Can we shower immediately after a tanning session?

During a tanning session, whether natural or artificial, the synthesis of melanin by melanocytes is activated in response to UV ray exposure. This process primarily serves a protective role for the epidermis, but also incidentally results in a sun-kissed complexion. When exposing oneself in this manner, it is important to adopt certain practices, among which includes the application of a broad-spectrum sunscreen. This complements the protection provided by melanin and limits the damage caused by UV radiation (sunburn, dryness, skin conditions...).

After returning from the beach or sunbathing, the desire to shower and remove all the sunscreen from the skin's surface is quite strong. However, there is often a fear that water, soap, or the friction of skin under the shower may be harmful to the tanning process and alter it. Rest assured: there is no connection between washing after a tanning session and the durability of the coloration, which typically lasts about a month. Indeed, the mechanism by which tanning fades is cellular differentiation, that is, the maturation of epithelial cells that load up with keratin to become dead cells (corneocytes) making up the horny layer and eventually being shed. This process is internal to the skin and is not influenced at all by the surface phenomenon of taking a shower.

Note : if you have applied a self-tanner to your face or body, wait at least 6 hours before taking a shower. It is indeed important to wait, as there is a risk of rinsing off some of the product and ending up with a non-uniform tan and areas that are more colored than others.
