Is the sun good for acne-prone skin?
There are multiple benefits to healthy exposure to solar radiation. It has always been a popular idea that people affected by acne see an improvement in the condition during the summer months. But to what extent is this true? Today’s post will explain the sun’s effects on acne.
Does the sun improve acne?
Solar radiation has an anti-inflammatory effect on the skin because it inhibits the processes of repair and regeneration. In other words, the skin becomes more reactive against the external attack of ultraviolet radiation. This means the skin is able to adapt to environmental conditions, synthesising melanin, the natural pigment that protects us from the sun. This is why the sun is beneficial for immune conditions such as psoriasis, other skin conditions such as eczema, and for acne, to a certain extent.
28. It causes a kind of local dehydration of the skin and can assist in regulating sebum production.
So, does the sun help acne? We should be very cautious responding to this assertion, as although it has been observed in multiple studies that there is a minor improvement during the summer, it is also possible for the condition to be aggravated in some individuals, due to vasodilation caused by the sun in skin tissue. Increased permeability leads to a greater risk of the pores becoming blocked, and therefore to worsening acne symptoms.
The sun’s rebound effect on acne
Although the sun does have benefits for acne-prone skin, these are usually temporary, and lesions typically worsen after the end of summer.
This is the case because the flaking caused by local solar damage to our tissues stops happening when we receive less sunlight. When this factor is removed from the equation, the skin is no longer inhibited and recovers its functions, meaning it starts regenerating again and transporting sebum to the skin surface.
The most important thing is not to forget the harm the sun can do to the skin. Solar radiation causes oxidative damage, which accumulates over the years and promotes skin ageing. So sunscreen is essential for two reasons: to prevent the formation of free radicals and to prevent the photosensibilisation of the skin. Acne-prone skin is more sensitive than normal skin due to the effect on cells of inflammation processes involved in the appearance of spots and blackheads.
Protecting your skin from the sun
We recommended trying moderate exposure to the sun if you suffer with acne and you’re not undergoing treatment with retinoids. If the dehydration effect improves your acne then sunbathe, but only in moderation.
Always avoid the time of day where the sun is at its more intense (between 12 and 4 o’clock) and use high-strength oil-free (non-comedogenic) sunscreens.
It is important for specific photoprotection to use products with emollients that do not moisturise to excess, but do protect the skin. Acne-prone skin is more sensitive because of the inflammation of hair follicles caused by bacterial superinfection. Therefore, the products you use should respect your skin’s phototype and have at least SPF 30 protection. We also recommend using gel textures, which will leave a sensation of freshness and hydration. Finally, remember to moisturise your skin regularly.
