Retinol 0.5 Refining Night Cream
SkinCeuticals is the gold standard for stabilized retinol delivery. Their formulation uses a specialized encapsulation technology that ensures the retinol remains potent until it hits the skin, preventing the oxidation that renders most drugstore retinols useless.
Quality & Materials
0.5% pure retinol. Uses a 'steady-release' delivery system to minimize irritation. Free of parabens, fragrance, and gluten.
Evidence & Testing
SkinCeuticals conducts extensive third-party clinical trials on their specific finished formulations, not just the raw ingredients. Results show significant improvement in fine lines and skin tone.
Brand Transparency
Clearly states the active retinol percentage. While they don't release full COAs to consumers, their clinical data is published in peer-reviewed journals.
Value Assessment
High entry price, but because the product is stabilized, you use less and the product remains effective until the last drop, unlike unstabilized alternatives.
Why Not Alternatives?
While cheaper retinols exist, they often degrade in the tube due to poor packaging and lack of stabilization. SkinCeuticals uses a dual-shield delivery system and air-tight packaging that ensures the 0.5% concentration is actually delivered to the dermis.
