TikTok’s ‘sunburning’ acne trend: Why dermatologists say it could make things worse

A viral TikTok trend called 'sunburning' has young people intentionally exposing their skin to sunlight in hopes of clearing up acne. Dermatologists warn that this method could potentially worsen the condition. According to Dr Nirupama Parwanda, a dermatologist from New Delhi, UV rays can reduce inflammation and bacteria that cause acne temporarily.

However, the effects do not last long and increased oil production can make acne worse. Dr Prerna Sikka, another dermatologist, explains that UVB rays can harm skin cells by causing apoptosis (cell death) and generating reactive oxygen species (ROS), which can kill acne-causing bacteria. Yet, excessive sun exposure increases the risk of skin cancer, especially melanoma.

Dermatologists note that UV rays can thicken the skin's outer layer, trapping sebum and bacteria in pores and causing more breakouts. While sun exposure may temporarily reduce oiliness in acne-prone skin, the effect is not long-lasting, and the skin might respond by producing more sebum, worsening acne. Long-term sun exposure can lead to hyperpigmentation and premature skin ageing.

Dermatologists recommend alternative treatments for acne, such as oral therapies, retinoids, salicylic acid, benzoyl peroxide, and lifestyle modifications.
