My new Holy Grail product!
This is INCREDIBLE! Ok, firstly, let me say that I apply it after shaving and razor burn is a distant memory now. It has also taken down the drastic redness and red marks that previous shaving had left my skin w. My skin is smoother and softer now.. including my bikini area. Not to be tmi but, I have a c section scar, it’s nearly impossible to prevent ingrown hairs in that area bc of the scar tissue .. or so I thought! OMG , I’ll never give this stuff up ! It also helps w my back acne and is easy as pie to apply , doesn’t smell weird and absorbs nicely .. bonus points.. it will tame the zits on your bum too .. but wait .. there’s more ! My super pale sensitive skin on my legs has been forever marked w scars from shaving and always has little red marks besides that so I’ve always been insecure about my legs even though they’re long and strong .. dude .. I kid you not, this has been taking the red marks out and no more razor burns.. or bumps plus all of the scars are starting to fade !! This is a HOLY GRAIL PRODUCT! I had literally quit shaving my legs before this and now.. I’m feeling so much better about it & myself and omg thank you for this product! Never ever stop making it !

Decent Product
Ok so I would take this review with a grain of salt because I feel like the results of this product really just depends on how and when you use it. I received my peach slices roller after I already shaved so I’ve been using it as my hair is growing back. And what I can say is … it doesn’t make the ingrowns and all the marks go away, but it definitely makes them appear lighter and they’re not as prominent. However, if I had used this either before or during shaving, I might have gotten a different result. So , as far as it being effective, it’s really the difference between preventing the ingrown and then making them go away. but it’s very smooth and easy to use has a pretty neutral smell.

Staple item!
Seriously so thankful I found this Peach Slices ingrown hair product. I’ve struggled with bumps and irritation for so long, especially after shaving, and this has made such a noticeable difference. My skin feels smoother, less irritated, and the ingrown hairs have improved so much with consistent use. It’s gentle, easy to apply, and doesn’t leave my skin feeling sticky or overly dry. Definitely one of those products I’ll keep repurchasing!

NEW HOLY GRAIL OF SKINCARE
Peach slices is now apart of my regular shaving routine. It got rid of old stubborn ingrowns after every hack in the book. Then it prevents new ones from forming. I’ve been using it for months. It has no smell so fragrance free. It’s also very moisturizing. The consistency is almost like a thinner aloe Vera. If it works my sensitive skin than I’m sure it would work for most skin types

Cleans and deodorizes better than others
Scent: Assorted, Size: 10 Count (Pack of 6)
This is the only thing that seems to really remove odors from my garbage disposal. So glad I was able to find it again. Highly recommend it.
