4PM - xinyen review for Galactomyces Niacinamide Serum

4PM Galactomyces Niacinamide Serum 30ml Its texture is moist, it is rare in the serum. It is very easy to be pushed away and absorbed on the face, and it only takes about 30 seconds. It's a transparent texture.My own usage is already one pump at a time.I didn't feel any irritation or tingling when using it.It can help us improve the barrier function of skin and prevent water loss.I have been using it for a short time, and it seems that there is no whitening and brightening effect at present. But I would recommend this serum. Its price is very cheap and its texture is suitable for oily skin.
