Cleared scaring and imperfections

Literally LOVE! After a long and rough period of anxiety popping/picking at my face I was left feeling even more anxious at the sight and state of my skin. I have tired so many products from budget friendly to extremely expensive and it either didn't work or my face would break out. I was so sceptical because I had literally lost all hope in finding the perfect product… but here I am three weeks using this serum and loving it.

Not recommend

Bought this one together with the EFFCLAR DUO Moisturiser to try to fix my blemish prone skin. It doesn't work very well and makes my skin sensitive with small red dots.

Love it!

This stuff is amazing. I get large under the skin cystic acne and a dab of this and in a couple of days it's gone! I highly recommend this and the whole brand. I have very sensitive skin and this stuff is very gentle.
