Arencia's Vitamin C Booster Shot is a 30ml Korean serum built on a stabilized vitamin C complex, supported by niacinamide, glutathione, and vitamin E. The formulation logic is that plain vitamin C oxidizes quickly and can irritate, so the additions do real work: niacinamide supports the skin barrier and helps offset the sting, while glutathione and vitamin E act as antioxidants alongside the vitamin C rather than duplicating it. It targets the look of dark spots, uneven tone, fine lines, and the general dullness that vitamin C is usually bought for. Best fit for anyone building a brightening routine, K-beauty regulars, and people whose skin has found straight L-ascorbic acid too harsh.
Pros
- Stabilized vitamin C complex rather than a formula that oxidizes in weeks
- Niacinamide supports the skin barrier and helps offset vitamin C irritation
- Glutathione and vitamin E add antioxidant support against daily environmental stress
- 30ml at this price undercuts most Western brightening serums by a wide margin
Cons
- Brightening actives work gradually, so expect this to be a months-long routine rather than a fast fix
Frequently asked questions
When in my routine does this go?
Serums like this are typically applied after cleansing and before moisturizer. Vitamin C is most commonly used in the morning, followed by sunscreen.
Can I use it with retinol?
Many people separate them, using vitamin C in the morning and retinol at night, to reduce the chance of irritation from layering both actives at once.
Is it irritating for sensitive skin?
It pairs vitamin C with niacinamide, which is generally included to support the barrier and soften the sting of straight vitamin C. Patch testing first is still the sensible move.
How big is the bottle?
30ml, which is 1.01 fl oz, the standard serum size.
