Waso Koshrice Acne Spot Soothing Treatment Review by a Beauty Writer

In our series test ride, TZR editors and writers test the hottest new beauty products and share their honest reviews. This week, our beauty editor is testing the new Wathen Koshirice acne spot soothing treatment.

For as long as I can remember, I’ve struggled with acne. There have been years where it’s been sporadic and debilitating (hello puberty) and there have been others where it’s less noticeable (thanks to a trick of Accutane that seemed to suppress it, at least for some time). Yet, I still found myself desperately trying to fine-tune my skincare routine in an effort to control acne, redness, and texture issues. Anyone with regular breakouts knows that it’s a very delicate balance between using products that are too harsh (eg, stripping and drying) and using products that don’t seem to do anything. everything. That’s why when I recently discovered Waso’s new Koshirice Acne Treatment, I knew I had to spread the word.

This gentle yet effective spot treatment is part of a wider range from Shiseido’s new sustainable collection. In addition to the tube made of 10% polyethylene derived from sugar cane (which is more durable than plastic packaging), the ingredients are all very transparent. “I like products with very pure and simple ingredients that serve a purpose,” says Dr. James Y. Wang, board-certified dermatologist and founder of Metropolis Dermatology.

About my skin

Try as I would to caress my skin, it will forever be prone to acne. Especially in the weeks leading up to my cycle, I experience red cystic flare-ups along my cheeks and jawline. In the past, I’ve pushed and pushed, only to make it worse, but over the past few years I’ve learned that being kind to my skin and using gentle ingredients is the way to go. Now I want to rehydrate my skin and use products that don’t irritate it. I’ve pretty much avoided acne spot treatments for the past year (because most are notoriously harsh) – until now.

The science behind Koshirice Acne Spot Soothing Treatment

What I found most fascinating about this spot treatment was the unique ingredient list. “Koshihikari rice is one of the famous rice hybrids in Japan,” says Dr. Wang. Waso sources his rice directly from a family farm in Hyōgo Prefecture. “Extracts from this type of rice contain high levels of antioxidants, which can repair and soothe the skin. It also prevents excessive oxidation of sebum, which leads to pimples,” he adds. of the product is Shikuwasa Skin Extract, which is a humectant (meaning it absorbs water) and great for skin conditioning.” Combined with rice extract, this product actively protects the skin from further oxidative damage,” says Dr. Wang.

The third key ingredient, salicylic acid, is a common ingredient found in acne products. “Salicylic acid is a beta-hydroxy acid derived from willow bark that exfoliates and unclogs pores,” says Dr. Wang. The over-the-counter concentration ranges from 0.5% to 2%, and this product contains the mildest concentration, at 0.5%, he explains. “Although salicylic acid may be beneficial for acne, higher concentrations cause irritation,” he warns. “I would consider this a very gentle spot treatment.”

How I Used Koshirice Acne Spot Soothing Treatment

The product itself is a clear, liquid gel. It comes in a tube similar to lip gloss, and a light squeeze will give you more than enough product to saturate a stain. I just use my index or middle finger to dab it on the affected area.

To start, I used it at night as the last step in my skincare routine. Once I saw that it didn’t inflame my skin, I decided to start applying in the morning too – again as the last step after SPF. With harsher formulas, my skin starts to flake; however, since this one contains a low amount of salicylic acid (a potent BHA), I quickly worked up to twice a day without issue.

My results with Koshirice Acne Spot Soothing Treatment

Since using the treatment regularly for a month I have noticed a significant difference in the overall texture of my skin – my complexion is smoother and when blemishes appear I am able to treat them before they become massive. And because the formula is non-irritating, I can use it daily to treat breakouts if I need to. One of the biggest benefits I notice is a drastic reduction in redness (which for me always accompanies these breakouts). I can see that it works great for anyone with problematic and sensitive skin.

Is spot treatment worth it?

The Koshirice treatment is, by far, one of the best spot treatments I have tried. But remember, this is not an instant formula. The only products that do anything like this are those that are too loaded with high concentrations of drying ingredients. It takes time (usually a few days) for this product to minimize blemishes so you can regain smooth, glowing skin – no irritation in sight.
