Overpriced but it works.
Size: 1.3 Fl Oz (Pack of 1)
I hate that I love this product. It's stupid expensive. But it's great for broken/damaged/recovering skin. I've used it post microneedling and it is the only thing that soothes, hydrates, and doesn't sting raw, red skin. Great for rashes/hives and allergic reactions too. Luckily a thin layer is often enough to do the trick. so it lasts a long time I wouldn't use for everyday moisture, but when your skin is angry, this stuff works. (Overpriced? Yes. Witchcraft? Maybe. Does it work? Yep.)

Nice!
For someone who doesn’t use tanning lotion (like me) this was a no brainer. I washed my hands after applying but applied just like normal lotion over elbows, knees and ankles. No orange spots. Subtle color but that’s the true trick !

This is pretty good. I noticed a golden glow right after I used it. It smells good and didn't transfer onto my clothes. You can apply it whenever you want. It fades easily of course after a shower, however, just reapply it! I used my hands and just rubbed my entire body. Didn't really streak where it's super noticeable, but I did have a few and no big deal really. Just add more. You definitely get a nice glow and the price is great especially compared to the more expensive lotions that I didn't like at all! The bottle is a nice size. I recommend this if you don't want to spend a lot and you'll definitely get a tinted glow!
