Advanced Retinal Care for Smoother, Firmer-Looking Skin

Arencia Retinal Booster Shot is a concentrated nighttime skincare treatment developed for rough, textured or tired-looking skin. Arencia describes it as a rejuvenating night serum designed to improve the appearance of texture, pores and firmness while providing complementary barrier and hydration care.

Retinal – Advanced Vitamin A Care

The formula contains Retinal (Vitamin A), a retinoid used in the product to target uneven-looking texture and elasticity while reducing the visible signs of tired-looking skin. Arencia's official duo page specifies Retinal 200 ppm for the Retinal Booster Shot.

Caffeine for Tired-Looking Skin

Caffeine complements the Retinal formula by helping refresh dull, tired-looking skin and reduce the appearance of puffiness, contributing to a smoother and more energized appearance.

Ectoin for Moisture & Skin Comfort

The formula also features Ectoin, which Arencia highlights for helping protect against dryness and environmental stress while supporting the skin's moisture balance.

Skin Barrier Complex

Unlike a simple active-only retinal serum, Arencia combines the active formula with a barrier-supporting complex containing Ceramide NP, Cholesterol and Fatty Acids. These ingredients work together to support the skin barrier and help lock in moisture for greater comfort.

Peptide-Enriched Formula

The formula is additionally balanced with peptides, providing complementary care for hydration, resilience and firmer-looking skin. Arencia specifically describes the Retinal Booster Shot as containing barrier lipids and peptides.

How to Use

For nighttime use, apply a thin layer to clean, dry skin, either over the entire face or specifically to textured/problem areas, and follow with moisturizer. For people new to retinal/retinoids, Arencia recommends starting slowly—around 2–3 nights per week or every other day—and gradually increasing use as the skin adjusts.

Arencia advises performing a patch test before first use, avoiding combination with strong actives or exfoliating products, and using sunscreen during the daytime while using retinoids. The brand also advises against layering its Vitamin C Booster Shot and Retinal Booster Shot in the same routine.
