LED light remedy is a skin treatment it doesn’t use ultraviolet light. Instead, it uses skin-safe, low-level light in several wavelengths and colors. These include:

Amber
Blue
Red
Green

Sometimes different LED lights are combined with a photosensitive drug called 5-aminolevulinic acid. This medicine is applied to the skin and used in a combo with LED light. While this may make your skin more sensitive to light, it helps the treatment — also known as photodynamic therapy — work better.
While the LED light remedy is typically done in a dermatologist’s office, several LED light facial devices are for sale for at-home use. Examples include:
Light facial masks
Light wands for targeted spot treatment
Ultrasonic devices
Mesotherapy electroporation devices
Professional LED light machines
These lights are being used for lots of different skin conditions. Receiving light remedies from your physician is a promising skin treatment, but at-home devices require more research. It’s not entirely clear, for example, whether home light masks work or have lasting effects.

Benefits of Celluma UK LED Light Therapy
LED lights have been available since the 1960s, but have only been used in the past few years to treat the skin. Different wavelengths enter your skin at different depths, creating this therapy useful to take care of a variety of skin conditions, including:‌

Acne. Blue light is often used to treat acne. Studies show that blue light can kill the bacteria responsible for acne. It can also ease how much your oil glands make. This stops the hair follicle from becoming clogged and treats acne.

Red light is also typically used in combination with blue light to help ease inflammation and redness.‌

Aging. Red light stimulates skin cells called fibroblasts. These help to make collagen, that are an important part of skin recovery. Some studies have discovered that red LED light therapy tightens skin, reduces wrinkles and fine lines, and makes skin smoother and softer. ‌

Photodynamic remedy with 5-aminolevulinic acid and LED light also eases fine lines and makes your skin softer.

Wound healing. Red LED light stimulates collagen, which is important for healing wounds. People who have had surgery for skin resurfacing have also got a red LED light remedy following your procedure. Studies have found that this form of light therapy lowers redness, swelling, and bruising, and boosts the healing process.

Hair loss. Red LED light remedy can help stimulate hair growth for those with male- or female-pattern hair loss.

Psoriasis. Red and near-infrared LED light remedies can help lower redness and inflammation in psoriasis. One study showed these light therapies also lowered psoriasis pimples and plaques, or red, itchy, scaly sores.‌

Skin cancers. Photodynamic therapy has been performed using both red and green LED lights to treat skin cancers. After the medication is applied to the skin, red and green lights have been used to take care of Bowen’s disease and red light has been used to treat basal cell carcinoma lesions.

‌Studies have shown that the red LED light is typically superior to the green one in treating Bowen’s disease and also at removing basal cell carcinoma lesions.
Generally, LED light remedy is safe when it’s used alone without sensitizing medications or creams. LED lights don’t damage your skin or skin tissues.
