환절기때 쓰는제품입니다. 토너쓰고 조금 다 흡수되고 바르는 제품입니다. 촉촉하고 속건조 잡아주는 거라 추가 로션 크림은 발라야해요

용량이 작고 가격이 좀 사악하죠. 트러블 없고 모든 피부에 맞는 것 같아요. 대신 피부 안 좋을땐 확실히 좋은 제품

속건조가 많아서 샀는데 너무 좋아요. 묽은 물 제형이라 물처럼 흐르는데, 흡수 좋고 산뜻해요.

시크릿 에센스

This review highlights the product's excellent hydrating properties, praising its moisturizing effects. However, the user expresses concern about the cost, suggesting that purchasing in larger quantities might be more economical. The contrast between the product's performance and its price point is evident in this feedback.

The price is a bit steep, so you need to buy in bulk to make it worthwhile. That's a bit of a letdown.

It's so hydrating! Moist, dewy, hydrated, and supple. Absolutely fantastic!

For those with combination dehydrated skin, you might want to layer this with other hydrating products for best results. While it absorbs well and doesn't feel sticky, it may not provide enough intense hydration for those battling significant deep dryness on its own.

As someone with deep dryness, I found this serum alone wasn't quite enough at the ampoule stage. The packaging also makes it tricky to control how much product you dispense.
Considering the price point, I'm not convinced it's irreplaceable - there are likely other products out there that could serve a similar purpose.

The essence-type formula is great for refining skin texture with its hydrating properties.
It has a lightweight yet concentrated consistency that absorbs quickly without leaving any sticky residue, which I prefer over heavier formulations.

The main drawback is the high price point. As it's a daily-use product, the cost can be quite burdensome.

Within just 2-3 days of use, my skin texture became noticeably smoother. It absorbs well and has a subtle, luxurious scent that made application a pleasure. Overall, it feels effective for managing skin elasticity and radiance. While it's on the pricier side, if you can invest in your skincare routine, this product is definitely worth it.

아쉬운점은 가격밖에 없죠. 가격 조금만 내려주길 ㅠㅠ

제 인생템입니다. 세안직후 바로 바르면 너무 좋아요. 피부속까지 꽉꽉 채워지는 느낌입니다. 기술력이 느껴져요.

I apply this first after cleansing. It's not heavy, so it penetrates the skin nicely.

It feels more like a toner than an essence. Because of that, I don't notice any dramatic effects, but I still apply it as part of my basic skincare routine.

It's lightweight and non-oily, making it comfortable to apply. Especially as the weather starts heating up, it's rare to find something as easy to use as this. You can use it without worrying about blemishes, and it absorbs well into the skin.

At first, I thought applying just this felt like using only toner, so I always followed up with a cream. But once I realized that using this alone doesn't cause deep dryness, it became a product I reach for often.

There's definitely a reason why this product hasn't been discontinued!

For me, SUM37 products are like a soothing balm. When my skin barrier breaks down after using functional or popular products, I always go back to SUM37. It's funny, but SUM37 is the only brand with a set routine that works for me.

It's heavier than before. To put it nicely, it's more hydrating. It's better than the pre-renewal version.

I've tried almost all of SUM37's products, and I started with Secreta instead of Secret Essence as my first step. I tried the renewed version this time, and it feels much smoother.

It's on the pricey side. Apart from the cost, there are absolutely no drawbacks. I'm eagerly awaiting the release of a larger size.

It's incredibly gentle on the skin. No need to worry about blemishes.
Applying a thicker layer yields even better results.

The bottle opening is frustratingly small.
I have to turn it upside down and tap vigorously
just to coax out a single drop.
As a result, I feel like more product ends up on my hands than my face.
While the bottle design is aesthetically pleasing,
it's quite impractical to use.

For those with dry skin,
applying this after toner
banishes that parched feeling.
It's slightly sticky, but
given how dehydrated my skin is,
I actually appreciate that.
The fragrance is also pleasantly subtle.

Absorption is excellent, so you can layer it twice on special occasions without any burden.

The volume control is a bit difficult.
At first, it didn't work well, which was frustrating. But once I got used to it, it's fine.

And above all, the price is ㅠㅠ
As a gift, both the recipient and the giver would probably like it, but to be honest, it's a burden for personal purchase.

It seems like I've been using the product for about 2 weeks.
I've been using only fragrance-free, low-irritation products with good ingredients, but I started using this one as a gift.
First of all, the lovely fragrance is so nice^^
It's a runny, essence-type skin with almost no viscosity.
The slip is good, the absorption is good, and after applying it, my skin feels smooth and energized.
It's moisturizing without being sticky, and the product itself is excellent without any downsides.
Even for my combination skin, it doesn't feel burdensome, so I think it would suit any skin type.

The quantity is too small for the price. The consistency is a bit too thin and runny, which is disappointing.

I've finished one bottle and I'm now using my second. I definitely notice smoother skin texture the next day when I apply makeup, and my makeup goes on better too. It also gives my skin a nice glow. I plan to buy it again when I run out.

It doesn't work. It's just thin and runny. I use it as an essence, but I can't really tell if it's doing anything.

It doesn't seem to have much effect. It's just a light, watery essence. At least the price isn't bad.

I'm satisfied every day just by using a cleanser, toner, the Secret Essence, and a hydrating cream. It works hard to keep my skin happy.

If I had to nitpick, when I first tried it, the watery consistency felt a bit cumbersome, which led me to switch to other products. But what made me rush to buy it again?

The Su:m37° Secret Essence has a peculiar charm. After using it for a while, I switched to something else. But then I found myself thinking, 'Wait a minute...' and ended up repurchasing this essence. It's become my go-to product.
