NEWS HIGHLIGHTS
Published Studies Related to Retin-A (Tretinoin Topical)
Tolerability of high-dose topical tretinoin: the Veterans Affairs Topical Tretinoin Chemoprevention Trial. [2009.10] BACKGROUND: Topical tretinoin is a medication commonly used for acne that has potential application in the long-term treatment of photodamaged skin. However, there are few published data regarding the tolerability of high-dose tretinoin with long-term use. OBJECTIVES: To assess the long-term tolerability of tretinoin 0.1% cream... CONCLUSIONS: Overall, the tolerability level of topical tretinoin was high in this study population, with almost 40% of the tretinoin group reporting no side-effects, and the majority (67%) tolerating at least once-daily dosing at 6-month follow-up. High-dose topical tretinoin is feasible for long-term use in this population.
Benefits of using a hydroquinone/tretinoin skin care system in patients undergoing intense pulsed light therapy for photorejuvenation: a placebo-controlled study. [2009.09] A hydroquinone/tretinoin (HQ/tret) skin care system designed for use with non-surgical facial rejuvenation procedures has recently become available. In this observer-masked study, 36 patients with moderate-to-severe wrinkling of the skin around the eyes and lips were randomly assigned to use either the 4% hydroquinone/0.05% tretinoin skin care system or placebo products, each day for 90 days...
Quality of life in the actinic neoplasia syndrome: The VA Topical Tretinoin Chemoprevention (VATTC) Trial. [2009.08] BACKGROUND: Keratinocyte carcinomas (KCs) are the most common malignancies of the skin. As lesions have a low mortality rate, understanding quality-of-life (QoL) factors is necessary in their management. OBJECTIVE: To assess QoL and associated patient characteristics in those with a history of keratinocyte carcinomas... CONCLUSIONS: A history of ever use of 5-FU and present AKs was strongly associated with worse QoL. We find it more useful to consider these patients as having the chronic condition "actinic neoplasia syndrome," whose burden may be best measured by factors other than their history of KCs.
Comparative efficacy and safety results of two topical combination acne regimens. [2009.07] Combination therapy has become the standard for the management of acne, particularly for moderate-to-severe cases... Both treatment regimens were well-tolerated.
Reappraising the phototoxicity of tretinoin: a report of four controlled clinical trials. [2009.06] BACKGROUND: Retinoids are photoreactive molecules found in skin and retinal tissue. The use of retinoids in pharmacologic doses, applied topically, raises the potential of phototoxicities. Recent review articles and current US drug labeling indicate that tretinoin is a phototoxin. In developing a new formulation of topical all-trans-retinoic acid (tretinoin), formal testing of dermal photoreactions was therefore undertaken... CONCLUSION: The findings in these studies are consistent with previous studies of tretinoin in various formulations, and support the conclusion that tretinoin appears to be neither phototoxic nor photoallergenic in vivo.

| | Retin-A review by 24 year old female patient | | | Rating |
| Overall rating: | |           |
| Effectiveness: | | Highly Effective |
| Side effects: | | Mild Side Effects | | | Treatment Info |
| Condition / reason: | | minor acne |
| Dosage & duration: | | .01 (dosage frequency: every day) for the period of a year |
| Other conditions: | | dry skin |
| Other drugs taken: | | none | | | Reported Results |
| Benefits: | | My skin stopped breaking out as often and became much softer and smoother. The color really improved as well - much less blotchy and more "dewy." |
| Side effects: | | Very dry skin. A lot of peeling. |
| Comments: | | After washing my face with a gentle cleanser, I would wait 20 minutes and then put on the cream. I would then wait another 20 minutes and put some lotion on because the tretnoin was just too drying. |

| | Retin-A review by 28 year old male patient | | | Rating |
| Overall rating: | |           |
| Effectiveness: | | Moderately Effective |
| Side effects: | | Moderate Side Effects | | | Treatment Info |
| Condition / reason: | | Acne |
| Dosage & duration: | | 0.01% (dosage frequency: once a day) for the period of 2 years |
| Other conditions: | | none |
| Other drugs taken: | | none | | | Reported Results |
| Benefits: | | Reduced acne. I had mild/moderate acne, and Retin-A did decrease the amount of ance I had. I liked Retin-A also because it reduces wrinkles. I am only 28, so I don't have many wrinkles, but used it as prevention. |
| Side effects: | | My skin would become too dry. It seemed that even after months of usage, my ance would not completely disappear. If I used more Retin-A, my acne would get better for a week or two until my skin became too dry and then I would have worse acne |
| Comments: | | I would apply Retin-A to my face once a day at night |
