Tretinoin Effects on Skin Thickness

Introduction to Tretinoin Effects

• The British Journal of Dermatology notes that common side effects of tretinoin treatment include dry skin, peeling, scaling, flaking, burning sensation, and erythema, which can make skin feel more sensitive and fragile 1, 2
• The British Journal of Dermatology also reports that this "retinoid dermatitis" can make skin feel more sensitive and fragile, particularly during the first 3-9 weeks 3, 4

Patient Management and Counseling

• The American Academy of Dermatology, as reported by Praxis Medical Insights, recommends reassuring patients that the temporary sensitivity and peeling does not represent skin thinning but rather represents active cellular turnover and remodeling 1, 4
• The British Journal of Dermatology advises that for patients with severe erythroderma and pre-existing skin fragility, retinoids may increase fragility and should be used cautiously 5
• Praxis Medical Insights suggests starting with lower concentrations (0.025% or 0.05%) to minimize irritation while achieving similar efficacy to higher concentrations 4
• The British Journal of Dermatology notes that systemic retinoids can cause mucocutaneous side effects including increased sensitivity and fragility, not histological thinning 3
