Ingredients Explained
These ingredients are found in both products.
Ingredients higher up in an ingredient list are typically present in a larger amount.
Aluminum Starch Octenylsuccinate is a synthetic powder used as an absorbent, thickener, and anti-caking agent.
As an absorbent, it is great at mattifying skin by soaking up the oil. This is why you'll find it in a range of products from makeup to moisturizers.
This ingredient is considered a modified starch. Starch can also be found naturally in plants.
One study from 1991 found that 5% of this ingredient enhanced titanium dioxide SPF by as much as 40%. The study found 1% titanium dioxide had a 5.6 SPF and adding 5% of aluminum starch octenylsuccinate boosted it to an SPF of 8.1
Although “aluminum” in an ingredient name can raise red flags for some consumers, the form and usage context matter significantly. For typical topical applications, there is no substantial evidence of health risks - such as cancer, neurotoxicity, or systemic “aluminum overload.”
Learn more about Aluminum Starch OctenylsuccinateYou might know this ingredient as Tinosorb S or Bemotrizinol. It is a UV filter that covers both UVA and UVB rays.
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.

It is a common ingredient in many products, especially those designed to hydrate skin. The primary benefits are retaining moisture, skin softening, and promoting a healthy skin barrier.
Though Caprylyl Glycol is an alcohol derived from fatty acids, it is not the kind that can dry out skin.
This ingredient is also used as a preservative to extend the life of products. It has slight antimicrobial properties.
Learn more about Caprylyl GlycolGlyceryl Stearate is a mix of glycerin and stearic acid.
It is used to stabilize the mixing of water and oil ingredients. By preventing these ingredients from separating, it can help elongate shelf life. It can also help thicken the product's texture.
As an emollient, it helps soften skin and supports barrier-replenishing ingredients.
In cosmetics, Glyceryl Stearate is often made from vegetable oils or synthetically produced.
This ingredient may not be fungal-acne safe
Fun fact: The human body also creates Glyceryl Stearate naturally.

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.

It's often used in formulations along with Caprylyl Glycol to preserve the shelf life of products.
This ingredient is more commonly known as Ensulizole, a chemical sunscreen ingredient.
Ensulizole mainly protects UV-B (290-340 nm) but offers a little UV-A (320-400 nm) protection. It is often paired with less photo-stable sunscreen ingredients due to its photo-stability.
Due to it being water-soluble, Ensulizole helps give sunscreens a light and non-oily texture.
Ensulizole is approved worldwide:

Potassium Cetyl Phosphate is an emulsifier and cleansing agent. Emulsifiers help stabilize a product. It does this by preventing certain ingredients from separating.
As a cleansing agent, Potassium Cetyl Phosphate helps gather oils, dirts, and pollutants from your skin. This makes it easier to rinse them away with water.
Learn more about Potassium Cetyl PhosphateSodium Hydroxide is also known as lye or caustic soda. It is used to adjust the pH of products; many ingredients require a specific pH to be effective.
In small amounts, sodium hydroxide is considered safe to use. However, large amounts may cause chemical burns due to its high alkaline.
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.
Learn more about Sodium HydroxideWater. 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.
So why is it so popular? Water most often acts as a solvent - this means that it helps dissolve other ingredients into the formulation.
You'll also recognize water as that liquid we all need to stay alive. If you see this, drink a glass of water. Stay hydrated!
