Skin.
Level 5 - mechanism / opinion, no new human data
Narrative review without systematic search or meta-analytic data
What was done
Narrative review describing mechanisms and clinical implications of cutaneous vulnerability to topical medications, environmental toxins, teratogens, and ultraviolet (UV) radiation across developmental stages from the embryonic period through adolescence.
What was found
The abstract reports no quantitative data or statistical estimates. It identifies qualitative risks and mechanisms: teratogenic associations with methimazole (aplasia cutis congenita); increased percutaneous absorption and systemic drug toxicity (e.g., from alcohol, hexachlorophene, iodine compounds, EMLA, and lindane) in premature infants due to epidermal barrier immaturity and immature metabolism; heightened lifetime risk of malignant melanoma associated with childhood UV exposure, severe sunburns, and melanocyte susceptibility; and differences in toxicant exposure (e.g., insecticides, polychlorinated biphenyls) driven by pediatric behavioral, anatomical, and physiological factors.
Why it matters
The review summarizes why pediatric skin cannot be treated simply as miniature adult skin, emphasizing cautious topical dosing in neonates and early-life photoprotection.
Limits
The abstract provides no empirical sample sizes, quantitative effect estimates, or systematic review methodology, representing an unsystematic narrative overview.
