Anyone use with tretinoin? If so, which goes on first?

Can actually mix them, but if used separately, use niacinamide first. My mom is the actual user and researched the question. She did not derive any benefit from using niacinamide for discoloration. She naturally has no wrinkles and no one believes her age. She appears decades younger.

Can u use this on the derma microsculpt device?

No idea. I used it on my face as a moisturizer.

Relación calidad/precio excepcional

Hidrata y equilibra, reduce imperfecciones y aclara manchas, aunque no las quita. Relación calidad/precio excelente.

A must try!

I was skeptical, especially after seeing the viscosity of this serum. It seems pretty thick, and I thought it would be too sticky. But lo and behold, it was NOT too sticky, and it absorbed quickly. As far as the effectiveness, I'd give it high marks. It immediately brightened my skin, and made it feel suuuuper soft. It worked well under primer and foundation, as well as on bare skin. I used it on my face and the backs of my hands. Skin texture improved on the first few uses. Definitely worth a try. It's effective and very affordable. I absolutely love this stuff.
