What is a serum, corrective, or treatment-oriented product? In your skin care routine this is one of the most important steps. Just like cleansers, moisturizers and toners have their place in the routine; correctives play a super important role as well. Your correctives actually have performing ingredients that travel deeper into the layers of skin and truly “correct” an issue; such as acne, pigmentation, and collagen stimulation. Performing ingredients in a formulation are the ingredients that essentially do the job. Some noteworthy performing ingredients that I deem necessary in good skin care are: peptides, resveratrol, alpha hydroxy acids, hyaluronic acid, Vitamins A, B, C, and E. When building a skin care routine or receiving professional treatments incorporating a combination of these ingredients will deliver better overall results!
