Ingredients Explained
These ingredients are found in both products.
Ingredients higher up in an ingredient list are typically present in a larger amount.
Ci 16035 is a synthetic dark-red dye. This dye is created from an acid called Allura red AC, an azo dye.
Azo dyes need to be purified thoroughly before use. This makes them more stable and longer lasting.
This dye is commonly used in foods, approved by both the FDA and EFSA.
Learn more about CI 16035CI 17200 is a synthetic, water-soluble, reddish-pink dye. It is used purely as a cosmetic colorant.
In the US, the FDA permits this ingredient in cosmetics but it is not approved for use around the eyes while the EU allows this to be used in all cosmetic products.
The FDA requires batch-to-batch certification for this ingredient that is held to a pretty rigorous standard. That means the CI 17200 in your cosmetics has been tested and approved before it ever reaches you.
Contact allergy to cosmetic-grade dyes used at low concentrations are uncommon but has been documented before.
This ingredient also goes by the name D&C RED NO. 33.
CI 17200 has a comedogenic rating of 1 and an irritancy rating of 2 on a scale of 0-5. This is based on peer-reviewed research from the man who invented the comedogenic scale.
A 1 on the comedogenic scale is about as low as it gets without being a flat zero, and makes sense for CI 17200.
It's a water-soluble dye used at very small concentrations (typically 0.001-0.1%), so it dissolves into the water phase of a formula rather than sitting on your skin the way an oil or wax would.
The irritancy rating of 2 reflects that, like most synthetic dyes, there's a small possibility of mild irritation ( particularly for people with existing dye sensitivities).
For the vast majority of people, it's a non-issue at typical use levels.
It's also worth keeping in mind that comedogenic and irritancy ratings are tested on individual ingredients, not finished formulas. The final product's formulation, concentration, and other ingredients all play a role in how something actually behaves on your skin.
Just so you know, the FDA ban on Red Dye No. 3 refers to CI 45430, not this ingredient. CI 45430 and CI 17200 are different chemical compounds with distinct safety and regulatory histories.
It's also worth noting that Red No. 3 (CI 45430) was already banned from cosmetics back in 1990, so the 2025 action just extended the ban to food and oral drugs. CI 17200 was never part of any of this.
Learn more about CI 17200CI 19140 is also known as Tartrazine. Tartrazine is a synthetic dye used in cosmetics, foods, and medicine to add a yellow color.
Tartrazine is created from petroleum and is water-soluble.
Some people may experience allergies from this dye, especially asthmatics and those with an aspirin intolerance.
Learn more about CI 19140Ci 42090 is a synthetic dye created from petroleum. It is used to give a bright blue color to cosmetics, medicine, and food.
Coumarins are a group of substances found naturally in plants. There are over 1300 types of coumarins identified. It has a natural vanilla scent.
Coumarin is an identified EU known allergy, meaning it may cause an allergic reaction when applied to the skin.
In many countries, coumarin is banned as a food additive. However, it can be found in soaps, tobacco products, and some alcohol drinks.
Plants use coumarins as a chemical defense. Some plants that have coumarins include lavender, tonka beans, and yellow clovers.

It's a simply sugar that reacts with the free amino acids in your outermost layer of skin to produce brown-colored compounds called melanoidins.
DHA does not penetrate living skin cells, does not interact with melanocytes, and does not affect actualy melanin production.
There's a "safety controversy" that largely stems from misinterpreted studies:
Once concern is that DHA can generate unstable molecules that can damage cells (free radicals) when exposed to sunlight. This only happens in the outermost layer of dead skin cells and wearing SPF on top takes care of it.
The DNA damage claim comes from lab studies that doused living skin cells in much higher concentrations of DHA than you'd ever find in a self-tanner. That's not really a meaningful comparison to putting self-tanning lotion on your skin.
Regulatory bodies around the world, including the EU's Scientific Committee on Consumer Safety (SCCS) and the U.S. FDA consider it safe for use in cosmetics when applied topically (maximum 10%, and most self-tanners contain between 3-5%).

Research shows how well this ingredient works depends on the active and formulation rather than the concentration alone. This means adding more Dimethyl Isosorbide does not guarantee better penetration of ingredients into the skin.
Parfum is a catch-all term for an ingredient or more that is used to give a scent to products.
Also called "fragrance", this ingredient can be a blend of hundreds of chemicals or plant oils. This means every product with "fragrance" or "parfum" in the ingredients list is a different mixture.
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.

It's often used in formulations along with Caprylyl Glycol to preserve the shelf life of products.
Sodium metabisulfite is also known as Sodium Pyrosulfite. It is a preservative, antioxidant, and disinfectant.
As a preservative, it helps stabilize cosmetic formulas without affecting their color or scent.
Water. 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. Remember to stay hydrated!
