COSRX Acne Pimple Master Patch

COSRX Acne Pimple Master Patch (24 patches, $6) is a waterproof acne treatment patch that cleanses pores and reduces pimples, redness and inflammation. The uniquely developed hydrocolloid material effectively extracts impurities from the affected area, creating a moist environment that makes the healing process faster. The Acne Pimple Master Patch also acts as a barrier against bacteria, preventing secondary infection. COSRX Acne Pimple Master Patch is easy and hygienic to use as it comes in a resealable pouch and sterilized double packaging to keep it sanitary. The Acne Pimple Master Match is ideal for those with acne-prone skin and can be used on the face and body.

COSRX Acne Pimple Master Patch is designed as a hydrocolloid bandage, a medical-grade material used to support skin healing that absorbs impurities and protects blemishes from outside irritants. You are probably familiar with hydrocolloid bandages – gel-textured bandages that keep you from popping blisters and help them heal faster but hydrocolloid bandages designed specifically for acne absorb fluid from the pimple without drying out the skin. According to Elizabeth Tanzi, an associate clinical professor in the department of dermatology at the George Washington Medical Center, “hydrocolloid bandages have the added benefit of blocking you from picking the pimple […which] increases the inflammation and can slow the healing process down”. However, if you have sensitive skin, you may want to read this article from the Zoe Report about hydrocolloid formulas before using this product.

The COSRX Acne Pimple Master Patch sticks well very to skin due to the cellulose gum that helps form the elastic covering and its sticky adhesive. Additionally, liquid paraffin, which is a highly refined mineral oil used in cosmetics and medicine, acts as an occlusive emollient that forms a film on the skin that acts as a water resistant barrier. The film formed by the liquid paraffin also helps to prevent the evaporation of the skin’s natural moisture. In other words, the Acne Pimple Master Patches not only pulls the yucky stuff out of the pimple but is also protects the skin and prevents it from drying out.

My Take

I purchased the CORSX Acne Pimple Master Patch after reading many positive reviews on the Dermstore website. The patches are arranged on plastic cards inside a white resealable packet. The patches were clear and thin and came in a variety of sizes, allowing the user to find the right size to cover the problem area. I used the CORSX as needed and only at night, to help get rid of zits on my face. I used the COSRX patch after cleansing and toning and did not apply any other skincare product to the area covered by the patch on the nights when I used it. The patch went on clear and although my face tends to get oily while I sleep, the patch never fell off and I always had to peel them off in the morning. After 6-8 hours of wearing the patch, the thin almost transparent patch transformed into an off-white, thick disc that seemed to have sucked out all the bacteria and impurities from the zit leaving smooth, pimple-free skin in its wake.

There are so many things I love about the COSRX Acne Pimple Master Patch. First, I loved how well it worked! I wasn’t expecting much for $6 but in terms of value for money, the COSRX Acne Pimple Master Patch is by far the best skincare purchase I have ever made and I think I will always have a sheet of these patches in my bathroom drawer for skincare emergences. Relatedly, the Acne Pimple Master Patch have an excellent value for money and are far more economical than other cream or gel-based acne spot treatments and the Acne Pimple Master Patch has the added benefit of protecting the pimple as it works its magic. Also, I love how inconspicuous it is, in fact, if I were brave enough, I could even wear it during the day, but I would be too self-conscious and worried that someone would notice the patch and ask me about it. I also loved how adhesive it was, so I never had to worry about hunting for it in the morning among the pillows and sheets because it came off during the night

One critique I have of the CORSX Acne Pimple Master Patch is that it doesn’t get rid of all kinds of pimples. I have found it works best for surface-level zits, particularly white heads that many people with mild to moderate acne get but the patch is less effective against the deeper whiteheads and black heads that those with cystic acne usually get. Another critique is that even for the pimples that the CORSX Acne Pimple Master Patch does work on, the patch doesn’t always completely get rid of the pimple. Sometimes, the Acne Pimple Master Patch just reduces the size of the zit (albeit drastically) and/or the visible whitehead but not the roots of the zit.

Overall, I whole heartedly recommend COSRX Acne Pimple Master Patch for those who suffer from occasional whiteheads and do not want to commit to a full time, multistep acne regimen. These patches are not a long-term solution to acne because they are a reactive, rather than a preventive, measure against acne. Nevertheless, the fact that these patches work so quickly and give as close to immediate results as one can get while using an over counter acne products, I think the COSRX acne patches are definitely worth a try!
