The simplest answer to this question is no; unless you take precautions.
So, what does tanning do to you?
Not only does it come from the burning of your skin, which can cause skin cancer, but tanning also allows very harmful UV rays to penetrate your skin and damage your DNA.
When Dr. Roxana Daneshjou, a dermatology resident at the Stanford University School of Medicine, was asked about tanning her response was, “There’s really no such thing as safe tanning, other than putting a fake color on your skin. Fairer-skinned people may not even tan until they burn.”
It’s also important not to make the mistake that the more burnt you are the worse, as even the skin damage at the very start of the tanning process is still very dangerous itself, according to Dr. Daneshjou.
Dr. Daneshjou also noted that people who tan for aesthetic reasons are hurting themselves in the long run.
She explains this as melanin in the skin absorbs UV rays to a point, acting as the skin’s natural sunscreen, but the process of adding an extra dose of melanin to the skin (a.k.a. tanning) is a defense mechanism that begins only after damage has been done.
UVA Rays break down the natural collagen (skin’s support structure) in the skin, which can lead to premature aging.
Without this support, structure skin wrinkles, thins and weakens, taking on a papery appearance.
Dr. Daneshjou claims no anti-aging product, even the dermatologist-recommended ones, can slow skin aging as much as simply using sunscreen in the first place.
To prevent these kinds of problems, dermatologists recommend everyone use sunscreen (broad-spectrum products specifically) year-round.
UVB exposure increases in the summer and decreases in the winter, but UVA exposure occurs year-round.
Both forms of UV light can pierce through windshields and clouds. causing damage on even cloudy days.
Anytime you plan to be outside for an extended amount of time you should apply an FDA registered, Broad Spectrum, SPF 30+ sunscreen product.to reflect harmful UV rays.
