Globally, the mature skin category amounts to 25 percent of the skin care market and almost 40 percent of the anti-aging market. People are living longer lives than ever before due to better life expectancies, decreased mortality rates, and declining fertility rates.

As the skin changes with age, it becomes thin, loose, and loses fat. Mature clients often find that their veins and bones are more apparent and that injuries to their skin take longer to heal.

Clients always want to know why skin care products are no longer effective and skin care professionals want to understand skin tolerance and resistance when it comes to various skin care solutions.

While most teenagers experience some form of acne, many adults suffer from the condition well beyond their 20s and sometimes even into their 50s. The longer a client has acne, the worse their skin tends to get, often never completely repairing.
