The potassium alum in Nu-Derm Toner is a potent absorbent and topical disinfectant that can be a skin irritant, and the witch hazel distillate is mostly alcohol, which also can be irritating and drying for skin. Moreover, this product does not return skin to a good pH because the potassium alum has a very high pH, something that is not helpful for skin.
Formulated with witch hazel and alum, a natural astringent, it adjusts the pH level of the skin for optimal penetration of Obagi Nu-Derm Systems treatment applications.
Strengths:Selection of good water-soluble cleansers; some effective skin-lightening and tretinoin products.
Weaknesses: Expensive; some products available only via prescription, which can be inconvenient; disappointing anti-acne products; moisturizers should contain more state-of-the-art ingredients.
Obagi is a skincare line which got its start back in 1988, spearheaded by Beverly Hills-based dermatologist Dr. Zein Obagi, who has since left the brand. Choosing to focus on the skin issues that plague many aging adults (chiefly, skin discolorations from sun damage and other sources and wrinkles), Obagi offers a mixed bag of cosmetic and prescription products sold only through authorized physicians, plastic surgeons, and accredited medical spas. That exclusivity may increase this line's cache with consumers, but let me assure you that most of what's offered isn't all that exceptionaland what's available by prescription can be prescribed in other forms by any dermatologist, so you don't need to seek one that retails Obagi's products. The highlights of this line are actually the prescription products. Several options with 4% hydroquinone are available as well as two products with tretinoin. There is a significant amount of research demonstrating that 4% hydroquinone, especially when combined with tretinoin, has a high success rate for persons dealing with stubborn skin discolorations or the skin condition melasma (Sources: Journal of Cosmetic Dermatology, March 2007, pages 3639; Cutis, January 2005, pages 5762, and March 2006, pages 177184).
The skin-care products Obagi sells to support the prescription-only options are either standard or below-average formulas that are easily replaced by less expensive options from other lines. Beware: This is a line whose proponents are adamant about the products being used as a system, so expect pressure to purchase an entire routine rather than cherry-pick what you really need. Savvy shoppers will find some viable options from Obagi, including a very gentle, fragrance-free sunscreen for someone with sensitive skin.
