Ingredient

Retinal

The most potent over-the-counter form of vitamin A, one step closer to its active form in skin than retinol — meaning it works faster for smoothing texture, reducing fine lines, and fading pigmentation. Start at 0.05% to let skin adjust, then build to 0.1% over several weeks. Use only at night, and always apply SPF the following morning — it increases the skin's sensitivity to sun.
