Many skin care companies base their entire line around one or two active ingredients targeting a specific SKIN CONCERN they are trying to correct. For example some "skin concerns" may include pigmentation, rosacea, acne, or fine lines and wrinkles.
This is a great idea if you are treating only ONE TYPE of skin! Everyone's skin type is different and so are their skin issues and needs.
For a line to be EFFECTIVE, it must have SEVERAL active ingredients to provide ALL of the following -- deeply cleanse pores, moisturizing and hydrating ingredients to maintain and increase moisture, antioxidants to protect from free radical damage, peptides to build new collagen, vitamins and minerals to feed and nourish, exfoliating and rejuvenating ingredients to increase cellular turnover and improve texture and skin tone, as well as an array of specialty ingredients to target other specific needs or issues. - Sheila Malmanis / Founder & Owner, DermaMD Skin Care
