Retinol Night Cream with Vitamin C & Hyaluronic Acid

Retinol — A vitamin-A derivative that speeds cell turnover — the best-evidenced ingredient for fine lines and texture over months of nightly use. The strength is not printed, so we cannot judge the dose; that counts against the brand. Works from ~0.3%. OTC cap 1%. Give it 12 weeks minimum; best gains around 6 months. Best for Oily, Combination, Normal. Powerful but irritating early on. Oily and normal skin adapt fastest; dry and sensitive skin should start low and buffer with moisturiser.

Ascorbic Acid — An antioxidant that brightens dullness and helps defend against daytime free-radical damage — a morning serum ingredient. The strength is not printed, so we cannot judge the dose; that counts against the brand. Works from ~10%. OTC cap 20%. Give it 8–12 weeks for dark spots. Best for Normal, Combination, Oily. A morning antioxidant that brightens. High-strength L-ascorbic acid at a low pH can sting sensitive skin — go for a gentler derivative.

Sodium Hyaluronate — A humectant that holds water in the upper skin — pure hydration, tolerated by essentially everyone, at any concentration. The strength is not printed, so we cannot judge the dose; that counts against the brand. Works from ~1%. Works Ongoing while you use it; no weeks-long build-up to wait for. Suits all skin types. Pure hydration — suits everyone, and dry or dehydrated skin most of all. Apply on damp skin and seal it in.
