The sun aggravates and accelerates the appearance of skin aging and its “harmful” effects can appear more than 10 to 20 years after irradiation. Prolonged exposure to ultraviolet rays will be responsible for the appearance of brown spots. If it is strongly advised against going out in the sun after having performed a peeling, it is on the other hand possible to repair your skin after too intense an exposure.
Peels accelerate skin renewal by exfoliating the superficial layer. The skin rebuilds itself in a smoother way by erasing a number of irregularities such as enlarged pores, sebum deposits, dark spots, acne, blackheads and fine lines. The aim is to restore the skin to its full radiance, to restore the face, neck, décolleté or hands to a smooth, youthful appearance with an even color.
The three main classes of peels are called gentle (or superficial), medium and deep. The most common types of acid used are fruit acids, TCA and phenol. Fruit-based peels, the most common of which is one containing glycolic acid, are very effective. Called on Lunch Peeling, it is highly sought after because it does not cause any withdrawal from social life. Other peels should only be performed by a doctor and lead to a social eviction of 1 to 2 weeks. In aesthetic medicine, peeling is considered an act of skin resurfacing (exfoliating the superficial layer of the skin) with the use of an acid chemical agent or an acid natural agent.
Peels increase sensitivity to the sun
I’glycolic acid used in peeling agents increases sensitivity to the sun. Nevertheless the care products can be used in summer and it is essential to use in addition to any treatment withglycolic acid sun protection. We advise you to protect yourself in all cases. But whatever the case, exposure to UV rays is strictly prohibited after the treatment. To protect the epidermis, a total screen must be applied for one month after a peeling superficial, and lasting at least six months for a deep peeling.
Peels treat brown spots caused by the sun
The brown spots which alter the unity of the complexion come from prolonged exposure to ultraviolet rays, associated with the use of a product (the pill or certain medications) which accentuates the effects of the sun. The pregnancy mask or chloasma is a pigment spot that can be caused by sun exposure in pregnant women. Indeed, pregnancy causes an increase in the levels of female hormones, at the same time leading to an increase in the synthesis of melanin. If during this period, the skin is exposed to the sun, there is hyper-pigmentation and the appearance of spots, especially on the face. In this case, the pregnancy mask is mainly located on the forehead, temples and cheeks.
Sunspots appear on the hands and on the back are and are mainly due to skin aging, but also to excessive exposure of the skin to the sun. In some places, the melanocytes start to function much more for unknown reasons. Melanocytes are the cells that pigment the skin. They can be located in the dermis or in the epidermis. They produce melanosomes (pigmented granules rich in melanin). With age, small pigmentation disturbances appear. Melanin (dark skin pigment responsible for tanning) becomes disorganized and creates small brown spots or age spots.
The peeling is with the Nd Yag type pigment laser and the Fraxel laser one of the solutions to treat these brown spots. The effects of peels have been well studied. At epidermal level, there is total melting, therefore disappearance of anomalies in the balance of the different cell populations: reduction in the thickness of the stratum corneum compared to the total height of the epidermis, but increase in this total height and disappearance of the melanic overloads. It should be remembered that a medium peel can always have the secondary effect of causing sometimes very dense post-inflammatory pigmentation, occurring around the 20th day. It is for this reason that a medium peel must always be framed by prescriptions with melanocyte tropism.

Tru Niagen is nicotinamide riboside , a unique type of vitamin B3. Niagen is a NAD+ precursor that acts as a building block for the production of NAD+ in your body. This is significant because NAD+ is an essential coenzyme for cellular health; yet, NAD+ levels fall with aging and other physiological stressors including poor food, alcohol, lack of sleep, or too little or too much activity. Tru Niagen has been clinically demonstrated to aid in the increase of NAD+ in the body. Niagen is the first and only patented and FDA-approved nicotinamide riboside product.
