Absorbs your lotion
Pattern Name: 1 Tanning Mitt
Protects your hand and the application is smooth... BUT it absorbs SO MUCH PRODUCT!!! Like waists so much of your tanning lotion. I decided to stop using it and just wash my hands right after applying bc it isn’t worth how much lotion gets absorbed into the mitt & goes to waist.

Must have tanning mitt for easy and even self tanning!
Pattern Name: 1 Tanning Mitt, Pattern Name: 1 Tanning Mitt
If you use self tanner you NEED this mitt! The foam tanner came on so much easier and it's so much nicer having this mitt to apply product rather than trying to use gloves or just bare hands!
It applied so much more evenly and was very easy to use. It keeps your hands from getting stained and it's very easy to clean and use over and over.
This is my first mitt for tanning and as far as I'm concerned it will be my last... its perfect...feels like velvet and applies a perfectly even coat of the lotion.
It is also double sided and VERY soft. And two smaller ones that are great for smaller areas. So great for the price too. My tan looks so even and I have already gotten so many compliments. I am LOVING my glow.
Highly recommend!

A gentle miracle for my skin!
I've been using this product for about a month now, and I'm honestly so impressed. I have acne-prone and sensitive skin, and this Ordinary product for oily skin has made a significant difference.
From the very first week, I noticed my skin was softer. It’s lightweight, absorbs quickly, and doesn’t feel greasy at all. I use the Squalane cleaner both in the morning and evening. In the evening, I use natural moisturizer and B5 after washing my face.
What I love most is that it’s affordable but delivers real results. No fragrance, no irritation—just effective skincare. I’ve already recommended it to my friends and will definitely repurchase.
