I have tried a variety of indoor tanning lotions that contain bronzer. Black Storm 60X has got to be one of the best indoor lotions to inhance the skin fast and I mean fast. I used this lotion without a base tan on my first tanning visit of the season and I noticed color only hours after the first visit. This lotion helps speed up the tanning process and within 3 visits I had a light bronzed tan and my skin never burned trying to build a base tan. I got as dark in 1 trip to the tanning bed with this lotion than I normally get after about a week of consistant tanning (3-4 visits a week). This is an impressive tanning lotion! I It really does boost your tan, and quite quickly. Another benefit is the smell, I'm always having to schedule my tanning session when I can shower soon after or have nothing to do the rest of the day but I can tan, and still go out because of the banana coconut tropical scent this lotion leaves on the skin. Black Storm 60X is silicone enhanced which is a nice touch for this lotion as well. Silicone is a great skin firming tool, so it certainly gets that job done. I've noticed I don't peel nearly as much as I did with other lotions so that's another great plus. I can tell that my skin has gotten much more refined and firmed due to the silicone enhanced formula. Effectiveness Lotion formula is meant to speed up the tanning process with bronzer built in the lotion. A bronzer is a self tanner which turns the skin brown, or tan. This lotion works fast and leaves skin very tan.
