What Is It:

What’s the key to unlocking the secret to a brilliant glow? Su:m37 Secret Essence and its all-natural fermentation process to revitalize your skin and restore its youthful glow.
Su:m37’s secret is fermentation. Su:m37 Secret Essence uses an all natural fermentation process to reveal the most potent form of all their fermented ingredients, which include heavy hitters such as ginseng root ferment filtrate, barley seed ferment, and soybean ferment filtrate. This deep, richly hydrating essence boasts over 80 plant extracts to provide your skin with much needed nutrition delivered in an elegant, nature-derived experience.
Su:m37 Secret Essence is a longtime fan favorite thanks to the gorgeous glow and deep hydration it never fails to provide. Skin is revitalized, leaving you with a brighter tone and an ethereal glowing complexion. Your skin will look younger, firmer, and downright dazzling.
When someone asks what your secret is, tell them Su:m37 — or don’t; your secret’s safe with us.

Our insight:

With a lightweight yet viscousy texture that is never sticky, this essence feels so soothing and nourishing on the skin, you can practically see it infusing your skin with a youthful glow. It’s also a wonderful post-acid treatment as it’s extra soothing while the fermented ingredients help revitalize your new emerging skin cells!
This is what dailyvanity has to say:

“If you, like me, enjoy lightweight products that feels refreshing, this product will be a hit for you. The texture of the Secret Essence feels like water and has one of the best absorption I’ve seen among the products I’ve ever tried. “I also enjoy the subtle scent of lavender in the product, which helps calm me down in the morning before I begin a busy day, and soothe my senses in the evening before I head to bed. Think of it as a form of aromatherapy! “The result of the su:m37˚ Secret Essence may be gradual, but definitely obvious. The one change that stood out to me most was how hydrated my skin became. It feels firmer, more bouncy, and very smooth to touch. Most importantly, my complexion also looked more radiant over time.”

I thought this was massively overpriced for a first essence. You get a lot of product, which I am diligently using twice a day, but it doesn't really do much for my skin. To be fair, most first essences have that effect (or I suppose lack of effect) on me, save for the Naruko La Creme Miracle Essence. However, most first essences aren't nearly $100! You're definitely buying the packaging and not the product in this case. After I finish my bottle up, I'm going back to my Naruko first essence instead.


Just started using this 2 weeks ago and I like it. It's my first time using essence so I don't have anything to compare to. However, it does seem to provide that clean and moisturized feeling, which is my goal. Too early to tell but I hope it will give me that glow.


This smells heavenly. I got this during the beauty tap deal because I ran out of Missha first treatment essence moist. Personally I don't think this is holy grail status for me. I've used sk-ii FTE and that is holy grail. This one feels nice, there is a slip feel to it. But I didn't get the clear fresh plumpness that I get with sk-ii. I think I'll give this to my mom to try. I noticed that it caused some bumps under my eyebrows, close to my eye lid. When I stopped using it, it went away. Might be... Read more


HOLY GRAIL essence for mature (age 50+), dry and dehydrated skin. I bought this for my mother to use. It effectively brightens, evens out skin tone and tightens the skin. Other products layer onto this PERFECTLY. It's crazy how much 1 skincare item makes a difference.... Will be repurchasing this for life!


I love this essence!!! I've been using this one almost 5 year!!!


ferments are my JAM. This essence always leaves my skin super hydrated and hella glowy. Holy grail status!


I seriously love this essence. It's so bouncy and substantial without feeling sticky AT ALL. It layers gorgeously with other serums and it just makes me feel like I'm treating my skin to something truly luxurious. I'm weeping as I see my bottle get closer and closer to disappearing. If it ever goes on sale, I'm buying it in bulk!!!


Now's your chance! How is the scent on it?


It has a botanical scent that is a touch perfume-y, but nothing off-putting. I like to think of it as "high-end herb-y," haha. Just added to cart!


I feel like "high-end herb-y" is the entirety of high end K beauty lol
