The 10 best brightening serums to lighten dark spots, reviewed


I don’t think I’m the only one who has had hot skin this winter. Although my fair complexion tends to get very dry from December to March, I don’t usually see much other activity. Not so this year. I’ve had my eczema scars jump from my hands to my cheekbones, and a constellation of baby rashes is now permanently ingrained on my right jaw and cheek. It took weeks of slathering on prescription creams and targeted treatments (and a few soothing facials) to get my skin back to neutral, and while we still have a few small pimples and bad patches to deal with, I’m now left with the remnants of my best-performing winter skin. That means hyperpigmentation, and more, which is where my list of lightening serums comes into play.

In case you’re not familiar, post-inflammatory hyperpigmentation is a type of discoloration that occurs after skin damage such as acne, eczema, or trauma (such as picking at a pimple). Basically, it’s a deposit of extra melanin, the pigment that causes your skin color, wherever your skin moves. And although the mechanism between skin damage and your melanocytes going into overdrive is complex and a bit long-winded, what you really need to know is that making those dark marks disappear (at least faster than they will naturally) takes the main ingredients and a lot of patience. In other words, nothing will happen overnight, but my tried and tested list of lightening products will help reduce unwanted pigmentation and leave your complexion clear, radiant, and ready for spring.
