Derma Factory Niacinamide 20% Serum

I paid for it myself

This is Derma Factory's Niacinamide 20% Serum.

It is said that niacinamide provides whitening effects by blocking the migration of melanin pigment.

It's also moisturizing.

There are many cases where cosmetics are sold at a high price as whitening products, but actually contain very little of the ingredients.

I purchased this serum because it contains a high concentration of 20%, so I thought it would be effective if I used it consistently.

I like the good absorption and the non-sticky texture.
