How to keep skin healthy, naturally, as you age

By Dr. Nathalie Beauchamp, DC

Have you, like me, started noticing subtle changes in your skin’s appearance? Perhaps you’re seeing fine lines, experiencing increased dryness, or noticing a gradual loss of firmness? You are not alone.

For women in their 40s and 50s, skin changes become particularly apparent as estrogen levels decline and cellular processes slow. While society often frames these changes as problems to be solved, I prefer taking a more empowering approach—one that recognizes that mature skin requires different care, not correction.

What’s happening on the surface is actually a reflection of deeper biological processes. Skin changes like these are signs of hormonal shifts, slower cellular turnover, and a gradual decrease in collagen and elastin production. Far from being flaws, they simply show that our skin’s needs are evolving.

As someone navigating this stage myself, I’ve found that understanding the science behind these changes helps me make decisions that are better suited to my skin’s needs. When we know what’s going on beneath the surface, it’s easier to choose strategies that genuinely support skin health, and boost confidence—no matter our age.

The biology of aging skin

Before exploring the best ways to care for aging skin, it’s important to understand the biological changes happening beneath the surface. These shifts influence the appearance, texture, and resilience of skin as we age.

• Collagen production decreases by about 1 per cent per year after age 20. Collagen is the protein responsible for the skin’s strength and firmness. As its production declines, the skin loses some of its structural support, which contributes to sagging and the formation of wrinkles.
• Elastin fibres become less functional and more rigid. Elastin helps skin return to its original shape after stretching or contracting. When elastin fibers stiffen and break down, skin loses elasticity, leading to crepiness and less bounce.
• Cell turnover slows from approximately 28 days to 40 or more. Healthy skin continually renews itself by shedding old surface cells and producing new ones underneath. As this process slows, dead skin can accumulate, making skin appear dull and uneven.
• Sebum production decreases, reducing natural moisturization. Sebum is the skin’s natural oil that maintains hydration and protects against dryness. Its decline causes skin to feel drier, sometimes itchy or flaky.
• Melanocyte function becomes less regulated. Melanocytes produce melanin, the pigment responsible for skin tone and protection from UV damage. Aging can cause uneven pigment production, leading to dark spots or patches.
• Dermal blood flow reduces by 40 to 60 per cent. Blood flow delivers oxygen and nutrients critical for skin vitality and repair. Reduced circulation can slow healing and affect the skin’s overall glowing appearance.

Collectively, these biological shifts illustrate why aging skin behaves and appears differently than it once did. Understanding these processes is key to adapting skincare practices that truly support skin’s health over time.

Science-based strategies for healthy, resilient skin at any age

If you’re wondering how to best support your skin through these natural changes, you’re not alone. The following seven strategies emphasize a holistic approach to skin care, taking into account diet, hormone balance, mindful habits, and making informed choices that help keep your skin healthy and resilient.

1. Collagen and copper peptides: structural support from within

The extracellular matrix (ECM) provides the structural framework for skin health. As we age, both the quantity and quality of ECM proteins decline. Supporting these fundamental structures requires a multifaceted approach targeting both production and preservation of key proteins.

Collagen and elastin form the scaffolding of youthful skin, but production declines with age. To support protein structure and resilience:

• Collagen peptides (oral): Clinically shown to improve hydration and elasticity, and reduce wrinkle depth. ⁽³⁾
• Copper peptides (GHK-Cu): These powerful peptides stimulate collagen, elastin, and glycosaminoglycans, improve skin thickness, and support wound healing and microvascular health. A clinical trial demonstrated copper peptide serums reduced wrinkle volume by 50 to 55 per cent and depth by 30 per cent. 
• Vitamin C: Essential for stabilizing and synthesizing collagen; has additive protective effects.
• Silica & MSM: Support connective tissue health and maintain skin elasticity.

2. Nutrition and targeted supplements for skin health

Skin requires specific nutrients for optimal function. The dermis and epidermis contain concentrated levels of certain vitamins and minerals that serve as cofactors for crucial enzymatic reactions involved in skin barrier function, antioxidant defence, and cellular repair.

