How Skin Treatments With LED Or Laser Lights Work

2 min read

Dermatological treatment like Laser Acne Treatment in Minnesota for example with photo biomodulation may be indicated for acne, rosacea, melasma, and skin aging. You may already know that light can be therapeutic for many health conditions.

We use ultraviolet B-light to treat psoriasis, vitiligo, and ultraviolet A-light for mycosis fungoides, a type of cutaneous lymphoma.

In the case of UVA and UVB lights for treating skin diseases, the mechanism of action is anti-inflammatory, and therefore, the right amount of energy released by the light is fundamental.

Today we also use intense pulsed light, which emits different lights to treat stains, vessels, and even hair removal. These lights act through selective photo thermolysis, attacking targets such as melanin and hemosiderin through heat. The amount of energy chosen is also critical to preventing skin burns.

Today, photo-bio stimulation through LED lights and the low-power laser is also possible, which can improve several dermatological conditions. In this case, LED lights or low-power lasers treat the skin by photo modulation, whose parameters will be adjusted according to the treatment condition.

Several devices emit light between 630 – 650 nm to treat capillary stimulation and improve alopecia. There are also systems with varied protocols that combine specific assets and wavelengths for numerous skin diseases. This way, we can treat acne, rosacea, melasma, and photoaging. In this system, peeling is used to improve the entry of the specific activities in each case, promoting the interaction between the affected structures and the LED or laser light.

Therefore, alpha hydroxy acid peeling is combined with actives such as aminolaevulinic acid and blue light to treat acne.

Still using acne as an example, aminolaevulinic acid makes the bacteria that compromise the site more sensitive to the action of light. The sebaceous gland is also more sensitive to light, which promotes photo-bio stimulation of the acne-affected region.

The laser can treat cosmetic flaws such as wrinkles, acne scars, aging, and sun-damaged skin. The layer of skin where the wrinkles, scars, and blemishes are is damaged and vaporized, making room for a new layer of skin to form. The process also offers greater control over the depth of penetration on the skin’s surface, allowing for greater precision and safety in the case of delicate areas.

Another indication of the laser which can be done in Metropolitan Skin Clinic for instance is for rejuvenation in the improvement of fine lines, wrinkles, and lines of expression on the face, as well as the appearance of the eyelid, crow’s feet, and region around the eyes. It also removes blemishes and skin irregularities; improves and evens out scars and skin tone. In addition, it can also be used to remove unwanted hair and tattoos.
