➰ Effectiveness
Although it's more hydrating than the Care Up Serum, I'm not sure about its effectiveness on blemishes. I don't feel like I'm getting satisfactory results for the price, so it might be a better choice to buy a different hydrating serum and use separate products for blemish control!

Combination skin type

✔️ Packaging
I bought this because I heard Isoi was famous for blemish control and brightening products. The design is adorably pink and pretty.

✔️ Fragrance
The scent is the signature rose fragrance that Isoi is known for.

✔️ Texture
It has a slightly crumbly gel-like texture? When applied, it spreads easily as if it's melting into the skin!

✔️ Hydration
While the original Care Up Serum is more popular, I opted for the Care Deep Serum since I have dry skin and needed more hydration. It definitely feels more moisturizing, making it great for skincare during the cooler seasons.

블레미쉬 케어 딥 세럼

There wasn't anything particularly bad. I trust and use Isoi because IU endorses it in the ads.

Haha, it suited me well! It was moisturizing and absorbed nicely, so I used it for 2 years!

After cleansing in the evening and applying toner, I use this as a light essence, followed by a separate application of ampoule.

The shelf life is only 6 months, so you need to use it quickly. While it feels hydrating at first, it becomes matte, making it unsuitable for fall and winter. When used before makeup, it can cause pilling, so I only use it at night.

You can see an immediate brightening effect. I keep it on hand because I think there are noticeable results with consistent use.

High price, small quantity, and minimal brightening effects... Oh, and the transparent tube connected to the pump inside is too short, so when you're almost done with the product, there's still some left that you can't seem to use up.

I bought this when I suddenly became interested in brightening my skin. To be honest, I didn't have high expectations since it's just a cosmetic product, but I'd seen a lot of ads and recommendations from others, so I thought I'd give it a shot. Turns out, it's just a moisturizing rose ampoule. The brightening effect is minimal, and while it does make your complexion look a bit cleaner and more radiant, that's about it. I used up two bottles from a buy-one-get-one-free deal, and I've never used a serum with such little noticeable change before. After some time, I saw it popping up on many 'not recommended' lists, which made me realize I wasn't crazy for feeling underwhelmed. I haven't used it since then, and I have no plans to repurchase it in the future.

Although it's a bit pricey, I'm satisfied because it appears to be effective.

I received this as a gift and it seems to have calmed my blemishes. Very satisfied!

There aren't any real drawbacks or issues with blemishes. It might feel a bit light during winter months.

This is a product I always keep stocked up on. I highly recommend it for all skin types. In my 20s I had oily skin, and now in my 30s I have combination dehydrated skin, but it works well for both. It's comfortable to use regardless of your skin type.

There's a regular version and a deep version, so choose wisely based on your skin's needs.

It's great because it doesn't cause any blemishes! It's suitable for use even in fall and winter.

This is the dry skin version of the famous ISOI Blemish Care Serum! I'm on my second bottle and it's really great. I feel like my blemishes have become clearer, and I love the scent, which keeps me coming back for more.

While it doesn't cause blemishes, it doesn't seem to dramatically reduce existing ones either!

A gentle blemish serum that won't irritate your skin❣️
ISOI's star product, a yearly must-have! It's none other than their famous Rose Water Serum. I bought it first, but my sister ended up stealing it from me - and she loved it even more than I did!

The texture is slightly sticky! While I'm not usually a fan of sticky products, I was pleasantly surprised by how lightly it absorbed into my skin. The fact that I didn't experience any blemishes while using it suggests that it's truly gentle on the skin!

I think I should try purchasing a complete set for blemish care, from toner to cream, to give it a fair shot

Didn't really notice any blemish control effects

While my face felt soft, hydrated, and well-moisturized, the blemishes didn't seem to disappear

My first experience with ISOI products

I've heard a lot about ISOI and seen their products in stores, but I never considered buying them due to the price. However, thanks to the power of TikTok, I decided to give it a try. 

The product definitely provides hydration and moisturization, which I could feel. However, in my opinion, a blemish product should help manage spots and even out the complexion, but I didn't really notice those effects. 

It's possible that this is because I didn't use the toner and cream specifically designed for blemish control. I'm not opposed to the idea of purchasing an ISOI set in the future when I'm mentally prepared, to give it a proper try.

It appears to be effective when applied generously, but the price makes that challenging.

However, if you stop using it regularly, your complexion seems to revert to its original state. It doesn't provide long-lasting hydration.

When used intensively for about two weeks, there's a noticeable brightening effect on the face. It also seems to refine skin texture. The product absorbs immediately upon application.

Unfortunately, this product doesn't seem to agree with my skin. It caused my skin to develop a bumpy texture and become itchy. Despite not wanting to waste it, I tried applying it to specific areas a few more times after the initial reaction subsided. However, without fail, my skin reacted negatively each time I used it. I struggled with this for quite a while.

The product absorbs well and has a refreshing texture, making it ideal for those who like to layer multiple skincare products.
