Please read!! I read the other review before seeing dr liang and I should of listened. I went anyways because my problem couldn't wait for the other doctors that were booked a month out. But seriously do NOT waste ur time and money on this terrible doctor. I shouldn't even be calling a doctor nor should he even be one! He didn't even talk . He typed on his laptop for 15 minutes! After looking at my face and scalp he says yep you have pimples and told me the medicine ill receive , but when I tried asking questions he didnt give me answers . After trying it one day I peeled broke out and was in alot of pain . Called back and they said "well that's why we gave samples to try." Seriously your a dermatologist. You should know what RIGHT medication to give. After looking at my scalp he simply said it looks better. This was the FIRST time going to see him so I simply said back how can you think it looks better when you haven't seen it before? He smiles. Says nothing. I never in my life right a review or a bad one for that matter. But everyone needs to know and be aware of this so call "Dr. Liang" that has no idea what he's doing. I always ignore reviews because everyone has their opinion. But honestly he's that bad. STAY AWAY!
