Start twice weekly for 2 weeks. Then every other day. Then daily if tolerated.
What is retinol?
The most evidence-backed anti-ageing active on earth. What it is, what it does, and which Australian formulas deserve the shelf space.
Retinol is a form of vitamin A that converts in the skin to retinoic acid — the active form that triggers skin cell turnover, collagen production, and pigmentation regulation.
It's the single most-studied anti-ageing topical active, with decades of peer-reviewed research backing claims on wrinkles, pigmentation, texture, and acne.
Results take 12-16 weeks of consistent use. The first 2-4 weeks can include mild 'retinisation' — flakiness, sensitivity, initial worsening before improvement.
The method
02.
Apply at night, after cleansing
Pea-sized amount spread across face. Apply to dry skin (wet skin amplifies absorption and irritation).
Follow with moisturiser. Consider a 'buffer' — applying moisturiser first — if extremely sensitive.
03.
Never mix with vitamin C or AHA/BHA
Retinol at night. Vitamin C in morning. Exfoliating acids on non-retinol nights.
Mixing in same routine reduces efficacy and increases irritation.
04.
Non-negotiable: daily SPF
Retinol thins the stratum corneum, making skin more photo-sensitive.
Without daily SPF, retinol accelerates sun damage rather than preventing it.
