Ingredient review
Lysophosphatidylcholynyl Chlorin E6
INCI: LYSOPHOSPHATIDYLCHOLINYLCHLORIN E6
An experimental ingredient with potential for light-activated delivery, but very limited safety and efficacy data in everyday skincare.
In plain English
This is a lab-made molecule that pairs a fat-like substance (lysophosphatidylcholine) with a green pigment derived from chlorophyll (chlorin e6). The idea is that the fat part helps it stick to skin cells, while the pigment part can be activated by light to release ingredients or produce effects. However, this is still very much in the research phase and is not commonly found in consumer products. There is not enough information to say it is safe or effective for routine use.

Quick decision guide
Read the cautions before using
Lysophosphatidylcholynyl Chlorin E6 can be useful, but watch for some irritation potential.
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 Lysophosphatidylcholynyl Chlorin E6.
- 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
moderateCan bother some users, especially with frequent use, damaged skin, or strong companion ingredients.
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
A semi-synthetic conjugate of lysophosphatidylcholine (a phospholipid) and chlorin e6 (a chlorophyll derivative). It is designed to combine the cell-membrane affinity of the phospholipid with the light-sensitive properties of chlorin e6.
How it works
In a cosmetic product, the lysophosphatidylcholine portion may help the molecule bind to skin cell membranes, while the chlorin e6 portion can absorb light energy. This light absorption could theoretically trigger the release of other ingredients or generate reactive oxygen species, but this mechanism is not established for safe cosmetic use.
Pros
Novel delivery concept
The phospholipid part may help the ingredient bind to skin cell membranes, potentially improving the delivery of other active ingredients in experimental formulations.
Light-responsive potential
The chlorin e6 component can absorb light, which could theoretically be used to trigger ingredient release or other effects in controlled settings.
Cons and cautions
Lack of safety data
There are very few published studies on this specific molecule in cosmetic use, so its safety profile for everyday skincare is unknown.
Potential phototoxicity risk
The chlorin e6 part is a photosensitizer, meaning it could cause skin irritation or damage if the product is used and then exposed to light without proper protection.
Not consumer-ready
This ingredient is not commonly found in over-the-counter products and is mostly used in experimental or professional settings.
Best for
- Researchers studying light-activated delivery systems
- Formulators developing experimental products with professional oversight
Use caution if
- Anyone looking for a proven, safe skincare ingredient
- People with sensitive skin or a history of photosensitivity
Usage tips
Safety summary
Safety data for lysophosphatidylcholynyl chlorin e6 in cosmetics is extremely limited. The chlorin e6 component is a known photosensitizer, which raises concerns about phototoxicity and irritation. Without robust human studies, it is not recommended for routine consumer use.
Research notes
Research on this specific molecule is sparse. Most studies focus on chlorin e6 in medical photodynamic therapy, not cosmetic applications. The combination with lysophosphatidylcholine is novel but lacks peer-reviewed evidence for safety or efficacy in skincare.
Common label clues
- Typical concentration
- Very low (typically under 0.1%)
- Regulatory status
- Not specifically regulated as a cosmetic ingredient in most regions; may be considered a new ingredient requiring safety assessment under EU or FDA guidelines.
- Common uses
- Experimental serums, Light-activated treatments
- Environmental note
- No specific environmental data available for this compound; its production likely involves synthetic chemistry and may generate chemical waste.
Good to know
- Chlorin e6 is a derivative of chlorophyll and is sometimes studied in photodynamic therapy for medical use, not for routine skincare.
- Lysophosphatidylcholine is a natural phospholipid found in cell membranes, but when combined with chlorin e6, the safety profile changes.
