I cannot praise enough the effectiveness of Off Skintastic. It is by far the best I have used. With 15% DEET it does the job without overdoing it. Though DEET has been shown to be non-toxic when used as directed, I am very cautious when using these products. It is wonderful to have such a useful product and not smell like you were bathing in chemicals. Not only does it smell and feel nice, I do not get that burning sensation when applying it. Previous to this product, I usually avoided insect repellents. Now I use it on a regular basis and enjoy the outdoors more. Were it not for this product, after being outside a couple of hours, I would be all bit up!!!
