The Arencia Retinal Booster Shot is a high-potency night serum formulated for skin that needs a real boost. Powered by Retinal (200ppm) — a more effective, faster-converting form of Vitamin A — it works overnight to visibly smooth texture, refine pores, and support firmer-looking skin. Paired with Caffeine, Ectoin, and a full Barrier Complex, it delivers results without compromising comfort.

Fragrance-free, vegan, and cruelty-free. Made in Korea.

• Rejuvenating night serum — apply as the last step of your evening routine
• Retinal (200ppm) converts to retinoic acid 11x faster than retinol for stronger, faster results
• Suitable for skin already accustomed to active ingredients — if new to retinal, start every other night
• Always follow with SPF the next morning — retinal increases UV sensitivity
• 49 skin-loving ingredients including Niacinamide, Adenosine, Allantoin and Panthenol

• For external use only. Avoid contact with eyes. If contact occurs, rinse thoroughly with water.
• Retinal increases skin sensitivity to UV — always apply broad-spectrum SPF the following morning.
• If you are new to retinal or active ingredients, start by using every other night and increase gradually as skin adjusts.
• Not recommended for use during pregnancy or breastfeeding. Consult your doctor before use.
• Do not use alongside other high-strength actives (e.g. AHA/BHA, Vitamin C) in the same routine without consulting a skincare professional.
• Discontinue use if irritation, redness, or discomfort occurs and consult a dermatologist.
• Keep out of reach of children. Store in a cool, dry place away from direct sunlight.
• Perform a patch test before first use, especially if you have sensitive skin.
