The Ordinary Retinol 0.5% in Squalane is a moderate-strength, water-free serum that pairs 0.5% pure retinol with nourishing squalane to soften the look of fine lines, uneven texture and dark spots. Designed for intermediate retinol users, this lightweight anti-aging serum supports natural skin renewal while the squalane base cushions the skin against the dryness that stronger retinoids can bring.

Why This Retinol Serum Works

Retinol is a well-studied form of vitamin A that encourages skin cell turnover, helping to smooth texture and soften the look of lines over time. At 0.5%, this formula sits between the beginner 0.2% and the high-strength 1%, making it a natural next step once your skin has adjusted to a lower concentration. The water-free squalane base keeps delivery gentle and hydrating.

Ideal For

This serum is best suited to those with some retinol experience who want a mid-strength option to target early signs of aging, dullness and uneven texture. If you are completely new to retinol, the 0.2% is a gentler starting point, while very sensitive skin may prefer a Granactive Retinoid. Note that it is not intended as an acne treatment.
