Vitamin C

Vitamin C is a core brightening ingredient for dull, uneven-looking skin and post-breakout marks. This collection brings together vitamin C-led serums, creams, toner pads, masks, cleansers, and SPF steps selected for radiance support without turning the page into a single dark-spots claim. You will also see formulas paired with ingredients such as glutathione, niacinamide, collagen, and citrus extracts, which commonly support a more even-looking tone and daily antioxidant care. The assortment spans lightweight daily serums, treatment creams, pad formats, and protective finish steps, so it works well for building a targeted routine around tone, texture, and glow. Protoclinical curates vitamin C products with an evidence-led, protocol-oriented lens, helping you choose the right format for a brighter routine while keeping barrier support and consistent sunscreen use in view.
