How it works

Retinol is a vitamin A derivative that speeds up cell turnover and stimulates collagen production. At 2.5% concentration, this serum aims to provide a noticeable improvement in texture and tone while being formulated to balance potency with tolerability when used carefully.

Directions for use

1. Patch test before first full-face application.
2. Start slowly: apply 1–2 nights per week for the first 2–4 weeks, then increase frequency as tolerated.
3. At night, after cleansing and toning, apply a pea-sized amount to the face (avoid direct eye area). Follow with a moisturizer if needed.
4. Always use broad-spectrum sunscreen during the day while using retinoids.

Precautions & tips

• Avoid use during pregnancy or breastfeeding. Consult a healthcare professional if unsure.
• Avoid combining with other strong actives (e.g., professional-strength AHA/BHA peels, benzoyl peroxide) unless directed by a professional.
• Mild redness, peeling or sensitivity can occur as skin adapts — reduce frequency if irritation is severe and discontinue if necessary.
• Store in a cool, dry place away from direct sunlight; keep bottle closed when not in use.

Texture & finish

Lightweight serum that absorbs quickly; designed to be layered under a moisturizer. Individual experiences with dryness or mild peeling may vary.
