It’s a 10 Blow Dry Miracle Blow Dry Styling Balm

It is also an emollient. Emollients help soften the skin and prevent water loss. Silicones create a silky texture in products. D5 helps other ingredients become more spreadable.

Studies show D5 is safe to use in skincare products. We recommend speaking with a skincare professional if you have concerns.

Dimethicone comes in different viscosities:

Depending on the viscosity, dimethicone has different properties.

Ingredients lists don't always show which type is used, so we recommend reaching out to the brand if you have questions about the viscosity.

This ingredient is unlikely to cause irritation because it does not get absorbed into skin. However, people with silicone allergies should be careful about using this ingredient.

Note: Dimethicone may contribute to pilling. This is because it is not oil or water soluble, so pilling may occur when layered with products. When mixed with heavy oils in a formula, the outcome is also quite greasy.

The fatty acids found in sunflower seeds include (from highest amount to least): linoleic acid, myristic acid, palmitic acid, stearic acid, arachidic acid, oleic acid, and linolenic acid.

These fatty acids hydrate your skin. Emollients create a film on the skin to prevent moisture from escaping.

Its soothing ability comes from a variety of compounds including biflavones, a type of flavonoid. Studies show gingko biloba has strong anti-inflammatory properties.

Fun fact: This tree is native to China and has been used in traditional Chinese medicine for thousands of years.

As a humectant, hydrolyzed keratin helps draw moisture from the air to your hair and skin. This helps keep your skin and hair hydrated.

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.

It can also form a thin protective film on skin. One study found that a formula using this polymer helped slow down how quickly other ingredients (like DEET) were absorbed through skin.

A 2024 study of over 1,300 patients confirmed that sensitization to this ingredient is rare. It is also non-mutagenic and has a clean track record.

This ingredient is sourced from plant-based oils like soybean or rapeseed.

Clinical studies found no signs of irritation from this ingredient.

Since Isostearic Acid is an 18-carbon fatty acid, it is in the range that Malassezia can feed on. This ingredient may not be fungal acne safe.

You might have seen sources that this ingredient is comedogenic. This is because the original comedogenic tests (on rabbit ears, which are more sensitive than human skin) tested

The Kligman/Fulton rabbit ear papers actually tested the ester, Isopropyl Isostearate and not Isostearic acid itself. There has been no comedogenic testing done on this ingredient, but it may be worth patch testing if you have acne-prone skin.

According to EU CosIng, this ingredient helps soften skin, keep oil and water stay mixed, and thickens products.

Hydrogenated castor oil at 30% did not trigger a positive patch-test reaction and is well-tolerated.

Since this ingredient is based on an 18-carbon fatty acid, it falls into the chain-length range that Malassezia can feed on and may not be fungal acne safe.

It is typically used at very low levels in cosmetics, with most formulations using 0.0125% or less (well below its approved maximum).

In the EU, IPBC concentration limits are set at 0.02% in rinse-off products and 0.01% in leave-on products.

Though IPBC is a relatively uncommon contact allergen, patch testing studies show positive reaction rates ranging from 0.3%-0.9% of patients tested. This is still quite low compared to preservatives like methylisothiazolinone which sits at around 4-5%.

Researchers note that existing iodine sensitives or rubber allergies may be the cause of this as IPBC shares a structure with both thiuram (used in rubber) and iodine.

Be sure to patch test if you are unsure and speak with a medical professional about using this ingredient.

Your skin makes glycerin on its own (mostly from sebaceous oil breakdown) and shuttles it to your outermost layer of skin, or your epidermis, via aquaporin-3.

Aquaporin-3 is a transporter that is essential for normal skin hydration, elasticity, and repair. Interestingly, mice lacking in AQP3 have dry and less elastic skin that can be fully corrected with glycerin.

This ingredient is non-irritating, plays well with almost every ingredient, and works across all skin types. Typical use is anywhere between 3-10% but can go up to 79% in some leave-on products.

Just know very high concentrations (>40%) can feel tacky in low humidity.

Glycerin is the name for this ingredient in American English. British English uses Glycerol/Glycerine.

Your skin has a natural pH and acid mantle. This acid mantle helps prevent harmful bacteria from breaking through. The acid mantle also helps keep your skin hydrated.

"Alkaline" refers to a high pH level. A low pH level would be considered acidic.

Though this ingredient works well with most skin types, some people with sensitive skin may experience a reaction such as allergic rashes, closed comedones, or itchiness.

DMDM Hydantoin is approved for use in cosmetics all around the world.
In the EU, this ingredient is allowed in personal products up to 0.6 percent.

You might have heard of the class-action lawsuit about it causing hair loss. According to chemists, there has not been a link found between this ingredient and hair loss.

The Hydantoin part of this ingredient is created by reacting glycolic acid and urea.

You can check out alternatives to Dmdm Hydantoin:
phenoxyethanol, potassium sorbate, and sodium benzoate.

On top of that, this ingredient can counteract the effects of hard water by binding to the minerals in it.

One thing worth knowing is that Disodium EDTA has been shown to be a mild penetration enhancer. It can help other ingredients absorb into skin more effectively which can be a double-edged sword (great for actives, but can also make the active too strong if you have sensitive skin).

Clinical patch testing showed no significant skin irritation at typical use concentrations and minimal dermal absorption.

You'll most likely see this ingredient near the end of an ingredient list. It's typically found in concentrations less than 1%.

For instance, Habanolide is a proprietary trade name for a specific aroma chemical. When used as a fragrance ingredient in cosmetics, most aroma chemicals fall under the broad labeling category of “FRAGRANCE” or “PARFUM” according to EU and US regulations.

The term 'parfum' or 'fragrance' is not regulated in many countries. In many cases, it is up to the brand to define this term.

For instance, many brands choose to label themselves as "fragrance-free" because they are not using synthetic fragrances. However, their products may still contain ingredients such as essential oils that are considered a fragrance by INCI standards.

One example is Calendula flower extract. Calendula is an essential oil that still imparts a scent or 'fragrance'.

Depending on the blend, the ingredients in the mixture can cause allergies and sensitivities on the skin. Some ingredients that are known EU allergens include linalool and citronellol.

Parfum can also be used to mask or cover an unpleasant scent.

The bottom line is: not all fragrances/parfum/ingredients are created equally. If you are worried about fragrances, we recommend taking a closer look at an ingredient. And of course, we always recommend speaking with a professional.
