Derma Factory Niacinamide 20% Serum

I recommend a serum that is a must-have in your daily skincare routine!

It is the Derma Factory Niacinamide 20% Serum.

Niacinamide has various benefits, including whitening, strengthening the skin barrier, and improving sebum control!

I have tried niacinamide products from various brands, and I found Derma Factory's to be the most cost-effective, and I think it would be easy for beginners to use.

When using niacinamide for the first time, it can irritate the skin, so those with sensitive skin types should definitely test it first.

I felt that this product was gentle despite its high concentration. The moisturizing power is also good, so I think even those with dry skin would be able to use it well!

Unfortunately, I didn't notice a significant whitening effect. However, I did feel my complexion becoming clearer overall, and best of all, it has absolutely no downsides! If you aren't expecting dramatic results, it's a decent product to use, so I recommend it to beginners.
