Are those tanning products harmful for the skin?

I am talking about cremes and lotions that tans the skin for about 3 or 4 days.

Are those tanning products harmful for the skin?
Tanning with the self tanning lotions cannot hurt you. Its definatly 100 times better than sitting in the sun or getting in a tanning bed. If they were harmful to your skin they wouldnt be sold. And you dont get a orange color if you use a product that gradually tans your skin.
Reply:No but it leaves your skin with this ugly orange looking color.
Reply:No but it's just better not to use them.
Reply:They deffinitely can't be near as harmful as actually sunbathing or going to the tanning bed. That is a great way to get skin cancer by 35 and then you have ugly wrinkly looking skin. I don't "tan"(purposely spend extra time in the sun to do so) but i get a tan after swimming or something. being a guy, i've never really worried that much about it so i've never used tan creams or anything like that. Also depends on the product, some lotions might have an ingredient that may harm the skin. chek w/ a dermitologist on it first tho.
