A serum that can do it all? Yes, please! You might have heard of all the viral products by the K-Beauty brand Mixsoon (like the Bean Essence with over 9K reviews), but we guarantee you haven't tried this hidden gem.

The Master Serum has only 500 reviews (for now), but users swear by it for its lightweight texture and soothing ingredients. People with sensitive skin say it has completely transformed their skin—for the better. It promises to relax your skin with its powerful hydrating ingredients and strengthen your skin barrier. 

It's formulated to be lightweight enough for quick absorption into the skin and addresses multiple skin concerns. The serum creates a protective moisture barrier that helps retain moisture and hydration while improving your skin's texture. 

It's not just reviewers who love it, though. This beauty writer is obsessed with it, too. When I was struggling with a skin flare-up, caused by stress and overexfoliation, Mixsoon's master serum is one of the only products I go back to, because I know it will give my skin the deep hydration it craves. 

The best part of finding these hidden gems is that, more often than not, they're incredibly affordable. And this serum is no exception with its $20 price tag. So, if you're in the market for a new hydrating, safe-for-sensitive-skin product that won't break the bank, keep scrolling!

Mixsoon Master Serum Moisturizing Serum

This serum is formulated with centella asiatica, bifida ferment extract, and panthenol to help collagen production, strengthen the skin barrier, and improve hydration. 

What Shoppers Are Saying About Mixsoon's Master Serum:

"The serum itself is great! It's very hydrating, calming, and gentle on my skin. So far, I really like it. My skin has been very irritated and inflamed because I've been breaking out a lot lately. So I got this hoping it'd help my skin barrier. The morning after I first used this, my skin felt so much less irritated, and it was the first time in weeks that I didn't wake up with a new pimple or two. So it seemed to really help calm the active breakout I was having, and really soothed the skin irritation that was caused by it. My skin feels better each day I use it, it feels like it's finally healing."

"Since discovering Mixsoon's Master Serum, my skin has undergone an amazing transformation.
This moisturizing serum is truly a Korean gem, and I can understand why Mixsoon is synonymous with quality in its products. The first thing I noticed is how light and pleasant it is to apply; it absorbs quickly without leaving a sticky feeling. But the most impressive part is the results: my skin feels incredibly hydrated, soft, and looks much healthier."

"Absolutely love this brand and this oil. It’s light and smells good. It doesn’t irritate the skin. I use this not only on myself, but also on my 7 and 3-year-olds. My 3-year-old deals with eczema, and this helps keep her face moisturized."

"My favorite serum for my dry skin with rosacea. So convenient to use when I don’t have time to do many steps in Korean skincare. Serum, moisturizer, sunscreen, and some concealer, and I’m good to go."
