Because skincare became a global issue, knowledge and understanding of the different active ingredients in many skincare products also became an important requirement, specially for those who are regularly using these products. Skincare experts, like dermatologists, always stress out the need to pick out products that are clinically-tested effective and safe. Patrons of these products have to know what is inside every cream, oitment, lotion, astringent, etc. they are buying. The number of active ingredients in most skincare products may shock consumers. As many of these ingredients are unfamiliar and worse not easily read by buyers, they only rely on other people’s experience and feedback about the product without even considering the fact that a product may be effective for one, but harmful for another.
