Doesn’t take all the fan off. Leaves blotchy
Doesn’t get the tan off all the way and I’ve used it 4 times now. It makes the tan blotchy and uneven (yes I know that’s what happens when the tan is going away but like I said I’ve used it 4 times and it hasn’t made much difference. A regular exfoliant works better) I used the same brand tanner as well so not sure why it’s not working. Bummed tho!

What a find!
Color: PDRN 25%
Good stuff! My skin healed ULTRA fast with this!! I can really tell it is good stuff! Plus, it has that “bio” smell that means it’s real. The formula is a little oily as opposed to watery. Just FYI I think serum slightly thicker is better.
