This serum combines retinol, niacinamide, glycolic acid, and ferulic acid in a fragrance-free formula designed to support skin renewal and resilience. Retinol works to encourage cell turnover and smooth the appearance of fine lines and uneven texture. Niacinamide helps strengthen the skin barrier and improve overall tone, while glycolic acid provides gentle exfoliation to refine surface dullness. Ferulic acid acts as an antioxidant to help protect against environmental stressors. The formulation is water-based and lightweight, allowing it to absorb quickly without leaving a greasy residue. It is suitable for those looking to incorporate multiple active ingredients into a single step, though users new to retinol or acids may wish to start with lower frequency to assess tolerance. The product is free of added fragrances, making it a potential option for sensitive or easily irritated skin types. With a volume of 2 fluid ounces, this serum is intended for nightly use as part of a regular skincare routine, typically applied after cleansing and before moisturizer. It is not formulated to treat specific skin conditions or deliver instant results, but rather to offer gradual support for a more even and refined complexion over consistent use. As with any active ingredient, patch testing is recommended before full application. This serum does not claim to replace professional dermatological treatments or to address severe skin concerns. Its primary focus is on delivering a balanced blend of commonly used skincare actives in a straightforward, no-frills format.
