Kiehl’s Dermatologist Solutions Breakout Control Acne Treatment Facial Lotion and Kiehl’s Dermatologist Solutions Targeted Spot Control Treatment and the two newest incarnations from Kiehl’s. The products are designed with an impressive array of ingredients together encompassing 10% sulfur, 4% niacinamide (estimated), 1.5% salicylic acid and 1.5% glycolic acid. The base of each product is also impressive, allowing the ingredients to penetrate the skin, but preventing the ingredients from drying out or irritating the skin (like so many other acne treatments do!). I’m a huge fan of these products. Below, I’ll review each separately:
Kiehl’s Dermatologist Solutions Targeted Spot Control Treatment Review
Kiehl’s Dermatologist Solutions Targeted Spot Control Treatment is the first treatment I know of that is clinically proven to reduce the size, height, and redness of blemishes in just one day. The magic ingredients are 10% sulfur, and also an impressive concentration (I estimate 4%) of niacinamide.
Sulfur helps to clean out pores and curb the growth of acne (The DERMAdoctor Skinstruction Manuel). It clears pores because it’s been found to have keratolytic action, which means it dissolves the outer layers of skin, removing dead skin cells and cleaning pores (Journal of the American Academy of Dermatology). It also has antibacterial and antifungal properties with little adverse reaction on skin, making it useful for treating a host of dermatological conditions including rosacea and seborrheic dermatitis (Journal of Drugs in Dermatology). Sulfur also has drying properties, which help the skin to heal. Numerous studies have found sulfur to be effective against fighting skin redness, including a 1997 study in the Journal of Dermatological Treatments.
HOW TO USE
After cleansing skin, cover the entire affected area with a thin layer of product. Use once daily until blemish is gone, and increase to two or three times daily if needed.

Kiehl’s Dermatologist Solutions™ Breakout Control Acne Treatment Facial Lotion
Kiehl’s Dermatologist Solutions Breakout Control Acne Treatment Facial Lotion is a new lightweight lotion that contains 1.5% salicylic acid and, again, niacinamide.
Salicyclic acid is a beta-hydroxy acid that is used to cleanse and exfoliate the skin. According to Dr. Heather Brannon, M.D., a family-practice physician with a specialty in Dermatology, salicyclic acid is also reported to improve signs of aging including wrinkling, roughness, and mottled pigmentation of photodamaged skin with at least 6 months of daily application.
According to DermNetNZ, salicylic acid works by softening keratin, a protein that forms part of the skin structure. This helps to loosen dry scaly skin, increasing cell turnover and effectively renewing the skin. It is often used in acne treatments to cleanse and to prevent clogging of the pores.
When salicylic acid is used in combination with other treatments, it is often to allow the other formulation’s ingredients to penetrate the skin more effectively.
As for niacinamide, well, it’s an amazing ingredient. According toBissett et. al., niacinamide does it all: reduces fine lines and wrinkles, hyperpigmented spots, red blotchiness, and skin sallowness (yellowing), and increases elasticity. Further, according to a 2005 study by Draelos et. al., niacinamide may help alleviate some of the symptoms of rosacea by increasing hydration and barrier function of the stratum corneum (uppermost layer of the skin), and may have some anti-tumor characteristics as well. And finally, in a 1995 study by Takozaki et. al., it was reported that a 4% topical niacinamide treatment applied twice daily may help to treat acne by reducing inflammation with similar efficacy to 1% clindamycin gel. What’s not to love?

More and more treatments are promising to deliver results faster and better. In the case of acne, Kiehl’s Dermatologist Solutions Breakout Control Acne Treatment Facial Lotion and Kiehl’s Dermatologist Solutions Targeted Spot Control Treatment are the first to reduce the appearance of acne in just one day. With a formulation that includes salicylic acid, niacinamide, sulfur, and glycolic acid, as well as a non-drying formulation, I say that the lotion is a great everyday addition to a skincare routine if you have oily or acne-prone skin, and the spot treatment will be living in my medicine cabinet full-time. Can I get a yay?
