amazing Items

COSRX The Alpha Arbutin 2% Discoloration Care Serum has almost no scent, very easy to use, and the quality feels lightweight but effective. The size is 20–30ml, practical for daily skincare, and the package with a dropper bottle is minimal and hygienic. Suitable for any age, it provides benefits such as brightening dark spots, evening skin tone, and improving overall radiance. The composition includes 2% alpha arbutin, niacinamide, and soothing bases, making it gentle and suitable for sensitive skin. Recommended frequency is morning and night, though possible concerns may include mild irritation if overused or when combined with other strong actives

I like the texture

I like the texture and the ingredients but after using the whole bottle, I don't see any changes. Maybe I buy again in case it needs more time.

Gentle powerhouse for daily use

This is a solid alternative to Vitamin C if your skin is too sensitive for L-Ascorbic Acid. I love the 50ml size; it’s much more generous than the typical 30ml serums. The combination of Alpha-Arbutin and Tranexamic Acid is a smart formula for stubborn post-acne marks (PIH). It feels very cooling and doesn't pill under makeup. No breakouts so far, and it feels high-quality. Perfect for those looking for a steady, non-aggressive brightening serum.

Decent serum

I noticed a little fade in my dark spots and softer skin I used for a couple months. I recommend it for light dark spots not for melasma.

I think it’s a good product for the skin, but I haven’t noticed any visible results on my face after using it for two months.
