Mine came with the lotion, applicator mitt, and a facial can mist. I haven't used the facial mist yet but here are my observations for the lotion: PROS - finish color looked very natural. Not orange at all. - no streaks / dark patches / missed spots (of course this has to do with the application as much as the product) - can build darker tan with multiple applications - did not transfer onto my clothing - the "self-tan lotion"scent was present but not terrible CONS - slight self tanner smell - made my scars look darker (not a product defect, my scars get darker from the sun too. Just mentioning in case someone has severe scarring /discoloration/ vitiligo to be mindful. First application I would say do full body. And maybe afterward learn to work around your darker skin spots. I didn't use the mitt for application, but it's nice and soft and comfortable. I used disposable cheapy medical gloves because I felt like I may not get good enough control and might leave streaks with the mitt. (With practice though, I will definitely use it because it feels nice and soft.)

Works great

Color: Medium Glow

This works great and darkens skin to a beautiful light tan but does somewhat wash off the next day so it does require reapplying the next day. I would purchase this again.

A good starter kit

A really good starter kit, the tan isn’t orangey and applies pretty easily. It doesn’t get super dark. The lotion is good to make the tan last longer but wash your hands really well or they’ll have dark splotches. The spray isn’t amazing and can look streaky

Works good

Color: Medium Glow

It smells like tropical scent after putting it on. The smell lingers for about an hour or two. It is not bad though, I like it- reminds me of summer scent. Instant tan works very quick. I am very fair I see no sun so, I put two layers on yesterday and two layers on today. I am significantly tanner. I only use my hands to spread it in, it would work better with less streaks if using a tool to help spread the product evenly. It leaves my skin feeling very smooth and hydrated and I like the color and scent, I like how it has hydrolaunic acid and vitamin c. Works good and stays on. I was able to convince my husband it was good to have because of the hydrolaunic acid and the vitamin c, I said it's a 3-in-1! I also bought this during black Friday week so, got it for a good price.

Quick drying, non sticky lotion!

Color: Medium Glow

Great even color and dries immediately. This formula is not sticky at all. The color may not be as dark as the gel or foam, but is very natural.
