ARENCIA

ARENCIA Vitamin C Booster Shot is the brightening half of the Booster Shot pair, and the sensible way to use vitamin C if pure L-ascorbic acid has ever stung or gone orange on you. It is built on 3-O-ethyl ascorbic acid at 50,000 ppm — a stable derivative that does not oxidise in the bottle.

Four more vitamin C forms sit behind it, with glutathione, tocopherol and niacinamide rounding out the antioxidant side. The texture is a light cream-serum that absorbs fast and does not pill, so it also works as a quick brightening base before makeup.

• 3-O-Ethyl Ascorbic Acid 50,000 ppm — stable vitamin C, no oxidation
• Ascorbyl Glucoside & Sodium Ascorbyl Phosphate — layered vitamin C delivery
• Glutathione & Tocopherol — antioxidant support
• Niacinamide & Adenosine — tone and fine lines
• Panthenol & Allantoin — keep it comfortable on sensitive skin

Un sérum éclat à la vitamine C stabilisée, contre les taches et le teint terne. 30 ml.

ARENCIA NAD Booster Shot brings NAD+ — the coenzyme behind the longevity-supplement boom — into a topical treatment. Despite the "shot" in the name it is not a watery serum but a light cream-textured treatment, applied before or in place of your moisturizer.

What makes it worth the shelf space is what sits around the NAD+: a five-ceramide barrier complex and a deep peptide stack including copper tripeptide-1 and palmitoyl pentapeptide-4. It is aimed at skin that looks tired and depleted rather than at any single concern.

• NAD+ Complex — with NMN and adenosine triphosphate alongside it
• 5 Ceramides (NP, NS, AS, AP, EOP) — a full barrier-lipid set
• Peptide Stack — copper tripeptide-1, acetyl hexapeptide-8, palmitoyl pentapeptide-4
• Resveratrol & Guaiazulene — antioxidant and soothing
• Squalane, Niacinamide & Panthenol — comfort, tone and hydration

Un soin au NAD+ et aux céramides, pour les peaux fatiguées et dévitalisées. Texture crème légère, 30 ml.

ARENCIA Retinal Booster Shot uses retinal — retinaldehyde — rather than retinol. Retinal is one conversion step closer to retinoic acid, which is why it works faster at a lower concentration; here it sits at 200 ppm, a level built for people starting out rather than for tolerance-building veterans.

What makes it wearable is what surrounds the retinal: a ceramide-cholesterol-fatty-acid barrier complex, ectoin, bakuchiol and centella. Caffeine brightens a tired-looking face. The texture is a light cream-serum that layers under moisturizer without pilling.

• Retinal 200 ppm — faster-acting than retinol, at a beginner-friendly level
• Ceramide NP, Cholesterol & Fatty Acids — barrier complex that buffers the retinal
• Ectoin & Bakuchiol — defend against dryness, support the wrinkle work
• Caffeine & Niacinamide — brighten a dull, tired complexion
• Centella Asiatica & Peptides — soothe and support resilience
