serum
Serums as skin care are wonderful. Unlike rich moisturizers, serums are kinder to my extremely temperamental skin. Where most moisturizers make my skin break out in pimples, serum treat my skin with their wonderful active ingredients, without causing break outs.
Serums tend to be more costly than creams or lotions because they usually contain a higher percentage of the active ingredient. In other words, serums are more effective than creams or lotions. These are well worth the money.
