Principia 3-Step Advanced Skin Renewal Kit – Vitamin C, Retinol & HA

Upgrade your skincare routine with the Principia 3-Step Advanced Skin Renewal Kit, a complete transformative system designed to brighten, firm, repair and deeply hydrate the skin. Powered by three high-performance formulas—10% Vitamin C + Ferulic Acid, 0.3% Retinol + Vitamin E, and 2% Hyaluronic Acid + Vitamin B5—this kit delivers visible improvements in clarity, texture, fine lines, firmness, moisture and radiance.

Start your day with a powerful antioxidant boost using VC-10 (Vitamin C 10% + 0.5% Ferulic Acid). This serum brightens dull skin, fades dark spots, evens tone and protects against environmental damage while enhancing skin luminosity and smoothness.

At night, renew and refine your complexion with Rn-0.3 (Retinol 0.3% + Vitamin E). This advanced retinoid accelerates cell turnover, reduces wrinkles, improves elasticity and enhances skin firmness for a more lifted, youthful appearance.

Complete hydration and barrier repair are delivered with AH-2 (Hyaluronic Acid 2% + Vitamin B5). This serum draws moisture deep into the skin, plumps fine lines and restores softness, making your complexion smooth, supple and revitalized.

Together, these three serums create a synergistic routine that targets all major visible signs of aging—radiance loss, uneven tone, fine lines, wrinkles, dehydration and loss of firmness—leaving your skin noticeably healthier and more radiant day after day.
