Niccy, a reader of CamCheck asks: “Hi, does Cocoa Butter formula really work for stretch marks.”
We searched PubMed for studies about Cocoa Butter and stretch marks.
(“PubMed comprises more than 26 million citations for biomedical literature from MEDLINE, life science journals, and online books. Citations may include links to full-text content from PubMed Central and publisher web sites”)
We found 5.
None support the claims that cocoa butter is effective for stretch marks.
 Striae distensae (SD) are common dermal lesions, with significant physical and psychological impact. Many therapeutic modalities are available but none can completely eradicate SD.
Additionally, tretinoin used therapeutically showed varying results whilst cocoa butter and olive oil did not demonstrate any effect.

 Striae gravidarum (SG), or stretch marks developing during pregnancy, affect up to 90% of women. While not medically dangerous, SG can be disfiguring, causing emotional and psychological distress. However, studies specifically addressing the prevention of SG, especially during pregnancy, are sparse.
Finally, cocoa butter and olive oil are not effective for preventing SG or reducing the severity of lesions. We conclude that reliable methods for preventing SG are scarce.

 No topical agent has been proven to prevent or reduce stretch marks. Randomized controlled trials show that cocoa butter doesn’t prevent stretch marks ; neither does olive oil.

 Topical application of a lotion containing cocoa butter does not appear to reduce the likelihood of developing striae gravidarum.
