Reliable!
Pattern Name: 1 Tanning Mitt
I don't normally use self-tanner, but having a mitt does make me more likely to, since it makes the process a little easier and cleaner. Very easy to use, I like the sleek black design with a loop to hang it from hooks to avoid mess! I've been testing this out for a couple weeks now and it's held up considerably well; the material hasn't lost its shape or taken any ugly creases. Washing is a breeze in the sink - I haven't tried in the washing machine yet, but I feel like it'd hold up. The mitt is not too thick, not too thin, product goes on smooth and even given that the material does the same with your self tanner that, say, a beauty blender would do with your foundation - it soaks up a little bit of product to make sure the overall application goes a long way, and keeps the whole surface looking smooth and even.

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.
