Moisturizing
Easy to apply, does not feel greasy. Used on legs after shaving. Did not clog pores. Legs felt smooth and moisturized

Got a rash from it
Color: Green, Size: 2 Fl Oz (Pack of 1)
I'm in that percentage of women who have chin hair, unfortunately. I shave almost every day so I bought this thinking maybe it would help stretch it out a few days. I used it twice and broke out in a rash (just on the chin/neck area). I was sitting at work and subtley scratched my chin area. Thought nothing of it. Then I scratched a little more. Until I realized something wasn't right. By the time I got home I could see the red. My skin can sometimes be sensitive to new cleansers/creams/oils. It may work for some, but it didn't work for me. On a positive note, it's odorless, lol.

Great after shave product for smooth skin

Not only does it help slow hair regrowth, it helps with razor burn too!

PLEASE MAKE A BIGGER SIZE, NEVER STOP MAKING THIS ‼️
I purchased this a few months ago back in November 2025 because of all the TikTok hype. It's now June 2026, and even though it's only 50ml, it lasts SO long. A little goes a very long way, and I still haven't finished it yet!!
I originally bought this to use after waxing my underarms because I'd always get painful bumps, irritation, itching, and overall discomfort. I'd only apply it at night, and by the next day the bumps and irritation had gone down significantly! Whenever I get bumps, irritation, or discomfort, I use it for about 3 days to a week and it works so fast 😍
I really wish they sold a bigger size because the reviews are not lying💯...this thing works wondersss. It's worth every single dollar. It's also pretty good at targeting ingrown hairs too. Like omg, it's basically a painkiller in a bottle 😂 It has saved the day so many times & I've used this quite a lot, lol.

Charming Roll-On Power
I've had a difficult time with shaving with sensitive skin. I can use multiple different types of razors, lotions and creams. It doesn't always work well for me. So I saw this mentioned on TikTok and I thought I would give it a go. I'm impressed by how good it calms any irritation or itchiness I may have. It applies on cool and and it's easy to use. It carries no scent. It's a small roll-on and lightweight. It's soothing and moisturizing to the irritated skin. Works like a charm. Would recommend!
