Product details

Arencia Retinal Booster Shot Firming Serum 30ml is a Korean nighttime serum for fine lines and wrinkles, visible pores and uneven texture. Its 0.02% retinal, caffeine and ectoin help skin look smoother, firmer and more refreshed.

The lightweight yellow gel cream spreads easily and absorbs without a heavy, greasy feel. Ceramide NP, cholesterol and moisturizing ingredients help maintain hydration and skin comfort alongside the retinal.

Apply a thin layer to clean, dry skin before moisturizer. Start every other night or less often if you are new to retinoids, and increase only as tolerated. Use broad-spectrum SPF 30 or higher every morning.

Pair your retinal with moisture + daily SPF

Follow the evening serum with a barrier moisturizer, then use sunscreen each morning. Keep strong exfoliants and other retinoids out of the same routine.

Formula, ingredients & use

Why you’ll love it

  • Helps soften the look of fine lines and wrinkles while supporting firmer-looking skin.
  • Refines the appearance of visible pores and uneven texture for a smoother-looking complexion.
  • Caffeine and peptides help refresh tired-looking skin and support a more revitalized appearance.
  • Ectoin, Ceramide NP and cholesterol support moisture balance and skin comfort.
  • The lightweight gel cream spreads easily, absorbs without a heavy feel and dispenses from a precision-tip tube.

Best for

Best for: Fine lines and wrinkles, loss of firmness, visible pores, rough or uneven texture, and tired-looking skin that needs moisture support.

Skin type fit: Suitable for a range of skin types, including normal, combination, oily, dry and mature skin, when retinal is tolerated. If your skin is sensitive or new to retinoids, patch test and start less frequently. Avoid applying to irritated or compromised skin.

What to expect

Format: Retinal treatment serum in a 30ml squeeze tube with a precision tip.
Texture: Yellow, lightweight gel cream that spreads easily.
Finish: Smooth and moisturized, without a heavy, greasy feel.
Scent: No added fragrance is listed in the manufacturer's ingredient list; a natural formula scent may be noticeable.
Routine step: Evening treatment after cleansing and any hydrating toner, before moisturizer. Use sunscreen each morning.

How to use

  1. Use in the evening after cleansing. If you use a hydrating toner, let it absorb and allow skin to dry before applying the retinal serum.
  2. Squeeze out a small amount and spread a thin, even layer over the face or areas of concern. Gently pat to absorb.
  3. Follow with a gentle moisturizer to support hydration and skin comfort.
  4. Start every other night, or less often if you are new to retinoids or easily irritated. Increase only as your skin adjusts. Apply broad-spectrum SPF 30 or higher every morning.

Important safety notes

  • Patch test before first use. Do not apply to broken or irritated skin. Reduce frequency or stop use if persistent redness, stinging or peeling occurs.
  • Avoid direct contact with the eyes; rinse thoroughly with water if contact occurs.
  • Keep the routine gentle. Avoid layering with vitamin C, strong exfoliating acids or other retinoids in the same routine.
  • This contains a vitamin A derivative. Avoid use during pregnancy; ask your healthcare professional before using while breastfeeding.

Key ingredients

  • Retinal 0.02% (200ppm): A vitamin A derivative that helps smooth the look of fine lines and uneven texture while supporting firmer-looking skin.
  • Caffeine: Helps refresh tired-looking skin and reduce the appearance of puffiness.
  • Ectoin: Supports moisture balance and helps keep skin comfortable when it feels dry.
  • Ceramide NP + cholesterol: Barrier-supporting lipids that help maintain moisture and a soft, supple feel.
  • Peptides: Includes Palmitoyl Tripeptide-5, Acetyl Hexapeptide-8 and Copper Tripeptide-1 to support smoother, firmer-looking skin.
  • Glycerin, panthenol + allantoin: Moisturizing and comfort-supporting ingredients that help balance the retinal routine.

  • Best used as an evening treatment, followed by moisturizer and daily morning sunscreen.
  • No added fragrance appears in the ingredient list; a natural formula scent may be noticeable.
  • Made in South Korea. Supplied new and factory sealed.
  • Store in a cool place away from direct sunlight and keep out of reach of children.
