Is your SPF causing breakouts? We ask a dermatologist for advice via IrishTimesLife
Since her advice and expertise cleared up my perioral dermatitis a couple of years back – it’s an unbelievably stubborn red, goatee-like rash around the mouth and nose which requires medication to clear and is common in Ireland – London-based Northern Irish dermatologist Dr Sam Bunting has become my go-to for tricky skin quandaries. Women over 30 are more prone to acne and hormonal breakouts, but we are also among the most sun conscious.
To clear up the confusion , I asked Dr Sam the question that seems to be on the minds of the breakout-prone – “Is SPF making my breakouts and acne worse?” Her answer? The right SPF actually helps to prevent breakouts and acne flare-ups. For anyone who wants to maintain skin clarity in summer, SPF is essential.
“In the short term, people like the impact of UV rays because they have a mild anti-inflammatory effect. We even use UV to treat conditions like eczema – and more commonly psoriasis – because of these effects,” Dr Sam explains. When it comes to acne, though, the key phrase is “short term”. “At the same time, UV exposure also promotes comedogenesis. You get this thickening of the outer layer of skin as a defence mechanism against UV.
So while sun exposure can temporarily make skin look clearer, it directly causes breakouts shortly after. “Typically you come in out of the sun and your skin is clogged and you break out badly. If you then use a sunscreen that isn’t non-comedogenic [designed to be non-congesting], you have a perfect storm for breakouts. UV will also darken those post-inflammatory marks.”
