More powerful than Retinol and gentle enough for daily use? Our Mega-A Skin Transforming Serum is powered by clinical-grade Retinal, proven to be 11x more effective than Retinol. This powerhouse serum blends skin-enhancing Retinal with Hyaluronic Acid + Squalane to increase hydration and elasticity while smoothing the look of fine or deep lines. Perfect for all skin types (even sensitive skin) whether you're experienced with retinoids or just getting started. For the healthiest skin, use this serum in the evening and ExfoliKate in the morning to keep skin glowing and bright. Remember, one active product per routine is plenty. As Retinal is an active ingredient, start slowly with usage. Begin with 1-2 x per week, and slowly increase week by week based on skins tolerance. After cleansing, apply 3-4 drops to face, neck, and décolleté, avoiding the eye area. Gentle enough for daytime use - just don't skip the sunscreen.
