Serum Twenty

Nice serum for this weather in Phoenix, feels lush and that my skin absorbed it nicely. I have tried samples in the past and they seem to have added a bit of plumpness which is really nice on 49 year old skin : )

The BEST Vit C serum you will get!!

This is honestly the ONLY effective Vit C serum I have used, it reduced my dark spots from acne and skin pigmentation! Been using this for a month and already see amazing results plus haven’t had any new breakouts!! My face looks a lot brighter and radiant, worth the try you will not regret it!!

It really worth it, I will buy it again and again

Conocí la marca y el producto gracias a una muestra por parte de mi cosmetóloga (en Puebla, Mexico) y de verdad me enamoré después de 10 días de uso!! Realmente vez mejoría en tu piel, la perfecciona y mantiene lisa. Las manchas como tal no las quita pero si disminuye el tono y con 3 gotas máximo 4 es suficiente para todo el rostro. Lo recomiendo ampliamente!
