C-Clarifying Serum is a prescription-only product that lists 4% hydroquinone as the active ingredient. It is formulated in a simple gel base that contains L-ascorbic acid, a form of vitamin C that has antioxidant benefits. The pH of this serum allows the vitamin C to be efficacious, but also potentially irritating. This is a definite option for lightening skin discolorations related to sun damage or hormones, but would have been even better if Obagi had included a roster of anti-irritants.

The first an only patented combination of prescription strength 4% Hydroquinone and 10% L-Ascorbic Acid at a pH of 2.5-3.0, this serum penetrates deep into the skin’s dermal layers, where it enhances collagen production and reduces melanosome activity and tyrosinase activation, making skin Photolumines.

Active: Hydroquinone (4%), Other: Propylene Glycol, Propylene Carbonate, L-Ascorbic Acid (Vitamin C), Purified Water, Sodium Lauryl Sulfate

Dermatologist Zein E. Obagi is behind this line, which claims to be your skin's key to transformation. 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 exceptional—and 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 36–39; Cutis, January 2005, pages 57–62, and March 2006, pages 177–184).

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.

One more point: Obagi is also "known" for his Blue Peel. This is a standard trichloroacetic acid (TCA) peel that has been performed by dermatologists and plastic surgeons for years; Obagi simply instructs the practitioner to mix the TCA with a blue-tinted base. TCA is used for peeling the face, neck, hands, and other exposed areas of the body. It causes fewer pigmentation problems than other doctor-only peels such as phenol, and is considered excellent for "spot" peeling specific areas. It also can be used for medium or light peeling, depending on the concentration and method of application. AHA and BHA peels are considered light peels, and are often done in a series of six. TCA peels are best for fine lines and can be somewhat more effective on deeper wrinkling, but they are performed only once every couple of years. Many of the dermatologists we spoke to believe that a TCA peel is a viable option for many skin types, despite consumers' fascination with AHA peels.
