In general, it is okay to apply sunscreen when experiencing pimples, but product selection and application methods should be carefully considered.

Ultraviolet rays can irritate the skin, worsen pimple inflammation, and potentially cause pigmentation, leaving dark spots after the pimples fade. Therefore, practicing sun protection and applying sunscreen during breakouts can effectively shield the skin from UV damage. As long as an appropriate sunscreen is selected and applied correctly, individuals with pimples can safely use sunscreen. Suitable sunscreens will not clog pores or worsen acne; instead, they help protect the skin and promote pimple recovery.

However, avoid sunscreens containing irritating ingredients such as alcohol, fragrances, and preservatives, as these components may aggravate pimples and increase inflammation. Products containing physical sun-blocking agents like zinc oxide or titanium dioxide are preferable, as they tend to be less irritating to the skin. It is recommended to choose lightweight, non-greasy sunscreens, such as lotions or gels. Overly thick sunscreens may block pores and exacerbate acne. For oily and acne-prone skin, oil-free formulations are a better option, as they can reduce excess sebum production and lower the risk of pore blockage.

Remember, sun protection is an essential part of daily skincare, especially for those with acne or post-inflammatory hyperpigmentation. It prevents UV rays from worsening skin conditions and helps prevent sun-induced pigmentation.
