Tiam Vitamin C 24 Surprise Serum | KoreanShopBD

At 22%, this is a genuinely high-dose vitamin C serum that produces faster and more visible results on dark spots, post-acne marks, and uneven skin tone than the 10% to 15% concentrations used in most vitamin C serums sold in Bangladesh. The 2% vitamin derivative complex — including vitamin C and E derivatives — extends the antioxidant coverage and supports the primary ascorbic acid for a more comprehensive brightening and protective effect. For skin in Bangladesh exposed to intense daily UV radiation and urban pollution, a stable high-strength vitamin C serum is one of the most impactful daily treatments available.
