We break down why SPF moisturiser is important for acne and oily skin.
Sun exposure, pollution, make-up and dehydration can all worsen the appearance of acne breakouts, oily skin and acne scars. Here's why:
UV radiation dehydrates skin, causing it to over-produce oil – so skin ends up even oilier. The sun's UVB rays also cause sunburn and peeling, which generate excess dead skin cells. Excess oil and dead skin cells are two of the main factors that contribute to acne. Together, they clog follicles (pores), increasing the chances of breaking out.
If you have acne scars, UV rays can make them darker and more noticeable because scar tissue is highly sensitive to sunlight. Darkening is the skin's way of protecting itself from further damage.
Airborne pollution also leads to skin dehydration and excess oil production, as well as inflammation, which makes existing acne look worse. Studies show that oily skin and acne increase with pollution, and that the effects of pollution may be even worse with UV exposure.1, 2
Going to bed with make-up on, or applying make-up over make-up from the day before, contributes to acne cosmetica, or acne that develops from wearing make-up. Telltale signs of acne cosmetica include many tiny bumps (whiteheads) on the cheeks, chin, lips, or forehead.
Not only is skin dehydration caused by UV rays and pollution, it's also caused by lifestyle habits like over-exfoliating and taking hot showers. These habits can compromise the skin's naturally protective outer layer, which is responsible for keeping moisture in.
To help protect your skin against all of the above, apply a mattifying SPF moisturiser like Clearing Defense SPF 30 every day. Clearing Defense SPF 30 provides a long-lasting matte finish while countering the dehydrating effects of environmental stress and stopping oil-based make-up from clogging pores. Best of all, it washes away easily with a Dermalogica Double Cleanse, keeping pores clear of congestion. Be sure to cleanse your skin and moisturiser regularly to help decrease your chances of excess oil and acne.
