This product adapts well to the skin's natural state, which is a great feature.

The packaging is a bit bulky compared to the actual product volume.

A serum that excels in its repairing function, revitalizing the skin's inherent energy.
After trying a sample and loving it, I ended up purchasing it for myself and even gifting it to others. Personally, I find it just as wonderful as the Secret Essence.
It's gentle on the skin, provides adequate hydration, and has a mild fragrance - I'm very satisfied.
I appreciate that it comes in different sizes, 30ml and 50ml.
Among SU:M37° products, it's reasonably priced, which is another plus.

마이크로액티브 리페어 세럼

Try using this as a base layer, paired with essences or ampoules that target specific skin concerns you feel are lacking in your routine.

I found myself wondering if this is truly an essence.
Its effects weren't particularly noticeable.
While it combines well with other products, the lightweight feel and lack of noticeable effects post-absorption led me to layer additional functional essences.

The heavy, opaque glass packaging makes it difficult to gauge how much product is left.
It seems to run out quickly, so you might need to stock up in advance.

* The fragrance is lovely. A subtle, natural floral scent that lifts my mood.
* It has a slightly viscous, thin, beige-colored texture.
While it doesn't absorb instantly, it applies smoothly and feels moisturizing. After absorption, skin feels softer.
* Post-absorption, it layers well with other functional essences without pilling, and pairs nicely with any product.
* Suitable for use across all seasons and skin types without issue.

I tried this as a sample and didn't find any particular drawbacks. In fact, I felt it was more nourishing than SU:M37's basic essence, which I appreciated.

I love the subtle, not overpowering fragrance. The serum has a slightly runny, viscous texture and provides ample nourishment, hydration, and richness. It applies smoothly, absorbs quickly, and feels incredibly gentle with no irritation. When used with the matching cream from the same line, it banishes dryness and leaves my skin feeling wonderfully firm and elastic.

I was shocked by the number of potentially irritating ingredients. Fortunately, it didn't cause any blemishes.

I thought the thin consistency might not be very moisturizing, but I was pleasantly surprised by how hydrating and silky it felt on my skin.

It can be a bit drying, so if you have dry skin, make sure to follow up with a moisturizer for extra hydration.

I love how it applies smoothly with just the right amount of moisture, not too oily. It makes my skin texture feel soft, smooth, and hydrated.

There are many gentle products out there, so I don't see a compelling reason to specifically choose Micro Active.

I tried the 50ml and found it to be a nicely moisturizing, generally pleasant serum. It didn't cause any blemishes and seemed suitable for all skin types - in other words, it was gentle but didn't have any standout features. The slight viscosity wasn't to my liking, so I gave it to my mom who enjoyed its softness and hydration. The Micro Active line seems quite gentle, so it might be great for those with super sensitive skin.

The only downside seems to be the price. It's quite expensive for the amount you get.

Even with my super sensitive skin, I'm using this without any irritation. I love how it has just the right balance of hydration and richness.

While I personally liked the scent, it might be a matter of personal preference. Be mindful of the ingredients!

The absorption and application are both excellent! It's packed with the perfect balance of oil and moisture, making it ideal for dry skin types. I absolutely love it! At some point, the Torriden Hyaluronic Acid Ampoule became my gold standard, but for those with dry skin, this might be even better. It has a nice viscosity - I actually prefer it a bit more fluid, which works great for me!

I bought this as part of a set with the Secret Essence. Compared to how amazing the Secret Essence is, this serum felt rather ordinary for its price point.

It has a nice, firm texture and absorbs well. I also love the scent - it's right up my alley. I thought it might be heavy since it's a repair serum, but the consistency is just right. It's light enough to use during the day, and there's no pilling when I apply sunscreen over it.

It works even better when used with the powder wash and cream from the same line. The powder wash leaves your skin feeling super soft, and while the serum alone might feel a bit drying, applying the cream afterwards helps balance things out. I don't usually buy the serum on its own. I tend to purchase it in a set, or when there's at least a 15% discount, or when there's a gratis offer. Besides individual products, they also sell curated sets, so it's worth looking into those. I usually buy from the SU:M37 official store or their official Naver Smart Store. Olive Young also runs promotions on these products from time to time.

It seems a bit pricey without a discount. But honestly, I rarely buy it without a discount, so I guess that's not really a drawback. To be frank, I can't find any real downsides. Though even with a discount, it still feels a bit expensive.

I've been using this morning and night, and I really like it. My skin has become noticeably softer.

It's supposed to be a calming serum, but I didn't really feel any soothing effects. I probably wouldn't spend my own money on this.

The only positive thing I can say is that it didn't cause any blemishes after application... I guess that's something?
