As the seasons transition, changes to the weather can pose new challenges for our complexion. You may feel like you've just perfected your routine, when rising heat and humidity decides to weak havoc with your skin. We've all been there, but what actually causes our blemishes to bloom in summer? And how can we kick them to the kerb once and for all? We asked Kiehl's skin pro, Paul, to give us the lowdown on why we might need to change our skincare habits in summer, plus, he shares his top ten products for blemish-prone complexions that work all-year-round.

What are blemishes and what causes them?

Blemishes are small, inflamed bumps, or noticeable imperfections on the surface of the skin. An overproduction of oil by the sebaceous glands, often triggered by hormonal changes, can cause blemishes. Excess oil, dead skin cells, dirt, or bacteria can clog hair follicles that can result in blemishes, blackheads, and whiteheads to form.

How can the summer weather affect the skin?

Seasonal breakouts can be due to pores becoming clogged by increased oil and sweat that skin produces as a reaction to higher temperatures. Heat, or humidity can cause bacteria which can get trapped in the clogged pores, resulting in more blemishes.

Research also shows that when the skin is dehydrated from sun exposure it produces more oil to make up for the lack of natural hydration. This in turn, can lead to clogged pores and blemishes.

What other lifestyle or environmental factors can contribute to breakouts during the summer months and why?

During the summer months, travelling may also cause blemishes to form. Anything from airplane travel dehydrating your skin, to simply moving through different climates and exposing your skin to different environmental aggressors can also cause your skin breakout.

As someone with an affinity for all things beauty, discovering fantastic new products is my not-so-secret obsession. Over the years I've tried and tested a mountains worth of creams, serums and cleansers, finding some of my favourite 'holy-grail' products along the way. However, I'm always on the lookout for more ways to nourish my hair, perfect my dewy base, or enhance my skincare routine. Working as a beauty blogger for over 3 years, I've been lucky enough to collaborate personally with lots of amazing beauty brands including Christian Dior, The Body Shop and Dermalogica. I've used the Dermalogica special cleansing gel religiously since I first got it and their products are some of my ultimate skincare faves. When it comes to cosmetics, NARS Sheer Glow foundation is definitely my go-to - I live for a light, glowy base!
