First off, I love the glass bottle and dropper. Not quite sure how much to use, 2-3 drops seems too little. The texture is pretty watery, so be careful when applying. I'm new to centella asiatica, but my skin wasn't irritated at all, though I don't really see a difference in my skin either. I'm not dry at least, so I will continue to use this every night, and we'll see if I want another bottle when I run out.
