Myths and facts about sun and acne
A lot of people think that sun exposure can relief acne breakouts and that getting a tan can camouflage the imperfections. The truth is that even if a light tan may trigger a temporary improvement covering the reddish areas, in the longer terms the effects of UV rays will worsen the conditions of acne.
Beyond doubt a moderate sun exposure has positives effects on our body and our mood. UVs stimulate vitamin D production that is crucial for many of the vital processes in our body and sunlight positively affects the levels of serotonin called the ‘happy hormone’. Nevertheless, there are various reasons why an excess of sunlight can cause unpleasant side effects on acne-prone skin.
The increased production of sweat in warmer conditions causes the proliferation of the bacteria associated with acne (P. acne).
UV rays dry out the skin surface and the sebaceous glands (which produce the sebum that gives skin the oils it needs) increase their activity. The surplus of sebum (Seborrohea) − is the first step in the development of blemishes.
When the skin dries out the cells on the surface harden and this prevents the sebum from being able to drain from the pores. The result is the development of comedones.
People with acne are particularly prone to hyperpigmentation and therefore more exposed to this issue often related to an excess of sun exposure. On acne prone skin tanning can cause dark spots and scarring to appear after pimples heal.
On top of this, the sun can trigger a specific kind of acne (Acne Aestivalis) when UVs combine with the chemicals in certain skincare products producing an allergic reaction.
An effective and appropriate sun protection is essential for people having blemish prone skin in order to get the advantages of a safe and moderate UV exposure.
