A good product!

I have been using niacinamide for a while, I can’t fault the product, I can’t say it has made a massive difference to my skin personally but I do not get oily skin and I do not have acne prone skin so I think this works wonders for those with targeted concerns, I have enlarged pores though around my nose and cheek area and I have noticed a slightly improvement with them!

LOVE IT

Noticed improvement after a few days. Cannot use with Gycolic Acid toner as the combination makes my skin tingle.

Thank you for your feedback Linda! we're so happy to hear you are enjoying the product. Just a reminder that its not advisable to layer Niacinamide with Glycolic Acid as this can lead to irritation which could explain the skin tingling feeling you are mentioning!

Better skin

Less breakouts, better skin texture with less oil and shine through the day.
