Ingredient review
Trihydroxypalmitamidohydroxypropyl Myristyl Ether
INCI: Trihydroxypalmitamidohydroxypropyl Myristyl Ether
A synthetic ceramide mimic that strengthens the skin barrier and locks in moisture without clogging pores.
In plain English
This ingredient is a lab-made version of the fatty molecules naturally found in the outer layer of your skin. Think of it as a repair patch for your skin barrier — it fills in gaps between skin cells to keep moisture in and irritants out. It's often used in moisturizers and anti-aging products to help dry or sensitive skin feel smoother and more resilient.

Quick decision guide
Useful, but context matters
Trihydroxypalmitamidohydroxypropyl Myristyl Ether 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 Trihydroxypalmitamidohydroxypropyl Myristyl Ether.
- 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
A synthetic lipid molecule designed to mimic the structure and function of natural ceramides, which are key components of the skin's outermost barrier.
How it works
It integrates into the lipid matrix between skin cells, reinforcing the barrier and reducing water loss (transepidermal water loss, or TEWL). This helps keep skin hydrated, calm, and protected from environmental stressors.
Pros
Barrier repair
Helps restore the skin's natural protective layer, reducing water loss and improving hydration over time.
Gentle for sensitive skin
Low irritation and comedogenic risk make it suitable for reactive or acne-prone skin types.
Cons and cautions
Synthetic origin
Some consumers prefer naturally derived ceramides; this lab-made version may not align with 'clean beauty' preferences.
Limited research
While structurally similar to natural ceramides, there are fewer peer-reviewed studies specifically on this ingredient's long-term effects.
Best for
- People with dry or dehydrated skin
- Those with a compromised skin barrier (e.g., from over-exfoliation or harsh weather)
Use caution if
- Individuals with known sensitivity to synthetic ceramide analogs (rare)
Usage tips
Safety summary
Considered safe for topical use at typical concentrations. Low irritation and comedogenic risk. No significant safety concerns reported in cosmetic formulations.
Research notes
Structural similarity to natural ceramides suggests barrier-repair benefits, but direct clinical studies on this specific compound are limited. Most evidence is extrapolated from ceramide research.
Common label clues
- Typical concentration
- 0.1% to 2%
- Regulatory status
- Approved for use in cosmetics in the EU, US, and other major markets. No specific restrictions as of 2025.
- Common uses
- Moisturizers, Anti-aging creams, Barrier repair balms
- Environmental note
- Synthesized in a lab, so it avoids the environmental impact of harvesting natural ceramides from plant or animal sources.
Good to know
- Often listed near the middle or end of an ingredient list because it's effective at low concentrations.
- Pairs well with niacinamide and hyaluronic acid for enhanced barrier support.
