Retinol 0.5% in Squalane Serum
Mid-strength retinol in squalane for anti-aging and cell turnover.
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 — with a focus on anti-aging.

Best Season to Use
Richer formula best suited for cold, dry months when the skin barrier needs extra support.
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.
