Why did I use it for acne marks and uneven-looking skin tone?

After my acne subsided, I was concerned that red marks and dark spots left around my cheeks and jaw made my skin tone look uneven. Rather than expecting a quick change, I added it to my daily routine to care for my skin tone and the appearance of dark spots.

Another reason I chose it was that it is a functional brightening serum containing liposome glutathione and niacinamide.

Is the texture sticky?

When I dispensed an appropriate amount and spread it with a rolling motion, it applied smoothly without feeling stiff or pilling. After it absorbed, it felt more hydrating than as though the serum was sitting on my skin, and I found it less sticky, with less hair clinging to my face.

Can I use it before morning makeup?

I used it in my morning skincare routine as well as at night. In the morning, I applied only a thin layer as needed and let it absorb fully before using moisturizer and sunscreen, and the following steps did not feel especially prone to pilling. At night, I adjusted the amount and applied it a little more generously.


How did my skin look right after applying it?

After it absorbed, my skin texture felt hydrated and looked smoother, with a subtle glow. It looked more like added moisture than an oily shine, and I could see a hydrated glow on my cheeks and cheekbones when they caught the light.

What should sensitive skin keep in mind?

The product information stated that its primary irritation test for sensitive skin recorded an irritation response of 0.00 and no adverse reactions such as erythema, swelling, or itching. Skin reactions vary by person, though, so if your skin is sensitive, it would be best to test a small amount first. I did not experience stinging or discomfort while using it morning and night.

How did I layer it?

After cleansing, I refined my skin texture and applied one thin layer over my whole face. Once it had absorbed fully, I applied a small additional amount around my cheeks and jaw, where red marks or dark spots were more noticeable. Rather than applying a large amount at once, applying a thin layer first and adding more where needed worked well for me.

I do not think acne marks disappear overnight with a single cosmetic product. Still, its light, low-tack feel made this a serum that was easy to keep in my morning and evening routine.
