I see a lot of people (myself included) using one lotion after the other. When one gets finished, you simply walk to the cosmetic shop and purchase one without consultation. I have a feeling that this is detrimental to your skin because these might contain certain components whose effects might cancel each other out. Besides you might be using a lotion that does not meet your skin needs.
For starters, I think that is why we have dermatologists. Visiting them will go a long way in making the skin healthy and smooth. Speaking of which, it is time I got my own personal dermatologist.
