Ocular effects of cosmetic products and procedures.

Cosmetic products and procedures can produce adverse effects on the ocular surface, ranging from mild discomfort to vision-threatening conditions. Complications of skin and eye products can be related to allergy or toxicity, often attributable to perfumes. Complications of blepharoplasty may be associated with overcorrection, scarring, or uneven contour of the lid margins, conditions that can cause significant ocular surface disease until they are corrected.
