Silica is present naturally within the skin during collagen production and when reducing inflammation.

Fun fact: Betaine is naturally created in the skin and body. The kind found within cosmetic products can be either plant-derived or synthetic.

Stearic acid may also be used to enhance the texture of products. It can add volume and stabilize ingredients such as water and oil. This can help water and oil ingredients from separating.

Sources of stearic acid include animal or vegetable fats/oils such as coconut or shea. It can be naturally found in butter, cocoa butter, shea butter, vegetable fats, and animal tallow.

This ingredient may not be Malassezia folliculitis, or fungal-acne safe.

Caprylic Triglyceride is made by combining glycerin with coconut oil, forming a clear liquid.

While there is an assumption Caprylic Triglyceride can clog pores due to it being derived from coconut oil, there is no research supporting this.

Arginine isn't fungal acne safe when used in the presence of other lipids (fats, fatty acids, oils, esters, etc). Oils and fats occur naturally within the skin, so take caution when using Arginine if you're prone to fungal acne.

One component, glabridin, has extra potent antioxidant and soothing properties. It has also been found to block pigmentation from UVB rays in guinea pigs.

Licorice Root also contains a flavonoid. Flavonoids are a natural substance from in plants. Flavonoids also have antioxidant properties.

Another component, glycyrrhizin, has been found to have anti-inflammatory and antimicrobial benefits. This may make licorice root extract effective at treating acne. However, more research is needed to support this.

Liquiritin is one of the flavone compounds found in licorice. It has been found to help lighten skin by preventing tyrosinase from reacting with tyrosine. When the two react, protein is converted to melanin. Melanin is the substance in your body that gives your features pigmentation.

Licorice root is native to Southern Europe and Asia. It has been used in traditional Chinese medicine to help with respiratory issues.

With modern production, nano-scale or fine-grade titanium dioxide can be easily produced for cosmetics. In sunscreen, titanium dioxide absorbs UV light. Our skin is not able to absorb Titanium dioxide, even nanoparticles.

Titanium itself is the 9th most common element in the Earth's crust. Titanium dioxide is formed when oxygen is introduced and can be found in ores, dust, sand, and soil.

Pure titanium dioxide is a white powder that is used in many products to add or change color.

Tromethamine helps balance the pH level of a product. Normal pH level of skin is slightly acidic (~4.75-5.5). The acidity of our skin is maintained by our glands and skin biome. Being slightly acidic allows our skin to create an "acid mantle". This acid mantle is a thin barrier that protects our skin from bacteria and contaminants.

Oral Tromethanmine is an anti-inflammatory drug but plays the role of masking, adding fragrance, and/or balancing pH in skincare.

Biotin is water-soluble. It can be found in foods such as fish, eggs, dairy, nuts, and meat. Vitamin H stands for "haar" and "haut". These are the German words for hair and skin.

Vitamin C is best used for brightening skin. It improves dark spots, acne scars, and hyperpigmentation. This is because it blocks the process of skin darkening when exposed to UV.

Your skin uses vitamin C to build collagen. Collagen is one key component in having a strong skin barrier and plump skin. Vitamin C also plays a role in regulating collagen, thus making it effective in improving wrinkles and fine lines.

Ascorbic acid shows potent antioxidant activity. As an antioxidant, it helps fight free-radicals. Free-radicals are molecules that may damage your skin cells. These antioxidants also protect skin against UV damage.

The best formulations include Vitamin E and/or ferulic acid. These two ingredients help stabilize and provide a boost in the benefits of ascorbic acid. This is because ascorbic acid becomes unstable when exposed to UV and air. In fact, you can tell your ascorbic acid has oxidized when it turns an orange-yellow color.

Ascorbic acid is generally compatible with other ingredients. However, using ascorbic acid with other active ingredients might cause irritation. Two ingredients: copper ions and benzoyl peroxide, will inactivate ascorbic acid completely.

There are often claims that Vitamin E can reduce/prevent scarring, but these claims haven't been confirmed by scientific research.

In vivo studies show folic acid to decrease UV-C induced DNA damage on human fibroblasts. This is because folic acid is effective at rejoining breaks in the fibroblast DNA. It is believed folic acid may play a role in reducing UV-B damage as well. While the mechanisms are unknown, it is believed folic acid plays a role in disrupting the DNA damage process.

Studies show using moisturizers rich in folic acid led to increased hydration of the skin. Hydrated skin is essential for collagen and elastin, or for keeping skin plump. One study found a reduction in wrinkles from using folic acid creams.

Foods rich in folic acid include leafy vegetables, beans, peanuts, fresh fruit, and eggs.

The term 'citral' is a collective term for two geometric isomers: geranial/Citral A and neral/Citral B.

Limonene acts as an antioxidant, meaning it helps neutralize free radicals.

When exposed to air, oxidized limonene may sensitize the skin. Because of this, limonene is often avoided by people with sensitive skin.
