If you are using retinol for the first time, please use it with caution!

I impulsively bought it because I heard it improves the skin, but I messed up the amount and my face broke out in a total disaster. They told me to mix only a tiny amount—like a grain of rice—at first, and I really should have listened to that. My skin has finally calmed down, but I hope anyone new to retinol makes sure to read the precautions before using it. Otherwise, you will suffer like I did.
