브라이트닝 세럼

It works perfectly when you apply aloe vera, let it dry, then gently pat on this serum, and finish with a hydrating moisturizer!

While there aren't any specific drawbacks, I recommend skipping it on days when you have super sensitive skin.

I've been using this product for 7 years, and with consistent use, it's been great for reducing blemishes and brightening my complexion! My skin wasn't particularly bright before, but after regular use, I've received so many compliments on how much lighter my skin has become! It's a lightweight serum that doesn't feel heavy on the face and isn't sticky at all.

For those with super sensitive skin, this product might cause some issues. The brightening effect, while noticeable, doesn't seem to last long. If you're looking for a product that works hard for your complexion without causing irritation, you might want to explore other options that offer better bang for your buck and come in more generous quantities.

Sensitive skin reaction, poor value for money, redness, not cost-effective, small amount

Considering the price, I don't think the results were that impressive. You might be better off trying other products. While it absorbs well, there was some slight irritation. It did seem to brighten my skin, but I suspect that effect is only temporary.

It doesn't dramatically brighten your skin, but you might notice a subtle improvement in your complexion - just enough for you to tell the difference. It's on the pricier side, so I'd recommend waiting for a sale to purchase it.

The subtle rose scent is delightful, and the lightweight texture makes it perfect for applying before makeup in the morning without feeling heavy. What I love most is that with consistent use, my complexion has become clearer and my blemishes seem slightly faded, which I'm really happy about. Just be careful when using the pump dispenser as it can sometimes splash a bit. Overall, it's a great product for soothing the skin and addressing blemishes!

I use this along with my beauty device, and I feel it enhances the effectiveness.

Personally, I'm not a fan of scented products, and this one had a subtle rainy season fragrance.
However, I think most people probably wouldn't mind it.

I really liked how it absorbs well and applies lightly without any sticky feeling.

When using new skincare products, it's always best to patch test first, especially if you have sensitive skin. Consider introducing new products gradually into your routine to minimize potential reactions.

Unfortunately, it was too harsh for my skin and caused discomfort when I applied foundation.

I'm not sure if it was because I used it after a face mask from another brand for 20-30 minutes.

Usually, most products suit my skin, but I felt irritation with this one.

Brightening Serum for Clear Complexion

ISOI / Blemish Rose Serum

After two weeks of use, this product claims to improve deep-set blemishes by 106% and reduce dark spots by 118%.

The plant-based Rose PDRN helps decrease skin inflammation and aids in slowing down the aging process.

The rose fragrance is delightful, and it absorbs quickly, leaving your skin feeling fresh and smooth.

It's perfect for use during the humid rainy season when you don't want to layer on too many products.

It's really expensive, unfortunately.
I can only afford it during sales.
The product runs out too quickly.

Lovely fragrance.
It absorbs into the skin incredibly fast. It makes me feel pampered, like I'm using a luxurious product. There's this sense of "Ah, I'm treating myself to something special."

Use this when you want to feel like a pretty girl... because the effects are rather subtle.

Just an average product, I guess? It didn't seem to have much effect on wrinkles or pores, unfortunately.

The lovely rose scent and moisturizing effect seem great for calming the skin!

The translation maintains the original sentiment while adapting it to sound more natural in English. The informal tone and expressions of emotion have been preserved. Cultural references have been adjusted, and subjects have been added where necessary for clarity.

The amount is too small and it's really expensive. It's seriously pricey. As a student without much money, it's just too costly for me... So disappointing!

I recently purchased this and while I'm not entirely sure, I think it's quite good! There's also a subtle fragrance to it.

The amount is too small, unfortunately. I remember having to buy several at once to have enough product to use.

It's non-sticky and gentle, making it a perfect match for my skin. I don't have to worry about blemishes, and it leaves my face feeling refreshingly clean.

Oh my... Please be really careful with functional products. I didn't realize this wasn't suitable for my skin and used it for a few more days, resulting in clogged pores on my forehead. Now I have to regularly extract sebum to clear them. I'm still regretting using this product. Please, please be cautious when using functional skincare items.

A well-known functional product! If you're interested, I recommend giving it a try.
