily environmental exposure

Ingredients that may be considered in this area include vitamin C, polyphenols, sodium hyaluronate, and niacinamide, depending on the patient’s needs and the provider’s judgment.

Vitamin C is often discussed for antioxidant support and oxidative stress related to UV exposure.13 Polyphenols, including resveratrol and green tea compounds, may also be considered for antioxidant-focused care plans.14

The goal isn't to make skincare complicated. It's to understand what the skin needs.

Intrinsic Aging: Changes Beneath the Surface

Intrinsic aging refers to the natural, time-related changes that occur within the skin. Over time, several biological processes gradually become less efficient, including:

These may include:

• Decreased fibroblast activity15
• Reduced collagen production15
• Slower cell turnover16
• Accumulation of fragmented collagen15
• Reduced repair processes15
• Genetic and epigenetic changes16
• DNA-related changes16

Fibroblasts play a central role in maintaining the skin’s extracellular matrix by producing collagen, elastin, and other structural proteins.¹ As fibroblast activity declines, collagen production decreases while collagen breakdown continues, contributing to gradual changes in skin structure.

At the same time, epidermal cell turnover slows. As new skin cells are produced and shed less efficiently, patients may notice changes in skin texture, tone, radiance, and overall skin clarity.

These changes are part of normal aging and help explain why skincare goals often evolve over time.

Formulation Considerations for Healthy Aging Skin

When intrinsic aging is part of the picture, providers may consider ingredients related to:

• Epidermal turnover support
• Collagen-supportive pathways
• Peptide support
• Hydration
• Cellular energy support
• Long-term skin maintenance

Ingredient Spotlight

Tretinoin

Tretinoin is commonly discussed for its role in supporting epidermal turnover and collagen-supportive pathways. It is also frequently included in conversations surrounding fine lines, uneven skin tone, texture, and hyperpigmentation-related concerns.¹⁷

Because tretinoin may cause dryness or irritation, some providers recommend introducing therapy gradually, such as every two or three days, before increasing frequency as tolerated. Sunscreen counseling is also an important part of patient education because tretinoin may increase sun sensitivity.¹⁷˒¹⁸

GHK-Cu

GHK-Cu is a copper-binding peptide that functions as both a signal peptide and a carrier peptide. It has been studied for its role in cellular communication and pathways involved in skin maintenance and renewal.¹⁹

NAD⁺

NAD⁺ has become an area of growing interest because of its role in cellular energy production, mitochondrial metabolism, and DNA repair pathways.²⁰ Since every process involved in maintaining healthy skin requires cellular energy, NAD⁺ is increasingly being explored in discussions surrounding healthy skin aging and longevity.

Healthy aging is not a one-size-fits-all process.

Patients age differently based on genetics, environmental exposures, lifestyle factors, and their individual skin goals. For that reason, compounded skincare allows providers to personalize formulations by selecting ingredients that align with each patient’s unique needs.

Hormonal Aging: A Shift in Skin Biology

As hormone levels change with age, the skin changes as well. Estrogen receptors are found throughout the body, including within the skin and on fibroblasts—the cells responsible for producing collagen and maintaining the extracellular matrix.²¹˒²²

As estrogen levels decline, collagen synthesis and glycosaminoglycan (GAG) production may also decrease.²³ These changes can contribute to reduced skin hydration, elasticity, and overall skin quality over time.

Estrogen is not the only hormone involved. Changes in androgen and cortisol signaling may also influence inflammation and other age-related changes in the skin.¹

Ingredient Considerations for Hormone-Related Skin Changes

When hormonal changes contribute to skin concerns, providers may consider ingredients based on the patient’s goals and clinical history.

Estriol may be included in certain personalized skincare formulations because of its interaction with estrogen receptors in the skin.²³ Estriol is considered a weaker estrogen receptor agonist and has greater affinity for estrogen receptor beta, the predominant estrogen receptor subtype in the skin.²⁴ In topical skincare discussions, estriol is often associated with skin hydration, glycosaminoglycan (GAG) production, elasticity, and barrier function.²⁵

Because topical hormones have the potential for systemic absorption, even when used at low doses, patient selection is important. Providers should consider an individual’s medical history, and patients with a history of estrogen-sensitive conditions may require alternative approaches.²⁶

Finasteride may also be considered in selected patients experiencing androgen-related facial hair growth. By inhibiting 5-alpha reductase, finasteride may limit the conversion of testosterone to dihydrotestosterone (DHT), a pathway that has been investigated in women with unwanted facial hair growth.²⁷˒²⁸

As with all compounded skincare, ingredient selection should be individualized based on each patient’s clinical history, skin concerns, and treatment goals.

Inflammatory Aging: Chronic Low-Grade Inflammation and Barrier Support

Inflammatory aging, often referred to as inflammaging, describes chronic, low-grade inflammatory signaling that increases over time. In the skin, this persistent inflammatory state may contribute to cytokine-mediated collagen breakdown, extracellular matrix degradation, and impairment of barrier function.²⁹

Because the skin is not isolated from systemic physiology, inflammatory signaling occurring throughout the body may also influence cutaneous biology and appear in skin-related presentations.

