Après 2 mois d'utilisation je n'ai vue aucun changement positif, ma peau est plus sèche qu'avant.

I like this product. It smells nice but not overpowering. As stated in the title, it feels light, I like that it doesn't leave a "sticky" feeling on my face. In fact I don't feel it at all after. I also sometimes use it as a day cream

Burns the skin when you first put on, if you have sensitive skin

Blue Retinol is a nice soft firmer serum that slowly reduce the wrinkles in your face and take a good care of my skin

Little goes a long way. Absorbs quickly without leaving sticky residue. Skin feels hydrated after use. Pleasant scent.

Absolute game changer i'm seeing very fast results. The improvement is extremely impressive and fast! I'm 65 in October the lines around my mouth have diminished my 11s have diminished. And I have used retinol from aestheticians and this one takes the cake! I have sensitive skin and it is gentle and what I love about it as well as it's actually moisturizing it's absolutely perfection no burning sensation at all.

Generally love biotherm products, but that product should be used with caution; My skin is sensitive and I got a severe allergic reaction!!!!

Excellent product. Horrible packaging. The dropper provided is difficult to use, doesn't disburse the product well. I ended up simply tapping the jar to my palm and applying. Which results in having too much product.

this is the first time I've tried using Biotherm night serum. I've found this product to not cause my skin any issues at all thankfully
