Importance of sun protection after facial treatment

Why should you protect yourself from the sun before, during and after a facial treatment and especially in professional treatments for hyperpigmented skin?

Our skin is formed by cells, among them we have the pigment forming cells called melanocytes, which are generated by a mechanism called melanogenesis and this gives rise to the synthesis of melanin. Two families of melanins are produced: eumelanin, which is brown or black, and pheomelanin, which is yellow or orange-red.

Melanin is the most important endogenous protection factor available to our skin. It acts by absorbing radiation with wavelengths between 350-1,200 nm. Exposure to the sun stimulates its production.

When we treat skin hyperpigmentation, we try to inhibit the different mechanisms that activate melanin stimulation. Nowadays it is much more important to protect ourselves from the sun as we have a very weakened or destroyed ozone layer and the earth has changed its position with respect to the sun which means that we are closer to it and the UV rays that enter the earth are more harmful than those of 50 years ago, This is why protection methods have evolved and we must adapt to the most modern, apart from the sunscreens that we have from 15 to 130 SPF, we must also use sunglasses or sunshields that have a high level of protection against UVA,UVB, visible light and infrared.

These measures should be taken not only in summer but also in winter as the change in temperature and what they call Reflective surfaces: such as snow, flat water surfaces, and to a lesser extent, sand, grass and undulating water surfaces can lead to very large increases in sun exposure. This sun damage will be clearly reflected in your skin by dehydration, photo-aging and unwanted sun spots.
