Quick question – pimples come to a head?! [benzoyl peroxide] [acne treatment]

I have a quick question. I just started using Neutrogena acne spot treatment 2.5% benzoyl peroxide. I used it for the first two nights ago. I rarely get acne to a head. So I put it on the acne I had and woke up yesterday morning on most of them are white heads! The head looks really as kind of greenish / yellowish. I put it on again last night and woke up this morning with a few of the smaller not have a head more and more feel dehydrated, although still a head. I can feel them, wounding one bit.

My kinda question is whether this means that works? Ive heard people say things sometimes get worse before they get better and / or some medication to put potential breakouts. I do not know exactly when whiteheads are worse than non-white heads, but to me they look worse. I decided to order this product because I had some success with using Proactiv, but it was expensive. I did not want a product with higher levels of benzoyl peroxide, or try. I thought it might also harsh.

I plan to wait it out to see what happens, but does anyone have any answer to this questions.

Thanks!
