Whether you're just starting your anti-aging routine or leveling up an existing one, this serum meets you where you are and delivers visible results you can feel confident about.

What's Working For Your Skin

• 1% Retinol EX — A clinically recognized concentration that visibly reduces fine lines, wrinkles, and uneven texture over time. Your skin's renewal process, accelerated.
• 5 Peptides — Strengthen the skin barrier and improve firmness, helping skin look and feel more resilient with every use
• 5 Ceramides — Lock in moisture and reinforce your skin's natural protective barrier, so hydration stays where it belongs
• TECA (Centella Asiatica Extract) — Calms inflammation and protects skin, making this formula surprisingly gentle for a 1% retinol serum
• Lightweight milky texture — Fast-absorbing and non-greasy, so it layers beautifully under your moisturizer without heaviness

How To Use

1. Cleanse and dry your skin thoroughly before applying
2. Dispense 2–3 drops onto your palm and gently pat onto face and neck
3. Evening use: Apply after cleansing, before moisturizer — let retinol work its magic overnight
4. Daytime use: Always follow with SPF to protect skin from UV sensitivity
5. New to retinol? Start 2–3 nights per week and build up gradually as your skin adjusts

Sensitive skin tip: Patch test on a small area before full-face application.
