This is the worst product I have ever used. Please avoid this if you have sensitive skin!

This is an incredibly gentle serum for acne. It has a great reputation for being mild even on sensitive skin, so I applied for a sample to try. But oh my gosh, it was fine when I tested it on the back of my hand. I applied just a tiny bit—a tiny amount at a time—after cleansing and applying my basic skincare in the evening. I woke up in the morning expecting smooth, flawless skin like a peeled egg, but my skin was completely broken out, and it took about two weeks to get back to normal.

If you are sensitive, be sure to test on the back of your hand or the inside of your arm.

You should give it a try... After thinking it over carefully, I think the reason isn't that the product is bad, but rather because of my bad skin...
