Ingredient review
DHA/DPA/Oleic/Palmitic Triglyceride
INCI: DOCOSAHEXENOIC/DOCOSAPENTENOIC/OLEIC/PALMITIC TRIGLYCERIDE
A nourishing blend of omega fatty acids that helps soften skin and strengthen the moisture barrier without feeling greasy.
In plain English
This ingredient is a fancy name for a mixture of healthy fats (omega-3s and omega-9s) attached to glycerin. In skincare, it works like a gentle, non-greasy oil that sinks into the skin to help it stay soft, smooth, and hydrated. It's especially good for dry or mature skin because it supports the skin's natural barrier, which keeps moisture in and irritants out.

Quick decision guide
Useful, but context matters
DHA/DPA/Oleic/Palmitic Triglyceride 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 DHA/DPA/Oleic/Palmitic Triglyceride.
- 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 triglyceride made by combining glycerin with four fatty acids: docosahexaenoic acid (DHA, an omega-3), docosapentaenoic acid (DPA, another omega-3), oleic acid (an omega-9), and palmitic acid (a saturated fat). It is typically derived from marine oils or algae.
How it works
When applied to the skin, it spreads easily and fills the gaps between skin cells, reinforcing the lipid barrier. This reduces water loss (called transepidermal water loss, or TEWL) and keeps the skin feeling supple. The omega-3s also have mild anti-inflammatory properties, which can help calm redness or irritation.
Pros
Lightweight yet nourishing
Unlike some heavy oils, this triglyceride absorbs quickly and leaves skin soft without a greasy residue, making it comfortable for daily use.
Barrier-supporting omega-3s
The DHA and DPA components provide omega-3 fatty acids that help reinforce the skin's moisture barrier and may reduce inflammation.
Cons and cautions
Not ideal for very oily skin
In high concentrations, it could feel too rich for those with naturally oily or acne-prone skin, potentially contributing to clogged pores.
Sustainability concerns
If derived from fish or marine oils, the ingredient may not align with vegan or eco-conscious preferences unless sourced from algae or certified sustainable fisheries.
Best for
- People with dry, dehydrated, or mature skin looking for a nourishing emollient
- Those with sensitive or easily irritated skin who want a gentle moisturizer
Use caution if
- Individuals with very oily or acne-prone skin may prefer lighter oils like squalane or grapeseed oil
Usage tips
Safety summary
Considered safe for cosmetic use with a low risk of irritation or allergic reactions. It is non-toxic and non-sensitizing at typical concentrations. As with any oil-based ingredient, those with very oily skin should monitor their skin's response.
Research notes
Omega-3 fatty acids like DHA and DPA are well-studied for their anti-inflammatory and barrier-supporting properties in skin. However, specific studies on this exact triglyceride blend are limited; most evidence comes from research on individual fatty acids and their effects on skin health.
Common label clues
- Typical concentration
- 1% to 10% in leave-on products
- Regulatory status
- Approved for use in cosmetics globally, including by the EU CosIng database and the US FDA as a skin conditioning agent.
- Common uses
- Moisturizers, Anti-aging creams, Lip balms, Body lotions
- Environmental note
- If derived from marine sources, look for products that specify algae-based or sustainably sourced fish oil to reduce environmental impact.
Good to know
- This ingredient is often used as a more stable and less greasy alternative to pure fish oil in skincare.
- It is generally considered non-comedogenic for most skin types, but patch test if you are prone to breakouts.
