Retinol (vitamin A) is the only over-the-counter skincare ingredient that directly stimulates collagen production at the dermal level. Every other anti-ageing ingredient either prevents damage (SPF), reduces inflammation (niacinamide, azelaic acid), or exfoliates dead cells (AHAs). Retinol is the only one that creates new collagen — the protein responsible for skin firmness, elasticity, and the visible reduction of fine lines.
Prescription retinoids (tretinoin) are 20-50x more potent than over-the-counter retinol. They work through the same mechanism but at a speed and depth that produces faster results and more significant initial irritation. For men starting for the first time, OTC retinol at 0.025-0.1% is the appropriate entry point.
The majority of men who abandon retinol do so in weeks 2-4 because of the purging period and initial irritation. Both are predictable and both can be managed with the correct introduction protocol.
Weeks 1-4: 0.025-0.05% retinol, applied to completely dry skin (wait 20 minutes after cleansing), two nights per week only. Apply a pea-sized amount. Apply your moisturiser over the retinol immediately after.
Weeks 5-8: Increase to three nights per week if tolerating well (no significant flaking or redness).
Weeks 9-16: Increase to 0.1% if the lower concentration is well-tolerated. Increase frequency to four nights per week.
Month 4 onwards: 0.1% every other night. Introduce 0.3-0.5% at month 6-9 if desired.
In weeks 2-6, existing comedones (blocked follicles) clear rapidly as cell turnover accelerates. This temporarily produces what looks like a breakout. This is not a negative reaction — it is the routine working. The purging period resolves within 4-8 weeks and should not prompt you to stop using the product.
Always apply to dry skin. Moisture dramatically increases retinol penetration and therefore irritation. Wait at least 20 minutes after washing before applying.
Always use SPF the following morning. Retinol significantly increases photosensitivity. UV exposure will cause the skin to produce melanin in response to inflammation — exactly undoing retinol's hyperpigmentation benefits.
Do not use with benzoyl peroxide. Benzoyl peroxide oxidises and deactivates retinol. Use them on alternate nights.
Store in a dark bottle, away from light. Retinol degrades when exposed to light and air.
