Dark siko and tuhod are two of the most common beauty concerns that many Pinays have.
On August 31 at the Cosmopolitan Beauty Con 2019, Dra. Vicki Belo explained that it's completely normal for one's knees and elbows to be darker than the rest of the body as these areas are prone to stretching, bending, and rubbing. Hence, all that "friction" naturally darken these parts. "Also, if you would notice, the skin on your elbows and knees are more makapal. It's not as [thin] as your skin on the rest of your thigh. And if you look at it microscopically, patong-patong 'yong balat [kaya] minsan nagkakaraon ng kalyo," says Vicki. "You need to exfoliate."
Many Pinays would normally rub calamansi on their elbows or scrub off the rough spots on their skin with a bimpo or a loofa, but Vicki warns that these classic exfoliating methods can further darken the skin. "[Scrubbing] can ruin your skin," the beauty expert explained. "The loofa, [in particular], is the worst because you leave it in the shower and after a while, there's a lot of bacteria that grows from there. The plastic one is okay but it's also very abrasive. This is why I don't believe in physical scrubbing. I only believe in soaps that naturally exfoliate [the skin.]"
Her recommendation? "A cheap way to brighten your dark areas is to use a papaya kojic soap... The best way to exfoliate, in my opinion, is to use fruit acids,"

Unlike physical exfoliation, acids don't require scrubbing. The chemical exfoliants work to lift off dead cells on their own, naturally revealing a lighter skin. So while the word "acid" may sound harsh, they're arguably gentler.
When using kojic acid soaps, Vicki suggests waiting for two minutes before washing them off of your body. Otherwise, "there's not enough time for the soap's active ingredients to penetrate and remove that dead skin." She adds, "You can exfoliate your knees every day with soap but if you insist using a scrub or a loofa, just do it twice a week. Maximum na 'yun."
