Most sunless tanners contain dihydroxyacetone, or DHA, which is a colorless sugar compound primarily derived from sugar cane and sugar beets. DHA reacts with amino acids in the skin, and it produces that browner hue. The reaction only affects the dead skin cells of the outermost layer of the epidermis. That’s why sunless tanners usually only last for about five to seven days after application.
Sunless tanning products are infinitely safer than getting a tan caused by UV radiation. UVA and UVB rays will wreak havoc on your skin, leaving both temporary and long-term damage. Wrinkles and burns aside, it will absolutely put you at risk for developing skin cancer.
Always continue to utilize protective clothing, hats, and sunscreen. When possible, seek out shade, and don’t forget your sunglasses. When choosing a sunscreen, reach for something that is SPF 30 or higher.
