LED Light is particularly effective in treating dermatological conditions such as acne or rosacea.
Already used for seasonal depression and sleep disorders, light therapy also offers benefits for the skin. When discussing skincare, the term "phototherapy" is used, which refers to a treatment using LED light. This therapy mimics different colors of sunlight, devoid of UV rays, making it safe for the skin and overall health.
A Cool Light
Unlike lasers, LEDs emit a cool light whose waves penetrate the skin to boost collagen and elastin synthesis and stimulate fibroblasts, youthful cells.
Each color of LED light penetrates at varying levels and offers different benefits. Red light penetrates the deepest. It has anti-aging effects, reduces scars, enhances hair growth, increases microcirculation, and thus nutrient delivery. Green light improves skin radiance and diminishes sun-induced pigmentation. Yellow light addresses redness while improving blood and lymphatic circulation. Finally, blue light boasts potent anti-infective properties. It's used to combat bacteria and balance sebum production, especially in cases of acne or oily skin.
An Effective Acne Treatment
Today, phototherapy sessions are trending towards beauty applications. Many consumers use it to further enhance their skin's appearance. However, it's easy to overlook its potential to address persistent skin conditions like acne.
It's a non-invasive yet effective practice with powerful anti-inflammatory properties that can balance sebum production, tighten pores, and target the bacteria responsible for acne, known as "p-acne." Of course, for these specific concerns, phototherapy sessions should be combined with good skincare hygiene and a healthy diet to yield the best results.
Phototherapy: A Niche for Cosmetic Brands
Several well-known cosmetic brands have ventured into phototherapy devices, creating high-tech beauty accessories. Neutrogena was a pioneer in this realm, developing the first at-home anti-acne mask equipped with blue and red LEDs. Its main purpose is to eliminate acne and promote cellular renewal for skin self-healing.
Foreo, the Swedish brand specializing in beauty tools, has also introduced a device combining thermotherapy, cryotherapy, and light therapy. The device can be controlled via a smartphone app. Its modern design is eye-catching. The red, blue, and green LEDs assist in mattifying, rejuvenating, brightening, hydrating, regenerating, and balancing, depending on the complementary mask used. The brand has recently launched a new range of masks made from top-quality natural ingredients that are cruelty-free. Bulgarian rose, manuka honey, acai, green tea, coconut oil... there's something for all preferences, skin types, and concerns.
However, professionals recommend undergoing phototherapy sessions at medical aesthetic and dermatology clinics. These treatments require the expertise of a specialist, both during and after the sessions. Moreover, consumers might not always have the necessary knowledge to identify their skin's needs and could use LEDs that are not suitable. While they are generally safe, a professional brings the necessary expertise that patients require.
