Dermatologists largely agree that self-tanner is a far safer alternative to sunbathing or tanning beds, but they caution it is not entirely without risks. As the trend of using self-tanning products intensifies, especially during spring events like Seville's Feria de Abril, experts stress the importance of understanding what these products do to the skin. The active ingredient in most self-tanners, dihydroxyacetone (DHA), reacts with dead skin cells to produce a temporary tan, but concerns remain about inhalation and long-term effects.
Why Self-Tanner Is Considered the Lesser Evil
Skin cancer rates are rising, and dermatologists have long warned against intentional tanning. UV radiation damages DNA and accelerates skin aging. In contrast, self-tanner does not involve UV exposure, so it doesn't carry the same carcinogenic risk. "It's the lesser evil by far," says one dermatologist, echoing a common view in the field. For those who want a bronzed look, self-tanner is a compromise that avoids the most serious harms.
What's Actually in the Bottle?
Most self-tanners rely on DHA, a simple sugar that browns the skin's surface. Some also contain erythrulose for a longer-lasting effect. While DHA is approved for topical use, the FDA has cautioned against inhaling or ingesting it, and there are no long-term studies on its safety when used repeatedly over years. Dermatologists recommend patch testing and avoiding products with added fragrances or harsh chemicals if you have sensitive skin.

The Trend: From Beauty Hack to Competition
Social media has amplified the use of self-tanner, turning it into a competitive sport. A recent TikTok trend in Spain saw users comparing their tans with a "tan meter," sparking debate about unrealistic beauty standards. While dermatologists don't oppose self-tanner per se, they worry about the message that darker is always better. "The goal should be healthy skin, not a specific shade," one expert notes.

Who Should Be Cautious?
People with sensitive skin, eczema, or rosacea may find self-tanners irritating. Those with lighter skin tones might notice uneven results. Pregnant women should consult their doctor, as some ingredients haven't been studied extensively. And everyone should avoid self-tanners on broken or inflamed skin. "It's not a free pass to skip sunscreen," says a dermatologist. "Self-tanner offers no UV protection."

How to Use Self-Tanner Safely
To minimize risks, dermatologists suggest choosing products with short ingredient lists, applying in a well-ventilated area, and washing hands afterward. Exfoliating before application helps avoid streaks. And always use sunscreen outdoors, because a fake tan won't stop sunburn.
