Fish Lecithin Oil
INCI: PISCUM LECUR OIL
Fish Lecithin Oil is a nourishing emollient that helps soften and condition skin, but may be too rich for oily or acne-prone skin.
In plain English
Fish Lecithin Oil is a fatty substance extracted from fish, similar to the lecithin found in eggs or soy. In skincare, it works like a moisturizing oil, helping to soften and smooth the skin's surface. It also contains phospholipids, which are natural components of skin cells, so it can support the skin's barrier function. Think of it as a gentle, nutrient-rich oil that helps your skin feel supple and hydrated.

What it is
Fish Lecithin Oil is a natural oil obtained from fish, rich in phospholipids and essential fatty acids. It is a byproduct of fish processing and is refined for cosmetic use.
How it works
It acts as an emollient, filling in gaps between skin cells to create a smoother surface. The phospholipids can also help reinforce the skin's natural barrier, reducing moisture loss and protecting against environmental stressors.
Pros
Rich in skin-identical lipids
Contains phospholipids that mimic natural skin components, helping to strengthen the moisture barrier and keep skin resilient.
Good for dry, flaky skin
Provides intense emollience that smooths rough patches and leaves skin feeling soft and nourished.
Cons and cautions
Potential for clogged pores
Its rich, oily nature can be too heavy for oily or acne-prone skin, potentially leading to breakouts.
Not vegan-friendly
Derived from fish, so it is not suitable for those following a vegan lifestyle or avoiding animal products.
Best for
- People with dry or mature skin needing extra moisture
- Those looking for natural emollients to support skin barrier
Use caution if
- Individuals with fish allergies
- Vegans and those avoiding animal-derived ingredients
- Oily or acne-prone skin may find it too heavy
Usage tips
Safety summary
Generally safe for topical use in cosmetics. The main concerns are potential comedogenicity and allergenicity for fish-sensitive individuals. Always patch test.
