WishCare Vitamin C16 Serum — pigment production runs through an enzyme called tyrosinase, and the most effective brightening formulas interrupt it at more than one point rather than relying on a single ingredient.
This one pairs 10% boosted vitamin C with 1% kojic acid — two tyrosinase inhibitors that work by different routes, plus vitamin C’s antioxidant effect on daily sun and pollution damage.
Best for
Dark spots, post-blemish marks, uneven tone and dullness.
How to use WishCare Bright Vitamin Serum
Apply in the morning to clean skin, before moisturiser and sunscreen.
Worth knowing
Vitamin C oxidises with light and air. Keep the bottle closed and out of the sun; deep yellowing means it has lost potency. Sunscreen is not optional with any brightening product.
What is in it
Vitamin C
Vitamin C does two useful things at once: it interferes with the enzyme that produces pigment, and it neutralises some of the free radical damage that daylight causes. That makes it a morning ingredient — it works with sunscreen rather than replacing it. Pure L-ascorbic acid is the most studied form and also the most temperamental, oxidising when exposed to light and air. A darkening bottle is a real signal, not a cosmetic one. Background reading on vitamin C if you want the chemistry behind it.
Kojic acid
Kojic acid is a by-product of fermentation — it was first isolated from the mould used to make sake — and it inhibits tyrosinase, the enzyme that starts pigment production. That places it in the same family of action as arbutin and vitamin C, and it is frequently paired with them because the combination covers more of the pathway than any one of them alone. It can irritate at higher concentrations, so introduce it gradually.
What to use it with
Seal this in with a moisturiser and apply it to skin that is still damp from a toner — both steps make a measurable difference to how much of the serum stays where you put it. From the rest of our range, APLB Tranexamic Acid Niacinamide Facial Cream and Acwell Licorice pH Balancing Cleansing Toner are sensible companions, and both are stocked with the same cash-on-delivery terms.
Where it fits in your routine
A serum goes on after cleansing and toning, while skin is still slightly damp, and before anything heavier. That order matters more than people expect — the thinnest, most concentrated layer needs direct contact with skin, not a film of moisturiser in the way. Give it thirty seconds to absorb, then seal it in with a cream. If you are using more than one serum, the lighter one goes first.
Before you start
Keep this away from light and heat, and close it properly. Vitamin C oxidises with exposure — if the liquid turns deep yellow or brown, it has lost most of its potency and is worth replacing.
Common questions
Is WishCare Vitamin C16 Serum authentic?
Yes. Euros Belle stocks sealed, unopened units sourced through the brand’s own distribution, and we do not sell testers, decants or refilled packaging. Every order is checked before it leaves us, and you are welcome to inspect the seal at the door before paying.
Can I pay cash on delivery?
Cash on delivery is the only payment method we offer — there is nothing to pay in advance and no card details to enter anywhere. You pay the delivery agent when the parcel reaches you. Inside Dhaka delivery is ৳70 and takes one to two days; outside Dhaka it is ৳130 and takes three to four.
What size is WishCare Vitamin C16 Serum?
This listing is the 30 ml size, priced at ৳1,299. Where a product is available in more than one size, each is listed separately so the price you see is the price for the size shown.
How long before I see a difference?
Longer than most marketing suggests. Pigment and firmness respond over eight to twelve weeks of consistent use, not days, and stopping and restarting resets that clock. Hydration and comfort improve much sooner — often within the first week.
