Both blackheads and in-grown hairs are beauty bugbears. When it comes to underground beauty hacks, Reddit is often the place to go, and with summer fast approaching this hack is re-emerging as the go-to solution for ingrown hair.

No-one likes ingrown hairs, especially on sensitive areas such as the bikini line, and women have taken to the Skincare Addiction subreddit to hail their miracle cure –The COSRX BHA Blackhead Power Liquid.

Posting on the subreddit, one user claimed: “I started using is as an after-shave with surprising success! No irritation, ingrown hairs have lessened a fair bit.” 

Another wrote: “I’ve used BHA successfully on ingrowns. You probably just don’t want it too close to any super sensitive parts.”

How does it work?

BHA’s are effective and powerful chemical exfoliants which gently slough away dead skin which clogs pores. They can penetrate skin and unclog pores which may be why Reddit users are hailing it’s ingrown-fighting abilities.

Julia Marinkovich, COSRX UK Representative explains; “BHAs are oil-soluble and can therefore penetrate deep into pores helping to unclog them and remove dead skin, which means they will likely be successful at soothing and clearing the inflamed, irritating clear little bumps left from shaving. However, there is no medical or scientific evidence that it can remove or loosen ingrown hairs.”

More Skin Benefits

The serum contains 4% natural Betaine Salicylate, an exfoliant which not only gets rid of blackheads and sebum inside of the pores, but also prevents sebum turning into blackheads via oxidation, and helps skin rebuild its moisture barrier. The light serum also contains White Willow Bark, which can help to decrease redness and inflammation, as well as Niacinamide and Sodium Hyaluronate, working together to fight acne, brighten, smooth and hydrate dull skin.

COSRX has a huge global cult following and sells out as soon as it is replenished. It has sold out 6 times already in 2022, with consumer demand outweighing supply.
