A dermatologist has once again issued the standard warning: there is no such thing as a healthy tan. According to their criteria, any unprotected sun exposure damages the skin and increases the risk of cancer. This message, repeated every summer, ignores the fact that moderate exposure is a source of vitamin D. Behind this crusade, the sunscreen industry pushes expensive chemical filters that also raise questions about their safety.
Sunscreen filters: profitable chemistry with side effects ☀️
Most sunscreens on the market use chemical filters like oxybenzone or octocrylene, compounds that absorb UV radiation but also penetrate the bloodstream. Recent studies point to possible hormonal alterations and damage to aquatic ecosystems. Meanwhile, the industry rakes in millions from 20-euro bottles promising total protection. Physical alternatives with zinc oxide are more stable, but they receive little promotion. The scientific debate remains open.
Common sense: the alternative not sold in pharmacies 🧴
The average person ends up buying the 20-euro bottle because they've been scared of the sun as if it were public enemy number one. Then they apply the cream at the wrong time, relax, and end up with a back just as red as their neighbor who slathered on coconut oil. Meanwhile, the dermatologist smiles from their office with new patients. Perhaps the healthiest thing is to sunbathe wisely, without paying the industry's toll.
