because they don't apply them enough or apply them correctly. In order for an acne cream product to work, one must follow the directions on the packaging or from the dermatologist.
It's unfortunate that the acne scar cream won't work for everyone even if everyone followed the directions perfectly. Acne scars can cause a variety of issues in someone's life, including confidence issues, self-esteem issues, and their perceived attractiveness to others. That's why it's important to make a good effort to use creams correctly to have the best chance of curing scars from acne. The best way to prevent bad scarring is to avoid puncturing acne pimples in the first place, but that's not always possible. The pimples sometimes pop without any outside interference.
The most common belief surrounding acne scars is that only time can heal them properly. Acne scar cream is simply not reliable enough to be recommended for a universal treatment method. While it may not be preferable to keep scars longer than necessary, it's likely that scar creams won't help someone get rid of their unwanted scars. It's better to let time work its magic than to waste money on products that won't do any good, especially considering the current economic climate. The theories behind scar creams make sense, but they just don't seem to work when put into practice.
The bottom line is that some people may find scar creams to be effective, but most people likely will not. Depending on the severity of the scars, a dermatologist may have better options, although those may be expensive. If someone has health insurance that covers dermatologist visits and procedures, then they should explore their options carefully. Wasting time and money on topical creams is probably not the way to go. Maybe in the future the creams will have better formulas that actually work, but for now they are simply insufficient means of covering up acne scars.
