Due to its large molecular size, this ingredient is not absorbed into the skin.

Ethylhexylglycerin is created from glycerin. It is a multitasker ingredient that:

The CIR Expert Panel found minimal skin absorption or sensitization of any kind in a safety assessment. Though this ingredient is considered well-tolerated, a small number of cases of allergic dermatitis have been published since 2002. Just be sure to patch test if you are unsure.

Water. It's the most common cosmetic ingredient of all. You'll usually see it at the top of ingredient lists, meaning that it makes up the largest part of the product.

Pentaerythrityl Tetra-Di-T-Butyl Hydroxyhydrocinnamate (long name, huh?) is a synthetic antioxidant.

It is used to help stabilize other antioxidants or prevent the color from changing in a product.

Butylene Glycol (or BG) is used within cosmetic products for a few different reasons:

Overall, Butylene Glycol is a safe and well-rounded ingredient that works well with other ingredients.

Melia Azadirachta Leaf Extract is extract from the neem plant.

The leaves of this tree contain flavonoids and polyphenols. These two compounds are antioxidants, anti-inflammatory, and antibacterial. Further research is needed as to their effects when applied on skin.

Melia Azadirachta Flower Extract is from the Neem tree. Neem trees originate from India.

Melia Azadirachta Flower Extract contains antioxidants. Antioxidants help fight free-radicals. Free-radicals are molecules that may damage your skin cells, such as pollution.

Coccinia Indica Fruit Extract is also known as Ivy Gourd Fruit Extract. It has skin conditioning properties.

Mentha Piperita Leaf Extract is extract from peppermint leaves. It has a "cooling" sensory feel depending on what compounds are found in the extract.

Peppermint leaves contain polyphenols that antioxidant activity. In-vitro studies show anti-inflammatory and antimicrobial activity against some bacteria and fungi.

This ingredient comes from eggplant (or aubergine). It has skin conditioning properties due to its abundance of antioxidants like Chlorogenic Acid, Caffeic Acid, and Nasunin.

Nasunin is the pigment concentrated in the purple peel and has demonstrated the abilityu to neutralize free radicals and bind excess iron in lab studies.

Ocimum Sanctum Leaf Extract comes from the Holy Basil plant. Holy Basil is native to India.

Holy Basil is rich in antioxidants due to its high romarinic acid, ferulic acid, and rutin content. This gives it skin brightening and soothing properties.

Curcuma Longa Root Extract is from the spice, turmeric. Besides being a healthy and delicious spice, turmeric also has plenty of skincare benefits. It has anti-inflammatory, antioxidant, and anti-microbial properties.

Turmeric contains curcumin, an antioxidant. Antioxidants help neutralize unstable free-radical molecules. Free-radical molecules may damage your skin's cells and DNA. Curcumin may help with anti-aging.

Corallina Officinalis Extract is from the red seaweed, Corallina Officinalis. This seaweed is found all over the world but is most common in the rocky shores of Great Britain and Ireland.

Corallina Officinalis Extract contains antioxidant and emollient properties.

Moringa Oleifera Seed Oil is the oil expressed from the seeds of Moringa oleifera plant. It is more commonly known as Moringa seed oil.

Moringa seeds have antioxidant, anti-inflammatory, and skin hydrating properties. These seeds are rich in oils, proteins, monounsaturated fats, and tocopherols.

Magnesium Ascorbyl Phosphate (MAP) is a water-soluble form of Vitamin C. It is used in skincare because it tends to be more formulation friendly than pure vitamin C (ascorbic acid).

According to research, MAP has three major benefits:

Citric Acid is an alpha hydroxy acid (AHA) naturally found in citrus fruits like oranges, lemons, and limes.

Like other AHAs, citric acid can exfoliate skin by breaking down the bonds that hold dead skin cells together. This helps reveal smoother and brighter skin underneath.

Betaine Salicylate is considered a salicylic acid alternative.
