1,2-Hexanediol is a synthetic liquid and another multi-functional powerhouse.Â
It is a:
- Humectant, drawing moisture into the skin
- Emollient, helping to soften skin
- Solvent, dispersing and stabilizing formulas
- Preservative booster, enhancing the antimicrobial activity of other preservativesÂ
Adenosine is in every living organism. It is one of four components in nucleic acids that helps store our DNA.
Adenosine has many benefits when used. These benefits include hydrating the skin, smoothing skin, and reducing wrinkles. Once applied, adenosine increases collagen production. It also helps with improving firmness and tissue repair.
Studies have found adenosine may also help with wound healing.
In skincare products, Adenosine is usually derived from yeast.

Like many other plant extracts, red onion is loaded with antioxidants and nutrients. The red color of the onion comes from its high anthocyanin content - and anthocyanin is a potent antioxidant.
Besides being rich in antioxidants, red onions also contain sulfur, sugars, Vitamin C, and biotin.
A study from 2018 found onion extract to be just as effective as healing surgical scars as traditional silicone gel.
Another study from 2008 showed using this ingredient helped reduce surgical scar texture, redness, and overall appearance in 60 patients.
According to a manufacturer, this ingredient can help with the following:
Another manufacturer from Spain claims onion extract can inhibit the release of allergy hormones and prostaglandin, or lipids found near tissue damage and infection spots.
This ingredient is water-soluble.

This ingredient has two peak UV absorption peaks ( 310 and 340 nm) and is able to absorb both UV-A and UV-B rays. This ingredient works by preventing UV rays from reaching and damaging your skin.
On top of that - it is highly photostable and helps prevent the photodegration of other sunscreen ingredients such as avobenzone.
Tinosorb S is allowed in the EU, Australia, and Asia. It is close to being approved by the FDA and we'll hopefully get this ingredient in the U.S. by late 2025.
Fun fact: Tinosorb S is the most effective UV absorber at maximum concentration (measured by SPF) permitted in the EU.
This ingredient is oil-soluble, so your oil-cleansers will take this right off at night.

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

It helps soften and soothe the skin by creating a thin film on top. This film helps trap moisture, keeping your skin hydrated.
Dibutyl Adipate is an emollient and solvent. It is created from butyl alcohol and adipic acid.
As a solvent, Dibutyl Adipate helps mix and disperse ingredients evenly.
Dibutyl Adipate is soluble in water and organic solvents. It does not absorb UV rays.

DHHB is well-liked for:
DHHB has been approved by the EU, Japan, Taiwan, and South America for use up to 10%. Unfortunately, it has not been approved for use in the US or Canada due to slow regulatory processes.
This ingredient is soluble in oils, fats, and lipids.
Learn more about Diethylamino Hydroxybenzoyl Hexyl BenzoateEthylhexyl Triazone is a modern chemical sunscreen that protects from UV-B radiation.
It is the most effective of existing UV-B filters, as it provides the highest level of photo-stable absorption. It protects from the entire UV-B range (280 to 320nm), with it's highest level of protection at 314nm.
Ethylhexyl Triazone is oil soluble, oderless and colorless, which mean it is able to be incorporated into a variety of different formulations.
It is not currently available within the United States due to slow changing FDA regulations. Outside of the US, it is used in formulations at concentrations up to 5%.

And the best part? It's gentle and well-tolerated by most skin types, including sensitive and reactive skin.
You might have heard of "niacin flush", or the reddening of skin that causes itchiness. Niacinamide has not been found to cause this.
In very rare cases, some individuals may not be able to tolerate niacinamide at all or experience an allergic reaction to it.
If you are experiencing flaking, irritation, and dryness with this ingredient, be sure to double check all your products as this ingredient can be found in all categories of skincare.
When incorporating niacinamide into your routine, look out for concentration amounts. Typically, 5% niacinamide provides benefits such as fading dark spots. However, if you have sensitive skin, it is better to begin with a smaller concentration.
When you apply niacinamide to your skin, your body converts it into nicotinamide adenine dinucleotide (NAD). NAD is an essential coenzyme that is already found in your cells as "fuel" and powers countless biological processes.
In your skin, NAD helps repair cell damage, produce new healthy cells, support collagen production, strengthen the skin barrier, and fight environmental stressors (like UV and pollution).
Our natural NAD levels start to decline with age, leading to slower skin repair, visible aging, and a weaker skin barrier. By providing your skin niacinamide, you're recharging your skin's NAD levels. This leads to stronger, healthier, and younger looking skin.
Another name for vitamin B3 is nicotinamide. This vitamin is water-soluble and our bodies don't store it. We obtain Vitamin B3 from either food or skincare. Meat, fish, wheat, yeast, and leafy greens contain vitamin B3.
The type of niacinamide used in skincare is synthetically created.

Due to regulation loopholes, this ingredient is not required to be labeled as an active chemical filter like other UV ingredients. This is why you'll likely find this ingredient in mineral sunscreens from the US.
Polysilicone-15 is not water-soluble.
Learn more about Polysilicone-15Silica is a mineral naturally found in our skin. It helps to thicken and smooth the texture of a product. It also acts as an agent for other ingredients by increasing the absorption of other ingredients into the skin.
Silica is often used for absorption and can help reduce shine when products are applied. Silica occurs in naturally in materials like clay and sandstone, and it can also be produced synthetically.
Silica is present naturally within the skin during collagen production and when reducing inflammation.

So why is it so popular? Water most often acts as a solvent - this means that it helps dissolve other ingredients into the formulation.
