Consider layering it and try using it together with essence or ampoule products that you feel are lacking in your usual routine.

Is this really an essence??
I couldn't really feel the functionality as much as I thought I would
It pairs well with other products, but the usage feels light and after it's absorbed, I can't really feel the functionality, so I end up applying another functional essence on top
The heavy, opaque glass material makes it hard to know how much to use
There's a bit of a wasteful feeling with the usage, so I have to purchase the product in advance

It has a pleasant aroma. The subtle, natural floral scent is captivating, making me feel good.
The formula has a slightly viscous, pale beige texture. While it doesn't absorb immediately, it applies smoothly and softly, leaving the skin feeling soft and moisturized after absorption.
After absorption, it does not interfere with the application of other functional essences, and it pairs well with any product.
It can be used comfortably regardless of season or skin type.

마이크로액티브 리페어 세럼

The sample I tried did not have any particular shortcomings, and I felt it had more nourishing properties compared to the basic essence of Sulwhasoo, which I found to be positive.

The subtle, unobtrusive fragrance is pleasing to me. It's somewhat like a runny? Viscous serum, and it provides sufficient oiliness along with nourishment and moisture. It applies smoothly, absorbs quickly, and is so gentle that no irritation is felt. When used with the cream from the same line, the dryness disappears, and there is a pleasant sensation of increased firmness.

I was very surprised by the large number of active ingredients. Fortunately, there were no skin issues.

The watery formulation seemed like it would have weak moisturizing properties, but I was pleasantly surprised by how hydrating and soft it felt.

Those with dry skin should definitely apply a cream, as it will make them even more moisturized despite the somewhat dryness.

It applies smoothly with just the right amount of oil, leaving my skin feeling nicely moisturized and soft. My skin texture became smoother and more supple.

There are many mild products, so there doesn't seem to be a need to choose Microactive.

I tried a 50ml sample and it seemed like a moisturizing and mild serum. It didn't seem to particularly suit any skin type and didn't cause any breakouts, so I'd describe it as gentle. Aside from that, there wasn't anything particularly special about it. I personally disliked it a bit due to its slight viscosity, but I gave it to my mom and she said it was soft and moisturizing, and used it well. The Micro Active line has a somewhat gentle feel, so I think it would be good for those with sensitive skin.

The only downside seems to be the price. It's expensive considering the quantity.

Even with sensitive skin, I've been using it without any irritation. The right amount of moisture and oil content is just perfect.

The scent was fine for me, but it may be divisive.
Be cautious of the ingredients!

The spreadability and absorbency are quite good!
The moisture and oil balance are just right for dry skin!!
I really liked it!!! At some point, my standard became Toredan or hyaluronic acid ampoules, but for dry skin, it might be even better than Toredan.
It has a moderate viscosity! I actually liked it being a bit thicker and creamier.


I bought the set with the Secret Essence, and the Secret Essence was so good that the other product felt average in comparison to the price.

It has a nice, creamy texture and good spreadability. The scent is also to my liking.
I thought the repair serum would feel heavy, but it turned out to be just right. I can use it during the day and apply sunscreen on top without it pilling.

Using the powder wash and cream from the same line would be even better.

After using the powder wash, my skin feels so soft and smooth.
Just using the serum alone felt a bit drying, but applying the cream as well works well.

I didn't just buy the serum on its own.
I purchased it as part of a set, or when there was at least a 15% discount, or when there was a gift with purchase.
They also sell it as a special set, so you can check those out and see if that works for you.
I bought it from the official Sulwhasoo website or the official Naver Smart Store.
They sometimes have promotions at Olive Young as well.

Without a discount, it seems a bit pricey.
But I rarely buy it without a discount, so it doesn't really have any downsides.
To be honest, I can't really find any shortcomings.
Even with a discount, it still feels a bit expensive.

I've been using it every morning and evening, and I really like it.
My skin has become softer.

It's like a soothing serum, but I didn't really feel any soothing effects~ I don't think I'll be purchasing this with my own money.

There were no particular positives... The fact that I didn't have any breakouts after using it? Haha.

I'm not sure if I'll end up purchasing it since the price is quite high.

It's chewy yet absorbs well, leaving the skin soft and supple on the outside and moisturized on the inside.

There's nothing bad to report. It was said to have a calming effect, but I'm not entirely sure about that. It was a good product to use in the winter.

The texture has a smooth, non-sticky finish that feels light and airy, making it easy to use without any burden. It's said to penetrate deep into the skin, and it seems to have effectively addressed dryness as well. The fragrance is not too strong, just a subtle, pleasant scent.
