This complete system combines several types of products in one package. If someone wishes to use all of these different products, then it definitely can be a better price than buying each part individually. But if someone is not sure whether or not he will use all the different parts, he may be better off getting the few individual parts that he definitely needs. Even though he is getting less product, it can be cheaper than paying more for several products that he won't use. But especially if someone wants to use all of these products, this is probably about the best format to buy it in. Effectiveness This can help, except perhaps in extreme cases of bad acne. Side Effects Personally, I have never experienced any negative side effects from this product. However, that can vary from person to person. One should always consult the warnings and potential side effects before use. Immediacy This seems to work quite well, especially considering that it is an off-brand product.
