Can I use this product all over my face, or is it really just for spots?

This solution is formulated and described as being suited for targeted use rather than broad application. There are two key reasons for this. First, the formula is very short and contains alcohol, which can be drying. Applying it to your entire face, especially if you have normal or dry skin, may lead to unnecessary dryness or irritation. Second, as a keratolytic, salicylic acid works to loosen bonds between dead surface cells. For most people, this action is only needed on specific areas that tend to feel rough, become congested, or develop flaking – not on the entire facial surface. Using it only where needed maximizes the benefit for those zones while minimizing potential side effects for the rest of your skin.
