If you’re worried about dark skin and the side effects of hydroquinone, AN Serum from Cos De BAHA is the answer.
 
Arbutin is a plant-based compound that resembles synthetic hydroquinone but has a skin whitening effect with no side effects or risks, making arbutin safe and effective for people with sensitive and uneven skin tones.
 
MEDICAL RESEARCH HAS PROVEN that arbutin is very effective in treating pigmentations, age spots and it can also inhibit the negative effects of UV-radiation thanks to its sun protection properties. Arbutin evens out skin tone and is also effective in treating acne scars.
 
Arbutin can also be combined with other skincare ingredients to maximize its efficacy, for example, with an alpha-hydroxy acid (AHA) to exfoliate skin and facilitate its absorption of arbutin. When paired with Vitamin C, arbutin imparts even skin tone with improved radiance.
 
How to use:

• Generally – After cleansing and toning your face. Apply 1~2 drops of serum at night and day. Do not wash or wipe after applying the serum. After applying this serum, we recommend using a skin moisturizer. Massage a small amount of cleanser to wet skin, avoiding eye area.
• Sensitive – Is your skin sensitive? Please mix with other Pure Serum. If your skin has fully adapted to the ingredients, you can expect faster results with only the product in question. Or use our 5% niacinamide toner first.

 
Do you use it for the first time?
Please note that all serums can sometimes create irritations for people with very sensitive skin or uncommon allergies. Always test the product on a small area before using it, ideally behind an ear or under the chin. Allow 24 hours to measure skin sensitivity to the product.
