You feel the Prebióticos in Dual Barrier Boosting Serum
High potency, no irritation. Dual Barrier Boosting Serum sinks in like water and after two weeks you can see the brightness.

You really can feel the Prebióticos
It's not marketing: the Prebióticos in the Dual Barrier Boosting Serum shows in my skin texture from week one. The Extracto de centella asiática balances the formula and gave me no reaction. Celimax nailed this one.

Real glow in two weeks
Two weeks with Dual Barrier Boosting Serum and my skin already looks brighter and more even. It doesn't sting or feel greasy, even on my sensitive skin. Plus it arrived home in under 24 hours.

Even my husband noticed Dual Barrier Boosting Serum
And that deserves a Nobel. He said 'did you do something?'. Just Dual Barrier Boosting Serum, two weeks.

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