Ingredient review
Rapeseed Sterols
INCI: Brassica Campestris Sterols
A gentle, plant-based ingredient that mimics the skin's natural lipids to strengthen the moisture barrier and soothe dryness.
In plain English
Rapeseed sterols are natural compounds extracted from rapeseed (canola) oil that work like the fats your skin naturally produces. They help fill in the gaps between skin cells, making the outer layer stronger and better at holding in water. This keeps your skin feeling soft, smooth, and less prone to irritation from the environment.

Quick decision guide
Easy yes for most routines
Rapeseed Sterols 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 Rapeseed Sterols.
- 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
moderateThere is useful support, but formula details and claim strength still matter.
What it is
Brassica Campestris Sterols are a group of plant-derived sterols (phytosterols) extracted from rapeseed oil. They are waxy, lipid-like molecules that closely resemble cholesterol, a key component of the skin's natural barrier.
How it works
When applied topically, these sterols integrate into the lipid matrix between skin cells. They help repair and reinforce the skin barrier, reducing water loss (transepidermal water loss, or TEWL) and protecting against irritants. This creates a smoother, more resilient skin surface.
Pros
Barrier-friendly
Rapeseed sterols mimic the skin's natural lipids, helping to repair and maintain a healthy moisture barrier without clogging pores.
Very gentle
With low irritation and comedogenic risk, this ingredient is suitable for most skin types, including sensitive and acne-prone skin.
Cons and cautions
Less researched than alternatives
While promising, rapeseed sterols have fewer clinical studies backing their efficacy compared to well-known barrier ingredients like ceramides.
May be less potent alone
For significant barrier repair, it works best when combined with other lipids (e.g., fatty acids, cholesterol) rather than as a standalone ingredient.
Best for
- People with dry or dehydrated skin looking for barrier support
- Those with sensitive or easily irritated skin who want a gentle moisturizing ingredient
Use caution if
- Individuals with a known allergy to rapeseed or canola oil (rare, but possible)
Usage tips
Safety summary
Rapeseed sterols are considered safe for topical use with very low irritation and allergy potential. They are non-comedogenic and well-tolerated even by sensitive skin. No significant safety concerns have been reported in cosmetic concentrations.
Research notes
Research on phytosterols, including rapeseed sterols, shows they can improve skin barrier function and hydration. However, most studies are on broader phytosterol blends or animal models; direct human studies on rapeseed sterols specifically are limited but supportive.
Common label clues
- Typical concentration
- 0.5% to 3%
- Regulatory status
- Approved for use in cosmetics globally, including by the EU CosIng database and the US FDA as a cosmetic ingredient. No known restrictions.
- Common uses
- Moisturizers, Anti-aging creams, Barrier repair products, Eye creams
- Environmental note
- Rapeseed is a widely cultivated crop; choosing products with sustainably sourced rapeseed sterols can reduce environmental impact.
Good to know
- Rapeseed sterols are often listed under the INCI name 'Brassica Campestris Sterols' and are sometimes called canola sterols.
- They are vegan-friendly and a sustainable alternative to animal-derived cholesterol in skincare.
