The hype for The Alpha is real
I'm a skeptic with viral stuff, but The Alpha showed results in five days. Before-after pic and case closed.

Light texture, potent results
The The Alpha is one of those that feels weightless but delivers. My skin was noticeably bouncier after a month.

Even my husband noticed The Alpha
And that deserves a Nobel. He said 'did you do something?'. Just The Alpha, two weeks.

Very good serum, needs a month
The Alpha works, but be patient. Four weeks in and my skin is more even and bright. Not overnight magic.

Great serum, ease into it
The first days I used The Alpha every other night to let my skin adjust. Now daily and my cheek texture is much finer.
