Lots of things can cause unevenness in your skin tone from environmental stress, hormonal changes, certain medications, acne and some skin disorders but in men the most common cause is sun damage, though cuts, scrapes and abrasions can also result in uneven skin tones. The easiest way to prevent this kind of pigmentation (apart from staying out of bar brawls!) is to protect skin on a daily basis with a sunscreen. Exposure to UV light can result in clumps of melanin (the skin’s natural pigment) to form in the skin and can lead to uneven colouration. One of the most obvious signs of this are Solar Lentigines (patches of pigmented skin) which are often found on bald heads that have been exposed to the sun.
Of course, we automatically reach for the sun lotion in the summer but it’s worth guarding against UV exposure all year round by using moisturisers like Anthony Logistics Facial Moisturiser SPF15 which contain a built-in sun screen. Apply every morning and switch to your regular, non-SPF, moisturiser at night.
