Skin Sensitivity: As someone with extremely sensitive, acne-prone skin, I found this product to be surprisingly gentle and non-irritating. While it hasn't dramatically transformed my blemishes, I've noticed gradual improvements. Texture: The formula has a slightly rich consistency. Absorption: It absorbs well into the skin.
ConsDue to its rich texture, I wouldn't particularly recommend this for those with oily skin. If you have even the slightest scratch or wound on your face, it can cause a tingling sensation.

They haven't really come back since.
ConsI'm not sure if it's effective on skin marks. Also, it occasionally causes a tingling sensation, so caution might be needed when using it.

There's a noticeable difference in the amount of sebum that comes out when I use cleansing oil after wearing makeup on days I use this product versus days I don't. I skipped using it for a couple of days and was shocked by how much sebum came out when I cleansed. Since then, I've been using it religiously, and the excess sebum has stopped. This little wonder works hard!
ConsThe container is quite large compared to the actual amount of product inside. Someone might think it contains 40ml at first glance!

I plan to order another bottle once I finish my second one.
ConsThe liquid has a bit of stickiness, so your skin doesn't feel completely matte after application. However, it has effectively tackled my blemishes.

However, when combined with a Vitamin C serum and applied in order, my face became significantly brighter the next day. With consistent use, it does improve acne scars. The blemish improvement effect is particularly remarkable on body skin. I recommend applying it to areas where only scars remain after healing, before using body emulsion. (For those with super sensitive skin, 'I absolutely do not recommend this method.' I've seen people's skin react badly. Even for those without sensitive skin, please use this method only 2-3 times a week. It's said to be quite stimulating for the skin.) # No pilling # Not excessively rich
ConsIt doesn't help at all with hydration or deep moisture. It actually feels a bit drying...? However, it's fine if you apply hydrating products (serums, creams, etc.) well.
TipIf you consistently apply this before body emulsion on areas where only scars remain after blemishes or acne have healed on your body, your skin will become softer and the scars will gradually fade!

I have been using a niacinamide product for several bottles now. I have been using niacinamide for a long time because it is good for skin brightening, skin barrier improvement, and blemishes. Among niacinamide products, this one has an appropriate percentage. In my case, after using it for about 3 weeks, I felt that my skin brightening and skin inflammation were gradually improving.
ConsUpon first use, a slight redness appeared, but from the next day on, there were no further issues. There were no particular disappointments.
TipAfter cleansing, I used the CosRX Pimple Pad and found it to be even better.

My sebum production has definitely decreased, and the number of acne has gradually reduced. Now that I've finished the bottle, I only get the occasional small acne or a couple of large ones before my period. This is the first time I've seen such a dramatic effect from a serum, so I'm planning to repurchase it after my exams. The best part is the texture - it applies lightly and absorbs really well. I use it both morning and night, and it doesn't make my skin oily in the morning. Here's a great tip - if you use a cleansing oil to really clean out your pores first, and then immediately apply the serum, it might sting a bit and turn red, but over time the effects are amazing and the redness goes away within a couple of days. And if you use this serum together with the Innisfree Retinol Cica Ampoule towards the end, the effects are doubled! I've been getting compliments on my skin from my friends lately. Please, please, please try this product!!
ConsIt stings a bit, but it's still a good kind of pain. The real disappointment is that the amount is too little ๐ข Please increase it!!!!! And another thing that bothers me is that I can't see how much serum I've used, so this is also one of the drawbacks.
