Summary
This study reports a rare case of titanium dioxide (TiO2) particle deposition in the skin, causing blue macules. The discoloration was linked to triamcinolone acetonide injections for alopecia areata.
Area of Science:
- Dermatology
- Materials Science
- Toxicology
Background:
- Cutaneous discoloration from dermal deposits of titanium dioxide (TiO2) is uncommon.
- Alopecia areata management often involves intralesional corticosteroid injections.

5.3K
The papillary and reticular dermis are the two layers of the dermis. They are made of connective tissue with fibers of collagen extending from one to the other, making the border between the two somewhat indistinct. The dermal papillae extending into the epidermis belong to the papillary layer, whereas the dense collagen fiber bundles below belong to the reticular layer.

Underlying the papillary layer is the much thicker reticular layer, composed of dense, irregular connective...

Transdermal drug delivery systems (TDDS) enable the controlled release of drugs across the skin into systemic circulation. They are particularly advantageous for drugs with short half-lives or narrow therapeutic indices, as they maintain consistent plasma concentrations and reduce the risk of subtherapeutic or toxic levels.TDDS are categorized into monolithic, reservoir, and mixed systems. Monolithic systems embed the drug in a polymer matrix, where diffusion governs release. Reservoir systems...
