Tranexamic Acid Serum

Serenvit Tranexamic Acid Serum is BIOSAR's targeted serum for stubborn discoloration. Tranexamic Acid evens long-standing dark areas; Niacinamide regulates the underlying drivers of uneven tone; Vitamin C brightens for faster visible response. Use it morning and night for melasma, post-inflammatory hyperpigmentation, and uneven tone that has resisted basic brightening routines. Always pair with a daily SPF30+. Pigmentation will rebound without sun protection. Suitable for adults; tolerance-tested under dermatological supervision. Pairs with the Serenvit Vitamin Complex Serum and any Whitepurity product.

Why it works

Stubborn dark spots meet their match. Tranexamic Acid and high-strength Niacinamide work two pathways at once to fade discoloration and even tone, while Zinc PCA balances and refines on a soothing Aloe Vera base. Marks look lighter, tone looks more uniform, and skin looks clearer and more luminous with consistent use.

How this formula works

The drop that fades the memory of old marks toward even tone

Tranexamic Acid targets the look of stubborn marks and uneven patches, and Niacinamide joins in to even out overall tone and clarity. Zinc PCA and the Aloe Vera base keep the skin balanced and calm as the two brightening actives do their work. Rather than chasing one dark spot, this drop reads as a complete tone-correcting step that lets skin look clearer and more uniform.
