High-tech red light therapy is trending on TikTok and ‘all skin types can benefit,' dermatologist says: Here's what to know

If you regularly scroll on TikTok, you’ve probably noticed users wearing masks that illuminate red light. Red LED light therapy has become popular in the US for skincare, offering benefits such as clearer and healthier skin, and anti-aging effects. At-home red light therapy masks can range from under $100 to $3,500. Experts say that red light therapy can penetrate the skin and promote collagen production, aid in pain relief, reduce inflammation, and even promote hair regrowth. It is important to use FDA-cleared LED light devices and follow the instructions for safe use. People with certain conditions should consult with their doctors before trying LED light therapy. Overall, LED light therapy can be a non-invasive way of improving skin health at home.
