Does deep chemical peeling cause telangiectasia?
I'm a pharmacist from the cosmetic industry. I'd like to study about telangiectasia. Some articles say that deep chemical peeling can cause telangiectasia. As the definition of telangiectasia, small widened blood vessels on the skin surface, so how can chemical peeling widen blood vessels on the skin surface? Thank you
The issue is often the Depth of the Chemical Peel. With some Peels there can be a higher likely hood that there is a requirement for revascularization to occur as part of the healing process. Sometimes this can result in the formation of telangiectasia's. This can also be related to a patients skin type, medical problems and medications the patient may be taking.

You are correct that deep chemical peeling or laser resurfacing can often increase the appearance of telangiectasia and the appearance of small blood vessels on the facial skin.
There are two apparent causes for this. First chemical peeling and laser resurfacing both remove superficial epidermis which essentially "uncovers" or makes visible blood vessels that were previously covered and concealed by thickened epidermis.
Second, both deep chemical peeling and laser resurfacing are very inflammatory procedures which cause severe inflammation of the skin. The response of the skin and body to inflammation is the production of new dilated blood vessels presumably to remove debris caused by inflammation and also to send inflammatory cells into the area to restore and repair the skin following injury.
This is commonly seen with chemical peeling and is something I warn patients about. By removing the epidermis and a degree of dermis, the re-revascularization can cause the telangiectasia. The depth also will play a role in the width and extent of the revascularization.
The degree of inflammation cause by the injury can also affect the revascularization. Good luck
