Arencia

Vitamin C Booster Shot

For dark spots, dullness, and uneven skin tone.

The concentrated vitamin C serum from Arencia, a Korean brand built on artisanal methods and modern ingredient science. The hero is a dual vitamin C complex: 50,000ppm of 3-O-Ethyl Ascorbic Acid (a highly stable, well-penetrating vitamin C derivative) paired with pure vitamin C for both immediate and long-term brightening. That combination is what sets this apart. Pure vitamin C fades pigment fast but oxidises quickly, while 3-O-Ethyl Ascorbic Acid stays stable through the bottle life and delivers a sustained brightening effect. Together, they hit stubborn dark spots and dullness from two angles.

Around the vitamin C core, the formula stacks glutathione (the master antioxidant that blocks melanin production at the source) plus niacinamide for tone clarity, and vitamin E for antioxidant support. Panthenol and allantoin keep the formula gentle enough for daily use, and the texture is lightweight and fast-absorbing with no stickiness. Multi-use by design. Works as a face serum, an eye brightener, and a spot treatment on stubborn pigmentation. The kind of vitamin C product that suits customers who have found pure ascorbic acid too irritating but still want serious brightening credentials.

Key Ingredients
Dual Vitamin C Complex (3-O-Ethyl Ascorbic Acid 50,000ppm plus Pure Vitamin C) The hero of the formula. 3-O-Ethyl Ascorbic Acid at 5% is a stable, well-penetrating vitamin C derivative that stays effective through the bottle life, paired with pure vitamin C for immediate and long-term brightening. Fades dark spots from two angles. Glutathione The master antioxidant that blocks melanin production at the source. Works synergistically with vitamin C for amplified brightening and a clearer, more even tone. Niacinamide Brightens, evens tone, refines pores, and strengthens the skin barrier. Adds another brightening pathway alongside the vitamin C core. Vitamin E (Tocopherol) A protective antioxidant that helps stabilise the vitamin C and defends against free radical damage. The classic partner to vitamin C for amplified antioxidant results. Panthenol and Allantoin A soothing duo that keeps the formula gentle even at these high active concentrations. Calms surface reactivity and supports the barrier during brightening treatment.
How to Use
Apply to clean, dry skin morning or evening. Take a small amount and gently pat over the face, focusing on areas with dullness, dark spots, or hyperpigmentation. Let the serum absorb for around 30 seconds before following with moisturiser. For daytime, always finish with SPF (essential when using brightening actives). If new to vitamin C, start every other day for the first two weeks and build up to daily use as your skin adjusts. Do not layer with retinol or strong exfoliants on the same day. Tip: This one works genuinely well as a targeted eye-brightener too. Take a rice-grain amount, gently pat around the orbital bone with your ring finger, and use it on stubborn under-eye dark circles as well as on the face. Also works as a spot treatment. Dab an extra thin layer directly onto persistent dark spots for a targeted brightening approach.
