Studies / Healing after procedures and wounds
Placental exosomes on the skin for healing after aesthetic procedures
Peredo M, Shivananjappa S, Journal of Drugs in Dermatology, 2024
Improvement reported, no control group: Patients improved, but without a comparison group there is no way to tell whether the treatment caused it.
Level 1 of 5: One patient or a handful, described without a comparison. It can raise an idea; it cannot show that a treatment works.

Other studies of healing after procedures and wounds
- No benefit over control
Donor platelet vesicles injected into small skin wounds
Johnson J et al., Journal of Extracellular Vesicles, 2023. 11 healthy volunteers. Made from: donor platelets.
Safe and well tolerated. Wounds healed in about 23 days on average whether they got the vesicles or placebo.
- Better than control
The patient's own serum vesicles for chronic venous leg ulcers
Gibello L et al., Pharmacological Research, 2023. About 5 patients. Made from: patient's own blood serum.
Treated ulcers formed more healthy granulation tissue than sham-treated ulcers: 3 of 5 treated ulcers reached 75–100% granulation, compared with none of the sham-treated ones.
