Cocoa butter for skin: stretch marks and clogged pores
Cocoa butter is the classic stretch-mark cream ingredient. It has been tested properly, twice, in pregnant women, and the results are not what the label tradition suggests.

Stretch marks in pregnancy: two trials
A double-blind, placebo-controlled trial in Lebanon enrolled 210 first-time mothers-to-be in the first trimester and asked them to apply a cocoa butter lotion or a placebo lotion daily until delivery. Among the 175 who finished, stretch marks developed in 45.1% of the cocoa butter group and 48.8% of the placebo group, with no difference in severity.1
A double-blind trial of 300 pregnant women compared cocoa butter cream with placebo cream from 16 weeks to delivery. Stretch marks developed in 44% with cocoa butter against 55% with placebo, a difference the authors found not significant. They conclude cocoa butter cream does not prevent stretch marks, and found they were more common in younger women and in women with larger babies.2
Two independent trials point the same way: the cream did not significantly prevent stretch marks.
Clogged pores
A 2022 study put patches containing cocoa butter on the upper backs of six volunteers and counted microcomedones, the earliest stage of a blocked pore, with a skin microscope. Microcomedones per follicle were significantly higher than on untreated skin after two weeks, and they were larger at two and four weeks.3
Six people on patches is a method study, not a verdict on how a cream behaves on your face. It is a reason for acne-prone skin to be cautious with a pure butter.
Using cocoa butter with other products
The stretch-mark trials tested lotions and creams containing cocoa butter, not the butter layered with other products.1,2 We did not find a source on layering.
Cocoa butter in pregnancy and breastfeeding
We found no pregnancy- or lactation-specific evidence for this ingredient.
Snifff found no pregnancy-specific evidence. That sits oddly with the two trials above, which tested cocoa butter lotions in pregnant women across several months.1,2 Their abstracts report stretch marks, not safety outcomes for mother or baby, so they do not settle the question.
Evidence on cosmetic products in pregnancy is limited overall, so ask your doctor or midwife about the specific product you use.4
What you will see on the label
The names to look for are Theobroma Cacao (Cocoa) Seed Butter and Cocoa Butter. In Snifff, it reads as Low risk. For the rest of the formula, see what the score means and how to read the list.

A FEW MORE ANSWERS
Common questions about cocoa butter
Does cocoa butter prevent stretch marks?
Two randomised trials found it did not significantly reduce stretch marks in pregnancy: 45.1% against 48.8% in one, and 44% against 55% in the other.1,2
Does cocoa butter clog pores?
In a six-person patch test, cocoa butter produced significantly more early blocked pores than untreated skin.3 It is a small study.
Is cocoa butter good for dry skin?
We did not find a controlled trial of cocoa butter alone for dry skin, so we cannot say.
