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!

Self Tan Remover
Worked well. My granddaughter was looking orange from self tan lotion she used and removed it easily.

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.
