The quality or origin of petrolatum is only known when disclosed by the brand.

Other benefits of occlusives include protecting your skin against infection or allergies.

Petrolatum may not be safe for fungal-acne.

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

Nutmeg, palm kernel oil, and coconut oil all contain this ingredient naturally.

The comedogenic rating of this ingredient depends on the concentration. Lower amounts results in a lower rating.

Isopropyl Myristate may not be fungal acne safe. It can potentially worsen acne prone skin.

Studies found this ingredient did not irritate skin in concentrations below 15%.

UVB (290-320 nm) rays emit more energy than UVA rays. They are capable of damaging DNA, causing sunburns and are thought to be linked to skin cancer.

The state of Hawaii has banned sunscreens containing octinoxate due to its potential impact on coral reefs. More research is needed to bridge gaps in this research. The European Union allows higher levels of octinoxate in sunscreens than the US and Australia.

Ethylhexyl Methoxycinnamate is oil soluble. It is not stable and may lose efficacy when exposed to sunlight.

Studies have found that avobenzone becomes ineffective when exposed to UV light (it is not photostable; meaning that it breaks down in sunlight). Because of this, formulations that include avobenzone will usually contain stabilizers such as octocrylene.

However, some modern formulations (looking at you, EU!) are able to stabilize avobenzone by coating the molecules.

Avobenzone does not protect against the UV-B range, so it's important to check that the sunscreen you're using contains other UV filters that do!

The highest concentration of avobenzone permitted is 3% in the US, and 5% in the EU.

UV absorbers are an agent that absorbs UV rays. They protect your skin by using chemical reactions to convert UV rays into heat and energy.

UV rays are a form of electromagnetic radiation from the sun. Other sources include tanning beds and welding torches. Radiation is the emission of energy. UV Rays are divided into 3 groups. UVA (320-400 nm) contains the least amount of energy. They are linked to long term skin damage such as wrinkles and hyperpigmentation. UVB (290-320 nm) rays emit more energy than UVA rays. They are capable of damaging DNA in skin cells. UVB causes sunburns and are thought to be linked to skin cancer. UVC (200-280 nm) contains the highest amount of energy. Our ozone blocks UVC. UVC can also originate from welding torches, mercury lamps, and sanitizing bulbs.

Ongoing research is looking into whether oxybenzone causes skin irritation and sensitivity. However, it has been shown to trigger contact dermatitis in some studies.

Oxybenzone is allowed in certain concentrations by many countries. It is allowed up to 6% in the US, and Canada, 5% in Japan, and 10% in Australia. Other countries and regions of the US have banned this ingredient to protect coral reefs and marine ecosystems. These places include Hawaii, Key West, US Virgin Islands, marine parks in Thailand, Aruba, and Palau.

The EU currently allows the following maximum concentrations:

Studies show conflicting results about oxybenzone being absorbed into the human body. The Swedish Research Institute has advised careful use of this ingredient by pregnant women and children. We always recommend speaking with a professional if you have concerns about this ingredient and your health.

It is highly photostable and helps prevent the photodegration of other sunscreen ingredients such as avobenzone.

Bemotrizinol is not approved in the US but is allowed in the EU, Australia, and Asia.

In fact, it is the most effective UV absorber at maximum concentration (measured by SPF) permitted by in the EU.

It is oil-soluble.

Tocopheryl Acetate is commonly found in both skincare and dietary supplements.

“Aroma is a term for ingredient labeling used to identify that a product contains a material or combination of materials normally added to a cosmetic to produce or to mask a particular flavor.”

Alcohol comes in many different forms. Different types of alcohol will have different effects on skin. This ingredient is an astringent alcohol.

Using high concentrations of these alcohols are drying on the skin. They may strip away your skin's natural oils and even damage your skin barrier. Astringent alcohols may also irritate skin.

Other types of astringent alcohols include:

According to the National Rosacea Society based in the US, you should be mindful of products with these alcohols in the top half of ingredients.

Any type of sanitizing product will have high amounts of alcohol to help kill bacteria and viruses.

Solvents are used to keep ingredients together in a product. They can help dissolve ingredients to stable bases or help evenly distribute ingredients throughout the product.

Due to its fragrance, Benzyl Benzoate can be sensitizing and may cause contact dermatitis. It is a known EU allergen. We recommend speaking with a professional if you have any concerns.

Benzyl Benzoate can be naturally found in cranberries and peaches.

As an AHA, Citric Acid removes the top layer of skin cells from the newer layer of skin underneath. This helps skin to remove dark spots and look more even.

Potassium Sorbate, another commonly-used preservative, is the potassium salt of Sorbic Acid.

Sorbic Acid may worsen eczema. We recommend speaking with a professional if you have any concerns.

Potassium sorbate and sorbic acid can be found in baked goods, cheeses, dried meats, dried fruit, ice cream, pickles, wine, yogurt, and more.

Ascorbyl Tetraisopalmitate interferes with the process of skin darkening, helping to reduce hyperpigmentation. It also encourages the skin to produce more collagen.

As an antioxidant, it helps fight free-radicals. Free-radicals are molecules that may damage your skin cells.

One study found Ascorbyl Tetraisopalmitate to degrade in sunlight, but is stabilized when conbined with acetyl zingerone.

Vanillism is the term of contact-dermatitis associated with the vanilla plant. The sap of the vanilla plant triggers skin irritation, swelling, and redness.
