La Roche Posay Pure Vitamin C12 Serum

La Roche-Posay Pure Vitamin C12 Serum is a 30 ml treatment containing 12% pure vitamin C, and the concentration is the headline. Vitamin C is among the most evidence-backed ingredients in skincare, acting as an antioxidant to neutralise the free radical damage caused by sun and pollution while brightening dullness, fading dark spots and supporting firmness — addressing radiance, tone and ageing together. A 12% concentration of pure ascorbic acid is a serious, results-focused level rather than a token inclusion, which is what separates an effective vitamin C from a marketing one. The formula also includes salicylic acid to refine texture and hyaluronic acid for hydration, and is developed to be tolerable on sensitive skin, which is the usual limiting factor with high-strength vitamin C. Skin looks brighter, smoother and more even over consistent use. Apply a few drops to clean skin in the morning before moisturiser and sunscreen. Some tingling initially is normal. Daily sunscreen is essential to protect the results.