When barrier function is compromised, the skin’s ability to retain moisture and tolerate external stressors may be reduced, making hydration and barrier support important considerations in overall skin care discussions.

Barrier Support and Inflammation-Focused Formulation Considerations

In the context of inflammatory aging and barrier function, providers may consider ingredients that support hydration, lipid balance, and cutaneous resilience, including:

• Sodium hyaluronate
• Niacinamide (vitamin B3)
• Polyphenols
• GHK-Cu

Sodium hyaluronate is commonly used for hydration support due to its ability to bind water and contribute to the skin’s extracellular environment. It is often included in formulations designed to support overall barrier function and hydration dynamics.³⁰

Niacinamide (vitamin B3) serves as a precursor to NAD and NADP and may support skin barrier function through its role in cellular metabolism and ceramide synthesis. Ceramides are key components of the stratum corneum that help maintain barrier integrity.³¹ In topical discussions, niacinamide is often associated with supporting skin tone, clarity, and visible redness-related concerns, as well as overall barrier function.³¹

GHK-Cu and polyphenols are frequently discussed in the context of skin maintenance and oxidative stress pathways, particularly in relation to signaling and environmental stress response.

From a formulation perspective, barrier support is often one of the most practical entry points in skincare discussions, as barrier integrity directly influences hydration, tolerability, and overall skin resilience.

Signature Ingredients in Compounded Skincare for Skin Aging

In compounded skincare for skin aging, ingredient selection should be guided by the individual patient’s needs, skin biology, and the provider’s clinical objectives.

The following are examples of commonly considered ingredient categories in formulations intended to support healthy aging skin:

These ingredients are not intended to function as a universal checklist or standardized protocol.

Rather, they represent a range of options that may be considered based on the patient’s presentation, goals, and formulation strategy.

This framework reflects the broader principle of compounded skincare: individualized ingredient selection based on skin biology and patient-specific considerations.

Why Topical Bases Matter in Compounded Skincare for Skin Aging

In compounded skincare, the topical base is more than a vehicle for active ingredients. It can influence spreadability, absorption characteristics, stability, cosmetic feel, and overall patient tolerability.

That matters because personalized skincare is not simply about selecting the right ingredient. It’s about selecting the right ingredient in the right formulation for the patient sitting in front of you.

When we developed Strive Skincare, we spent significant time in research, development, and testing. We evaluated how different active pharmaceutical ingredients perform in different topical bases because each base has unique formulation characteristics and intended uses.

Some of the bases commonly used in compounded skincare formulations include:

Medisca HRT Cream Base

Medisca HRT Cream Base is an oil-in-water emulsion designed to support ingredient delivery while maintaining a smooth, cosmetically elegant feel on the skin.

Providers may consider this type of base when looking for:

• Consistent spreadability and patient comfort
• A formulation that is easy to incorporate into a daily routine
• Compatibility with a broad range of active ingredients
• A balance between delivery and cosmetic feel

For many patients, formulation feel matters. A skincare routine is more likely to become part of everyday life when the product feels pleasant and easy to use.

Medisca PenDerm™ Cream Base

Medisca PenDerm™ Cream Base is designed for delivery-focused formulations and may support the incorporation of multiple active ingredients.

Providers may consider this type of base when a care plan calls for:

• More targeted formulation strategies
• Multiple active ingredients
• High carrying capacity
• Greater formulation flexibility

Because every patient's skin story is different, some care plans require a more individualized approach than a standard commercial product can provide.

Fagron Nourivan™ Antiox

Fagron Nourivan™ Antiox is an antioxidant-enriched cream base designed to support both ingredient delivery and skin-barrier considerations.

Providers may consider this type of base when thinking about:

• Barrier-supportive skincare approaches
• Hydration-focused formulations
• Environmental aging and photoaging concerns
• Skin exposed to oxidative stress

Why Base Selection Matters

Compounded skincare is not defined only by ingredient selection. It is also defined by the formulation itself—how the base supports the ingredient system and aligns with the patient’s skin, goals, lifestyle, and tolerability considerations.

A patient experiencing barrier-related concerns may benefit from a different formulation approach than a patient primarily focused on environmental aging. Similarly, a patient with sensitive or reactive skin may require a different base strategy than someone accustomed to regular use of active skincare ingredients.

This is why base selection is an important part of the personalization process. Providers are not only selecting active ingredients—they are also considering skin type, barrier status, environmental exposures, hormonal context, application area, patient preferences, and long-term routine adherence to support a formulation that is practical and sustainable for the individual.

While each of these factors may seem small on its own, together they meaningfully influence the overall patient experience with a regimen.

A More Individualized Approach to Skincare

Ultimately, skincare extends beyond ingredients and formulation design. It reflects the individual behind the skin.

Skin changes over time in response to environment, hormones, aging, and daily life. These changes are not uniform, and the factors contributing to them vary from patient to patient.

This is why individualized skincare is important. It allows providers to move beyond generalized recommendations and instead align formulation decisions with the specific needs of the patient.

Healthy skin aging is not driven by a single pathway, and it is rarely addressed with a single approach. Effective care begins with understanding both the biology of the skin and the context in which it exists.
