The hype for 345 Relief Serum is real
I'm a skeptic with viral stuff, but 345 Relief Serum showed results in five days. Before-after pic and case closed.

Slotting Centella asiática into my routine was easy
I worried the Centella asiática would clash with what I already used — not at all: the 345 Relief Serum plays nicely with everything, no pilling and it sinks in fast.

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.

Great serum, ease into it
The first days I used 345 Relief Serum every other night to let my skin adjust. Now daily and my cheek texture is much finer.

Great value for the quality

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.
