₩ is the Korean store price; $ is what Olive Young Global lists. They often differ because the pack size or count sold overseas isn't the same — check the size on the listing before you buy.
Not a cart — nothing is sold here. I check it against what you already use: clashing actives, doubling up, and morning vs night.

About this product
Worth the hype? Partly. SUM37's Secret Essence has a genuinely nice, silky texture and the fermented ingredients do deliver real hydration, which explains a chunk of its cult following — but it's a fragranced formula with alcohol in the mix, so it's less of a gentle, do-no-harm essence than some reviews suggest. The refill set is a smart way to get more product for the price if you already like the formula.
Best for combination skin that tolerates fragrance and wants a hydrating, cosmetically elegant essence layer — not the go-to pick if you're avoiding fragrance or alcohol.
Pat a few drops onto cleansed, toned skin and let it absorb before your next step.
What reviewers say
I'll be straight with you: this essence feels luxurious going on, and the fermentation-forward formula is genuinely hydrating, but it's also fragranced and contains alcohol, so it's not the barrier-repair miracle the marketing implies. If your skin tolerates fragrance fine, it's a pleasant, silky step — just don't expect it to replace your actives.
Asked which skin it worked for, 52% of reviewers picked combination (dry 41%, oily 6%).
81% called it gentle on their skin.
These add up to 100 — it's which answer people chose, not a score out of 100. It tells you who liked it, which isn't the same as what will suit you.
