Spreadability When using the serum, spreadability is also an important consideration, but it was absorbed quickly without any slipperiness or stickiness. Even when layering and applying, there was zero stickiness and zero heaviness, and it felt moist and refreshing. After application, the skin feels taut and firm. Moisture While the main focus of the product is blemish improvement, the moisture level was surprisingly good. As a dry-skinned person, it felt just right for my dry skin. Complexion This is truly an amazing product. I used to think my complexion looked dull every time I looked in the mirror, but after using it, I could feel my complexion becoming brighter, and those around me also commented that my skin and complexion looked better. Pigmentation My skin has severe pigmentation issues, but I've seen significant effects. Blemish marks are improving faster, and the uneven pigmentation is becoming more uniform. Skin Texture My skin used to be rough, uneven, and dull, but the texture has become smooth. There's a subtle inner glow as well. Comparing the before and after, the skin texture has improved a lot. Makeup Application Using this, my makeup applies well. With the improved skin texture, makeup naturally adheres better. The absorption is quick, so it doesn't cause the makeup to slip, and the moisture lasts without drying out over time. The adhesion also improves. It's truly an all-in-one serum - my skin makeup adheres perfectly. That's why I always use it before makeup. Sun Protection We all know how damaging UV rays can be to the skin. The Isoi blemish serum soothes and cares for sun-damaged skin, hindering the formation and movement of melanin pigmentation, helping with tone improvement and preventing blemishes from surfacing. It's a smart serum that not only improves but also prevents, plus it has antioxidant effects, so there's no reason not to buy it. Ingredients As someone with sensitive, acne-prone skin, I'm always worried about trying new products, but this has completed sensitive skin irritation testing and is suitable for acne-prone skin. It's also Excellent-rated by the German Dermatest and has vegan certification, so I can use it with confidence.Looking at the full ingredient list, it's easy to see why Isoi is so confident about their ingredients. The effects are stronger, but the irritation is 0.00 - it's just amazing. I haven't experienced any breakouts while using it. Fragrance While I generally prefer fragrance-free, the subtle rose scent is pleasant and not polarizing. Continued use seems to yield even better results, so I plan to keep using it for ongoing care. I'm so glad I found such a great product after a long search. I used to really struggle with blemish marks, but I'm so fortunate to have discovered Isoi. Thanks to the blemish serum, my skin has improved a lot, boosting my confidence. Better skin really does make a difference in one's appearance. I've tried many blemish-targeting serums, but this is the most satisfactory and effective one. Now I understand why it's so popular and well-reviewed - it truly deserves its top ranking. The range of benefits from just one bottle makes it a convenient all-in-one solution, which increases my satisfaction. Without exaggeration, this product is genuinely great, so I strongly recommend everyone to try it.

There were no disappointments about the product, but I wish I had used it sooner.. This is my only regret.

The rose scent is pleasant. The usage experience is very refreshing with this ampoule. While the moisturizing power needs to be supplemented with other ampoules or creams, I was satisfied as I really enjoy the lightweight feel.

Rather than whitening, I used it hoping to improve acne and pigmentation. However, it did not particularly help improve acne scars and pigmentation.

This is a good formulation to use in the summer.
