Benefits of IPL for Sun Damage

Exposure to the sun every other day produces more skin pigment than sunbathing every day — but protection is still vital.

UV ratings indicate risk of skin damage — but they're based on pale skin. New wrist bands designed for six different tones of skin provide a more personalised way to track safe UV exposure. UVA rays reach the dermis and cause skin pigmentation, known as the "Meirowski phenomenon", a grey-brown colouring visible immediately after a long exposure and gradually fading in a few hours.

This is especially true for people with naturally dark skin. The lesions are directly dependent on the dose received. It is a destruction of skin immune cells because ultraviolet radiation inhibits the immune system by inducing the suppression of delayed hypersensitivity HSR and the tolerance of photo-induced skin cancers. It occurs a few hours after sun exposure with a maximum intensity of 24 hours after exposure.

It has 4 stages of severity depending on the sunlight or skin colour: pink erythema, bright red erythema, cyanic erythema, oedematous erythema. This is due to UV rays that stimulate the multiplication of epidermal cells called keratinocytes, which leads to a thickening of the horny layer, which contributes to natural photoprotection.

Over time, the effects of UV rays are cumulative and their severity level depends on the total dose received and the quality of the individual's natural photoprotection. Before the first exposure, you must adapt your beauty routine and make way for a special summer program! The essential gesture is to deeply moisturize the skin, as the sun tends to dry it out and make it more fragile.

At Laboté, we rely on a application of our serum associated with the day cream revisited for the summer season. Since all our treatments are tailor-made, this is the perfect opportunity to adapt them to your skin. It is important to take into account your skin type and sunlight conditions. Sun damage happens to skin when a severe sunburn harms the deep tissue of a fair skinned individual resulting in spotty discoloration. This type of pigmentation can be the most difficult type of discoloration to be treated in a topical manner.

IPL or Intense Pulsed Light is often used to treat sun spots, age spots, rosacea and other forms of skin discoloration. Often times this treatment is referred to as a photofacial or photorejuvenation.

IPL works by heating up and destroying damaged skin cells with the darker pigmentation. The treatment is administered over the surface of the face, neck or chest through quick and powerful flashes of light.
