As an antioxidant, Calophyllum Inophyllum Seed Oil may also slow down the signs of aging. Antioxidants help fight unstable free-radical molecules.

These molecules may damage your skin cells and speed up aging. By helping to stabilize these molecules, antioxidants may help slow the signs of aging.

A study from 2015 found Tamanu oil to have antibacterial and anti-inflammatory properties.

Another study from 2009 found Tamanu Oil to help absorb UV rays. However, this should not replace your sunscreen.

Due to the fatty acid content, this ingredient may not be fungal-acne safe.

A 14 day human study found its moisturizing performance matched olive oil and tested as mild/low irritation on skin tissue.

It also showed gentle anti-inflammatory + antioxidant activity, plus the ability to stop Staphylococcus aureus (a bacteria tied to breakouts and eczema flares) from sticking to skin.

The concentration for this oil is flexible and can range from a few percent in serums up to 100% as a facial oil.

Since this ingredient is a triglyceride oil loaded with fatty acids that Malassezia can feed on, it may not be fungal acne safe.

Allergy-wise, the risk is low. Despite having the nicknames "Inca peanut" or "mountain peanut", this ingredient is not actually a peanut or tree nut. However, allergy to the seeds does exist so patch test if your skin is reactive.

The composition (and benefits) of the extract will depend on which part of the plant it comes from.

This ingredient may help soothe your skin by reducing inflammation. Emerging studies show it inhibits nitrous oxide production safely, therefore reducing inflammation.

Marigolds have been used in traditional medicine throughout Asia and Europe.

Unlike other plant oils, jojoba wax doesn't easily penetrate skin. It mostly works in the uppermost layers as an emollient. This just means it forms a light barrier on the skin to help retain moisture.

Formulations with jojoba esters up to 90% reduced transepidermal water loss (TEWL) and increased barrier recovery by 81% (outperforming bisabolol at 47%).

Besides barrier support, the science also suggests jojoba to have anti-inflammatory effects and potential applications for skin infections, aging, and wound healing.

Fun fact: Indigenous cultures have used jojoba as a moisturizer and to help treat burns for centuries.

Fungal acne: The Malassezia yeast is known to metabolize fatty acids in the C11-24 range and jojoba's dominant fatty acid components fall into this range. This ingredient may not be fungal acne safe.
