Arencia Retinal Booster Shot is a 30 mL night serum with retinal 200 ppm (0.02%), caffeine, ectoin and a ceramide/cholesterol/fatty-acid barrier complex for visible lines, texture and firmness.

Why it is used:
For adult skin gradually introducing a vitamin-A cosmetic to improve photoageing and uneven texture; not for immediate results and irritation risk requires slow use.

Ingredients and components:
Retinal 200 ppm = 0.02%, caffeine, ectoin, niacinamide, bakuchiol, panthenol, Centella, peptides and a barrier-lipid complex with ceramide, cholesterol and fatty acids. Use the current pack for the complete INCI.

How to use:
At night only, apply a pea-sized amount to completely dry face after cleansing, avoiding eyes, lips and nose creases. Start 2–3 nights weekly or every other night, then increase only if tolerated; moisturise. Do not use the same night as other retinoids or strong exfoliating acids. Use SPF 30+ every morning.

Potential side effects and precautions:
Expected adjustment can include dryness, redness, peeling, burning or temporary breakouts. Stop for severe swelling, blistering or persistent pain. Avoid during pregnancy or breastfeeding unless a clinician specifically approves topical vitamin A.

Cosmetic product for external use only; it is not intended to diagnose or treat disease. The ingredient list on the physical pack is the final reference because formulas may be updated. Stop use if persistent irritation occurs.
