Arencia's Vitamin C Booster Serum packs Glutathione, Niacinamide, and Vitamin E into a concentrated 30 ml formula that tackles dullness, uneven tone, and antioxidant stress all at once. It's the kind of serum that earns a permanent spot in your morning routine.
Formulated to deliver visible brightness, defence, and clarity from the very first drop.
Many Vitamin C serums stop at one brightening ingredient. Arencia's booster layers three skin-tone heroes — Vitamin C, Glutathione, and Niacinamide — into a single, fast-absorbing formula so you get more done with fewer steps.
Based on user trials and customer feedback on the Arencia Vitamin C Booster Serum.
After cleansing and toning, press 2–3 drops onto your fingertips and pat gently across your face and neck before your moisturiser. For best results, follow with a broad-spectrum SPF in the morning to protect Vitamin C's brightening work.
Building confidence with clear answers to your concerns.
You can use it once or twice daily — morning and evening are both fine. Most users see the best results from consistent daily use, ideally followed by SPF in the morning.
The formula is designed to be gentle, but if your skin is reactive we'd suggest patch-testing behind the ear or on the inner wrist for a few days before applying to your full face. Start with once-daily use and build from there.
It has a lightweight gel-serum texture that sinks in quickly and leaves no sticky residue. Most users find it completely comfortable under moisturiser, sunscreen, or makeup.
Yes — that's exactly how it's meant to be used. Apply the serum after cleansing and toning, let it absorb for about a minute, then follow with your moisturiser and SPF. It doesn't pill or interfere with other products.
Many users notice a brighter, more even-looking complexion within two weeks of consistent daily use. Significant improvement in dark spots and pigmentation typically becomes more visible after four to six weeks.
Glutathione is a powerful antioxidant that inhibits melanin production, which helps fade existing hyperpigmentation and prevent new dark spots from forming. Paired with Vitamin C, it gives the serum a double-action brightening effect.
It's particularly well suited for dullness, uneven skin tone, dark spots, post-blemish marks, and early signs of environmental ageing. The Niacinamide also helps with visible pores and texture, so it works well for most complexion concerns.
It's generally fine to use alongside other actives, but we'd recommend avoiding applying high-strength acids and this serum at the same time if your skin is prone to sensitivity. A good approach is to use Vitamin C in the morning and your retinol or AHA in the evening to keep your skin comfortable.
Real feedback from real customers.
My skin has genuinely never looked this even. The dark marks from old breakouts have faded noticeably and my complexion has this warm, healthy glow I wasn't expecting so quickly. I'm completely hooked. ✨
I've tried so many Vitamin C serums and most of them either sting or leave a tacky film. This one absorbs instantly and my skin just drinks it up. The brightening effect is real — my colleagues noticed before I said anything.
Lovely lightweight texture and my skin does look more radiant after a fortnight of use. I'm knocking one star off only because the bottle is quite small, but I'll be ordering again without hesitation.
The combination of Vitamin C and Glutathione is doing serious work on my hyperpigmentation. I've been using it every morning under my SPF and the difference in my skin tone is undeniable after about three weeks.
I love how this layers under everything without any fuss — moisturiser, SPF, primer, all on top without a single pill or patch. My skin looks clearer and the texture is noticeably smoother too.
Good serum, genuinely. The glow it gives is subtle but real — not that artificial shimmer, just healthier-looking skin. I'd love a slightly larger size, but the formula itself is lovely.
As someone with melanin-rich skin that marks very easily, finding something that fades dark spots without irritation feels like a win. This serum has calmed my PIH considerably and my skin tone is so much more uniform now.
The texture is honestly one of the nicest I've tried — it feels cooling going on and disappears into skin in seconds. Two weeks in and my forehead and cheeks look noticeably brighter. Very impressed.
Solid brightening serum that doesn't break the bank. I've noticed my complexion looking less dull and my SPF seems to glide on more smoothly since I added this step. Would definitely recommend for anyone tackling uneven tone.
I was skeptical because I'd been disappointed by similar products before, but the Niacinamide in this really does make a difference to my pores. My skin looks tighter and more refined, and the dullness I always had in the morning is just gone.
This is now the first thing I reach for after cleansing. The Glutathione and Vitamin C combo has visibly faded the sunspots on my cheeks and my skin has this natural lit-from-within look that I'm absolutely here for.
Nice serum with a clean, fresh scent that I appreciate first thing in the morning. My skin looks healthier and a bit more even after consistent use — exactly what I needed to add to my morning routine.
I have oily, combination skin and I was worried this might cause breakouts but my skin has behaved beautifully. Zero new congestion and my overall complexion is so much more balanced. The serum is genuinely a keeper.
Decent brightening serum that I've worked into my evening routine alongside my moisturiser. The dark mark on my chin from a stubborn spot has faded quite a bit, which I'm happy about. Good product overall.
I travel a lot and the compact size is actually perfect for my toiletry bag. My skin has been looking more even and less tired even when I'm sleep-deprived and moving between climates — this serum is doing serious heavy lifting.
I recommended this to my mum and she's as obsessed as I am. Both of us have noticed our skin looks more awake and the dryness around our cheekbones has reduced — I think the Vitamin E plays a big role there. Brilliant little product.
