As much as we love the sunshine, we all know too much sun exposure can damage skin and increase the risk of skin cancer. But what about the benefits. Can sun exposure help improve certain skin conditions?
People often ask things like: Is sun good for skin, and is sun good for acne?
Is there any truth in this, and what should people keep in mind when it comes to sun exposure and skin conditions?
You might have heard people with conditions like acne, eczema and psoriasis say sunshine improves their symptoms. There is believed to be some science behind this. In fact, there’s a number of theories as to why sun exposure might help some skin conditions.
The body needs a certain level of sun exposure in order to create vitamin D, which is known to play a role in reducing inflammation. A study published in 2017 found sun exposure triggers the release of nitric oxide. The nitric oxide then activates immune cells found to help relieve eczema. It’s a similar process when people notice their acne improves in the sun. The anti-inflammatory response within the body can improve the appearance of redness, for example. However, it’s important to note that this is a short-term affect and too much sun exposure could worsen acne in the longer-term. Skin can become dehydrated, triggering an increase in sebum production and resulting in more breakouts down the line.
Also, any benefits to skin from sun exposure only apply in sensible moderation. Also, conditions like acne, eczema and psoriasis often have a range of triggers. Managing them can be a balancing act and a case of finding what works best for you. While you might find a little bit of sunshine helps your skin and makes you feel good, summer can bring its own set of triggers too – heat, moisture from sweating, and chemicals in certain suncare products might all aggravate flare-ups.
Bottom line, keeping skin protected in the sun should always be top priority, regardless of your skin type. Skin cancer can affect anybody, so being sensible and always wear a suitable SPF-containing sunscreen when outdoors. Fragrance and alcohol-free, mineral-based formulas tend to be more gentle for sensitive skin. Find out more in our information video on top tips for sun safety.
