Charlotte Cho of SokoGlam Shares Her Favorite Skincare Ingredients

Have you met Charlotte Cho yet? She’s kind of a big deal. This summer alone, she’s had features on Elle, Lucky, and Allure, and she also happens to be the owner of the magnificently curated US-based Korean cosmetics shop, SokoGlam. I’ve had the pleasure of getting to know her over the past few months, and I love how open and knowledgeable she is about the latest Korean skincare lines. She’s currently working toward her esthetician license as well, so I was ecstatic when she agreed to do a guest post about her favorite skincare ingredients. Here’s what Charlotte had to share:

SokoGlam Charlotte Cho's Favorite Skincare Ingredients

Before living in Korea, I remember perusing a beauty counter at Nordstroms and purchasing a bottle of toner—not really knowing what I was doing. I used it for about five days before my skin started breaking out. Worst yet, as soon as my skin met the toner, it stung and resulted in an irritatingly tight, dry feeling.

To my surprise, when I tested out toner products while in Korea, I was met with the opposite effect: extremely moisturizing, extremely calming, and the added bonus of no alcohol as an ingredient. That exact moment was when I got serious about Korean skincare ingredients.

In a general sense, Korean skincare may seem like it’s too “adventurous” and all over the map with their ingredients—snail extract, anyone?—but after years of being immersed in the Korean skincare market, I now know that there’s a method to the apparent madness. No, they don’t just try all the ingredients under the sun to “see what sticks!” Korean women have the notorious reputation of being the pickiest skincare consumers out there. Also, high quality and high standards have encouraged a wave of even the most sought-after products to be affordable and accessible to the masses.

The following are my five favorite on-the-cusp skincare ingredients to seek out in Korean beauty products:


1.    Green Tea Extract (Camellia Sinensis)

We already know green tea as a healthy beverage—but did you know green tea extract is also great for your skin? While drinking the tea can reduce stress, lower blood pressure and boost immune systems, green tea also contains natural antioxidants called polyphenols that help ward against even skin cancer. Green tea extract can also soothe irritated skin, help clear acne, and help with dark circles under eyes. Convinced yet?

My favorite product containing green tea extract is the Skin 79+ SuperBeblesh Balm Triple Functions BB cream. I often get emails from people who have shared stories about how much their skin has actually improved while wearing Skin 79+. That’s the major difference between Korean BB creams and non-Korean—actual improvement of overall skin condition. This BB cream not only covers imperfections, it moisturizes, treats and hydrates. It’s a bonafide Korean beauty cult favorite for a reason.


2.    Snail Mucin

Ah, snail mucin. As in: snail extract. As in: snail slime. Our mollusk friends use the stuff to help heal their bodies as they squish along rough terrain. After Chilean snail farmers (yes, that’s a thing) discovered their hands were softer and even healed quickly after handling snails, a new beauty revolution was born. And in case you’re wondering: No, the snails are not harmed in any way.

My favorite product of the moment with snail mucin is from Benton. The Snail Bee High Content Skin/Toner hydrates and preps your skin to absorb the next steps in your skincare regimen. The toner contains green tea (which hydrates, brightens), snail mucin (firms skin, encourages cell regeneration, replenishes moisture), and bee venom (which features anti-inflammatory, anti-bacterial, anti-viral properties). And if you’re looking for a snail cream, this Missha Cell Renew snail cream is highly recommended. It comes with a snail sleeping mask too for extra hydration at night.

While, honestly, I haven’t had too much experience with bee venom as an ingredient other than the Benton line, I’ll be sure to provide updates on what I think as I use other bee venom products.

3.    Fermented Yeast Concentrate

This one is probably still unfamiliar to many. Fermented yeast concentrate, also known as fissione, is easily absorbed into skin. It basically allows the skin’s outer layer to be renewed faster since the formula works on a cellular level, leaving you with that glowy and dewy skin that so many Korean women seem to have.

