Product Summary
"Cos De BAHA - Buy Cos De BAHA TN Tranexamic Acid Niacinamide Serum Australia - Korean Skin Care and Cosmetics" is effective for: Evens skin tone, Anti-blemish, Anti-aging and Moisturizing
Ingredient callouts
- A good concentration of Niacinamide (4.80% - 7.20%). Niacinamide is a well-studied multi-tasking active. It is stable, and can work well in almost any hydrating formulation. There is solid evidence that Niacinamide can help support skin barrier, regulate oil production and reduce acne and clogged pores. It also helps to fight photodamage and improve the skin tone, reducing pigmentation marks.
- In addition, this product contains Allantoin (1.00% - 1.50%). Allantoin is helpful in wound-healing and can help restore the skin barrier faster. It might also be able to improve scars, but the evidence is not very strong for this.
- Humectants (allantoin 1.00% - 1.50%, sodium hyaluronate 1.40% - 2.10% and betaine 2.90% - 4.40%). These ingredients help attract water to the upper layer of the skin and improve the skin hydration.

Anti-aging
This product can help reduce and prevent fine lines and wrinkles, improve skin elasticity and firmness because it contains niacinamide.
Keep in mind that it typically takes at least 6 weeks to notice any results because the changes that are needed to improve fine lines and elasticity happen in the deeper layers of the skin. No topical anti-aging product can “erase” wrinkles or fully reverse signs of aging.
Is proven to be effective in reducing blemishes, evening out skin tone and helping to improve lines and wrinkles. It helps the skin to repair sun damage, calm down inflammation and keep maintain good levels of moisture. The concentration of about 2% is effective for supporting the skin barrier and evening out the skin tone. Concentration of 4-6% is better for helping with acne and balancing the sebum production
Can contain potent anti-oxidant compounds (abbreviated ECG, GCG, EGC, and EGCG) that might help protect the skin from free radicals. Can help calm down inflammation and has some anti-bacterial properties. Unfortunately, these antioxidants are unstable and lose their effectiveness very quickly in products. The concentration of the antioxidant compounds in the extract also tends to be low to be effective in topical formulation

Moisturizing
This product contains good ingredients to attract water to the upper layer of the skin. These ingredients are called "humectants": allantoin, betaine.
When humectants are on the surface of the skin, they “pull in” the moisture from the outside environment, or from within deeper layers of the skin. If the air is dry, humectants can speed up the moisture loss from the skin. This is why it is a good idea to use another product on top of this one to help "seal in" the moisture (look for ingredients like dimethicone, squalane, oils and butters).
The following ingredients in this product are especially good for supporting the skin barrier and helping with the hydration level: niacinamide
