the science

It’s not exactly a short ingredient list although not unexpected given the product boasts over 80 fermented botanical extracts. I counted 115 ingredients in total.
Fermentation increases the potency of ingredients by breaking them down into a smaller molecular size for easier absorption into the skin. Fermentation adds microorganisms that release enzymes to achieve this. It also introduces amino acids, organic acids and antioxidants to optimise product benefits and nutrition. Furthermore, as fermentation neutralises any toxins that may exist within the raw ingredients, it also reduces the risk of skin irritation.
Extracts are individually fermented in cedar barrels in a controlled, consistent environment at the optimum humidity and temperature of 37˚C (hence the 37˚ in the brand name) for 365 days. The formula contains an exclusively patented Ferulic Acid which helps activate the star ingredient, Cytosis®, made of these 80+ fermented botanical extracts. Cytosis® is able to rebuild the foundation of good skin and strengthen it against external pollutants and aggressors through its enriched antioxidant properties. Ferulic Acid is a potent antioxidant which makes it extremely helpful against ageing.

So, let’s have a look at a few other ingredients in the formulation. Firstly, water would make up the vast majority of the volume, particularly noted since the fourth ingredient on the list Meadowsweet Extract has a recommended concentration of between 5-10% in skin care products. This ingredient is a soothing herb, useful for treating irritated skin due to its anti-inflammatory, toning and astringent properties. Represented at significant concentrations are Dipropylene Glycol, a humectant that helps to draw moisture to the skin while identified as an emollient and helping to retain moisture is Glycereth-26.
There are a few humectants (Glycerin, Methyl Gluceth-20, Betaine) added for hydration and way down past all the botanical extracts you’ll also find Niacinamide, Sodium Hyaluronate, Lipids, Cetearyl Alcohol and Ceramides. As great as these may be, their concentrations are very low and unlikely to have much impact on the skin. Rounding off the formulation are essential oils added for fragrance and preservative function to increase the shelf life of the product, all of which have the potential to be sensitizing.

the performance

The most popular, highest selling signature product for the brand, the Su:m37° Secret Essence is more than famous in the Korean skincare world. It is iconic. Due to the high concentration of fermented extracts, it is often compared to luxurious Asian products such as the SK-II Facial Treatment Essence. Does is live up to the hype?
Su:m37° Secret Essence Claims
Firstly, the presentation is luxe, synonymous with the high end brand. The heavy bottle with its sleek appearance, elegant labeling and red jewel topped gold lid ooze sophistication. The frosted glass finish implies the product is not light sensitive. It is simply a pleasure to have this essence sitting on the bathroom counter. The dropper mechanism works well, dispensing the required few drops per application easily and with low risk of contamination.
The liquid is very lightweight but more viscous than water. It is quite a typical texture for a product of its nature. It has a distinct herb-like citrus fragrance which is not unexpected given the high number of botanical extracts and the several citrus essential oils. The scent certainly dissipates with absorption which is fast. Once applied to the skin, the essence simply sinks in without any trace of residue, stickiness or tackiness. Only one layer is required and as directed, should be patted in gently for at least 10 seconds. It’s quite extraordinary how satisfying it is to pat into the skin because of its slight cooling sensation and its lightweight viscosity.
In trialing this product, I chose to use it as intended, after toner. After a few weeks of twice daily use, I observed some improvement in my skin texture, although it was not dramatic. I get a much more rapid improvement in softness and smoothness from a propolis product like the Skinfood Royal Honey Propolis or Dr. Ceuracle Vita-Propolis Ampoule. My skin is certainly somewhat softer and smoother after continued use however, the texture impact took me a few weeks to truly appreciate.
The hydration effect on the other hand was far more obvious and plumpness quickly observed. I used this in place of all other hydrating products excluding a toner and cream to gauge its ability to return and retain moisture to the skin. During the trial, I was incorporating the Dr Ceuracle Grow Hyal B5 at the toner step. The Su:m37° Secret Essence was able to hydrate my skin very effectively without any additional serum.
Finally, with respect to the price… well, after some consideration, I believe it is worth it, if you find it at a discounted rate. I bought mine for USD$70. A good hydrating serum costs upwards of USD$30 for a 30ml bottle. This product delivers similar benefits to such a product even though it is an essence. Using this arithmetic, USD$100 for a 100ml luxury essence seems acceptable while USD$70 almost makes it appear affordable. If you want it bad enough, you’ll find a justification right? And I really wanted to try this cult product!
The only unfortunate thing is that you commit to 100ml without any certainty that you’ll actually like it. Smaller volume options that I’m aware of come in special Su:m37° sets which often include a trial sized (30ml) bottle. The advantage with these is that they additionally give you the opportunity to try several other trial sized items from the brand.
Su:m37° Secret Essence
Due to its lightweight consistency and high absorbancy, I would suggest that the Su:m37° Secret Essence is suitable for all skin types. All need hydrating and this will achieve that in a sophisticated way. Of course, those sensitive to botanical derivatives need to be overly cautious since the formula boasts over 80 natural extracts as well as several essential oils.

the conclusion

This essence provided me a boost in hydration while also adding a softening and smoothing effect to my skin. It is a luxurious step in my routine that I thoroughly enjoy. The 100ml bottle will last several months. Those into Korean beauty who haven’t tried it, really should. It retains an iconic status because of its efficacy and elegance. It’s a beautiful product, although not extraordinary.