Missha’s First Treatment Essence contains a whooping 80% fermented yeast concentrate (official ingredient name: Saccharomycopsis Ferment Filtrate), and also vitamin B3 to increase skin elasticity and revitalize skin tone and texture. And the incredibly refreshing First Treatment Essence Mist can be used before makeup application or any time throughout the day—which I always, always carry with me. Many Koreans believe essence to be the most important step in skincare routine, and so do I. I remember to use this product every morning and every night after toner.


4.    Bamboo Sap (Bambusa Vulgaris)

The benefits of fermented bamboo extract are more than noteworthy. Known for its unparalleled ability to provide instant, long-term hydration, bamboo sap features a ton of anti-inflammatory abilities. When a formula substitutes oil for water in their product, I definitely approve. When a formula substitutes water for bamboo sap, I’m all over it!

The Waterfull Rebalancing Gel Lotion from SU:M37 moisturizes skin and increases the density of moisture using four key fermented ingredients: Bamboo water (which contains beneficial amino acids), red clover flower extract (promotes skin vitality), hibiscus flower extract (maintains moisture), and gold-silver flower (minimizes pores). I think the reason why I love SU:M37 products is because they replace the use of water as an ingredient completely—preventing formula dilution and ensuring effectiveness as a whole. The entire SU:M37 line has no artificial fragrances, colors, or preservatives.

Another really fantastic product line worth checking out that contains fermented bamboo extract is AmorePacific’s Moisture Bound.

5. Hyaluronic Acid

I am in the process of getting my esthetician license and I’ve been diving deep into different ingredients and the chemistry/physiology of skin. My new favorite ingredient is hyaluronic acid, which is a humectant that binds moisture to the epidermis (the outer layer of the skin). I have severely dehydrated skin so I make sure to drink a lot of water but because water actually goes to your skin last (vital organs get first dibs, understandably) it’s important to apply moisturizing ingredients topically. This ingredient actually prevents moisture loss AND increases moisture content in the skin. My favorite product right now that has hyaluronic acid is the Lioele V-Line Sleeping Pack.

Now, let’s get real here: Will these ingredients create a miracle solution for your skin, banishing wrinkles or clearing acne overnight? Nope. But what it can do is brighten or pacify inflamed skin, helping eventually fade acne over time, and, yes, actually improving your overall skin condition.

While staying vigilant about ingredients is an important aspect of skincare, it’s equally important to maintain the proper mindset about skincare as well. In Korea, taking care of your skin is an entire culture—an entire lifestyle if you will.

Expecting a particular “miracle product” to save your skin single-handedly is like depending on an unhealthy crash diet. Changing your “skincare lifestyle” as a whole by taking preventative measures is what’s really going to result in great skin over time. Proper cleansing, moisturizing, and the daily application of SPF are the big, big takeaways here. Maintain your skincare routine and you’ll be rewarded with brighter, radiating skin that’s here to stay.

    Sokoglam’s customer service is awesome. I had a small issue and they took care of it immediately. Love this article.

  2. cassie

    Where can I find that lace eye mask?

  3. Bianca

    Hopefully, I can try her line 🙂

    Charlotte is a real beauty! And what a cute dog she has!

    It would be useful to read her tips and experience on Korean sunscreens. Is it a Missha All Around Sun Milk on the back of the 2nd pic? Does she use it on face?

  5. Love this post SO hard! Really great to learn about some of the key ingredients in Korean Skincare, which is one of the reasons why I LOVE your blog Kerry! Definitely a few items mentioned here that I have yet to try but are currently on my next haul list.

    Just snagged a travel version of the Amore Pacific moisture bound from Amazon & can’t wait to discover all about the awesome benefits of bamboo sap! xo

    • Kerry

      Hey Tiffany! I must know – what’s on your next haul list?

