Capsicum Extract
INCI: Capsicum Frutescens Fruit Extract
A CO2 extract of hot pepper fruit rich in capsaicinoids and carotenoids, used for warming pain-relief formulas and lip plumping.
Overview
Capsicum extract is a CO2 extract of hot pepper fruit — the same family that gives you cayenne and chili peppers. The supercritical extraction pulls out the bioactive compounds without the harsh solvents, leaving you with a concentrated, deep red oil rich in capsaicinoids (3-3.2%, mainly capsaicin and dihydrocapsaicin) and carotenoids (0.6-1%, including beta-carotene and capsanthin).
The beautiful red colour comes from those carotenoids, and it will tint your finished product. The warming sensation comes from the capsaicinoids, which interact with TRPV1 receptors in the skin to create a localised heat and increased blood flow. This is the same mechanism behind capsaicin pain-relief patches and lip plumping glosses.
This is a potent active. A little goes a long way, and there are real safety boundaries to respect. It is not a casual “add a drop and see” ingredient.
What it does in a formula
Capsaicinoids trigger local vasodilation — blood rushes to the area, creating warmth, mild redness, and a tingling or plumping effect. In pain-relief balms and salves, this warming action helps with chronic joint pain, arthritis, rheumatism, and muscular stiffness. In lip products, the same mechanism produces the temporary plumping effect that makes lips look fuller.
The carotenoid content also provides some antioxidant benefit and contributes the rich red pigmentation. If you are using this in a lip balm or gloss, expect a warm reddish tint alongside the plumping action.
How to use
Add to the oil phase. Capsicum extract is lipophilic and blends readily into oils, butters, and waxes. It can tolerate standard oil-phase processing temperatures, but keeping it below 70 C helps preserve the carotenoid colour.
Usage rates by product type:
- Lip plumping balms and glosses: 0.1-0.3%
- Pain-relief balms and salves (body): 0.3-0.5%
- Warming muscle rubs: 0.3-0.5%
- Scalp stimulation oils: 0.1-0.2%
The maximum recommended dermal usage is 0.5%. Stay well within that limit, especially for your first batch — you can always increase on the next round.
Best for / Worst for
Best for: lip plumping products, chronic pain-relief balms (arthritis, rheumatism), warming muscle rubs, scalp stimulation treatments, body products targeting circulation.
Worst for: facial skincare (except lips), eye-area products (never), sensitive or irritated skin, broken or damaged skin, products for use during pregnancy, children’s products, leave-on products for large body areas at high concentration.
Common pitfalls
Using too much on your first attempt. Start at 0.1% and test on a small skin area. Capsaicin is dose-dependent — 0.5% feels dramatically different from 0.1%. You cannot undo the burn once the product is applied, so be conservative.
Getting it near the eyes. This is a serious safety issue. Even trace amounts transferred by fingers can cause intense burning and tearing. Wash hands thoroughly after handling, and never use this ingredient in any eye-area product.
Forgetting it stains everything. The deep red colour from carotenoids will stain silicone spatulas, plastic containers, and light-coloured fabrics. Use stainless steel or glass for mixing, and wipe spills immediately.
Assuming it is safe for all skin. Capsicum extract is contraindicated on broken, irritated, or sunburned skin and should be avoided during pregnancy. Always include a clear warning label on finished products.
Substitutes
- Ginger CO2 extract — provides a milder warming sensation without the intense capsaicin heat. Better for sensitive users.
- Cinnamon bark CO2 extract — warming and stimulating, but through a different mechanism. Can also be irritating, so patch test.
- Menthol crystals — gives a cooling-then-warming sensation rather than pure heat. Common in muscle rubs as an alternative approach.
- Vanilla oleoresin (for lip tint only) — if you want the red-tinted lip look without the plumping heat, a vanillin-free oleoresin adds colour without capsaicinoids.
