Create your skin profile
The90™ app walks you through a series of questions that help us build your specific skin profile. Genetics, habits, and sensitivities all play a role in how your skin reacts to the sun.
Track UVA & UVB
Know exactly what rays have hit your skin throughout the day, and what that means for your specific skin type. This way you can apply sunscreen or cover up before you burn, and get insights on what you can do to mitigate the aging effects of the sun.
Harness the benefits
We know now more than ever that the sun is vital to our health. With The90™ you can track these benefits like Vitamin D production, so you can maximize the benefits without risking damage from harmful UVA rays.
