Arencia Retinal Booster Shot · 30ml

Arencia Retinal Booster Shot · 30ml

Your overnight skin transformation, bottled. This rejuvenating night serum is powered by Retinal, Caffeine, and Ectoin to visibly smooth texture, refine pores, and support firmer-looking skin — balanced with skin-barrier lipids and peptides to deliver deep hydration and resilience for a refreshed, even complexion by morning. 

The Retin-A Complex™ — next-generation Vitamin A delivery:

At the heart of the formula is Arencia's proprietary Retin-A Complex™ at 2%, designed to refine pores, improve elasticity, and smooth fine lines — delivered deep into the skin through LDH nano-encapsulation and multi-liposome technology for visible skin renewal with minimal irritation. This dual delivery system means retinal is both more stable in the formula and more effective once it reaches the skin — a meaningful upgrade over standard retinol serums. 

The supporting powerhouse complex — 49 active ingredients:

Caffeine energises dull, tired skin and helps reduce the look of puffiness for a smoother surface. It's not just a wakeup ingredient — applied topically, it stimulates microcirculation and visibly revives fatigued, lacklustre skin overnight.

Ectoin — a powerful stress-protect molecule — defends against dryness and environmental damage while maintaining the skin's moisture balance, making it particularly valuable for anyone whose skin reacts to stronger actives.

A Barrier Complex of Ceramide NP, Cholesterol, and Fatty Acids work together to strengthen the skin barrier and lock in hydration for long-lasting comfort — essentially rebuilding the skin's natural lipid matrix from within. 

An impressive peptide complex rounds out the formula — including Palmitoyl Pentapeptide-4, Hexapeptide-2, Hexapeptide-9, Tripeptide-1, Pentapeptide-3, Palmitoyl Tripeptide-1, Palmitoyl Tripeptide-5, Acetyl Hexapeptide-8, and Copper Tripeptide-1 — a comprehensive multi-peptide blend that supports collagen production, firming, and skin resilience from multiple angles simultaneously.

Bakuchiol, Centella Asiatica, Niacinamide, Allantoin, and Panthenol complete the formula — soothing, brightening, and hydrating while the retinal does its overnight renewal work.

WHY SEOULMA RECOMMENDS IT

The Arencia Retinal Booster Shot sits in a very specific sweet spot that's hard to find: a high-potency retinal treatment that promotes a plump and youthful complexion, formulated with the exclusive Retin-A Complex alongside soothing ingredients like Centella Asiatica, Ceramides, and Ectoin to counter any irritation that may arise — so you actually get the results without the suffering.

What distinguishes this from other retinal serums in our range is the sheer depth of its supporting cast. With 9 different peptides, a complete barrier lipid complex, and an anti-fatigue Caffeine and Ectoin duo, this isn't just a retinal serum with some added moisturisers. It's a comprehensive overnight treatment designed to rebuild and renew the skin on every level — texture, firmness, tone, and hydration — all in a single step.

It also pairs beautifully with the Arencia Vitamin C Booster Shot as a day-and-night duo: use the Vitamin C Booster Shot during the day with SPF, and the Retinal Booster Shot at night — together targeting dullness, pigmentation, ageing, and texture around the clock. 

For retinal beginners, Bakuchiol in the formula provides a gentle head start — it has been shown to boost retinoid activity and help stabilise retinal, meaning even first-time users tend to adapt more comfortably than with retinal serums formulated without it.

How to use: First 2 weeks: Apply every other evening to allow skin to adjust. After 2 weeks: Use daily in the evening, applying evenly over the face or targeting dull, textured areas. Always follow the next morning with SPF — non-negotiable with retinal use.
