moisturizing
I was curious about this product since I saw it very viral on tiktok recommended by an influencer (Nina Pool) so I bought it, since it is small, I said: if I don't like it at least I didn't spend a lot. The truth is my skin is dry and I didn't think it would really work, and I can say that for being the first time that I let myself be carried away by those tiktok recommendations I loved it, mainly the milky toner I use it after washing my face and it leaves it very soft and when I go to put on foundation I combine it and it is incredible. I recommend it 100%

Best for nighttime skincare
These worked so well for me. I have extremely sensitive dry skin and I break out from most products. I use these 2 every night after the cerave hydrating facial cleanser, and then I use the embryolisse moisturizer to lock it all in. My skin is smooth and hydrated. I get told all the time that i have baby skin. I'm 25 years old.
