The SPF rating on your sunscreen only pertains to the amount of protection from the UVB or burning rays. Tanning is actually the result of your body trying to protect its DNA within the nucleus of the skin cells. UVA rays are the rays that cause damage to the matrix of the skin, and the amount of UVA protection is not required as of now by the FDA on sunscreen packaging. The melanocytes, or cells responsible for producing melanin (tan) in your skin, are stimulated by any type of heat or trauma, so in answer to your question, it is possible to tan with a high SPF product. However, please be aware that DNA damage occurs with UV exposure, and can cause premature aging and skin cancer. Tanning booths offer a false sense of security, and can actually increase your chances of skin cancer. The latest figures are that if you tan even once in awhile in a tanning bed between your teens and early 20s, you increase your chances of melanoma 25%. Your best bet is to use the self-tanners or go get a spray-on tan!!
Yes. But very, very, slowly. It will take you twice as long than if you used Spf 15.
130 minutes?
Use sunscreen. SPF 30 (but you will not get tan)
In order for any sun tan product to provide any protection it has to have a high SPF number. The lower the SPF number, the lower the protection. Most dermatologists recommend an SPF number of at least 30.
How long is the vacation? You are still apt to burn with fair skin if you are using SPF 15 for 7-10 days longer.
This depends where you are located. In hotter countries i used 30 and got an amazing tan! But in places such as Canada and Cooler States i often only use a 15 and don't get nearly as great of a tan. If you want a hot tan for back to school, or even just to feel great about yourself; you might have to experiment with different SPF's and different brands. Yes, even brands will determine how much of a tan you get. If you have paler skin start with a 30 (or higher) and work your way down as you get more tanned. If you are darker skinned I would start with a 15, and see how you are from there.Good luck, and hope this helped my soon to be gorgeously tanned friend.(EDIT BY KABOB34: SPF 8 is good, as well as SPF 15.)
An SPF of about 30
Neutrogena makes a spf 30 lipgloss.

No. SPF 30 lets in 1/30 of burning UV rays, while SPF 50 lets in 1/50. Adding the two together is pointless and would not result in high levels of skin protection.

Should be UVA and UVB. Read the labels, and use at least SPF 15 up to SPF 30 if you are very fair or freckle easily.
It was probably SPF 30 because that blocks 96.7% of UVB rays. SPF 50 blocks 98% so you aren't really getting that much more protection than the SPF 30. Neutrogena has a SPF 100 but it really isn't necessary because as I said, SPF 30 is already blocking a significant amount, and SPF 50 doesn't even make that much more of a difference. Just for your information, SPF 100 blocks 99% of UVB rays so it REALLY doesn't do much more than SPF 50.
Yes, that is exactly what it is designed for, as tanning - any amount tanning - is damage to your skin. There is no way to reverse it, and it's ultimate destination is skin cancer.
