Cortexolone 17alpha-propionate 1% cream, a new potent antiandrogen for topical treatment of acne vulgaris. A pilot randomized, double-blind comparative study vs. placebo and tretinoin 0.05% cream. [2011.07]
BACKGROUND: Acne vulgaris is a disorder of the pilosebaceous unit in which the androgens contribute to its onset and persistence. The use of antiandrogens is therefore potentially effective; however, antiandrogens for topical use are not available on the market. Cortexolone 17alpha-propionate (CB-03-01; Cosmo S.p.A, Lainate, Italy) is a new potent topical antiandrogen potentially useful in acne vulgaris. OBJECTIVES: To evaluate the safety and the topical efficacy of CB-03-01 1% cream in acne vulgaris as compared with placebo and with tretinoin 0.05% cream (Retin-A(R) ; Janssen-Cilag)... CONCLUSIONS: This pilot study supports the rationale for the use of topical antiandrogens in the treatment of acne vulgaris. CB-03-01 1% cream seems to fit with the profile of an ideal antiandrogen for topical use. (c) 2011 The Authors. BJD (c) 2011 British Association of Dermatologists 2011.

Retin-A Micro review by 48 year old female patient

Overall rating:  
Effectiveness:   Highly Effective
Side effects:   Mild Side Effects
Treatment Info
Condition / reason:   blackheads,large pores,sun damage
Dosage & duration:   0.1% (dosage frequency: every other night) for the period of 1 year
Other conditions:   fine lines
Other drugs taken:   claritin
Reported Results
Benefits:   I saw measurable difference in reduction of blackheads and pore size. I was also really happy with the evening of pigmentation. I had sun and age spots as well as freckling and saw a huge difference in the lightening of all these problems. My skin had a much better over all tone a seemed to become firmer over time.
Side effects:   The first few weeks of treatment my skin was peeling a little and I had some red splotches but eventually these symptoms went away.
Comments:   I would wash my face in the evening with a mild cleanser and then every other night when my face was completely dry I would apply a small amount of Retin-A to my face with the exception of the immediate eye area. The evenings that I did not use Retin-A I would use a good night moisturizer.


Retin-A Micro review by 29 year old female patient

Overall rating:  
Effectiveness:   Moderately Effective
Side effects:   Moderate Side Effects
Treatment Info
Condition / reason:   Anti-aging, Acne
Dosage & duration:   .04% (dosage frequency: daily) for the period of 6 months
Other conditions:   None
Other drugs taken:   Nuvaring
Reported Results
Benefits:   The treatment benefits included Skin Regeneration, and decreased Acne. My skin felt more smooth and the pigmentation was disapearing. Overall, the goals were accomplished however the redness of the skin took over.
Side effects:   The side effects of the treatment included Redness, Dryness, Skin Irritation. The skin was very dry and difficult to moisturize. The skin looked red and irritated. However, when I switched to a lighter skin cleanser, Cetaphil, this really helped improve the redness and dryness. Prior to the Cetaphil i was using Roc cleansing pads which were too harsh on my skin.
Comments:   My routine included Daily use of Micro Retin A pump. I applied the Retin A Micro pump to my entire face at night after washing my face. I used a moisturizer and sun screen in the morning.


Retin-A Micro review by 25 year old female patient

Overall rating:  
Effectiveness:   Ineffective
Side effects:   Severe Side Effects
Treatment Info
Condition / reason:   Acne
Dosage & duration:   0.1% (dosage frequency: every night before bedtime) for the period of 3 months
Other conditions:   None
Other drugs taken:   None
Reported Results
Benefits:   None at all; my acne went from mild to severe. I woke up everyday with big new, painful whiteheads. Each time a group of pimples went away, several new ones formed immediately. I also have oily skin, and I read that Retin-A rapidly reduces oil; my skin is just as oily as the day I started and my acne is as bad as when I was a teenager.
Side effects:   My skin has been extremely red the entire time I've taken this medication. It is so drying that even my ears and lips are persistently dry. I need to wear chap stick all day, everyday just to keep my lips from peeling. The area where I most use the cream has also been extremely dry and flaky.
Comments:   I applied it every night before bedtime.
