I bought it for the Ácido tranexámico (TXA) and it delivered
I read the ingredient list before ordering and the Ácido tranexámico (TXA) was exactly what I wanted (with Glutatión alongside, even better). Three weeks with the No.5 Glutathione TXA Advanced and my skin looks more even and comfortable.

Light texture, potent results
The No.5 Glutathione TXA Advanced is one of those that feels weightless but delivers. My skin was noticeably bouncier after a month.

The dropper gives exactly the right amount
Three drops of No.5 Glutathione TXA Advanced cover face and neck. Six weeks in my skin feels firmer and the Complejo iluminador has given me zero issues.

Even my husband noticed No.5 Glutathione TXA Advanced
And that deserves a Nobel. He said 'did you do something?'. Just No.5 Glutathione TXA Advanced, two weeks.

Great serum, ease into it
The first days I used No.5 Glutathione TXA Advanced every other night to let my skin adjust. Now daily and my cheek texture is much finer.

Good but not for me
The No.5 Glutathione TXA Advanced didn't irritate me, but I didn't see the change I hoped for in a month. Might need longer, but I'll move on.
