Skincare for Mature Skin (40s and Beyond)

Skin in the 40s and beyond changes in specific, well-understood ways — and most of those changes respond well to the same core ingredients used at any age, just applied with a better understanding of what is happening. The biggest mistake is abandoning the fundamentals in favour of expensive anti-aging products that promise more than the evidence supports.

• What changes: collagen production slows from the late 20s onward. Post-menopausal oestrogen decline accelerates barrier thinning, reduces skin's water-holding capacity, and decreases collagen synthesis significantly — often producing rapid visible changes in skin texture and firmness.
• Retinoids: the most evidence-backed anti-aging ingredient available. Retinol (OTC) and tretinoin (prescription) are both shown in clinical trials to reduce fine lines, improve texture, and increase collagen production. Not optional for mature skin if tolerated.
• SPF: cumulative UV exposure is the single largest external cause of visible aging. The benefit of daily SPF does not diminish with age — it compounds. Starting in your 40s is not too late.
• Peptides: modest evidence for some peptides (matrixyl/palmitoyl pentapeptide, argireline) in improving skin firmness and fine lines. Less evidence than retinoids, but well tolerated and worth including in a routine.
• Collagen supplements: hydrolysed collagen peptides have emerging evidence (small RCTs) for improving skin elasticity and hydration — not equivalent to topical retinoids, but low risk and reasonable as an adjunct.
• Rich moisturisers become more important: barrier function declines with age. Ceramide-rich formulations and occlusives (petrolatum, shea) become more appropriate for mature skin.
