I love this product so so much!! Honestly, I thought the comments were kinda exaggerating but, oh my, was I wrong. This is such a good serum. The fact that it’s fungal acne safe and non comedogenic??? And it literally has the rating 100/100 for me so props to the app/site.

This serum is a must-have for oily skin! It's extremely effective, especially when used in the morning plus at night. I've noticed a big reduction in sebum production on my skin, as well as a slight effectiveness on redness and marks. However, it's not very effective on active blemishes, and mainly helps to limit their future appearance. On the plus side, it's quite moisturizing.

I got a sample of this and saw that it was FA safe and had no comedogenic or irritating ingredients so I tried it out. Only used it 4 times, but it was pretty obvious what a powerful humectant beta-glucan is. Just pure hydration and calm. Definitely buying the full size if I need the extra hydration. In this regard, it beats the skin1004 madagascar centella ampoule! (Still love that for beneficial Show more

Very hydrating, my must have product
Wow. I regret not buying this earlier. It's a somewhat thick serum that's very moisturizing and absorbs nicely into the skin,depending how much you use. I go heavy on this and put a full dropper on my face and it takes a while but it does sink in.

It has helped with my rosacea flareups and dry patches.

It's niacinamide free so it's a great hydrating Show more