A well-nourished body creates glowing skin. Supplements that make a difference:

• Zinc: Promotes barrier repair, reduces breakout frequency, and supports healing.
• Vitamin A (retinol/palmitate): Enhances cell turnover and barrier function.
• Omega-3s (EPA/DHA): Boost hydration, reduce inflammation, strengthen barrier function.
• Astaxanthin & polyphenols (green tea, resveratrol): Protect from oxidative and UV damage.
• Probiotics & prebiotics/fibre: Balance the gut-skin immune axis and calm inflammation.

3. Hormones, stress, and skin resilience

Hormonal changes during perimenopause and menopause profoundly impact skin structure and function. Estrogen affects nearly every aspect of skin biology, from hydration and thickness to wound healing and immune function. Understanding this relationship helps develop targeted support strategies.

Midlife brings hormonal shifts that significantly affect the skin:

• Phytoestrogens like flax and fermented soy support skin hydration and thickness with gentler hormonal effects.
• Adaptogens (e.g., ashwagandha, rhodiola) help balance cortisol—high levels degrade collagen and impair skin repair.
• Magnesium glycinate supports stress response, relaxation, and cellular repair.

4. Skin-gut-immune connection

Recent research has revealed intricate communication pathways between the gut microbiome, immune system, and skin. This axis explains why digestive health so profoundly affects skin appearance and function. Supporting this connection requires a systematic approach to both gut and skin health.

Skin health reflects internal balance. Research shows a direct gut–skin immune axis:

• Gut imbalances (dysbiosis, leaky gut) often manifest as rosacea, acne, eczema, or premature aging.
• Support strategies: Remove inflammatory foods; add fermented foods, probiotics, zinc, and glutamine to strengthen gut integrity and reduce systemic inflammation.

5. Smart sun exposure and vitamin D optimization

The relationship between sun exposure and skin health is more nuanced than previously thought. While photoaging remains a concern, completely avoiding sun exposure may deprive skin of beneficial effects on immunity, vitamin D production, and circadian rhythm regulation.

Sunlight isn’t the enemy—balance is. While sunscreen is important for long exposure, many contain endocrine-disrupting chemicals. A more nuanced approach:

• Gentle sun exposure (morning/late afternoon) supports vitamin D, immune function, mood, and circadian rhythms; burns—not sun—cause damage.
• Nutrients like astaxanthin and omega-3s provide internal photoprotection.
• For extended outdoor exposure, use non-toxic mineral sunscreens (zinc oxide, titanium dioxide) to minimize toxic overload.

6. Minimize toxic load in skincare

The average woman applies dozens of chemicals to her skin daily through personal care products. The cumulative effect of this chemical exposure can impact hormonal balance and cellular function. Understanding ingredient safety and choosing cleaner alternatives becomes increasingly important with age.

Every product adds to your chemical burden. Avoid parabens, phthalates, synthetic fragrances, and unnecessary fillers. Opt for clean, transparent formulations with natural or minimally processed ingredients that deliver real function without compromising health. The Environmental Working Group has a great online resource called SkinDeep, that will analyze the ingredient labels of thousands of personal care products.

7. Lifestyle biohacks for timeless skin

Modern research reveals how lifestyle factors influence skin aging through multiple pathways, including inflammation, oxidative stress, and cellular repair mechanisms. Implementing evidence-based practices can significantly impact skin health outcomes.

Daily habits that cultivate resilience include:

• Prioritizing sleep to support growth hormone and repair.
• Exercise for circulation, lymph flow, and delivery of nutrients to skin.
• Red/NIR light therapy to enhance mitochondrial function and collagen.
• Cold exposure for circulation and peri-follicular tone.
• Gratitude and mindfulness practices—daily gratitude reduces cortisol and strengthens skin repair pathways.

Supporting aging skin requires a comprehensive approach that addresses both internal and external factors. Rather than resisting natural changes, prioritize optimizing your skin’s function through evidence-based methods that enhance its natural ability to renew and repair. This means aligning your skincare, nutrition, and lifestyle choices with the biological realities of aging. With consistent care rooted in science, healthy and resilient skin remains achievable at every stage of life.
