Stem cell use is fairly widespread in the cosmetic industry. However, it is usually in cream form and the cells have less icky origins – they tend to be plant-based. The theory goes that adding stem cells to the dermal layer rejuvenates skin because it is effectively introducing new tissue, thus making one's complexion appear younger. The process is also thought to release chemicals that aid aging cells, again, making them appear younger.
Studies have shown that stem cells can repair damaged tissue – for example, wounds and burns – but it is not so clear how effective they are as a radiance-boosting treatment. Blanchett's post-facial glow could have just as much, or perhaps more, to do with the chemical peel, the electrifying mask, and the peptides.
Anyway, with a two-year waiting list and each session costing $650 a pop, you probably couldn’t get an appointment even if you wanted to.
IFLScience has reached out to stem cell experts to clarify the benefits and risks of stem cell facial treatments.
