Sunscreen May Cause Acne; Doctor Highlights Key Factors

Many individuals struggle with persistent acne despite daily sunscreen use, questioning their suitability for such products. Dermatologist Huang Hsing-wei explains that the issue often lies not with the sunscreen filters themselves, but with other components in the formulation.

“

Many times, the problem is not necessarily the sunscreen filter itself, but rather the oils, emollients, heavier carriers, and waterproof, sweat-resistant film-forming formulas.

Huang notes that oils, emollients, heavy bases, and film-forming agents used for water and sweat resistance can contribute to clogged pores and breakouts. Specific ingredients like Isopropyl Myristate, Isopropyl Palmitate, Myristyl Myristate, and Ethylhexyl Palmitate are frequently discussed, though not everyone reacts to them. Similarly, natural oils such as Coconut Oil, Cocoa Butter, and Wheat Germ Oil can be problematic for those with oily or acne-prone skin.

“

So, 'chemical sunscreen' does not necessarily mean it causes acne; 'physical sunscreen' does not necessarily mean it is safe from causing acne. The real key is: ingredients, texture, and skin compatibility.

Ultimately, Huang emphasizes that neither chemical nor physical sunscreens are universally "good" or "bad" for acne. The crucial factors are the product's texture, its compatibility with individual skin types, and whether it feels overly heavy or occlusive. Proper cleansing is also vital for acne-prone skin, especially for those wearing masks for extended periods.

When choosing sunscreen for acne-prone skin, I usually care more about: whether it is too heavy, whether it easily clogs pores, whether it is suitable for long-term mask wearing, and whether it can be completely removed; rather than just looking at 'physical or chemical'. Because what suits you is good sunscreen!