      • Kerry dahlin! I’m soooooo glad you asked! Items on their way to me now: Amore Pacific Moisture Bound & the ARITAUM Baby Face Mist in Vitamin C, also snagged some more Benton Steam Cream. On my haul month for Sept are: Missha First Treatment Essence Mist, Skinfood strawberry & Black sugar mask, Mizon Starfish Cream, Too Cool For School McGirly Eye masks, a BHA from Paula’s Choice, and the SKII essence! May not get all of them in Sept, but these are what I have my eye on for my next big Korean skincare haul.

        • Kerry

          That sounds like an amazing haul, Tiffany! You’ll have to let me know what you think of the AP Moisture Bound! 🙂

          • Jayanthi Kanderi

            Kerry… I am using the AP moisture bound sleep mask. Its amazing. Skin feels plump and super soft in the AM.

    • Bamboo sap is an all-natural way of binding moisture to the skin 🙂

      • Ooooh! Can’t wait to experience it. I totally snagged some travel size Amore Pacific after I saw your IG post. Didn’t know they made them & it’s a great way to try something before splurging on the full size. Thanks Charlotte!

  6. Superb article! I am one of those who think Korean/Asian skincare is all over the place and that there are so many unknown ingredients. This is a great guide to start with! I think I am definitely looking into adding snail extract in my skincare… 😉

  7. Great interview! I’m very intrigued by bamboo sap. I think that’s the only ingredient on this list that I haven’t tried or at least read about extensively. Totally random but her dog (assuming that’s her dog in the picture above) looks a lot like the ones I had growing up!

  8. Kalea

    I’m a recent convert to Korean skincare, and Charlotte and sokoglam have helped me learn so much! Anytime she’s mentioned in an article, I have to make sure to check it out! Thank you for the post. 🙂

    Hi Kerry, I remember in one post you mentioned about your doubt as to whether cetearyl acohol contributed to your breakouts. Also, you recommended the Hada Labo hyaluronic acid milk for morning uses which I’m really keen on trying out (the Jap formula). I’m just concerned since the product includes cetearyl acohol, whether my acne prone skin will react negatively 🙁 Any advice? Thanks so much!

    • Kerry

      Hi Camille! That’s hard to say – have you had any issues with Cetearyl Alcohol in the past? I think that would be your best indicator. 😀 My own relationship with Cetearyl Alcohol is complicated – for me, I think my ingredient sensitivities as far as acne goes are more more dependent on the overall product formulation than on the ingredient itself.

    What an awesome post! I do sometimes find myself wishing that western culture was as into skincare as eastern cultures are! Perhaps then I wouldn’t be looked at like I’m crazy when I’m covering up in 90 degree weather and using 4-5 products on my skin at a time! >_<

    Kerry I did have a unrelated question for you regarding the OST serum that you've raved about. I've been using mine for a little over a month and find that it has started to change color a tad bit. Does a slight change mean it is completely useless? It isn't the bright orange that I've seen in other expired OST serums. Also, how long do you find a bottle lasts you? As in, how much do you apply at one time and how many weeks, months does it last until you use it up/it oxidizes? Thanks for the help!
    [Btw incase you were wondering, it totally helps me with pores and blackheads when used in conjunction with a 10% glycolic treatment every other night! I can visibly see my large pores have shrunk and my blackheads kind of become shallow and fall off? I'm not sure if it makes sense lol.]

    Hi Kerry 🙂 What do you think about IS Clinical Warming Honey Cleanser? It’s ingredients are Glycerin, Mel (Honey) [Miel], Myristic Acid, Olive Oil PEG-7 Esters, Polyglyceryl-10 Behenate/Eicosadioate, Polysorbate 80, Sodium Lauryl Sulfoacetate, Papain, Camellia Sinensis Leaf Extract, Triethanolamine, 1,2-Hexanediol, Caprylyl Glycol.
    And my inner stalker would love to see your face mask collection 😉

  12. Oh gosh. I keep seeing your blog (skin & tonics) around but never get to reading. I frikkin love how detailed you get about ingredients! MOAR PLS.

    Also, fabulous job on interviewing Charlotte. This article is fantastic. Reading everything from now on 🙂
