Most definitely...I have sensitive skin!

i wear sunscreen everyday because i am on the lighter side. i apply the self tanner at night after i shower. that way i can chill out and let it dry before i put pajamas on. i put sunscreen on in the morning before i go out. i haven't had any problems using them together. i would not recommend using them at the same time. i would suggest self tanning, letting that dry and then using sunscreen. that way everything absorbs on it's own. good luck and cheers for the sunscreen, it's so very important!

I mix the bronzer and moisturizer for a natural look

I am sure that overtime yes it will as with all self tanners. Just like if you go to the gym, it will wear off in the spots faster where you sweat more. . Just do your normal activities and do not rub down with the towel instead just lightly go over to dry off. Advice:

Water will accelerate the fading of a sunless tan. In most cases, you shouldn't go swimming for several hours after applying the tanning product. This will allow time for the color to set, so it's not washed away by water. Wait for at least four hours before jumping into the pool. Some products recommend waiting up to eight hours. When in doubt, choose the longest period of time as your guide.

I don't have to moisturize with this product. I just put it on first thing in the morning, with or without makeup. If I'm wearing makeup, I use the self tanner as my moisturizer and just apply my foundation on top of it. It works great for me. It's nice because you can wear this self tanner without makeup. It gives you an instant subtle glow....nothing too drastic like other products. I use it every day. The more you use it, the deeper the color/tan gets.

I have already used it about 5 times and i have more than a half a bottle left.
