Light-emitting diode therapy (or LED for short) is nothing new. Having long been used in professional treatments, the benefits of LED for acne-prone, rosacea-ridden, discoloured, dull and ageing skin come with regular use. While this might deliver great results, it has previously been a costly and time-consuming approach in the pursuit for healthy skin.
And thus, the emergence of at-home skincare devices, led by LED treatments in the form of targeted on-the-spot gadgets and full face masks, are becoming popular for consumers who want to maintain the results of in-clinic treatments and the efficacy of carefully curated skincare routines. According to global market researcher Mintel, 41% of beauty consumers use skincare devices to prolong the effects of professional treatments. With better access to information, technological advancements and more transparency from brands, high-performance products are no longer exclusively available in costly facials and specialist clinics. Plus, LED light treatments are the most pain-free facial you can have, with no tingling, side effects or downtime needed. What more could you want?
Here are all your questions about LED light therapy answered:
What are the benefits of LED for the skin?
“LED light emits therapeutic wavelengths of light energy to energise cells,” explains Laura Ferguson and Hannah Measures, co-founders of The Light Salon. In doing so, the light energy stimulates the production of collagen, elastin and antioxidants while improving blood and lymphatic circulation. It’s a treatment that is suitable for all skin types and is designed to be used after cleansing and exfoliating, followed by your serums and moisturiser.
How many different types of LED lights are there and what is the difference between them?
“Different light spectrum penetrates the skin in different depths and has different effects. Red and blue LED light therapy combat numerous issues, including but not limited to, dullness, fine lines and wrinkles, inflammation, redness and swelling. They replenish dermal and epidermal cells, stimulate the natural production of collagen and elastin and speed up the recovery process,” explains Dr Dennis Gross, dermatologist, dermatologic surgeon and founder of Dr. Dennis Gross Dermatology.
Near-infrared light is another option, suiting inflamed skin best as it stimulates the skin’s healing and regeneration process by delivering nutrients and oxygen to problem areas, leaving you with strengthened and brightened skin. If acne is a concern, Ferguson and Measures recommend red light as it has an antiseptic effect on blemishes and reduces inflammation and painful swelling within the spot to help speed up the healing of the area. Impressively, when used together near-infrared and red light are clinically proven to reduce the appearance of fine lines and wrinkles.
What’s the difference between an LED treatment in a clinic and an at home device?
At-home devices don’t have the power of the professional machines used in LED light therapy treatments, but Ferguson and Measures explain that if you use an LED light mask three times a week over a four week period, it delivers the equivalent cumulative dose of light as one salon treatment, if you went once a week for the same period. “Results are instant and long-term and because LED light therapy works on a cellular level, so you leave with a glow, which becomes more pronounced with each treatment. Think of it in terms of a workout – going once is better than not going at all, but if you make an effort to stick to regular sessions, you’ll get great cumulative benefits.”
