Isola Niacinamide 20 Treatment

This is Isola's 20 percent niacinamide solution.

High-concentration niacinamide has excellent sebum-controlling capabilities, so those with oily skin

It's good to use. Actually, you don't even need up to 20 percent; using a 10 or 15 percent product is enough.

I think it is sufficient. I used to use a 10 percent product from another brand, but Esol's 20 percent

I have been using the product every other day, but it feels a bit irritating, so I plan to purchase Isola's 10 Percent product again once I finish this one.

Using a high concentration of niacinamide creates a skin condition that makes it difficult for blackheads or whiteheads to form. However, you need to regulate your intake to prevent your face from becoming too dry.
