Ingredient review
Perfluorocaprylyl Bromide
INCI: PERFLUOROCAPRYLYL BROMIDE
A synthetic fluorinated compound that may help deliver oxygen to the skin, but its cosmetic benefits are not well-established and it is rarely used.
In plain English
Perfluorocaprylyl bromide is a man-made ingredient that belongs to a group of chemicals called perfluorocarbons. These chemicals can carry and release oxygen, which is why they are sometimes used in medical settings. In skincare, it is added to creams and serums with the idea that it might help deliver oxygen to the skin, potentially improving radiance or aiding recovery. However, there is very little research on its effectiveness in cosmetics, and it is not a common ingredient in everyday products.

Quick decision guide
Useful, but context matters
Perfluorocaprylyl Bromide is generally a lower-concern ingredient when the full formula suits your skin.
Plain-English read
Treat this as a practical screening step before you compare products that contain this ingredient.
- Step 1Start with the score, then check the irritation and clogging risk before judging Perfluorocaprylyl Bromide.
- Step 2Use the "Best for" and "Use caution if" sections to match the ingredient to your skin, not just to a marketing claim.
- Step 3If a product stings, breaks you out, or worsens irritation, judge the finished formula and stop using it even if the ingredient scores well.
Score terms in plain English
Irritation risk
lowLess likely to sting, burn, or bother most users, though sensitive skin can still react.
Clogging risk
lowLess likely to feel heavy or contribute to clogged pores for most skin types.
Evidence level
emergingThe ingredient may be promising, but claims should be treated more cautiously.
What it is
Perfluorocaprylyl bromide is a synthetic perfluorocarbon, a type of molecule where hydrogen atoms are replaced with fluorine and bromine. It is a clear, colorless liquid that is chemically stable and can dissolve large amounts of oxygen.
How it works
In a cosmetic product, perfluorocaprylyl bromide is thought to act as an oxygen carrier. When applied to the skin, it may release oxygen onto the skin's surface, which could theoretically support skin cell metabolism or create a temporary feeling of freshness. However, this mechanism is not proven in typical skincare use, and the skin already gets oxygen from the bloodstream.
Pros
Unique oxygen-carrying property
The ingredient can hold and release oxygen, which is a novel concept in skincare, though its practical benefit is unproven.
Smooth texture
It can improve the feel of a product, making it silky and lightweight on the skin.
Cons and cautions
Lack of proven efficacy
There is no strong scientific evidence that delivering oxygen to the skin surface via this ingredient provides any real cosmetic benefit.
Rare and potentially unnecessary
It is not a common ingredient, and its inclusion may be more about marketing than actual skin improvement.
Best for
- People interested in experimental or high-tech skincare ingredients
- Those looking for a unique texture in their moisturizer
Use caution if
- Anyone with sensitive or reactive skin (due to lack of safety data)
- Those who prefer well-researched, proven ingredients
Usage tips
Safety summary
Perfluorocaprylyl bromide is considered low risk for skin irritation and comedogenicity based on limited data, but its long-term safety in cosmetics is not well-studied. It is generally safe when used in low concentrations.
Research notes
Research on perfluorocaprylyl bromide in cosmetics is minimal. Most studies focus on its medical use as an oxygen carrier. Cosmetic benefits remain theoretical and unsubstantiated.
Common label clues
- Typical concentration
- Typically 0.1% to 5% in leave-on products
- Regulatory status
- Allowed in cosmetics in the US and EU, but not widely reviewed by safety panels specifically for cosmetic use.
- Common uses
- Moisturizers, Anti-aging creams, Eye creams, Serums
- Environmental note
- Perfluorocarbons are highly stable and can persist in the environment, which is a concern for sustainability.
Good to know
- Perfluorocaprylyl bromide is also used in medical imaging and as a contrast agent, which is very different from cosmetic use.
- This ingredient is not biodegradable and may persist in the environment, raising some ecological concerns.
