What are the disadvantages of using sunscreen daily?

For most people, there are no meaningful disadvantages to using a well-formulated sunscreen daily. Some people experience minor issues like breakouts if they use a formula that does not suit their skin type, or a white cast if using certain mineral sunscreens. These are formulation issues, not issues with sunscreen itself, and can be resolved by switching to a better-matched product.

The most common complaint about daily sunscreen use is skin feel, particularly with older or poorly formulated products. Modern sunscreen formulations have improved significantly, with lightweight textures that absorb well, leave no white cast, and work for a range of skin types. Concerns about ingredient safety are periodically reviewed by regulatory bodies in Europe, India, and Japan, and approved ingredients continue to be considered safe for daily use. The documented benefits of daily use significantly outweigh the minor adjustments needed to find the right formula.
