Retinoids: The Gold Standard
Retinoids boost collagen production and accelerate cell turnover. Clinical studies show a 30% reduction in fine lines after 12 weeks.
Vitamin C: Antioxidant Powerhouse
Ascorbic acid neutralizes free radicals, brightens skin, and supports melanin regulation. A 15% serum applied twice daily improves skin texture.
Peptides: The Building Blocks
Short chains of amino acids signal the skin to produce collagen. Studies indicate a 20% increase in firmness after 8 weeks.

Hyaluronic Acid: The Hydration Hero
Its ability to hold up to 1,000 times its weight in water keeps skin plump and reduces the appearance of wrinkles.
