Retinol 0.5 Refining Night Cream
SkinCeuticals is the gold standard for pure, stabilized retinol. Their formulation uses a specialized delivery system based on the skin's lipid structure to ensure the retinol is absorbed effectively without the heavy irritation often associated with high-potency actives.
Quality & Materials
Contains 0.5% pure retinol. The formulation is paraben-, fragrance-, and dye-free. It includes a soothing complex to minimize the 'retinization' period.
Evidence & Testing
Backed by L'Oreal's extensive R&D, this product line has decades of data supporting its efficacy in reducing fine lines and hyperpigmentation.
Brand Transparency
While they don't release full COAs to consumers, they are one of the few brands that disclose the exact percentage of pure retinol and conduct rigorous stability testing.
Value Assessment
High price point ($82), but the stability ensures the last drop is as effective as the first, unlike jar-packaged retinols which oxidize quickly.
Why Not Alternatives?
Many 'prestige' brands use retinol derivatives (like retinyl palmitate) which are far less effective. SkinCeuticals uses pure retinol in an airless pump with a soothing complex of bisabolol and boswellia serrata that competitors often omit to save costs.
