Real glow in two weeks
Two weeks with 345 Relief 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.

You really can feel the Ácido hialurónico
It's not marketing: the Ácido hialurónico in the 345 Relief Serum shows in my skin texture from week one. The Pantenol balances the formula and gave me no reaction. Dr. Althea nailed this one.

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

Good but not for me
The 345 Relief Serum 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.
