Works for
Anti-oxidation
This product contains antioxidants (3-o-ethyl ascorbic acid) that might be able to help neutralize free radicals in skin to lessen the damage it gets from the UV light (sun). There is not enough evidence to confirm their effectiveness in skin though.
A vitamin C derivative that is more stable but less potent than pure form of vitamin C. Can help neutralize free radicals and help reduce hyperpigmentation, but the required concentration is likely to be much higher than for the pure form of vitamin C, limiting the ingredient's effectiveness in products
A plant extract that might help neutralize free radicals in skin, but research on its effectiveness is lacking
A plant extract that helps attract water to the upper layer of the skin. It might be helpful in neutralizing free radicals in skin, but is less potent than the extract from the seeds
Being a lipid soluble form of vitamin C, it is more stable than ascorbic acid, but still degrades quickly and needs to be stabilized in a formulation with another ingredient. It is claimed to penetrate skin better than pure vitamin C and have the the similar benefits, but solid studies of its effectiveness are lacking. Is likely to require a higher concentration in a product than pure vitamin C to be effective. It might be able to help reduce pore clogging.
Pure form of vitamin E. Can help moisturise and protect the skin from free radicals. Often used to help stabilise other ingredients or the formula itself
A polyhydroxy acid (PHA) that helps shed the dead cells from the skin surface revealing smoother skin. Is believed to be genter than AHAs. It helps attract water to the upper layer of the skin and can stimulate production of skin's own hyaluronic acid resulting in improved hydration levels. It has been shown to be helpful against acne and clogged pores if used consistently (e.g over a period of 12 weeks) in high enough concentration. It can help reduce fine lines and wrinkles and improve skin tone with long-term application. Can help neutralize free radicals
A great emollient. Contains vitamin E (tocopherol) which may give it some anti-oxidant properties. Can contain volatile compounds and can be irritating
Can be helpful in reducing inflammation in skin, including inflamed acne. It can be irritating
An emollient that helps soften the upper layer of the skin. Might have some weak anti-oxidant properties

This product can help improve hydration of the skin with the two types of ingredients.
The first type is called “humectants”:
these ingredients help attract water.
When humectants are on the surface of the skin, they “pull in” the moisture from the outside environment, or from
within deeper layers of the skin. The following ingredients in this product do the job:
glycerin, sodium hyaluronate.
This product also contains ingredients called “occlusives”. They help reduce the speed with which our skin loses moisture to the outside environment. These ingredients also help soften the upper layer of the skin, so it feels less tight and nicer to the touch. The following ingredients in this product do the job: caprylic/capric triglyceride, helianthus annuus extract.
Helps soften the upper layer of the skin
One of the best moisturizing ingredients. Attracts water into the upper layer of the skin
A good mix of fatty acids that forms a protective layer on the skin. Improves the shelf life of products. Derived from coconut and glycerin
One of the best moisturizing ingredients. Naturally present in skin. It attracts water to the upper layer of the skin working as a humectant
Helps soften the upper layer of the skin
A plant extract that helps attract water to the upper layer of the skin. It might be helpful in neutralizing free radicals in skin, but is less potent than the extract from the seeds
A plant oil that helps soften the upper layer of the skin. Is unlikely to be helpful in restoring skin barrier function due to the low content of linoleic acid
Helps preserve products and creates a nice product texture
Used to preserve products, dissolve other ingredients and create a nice product texture
A great emollient. Contains vitamin E (tocopherol) which may give it some anti-oxidant properties. Can contain volatile compounds and can be irritating
Softens the upper layer of skin and helps restore the healthy skin barrier. Has shown to help calm down inflammation in skin. It is a stable oil, meaning that it retains its properties even when exposed to air.
