COS DE BAHA NZ Niacinamide 20% Serum Niacinamide High Blend Pore Tightening Elastic Care Korean Cosmetics (Official Japanese Product) NZ 30ml

I can fill the change after 2 days use. After using 2 weeks my skin looks brighter and healthier. I just love it

My pores are getting smaller, its my 3rd bought now. I'm happy to the result. I will buy again. Niacinamide is good for the pores.

I just started using this product and I can't see the effect yet. In general, I love this brand's products, they are usually very effective. But this serum is very thick and sticky. It cannot be used during the day, only at night

I love noacinamide and this particular product! Haven’t found any other brand in Japan offering 20% niacinamide serum (although for beginners I would say better is 10%). Skin is tighter and firmer, with no excessive sebum.

Good

Formulation is good and it is lightweight on the skin

OK

特に目の下の小じわが極端に減りました。ちょっと自分でもびっくりです。保湿がいいのかナイアシンがいいのかわかりませんが、ベストを尽くすことに意味があるので改善されていればよきです。ぬるっとしてますがアロエのようです。
