## Description

Cos De BAHA Tranexamic Acid 10% Facial Serum (TT30) is a focused cosmetic serum created to improve the look of dark spots, uneven tone, and surface discoloration while helping the skin feel comfortably hydrated. This formula combines a high level of Tranexamic Acid with Niacinamide, EGCG (Epigallocatechin Gallate), and Glutathione to support a more uniform and clear-looking complexion over time.The serum uses Centella Asiatica Extract and Aloe Barbadensis Leaf Extract as a calming base, supported by Butylene Glycol and Glycerin to provide light, everyday moisture. Tranexamic Acid and Niacinamide work together to reduce the appearance of patchy, uneven-looking areas, while EGCG from Green Tea, Glutathione, and Tocopheryl Acetate offer antioxidant support for skin that looks smoother and more refined.Panthenol, Allantoin, Dipotassium Glycyrrhizate, and Madecassoside help maintain a comfortable feel, making this serum suitable for regular cosmetic use, especially on skin that looks easily stressed. Sodium Hyaluronate offers an additional layer of hydration, and a blend of emollients (Cetearyl Olivate, Sorbitan Olivate, Cetearyl Alcohol, Caprylic/Capric Triglyceride, Dimethicone) gives the formula a silky, lotion-like texture that glides smoothly and absorbs without a heavy or greasy finish.Botanical extracts including Camellia Sinensis Leaf, Sambucus Nigra Flower, Momordica Charantia Fruit, and Leontopodium Alpinum complement the overall formula with plant-derived cosmetic benefits. With consistent use in a balanced skincare routine, skin can appear more even, clear, and polished in overall tone and texture. This product is a cosmetic serum and does not claim to diagnose, treat, cure, or prevent any disease or medical condition.How to Use After cleansing and toning, apply 1–2 pumps of the serum evenly over the face, concentrating on areas where uneven tone and visible dark spots are most noticeable. Gently massage or pat until fully absorbed, then follow with your preferred moisturizer. When used in the daytime, always finish with a broad-spectrum sunscreen as the last step of your routine. If you are new to this type of active serum, begin with once daily or every other day use and adjust frequency according to your skin’s tolerance.Storage Store in a cool, dry place away from direct sunlight and excessive heat. Keep the bottle tightly closed after each use and avoid touching the opening directly to the skin to help maintain product quality.Full Ingredient List (INCI) Centella Asiatica Extract, Tranexamic Acid, Butylene Glycol, Glycerin, Niacinamide, Isononyl Isononanoate, 1,2-Hexanediol, Aloe Barbadensis Leaf Extract, Panthenol, Allantoin, Dipotassium Glycyrrhizate, Sodium Hyaluronate, Tocopheryl Acetate, Camellia Sinensis Leaf Extract, Sambucus Nigra Flower Extract, Momordica Charantia Fruit Extract, Leontopodium Alpinum Extract, Epigallocatechin Gallate, Glutathione, Madecassoside, Cetearyl Olivate, Sorbitan Olivate, Cetearyl Alcohol, Caprylic/Capric Triglyceride, Caprylyl Glycol, Tropolone, Dimethicone, Carbomer, Xanthan Gum, Tromethamine.Product Specifications - Product Type: Facial serum (cosmetic) - Size: 30 ml / 1.0 fl oz - Key Highlights: Tranexamic Acid 10%, Niacinamide, EGCG, Glutathione, Centella & Sodium Hyaluronate - Texture: Lightweight, silky, lotion-like serum - Skin Type: Normal, combination, and dry skin concerned with dark spots, uneven-looking tone, and lack of clarity - Use: External use only; cosmetic product with no medical, therapeutic, or disease-related claims.

Review: Love it! - Great serum. I’d prefer a droplet bottle. I did find the serum dries on the tip of the pump if you don’t use it everyday and dries gritty. But if you pump it, it’s a smooth serum.
Review: Best TA yet! - This and the azeliac acid is the HG! I use this in am and the AA in pm. They are great combos to reduce age spots.

### ⭐⭐⭐⭐⭐ Great product
*by P***V on May 15, 2024*

This is thick white substance unlike their other trx/niacinamide 5/5% which I loved. Not sure how this product works but will definitely update. I sing praises of this brand typically. Update ** Working well
