No pilling under sunscreen
That was always my issue. The 6 Peptide Skin absorbs completely and I can layer SPF and foundation with nothing balling up.

Slotting Alantoína into my routine was easy
I worried the Alantoína would clash with what I already used — not at all: the The 6 Peptide Skin plays nicely with everything, no pilling and it sinks in fast. The Hialuronato de sodio adds to it without weighing the formula down.

Light texture, potent results
The The 6 Peptide Skin is one of those that feels weightless but delivers. My skin was noticeably bouncier after a month.

You feel the Hialuronato de sodio in The 6 Peptide Skin
High potency, no irritation. The 6 Peptide Skin sinks in like water and after two weeks you can see the brightness.

Very good serum, needs a month
The 6 Peptide Skin works, but be patient. Four weeks in and my skin is more even and bright. Not overnight magic.

Didn't do what I hoped
A month with The 6 Peptide Skin and my skin is the same. Guess I need something else.
