Tretinoin (0.05% cream vs. 5% peel) for photoaging and field cancerization of the forearms: randomized, evaluator-blinded, clinical trial.

Background: Topical tretinoin cream is the gold standard treatment for skin ageing, particularly photoaging. The purpose of tretinoin peel was to obtain similar results, but in a shorter time, however, there have been few controlled trials on its effectiveness.

Objective: To compare efficacy and safety of tretinoin 0.

Tretinoin peel: a critical view.

The tretinoin peel, also known as retinoic acid peel, is a superficial peeling often performed in dermatological clinics in Brazil. The first study on this was published in 2001, by Cuce et al., as a treatment option for melasma.

Forearm skin aging: characterization by instrumental measurements.

Background: The intrinsic ageing and photoaged skin present biomechanical and morphological differences, which are reflected in the appearance of roughness, superficial and deep wrinkles, atrophy, reduced elasticity, hypo- and hyperpigmentation and actinic keratosis.

Objective: To evaluate and compare the characteristics of the flexor (with a predominance of intrinsic ageing) and extensor (chronically exposed to sunlight and other environmental factors, with a predominance of photoageing) skin surfaces of the forearms.

Methods: Interventional, prospective, diagnostic study, including 23 females, aged over 60 years.

Allergic contact dermatitis among construction workers detected in a clinic that did not specialize in occupational dermatitis.

Background: Contact dermatitis is one of the common work-related dermatoses. Among bricklayers, cement can cause both allergic contact dermatitis and primary contact irritative dermatitis. The personal protective equipment (rubber gloves) may favor the development of allergic contact dermatitis.
