Why vitamin C is worth it in Bangladesh
Vitamin C is the single most useful "glow" active for Bangladeshi skin: it fades the dark spots and post-acne marks our climate and sun make worse, evens out dullness, and adds antioxidant protection on top of your sunscreen. But it is also the active most often sold fake or oxidised here — a browned, orange serum has already gone off and will do nothing. Buy it verified.

How to choose a vitamin C serum
- Form matters more than the number. L-ascorbic acid (LAA) 10–20% is the most-studied but oxidises fastest. Derivatives (SAP, ethyl ascorbic acid, ascorbyl glucoside) are gentler and far more stable in our heat — better for beginners and sensitive skin.
- Start at 10%, not 20%. Higher is not better if it stings.
- Packaging: opaque or dark glass with a dropper or pump. Clear bottles let light oxidise the vitamin C.
- Colour test: a fresh serum is clear to pale yellow. Deep orange or brown = oxidised, throw it out.
- Always pair with sunscreen the next morning — see the best sunscreen guide.

How to use it without irritation

Common vitamin C mistakes here
- Buying an already-oxidised (orange/brown) serum — a classic sign of old or fake stock.
- Skipping sunscreen — vitamin C without SPF undoes its own work on dark spots.
- Going straight to 20%+ and quitting when it stings.
- Storing it on a sunny windowsill — heat and light kill it faster in Bangladesh.

Before you buy: check authenticity, not price
Don’t chase the cheapest product — look for the authentic one. A cheap fake can damage your skin, and using nothing at all does less harm than using a counterfeit. But a high price doesn’t guarantee authenticity either — people overpay for fakes too. So judge by authenticity, not price.
TheSkinProof offers free authenticity verification. Message our Facebook page with the product and we’ll analyze it and tell you whether it’s real or fake — so it’s important to verify before you buy anything. Or simply buy from TheSkinProof, where every product is already invoice-verified with a 2× money-back guarantee.
