Can I used this, good molecules discoloration serum, jiyu toner wipes together
- Asked by Kimah
- Official Answer By Good Molecules - Brand EngageYou can use the 5% Niacinamide Serum with Ectoin with the Jiyu toner pads, but I'm not sure the percentage of niacinamide in the Jiyu pads. Depending on the person too much niacinamide can be irritating to the skin. If you do notice irritation stop using them together.Was this answer helpful to you

Decent
I used this at a time where not much was working for my acne. I liked this serum but didnt see huge results. Turns out my main skin concern ended up being acne rosacea so that could've been the reason why. I used the whole bottle and it didn't irritate my enflamed skin so i think its pretty decent.
Second bottle and going strong
My skin has been loving this product my pores are visibly smaller and my skin is hydrated

Just not for me 🥲
I really wanted to like this serum but sadly my skin really wasn't a fan of it and it made me breakout in places i usually don't… So this product i wont be buying again < 3
Skin so Soft, Skin so Smooth, Pores so Invisible!
I have large pores on my nose, on my cheeks, and some even across my T-zone. Not super self-conscious about them but I am "hyper" aware of their existence. I use a standard bar cleanser and oil cleanse (when i wear makeup)—but still they are very obvious. Been using this for about 2 weeks and I can say I SEE the difference. Alongside a toner + mandelic acid serum, my skin has become so soft and my pores are LESS VISIBLE. Doesnt irrtate me. No redness. I use both in PM & AM (with sunscreen as recommended) 10/10 will order and recommend this to any large pore girlies.
