There is nothing fair about acne. Not only does it crop up at the most inconvenient of times, but it is notoriously hard to treat and can have a detrimental effect on self-confidence. Part of the frustration of Winter acne is the fact that we were SURE our oily breakouts were confined to the warmer weather months. Ooooh no. Dermatologist Dr. Jennifer Linder explained to Teen Vogue  “The wind and lower humidity can lead to surface dehydration. If the skin’s moisture is not replaced, the skin’s only defense is to produce more oil.he bacteria responsible for breakouts can’t live in the presence of oxygen. If your skin becomes very dry, it actually creates an environment in the pores where bacteria can thrive.” "The bacteria responsible for breakouts can’t live in the presence of oxygen. If your skin becomes very dry, it actually creates an environment in the pores where bacteria can thrive.” The clincher here is finding the right treatment that will help to clear up the acne WITHOUT drying the skin. Harsh products like benzoyl peroxide are definitely a no-go. La Roche Posay have some great products for combination, acne-prone skin, which will eliminate excess oils without drying you out. The Effaclar 3-Step kit is a fantastic system that doesn't irritate in the colder weather. La Roche Posay Effaclar Anti-Blemish system, RRP: €34.99  The temptation with acne is to avoid moisturiser altogether, however in colder weather, it's imperative to keep skin hydrated to avoid your oil glands becoming confused. Our fave is the Clarins Multi-Active Jour & Nuit skincare duo, particularly the day cream. It's smooth gel texture absorbs instantly, feels light, fresh and non-greasy and doesn't cause breakouts. It also contains an SPF, something that is important all year round but is often forgotten about! Multi Active Day (Cream Gel, Cream Dry, Lotion, SPF 20) RRP €57.
