About this product
The Ordinary Retinol 0.5% in Squalane delivers a moderate concentration of pure retinol dispersed in a base of stable squalane oil. Squalane acts as a carrier that improves retinol stability and reduces the potential for irritation. Suitable for those who have built up a tolerance to lower retinol concentrations and are seeking more noticeable anti-aging effects.
Best for normal, combination, dry skin looking to address fine lines & wrinkles, uneven texture, dullness — with a focus on anti-aging.

Dermatologist Note
0.5% retinol is a mid-strength formulation — strong enough for noticeable anti-ageing effects (peer-reviewed evidence shows retinoids increase collagen synthesis and accelerate cell turnover) while being manageable for most non-sensitive skin types. The squalane base minimises the typical dryness and peeling associated with retinol. Always use SPF the following morning.
Based on published clinical literature and dermatological research.
Best Season to Use
Richer formula best suited for cold, dry months when the skin barrier needs extra support.
