Geek & Gorgeous - SkinHarmony90 review for B-Bomb

I have been using it for a long time, although the result for acne from niacinamide (vitamin b3) can be seen after 8 weeks somewhere, and for hyperpigmentation after 4 weeks. With their 10% concentrate, zinc PCA and sarcosine formula help with past enlarged pores, oily nose and blemishes. • It is my first niacinamide serum and it gives me pleasure, because it really lightens my acne scars, I do not have any blackness, and I am prone. Now I combine it with azelaic acid and it is good for now. I combined it with the salicylic from Revox, but something did not leave an impression on me of this combo, and I think that the problem was with the salicylic because I used it myself and that's why I know. • Combinations that can be used niacinamide: with all but vitamin c (it is better when the composition of the product contains these two ingredients) and with aha acids. Combo examples with niacinamide: + salicylic acid - for acne + azelaic acid - brightening + retinoids - reduces the risk of irritation caused by retinol. + mandelic acid - soothes redness • Cruelty free, no gluten, no fragrance and essential oils, pregnancy safe.
