Sun spots, as the name suggests, are small discolored skin patches caused by repeated exposure to UVA and UVB rays emitted by the sun. They’re also sometimes referred to as "photodamage" or "solar lentigines." While some skin darkening after sun exposure is unavoidable, permanent damage occurs with repeated exposure. As such, sun spots are most common in people above 50 years old, but they can develop at any time. Unlike dark spots, sun spots are more common in those with lighter complexions.

As we get older, our skin changes in several ways. Collagen and elastin production slows, the skin gets drier, and melanin begins to build up within the skin. Research indicates age spots typically appear on skin frequently exposed to the sun, so as you get older, you may begin to see skin discoloration on the face, neck, and chest. These flat marks typically appear light to dark brown in color and can develop in clusters.^II

Dark spots are small areas of skin discoloration, often similar in appearance to freckles. Unlike freckles, however, they won’t fade on their own. Although there are a variety of catalysts that can lead to the development of dark spots on the skin, darker skin tones are more prone to developing discolorations because they naturally produce more melanin. What color they appear as is the result of several factors, including their cause, overall skin tone, and where on the skin the dark spots developed.

If you’ve ever had a stubborn breakout heal, only for a dark spot to appear in its place, then you’re probably familiar with post-acne marks. If not, we’ll give you a brief overview: A post-acne mark, sometimes referred to as post-inflammatory inflammation (PIH), is a type of discoloration that can develop after the skin is damaged from a pimple. The inflammation from the breakout stimulates melanin production, resulting in the appearance of a dark spot, roughly the same size as the original breakout.

Though this kind of discoloration is most common among those with darker complexions, anyone can develop a post-acne mark after a breakout. It may fade on its own, but this process takes time.

Your skincare routine should always begin with cleansing your face to remove impurities that have built up throughout the day. To cleanse your skin, we recommend reaching for a gentle exfoliating cleanser, such as Clearly Corrective Brightening & Exfoliating Daily Cleanser. This purifying cleanser features volcanic ash-derived pearlstone and helps remove the dead skin cells, dirt, and excess oil that can lead to clogged pores. It also contains salicylic acid and peony extract, for a formula that helps brighten and smooth the appearance of your complexion. Use it daily for softer-feeling, clearer-looking skin.

Kiehl’s Expert Tip: Following a regular skincare routine can help keep your pores looking clean. If you do develop a blemish, don’t pick at it as this can damage your skin: Instead, reach for an anti-acne spot treatment to clear up acne blemishes and allow skin to heal.

As we mentioned above, Clearly Corrective Dark Spot Solution is our go-to recommendation for visibly minimizing discolorations and it is clinically-demonstrated to visibly correct dark spots. In addition to fading the look of discolorations, the best-selling serum helps visibly brighten the complexion over time for more even, radiant-looking skin.

Kiehl’s Expert Tip: You can use Clearly Corrective Dark Spot Solution as an all-over facial serum or as a potent targeted spot treatment for stubborn discolorations on your neck, chest, or hands.

Experts recommend wearing sunscreen with an SPF of at least 15 every day (30, if you’re fair).^III Incorporating a broad-spectrum sunscreen, such as Super Fluid Daily UV Defense 50+, into your daily routine can, if used as directed with other sun protection measures, decrease the risk of early skin aging caused by the sun. This lightweight, non-comedogenic formula contains broad-spectrum sunscreen to help protect your skin from sun damage.

Kiehl’s Expert Tip: In addition to wearing sunscreen every day, follow all expert guidelines for safe sun exposure whenever you spend time outdoors. This includes wearing a wide-brimmed hat and avoiding direct sunlight between 10 a.m. and 2 p.m. whenever possible.
