Anese Play it Cool

In comedogenic testing, Beeswax scored a 0-2, which is on the low end. Whether or not a product clogs your pores really comes down to the formula as a whole (not any single ingredient on its own) and your skin.

Cera Alba is the white, bleached form of this ingredient.

Just so you know, beeswax is not vegan since it is animal-derived. It cannot be removed with water, but can be taken off with an oil cleanser.

People with a known Propolis allergy also report to have reactions from beeswax.

Beeswax's wax esters are derived primarily from palmitic and oleic acid (C16 and C18:1). Both of these fall within the C11-C24 feeding window.

The Malassezia yeast can potentially cleave these esters and release usable fatty acids, so this ingredient may not be fungal acne safe. However, not everyone will react to this ingredient.

Unlike other plant oils, jojoba wax doesn't easily penetrate skin. It mostly works in the uppermost layers as an emollient. This just means it forms a light barrier on the skin to help retain moisture.

Formulations with jojoba esters up to 90% reduced transepidermal water loss (TEWL) and increased barrier recovery by 81% (outperforming bisabolol at 47%).

Besides barrier support, the science also suggests jojoba to have anti-inflammatory effects and potential applications for skin infections, aging, and wound healing.

Fun fact: Indigenous cultures have used jojoba as a moisturizer and to help treat burns for centuries.

Fungal acne: The Malassezia yeast is known to metabolize fatty acids in the C11-24 range and jojoba's dominant fatty acid components fall into this range. This ingredient may not be fungal acne safe.

They contain shikimate dehydrigenase, an enzyme shown to help reduce inflammation and soothe the skin.

The amino acids found in cucumbers help nourish our skin's natural acid mantle (it's an important part of our skin barrier). This slightly acidic film acts as a barrier to protect us from bacteria, viruses, and other contaminants.

Unless you have an allergy to cucumbers, this is generally a non-irritating ingredient.

Fun fact: Cucumis Sativus is native to South Asia and can now be found on every continent.

Here's what the research shows:

In-vitro shows it calms inflammation signals; the most skin-relevant study put a kelp extract on human skin cells and then hit them with inflammatory triggers. The kelp-treated cells produced less of the inflammatory messenger molecules that normally get released.

In a realistic 3D model of skin, the pre-treated tissue held onto its cell-to-cell "seals" better and leaked less water (basically the lab version of a strong vs. weak skin barrier).

Two honest notes: the seal effect only showed up in the 3D model and at higher doses the extract started harming the cells (so more might not be better)

Fucoidan is why kelp gets talked about; it's the sulfated sugar molecule that brands like to name-drop. When four fucoidans were compared, the one from Macrocystis pyrifera was the most active. Just know this was from immune research and not skincare research.

On real people, the numbers look good (with an asterisk). The strongest evidence is all on Macrocystis Pyrifera Ferment inside one company's finished serum and not the plain extract.

Using it twice daily for eight weeks raised skin moisture 16 percent and cut water loss through the skin by 11 percent. A stripping test that repeatedly tapes and peels the skin surface found treated skin held up 30 percent better.

The standout result: half the face was prepped for three weeks and then the whole face got a 70 percent glycolic peel. The prepped side had recovered 71 percent of its barrier versus 23 percent untreated two hours later. A separate review also reported less visible redness and improvement in visible aging measures.

Three asterisk: It's the ferment, not the extract. The kelp isn't necessarily doing all the work since it's the whole formula. And it was funded by The Estée Lauder Companies with several authors on staff.

There's no fixed concentration published for this ingredient but real-world use survey shows this ingredient can be used up to 36%. There's an extra wrinkle for leave-on products since these extracts are usually supplier pre-diluted in water, glycerin, or propanediol.So "5%" on the bottle might mean under 1% for actual kelp solids.

On allergies: kelp is naturally iodine-rich, so people with a known iodine or seafood ingredient sensitivity should patch test.

You'll see algae listed as a 5/5 on a lot of pore-clogging charts and that number doesn't come from anywhere; it's not in the original rabbit-ear studies that most comedogenic ratings trace back to.

The reasoning behind the reputation is that seaweed is high in iodine and iodine can trigger acne-like breakouts when eaten. This traces back to a 1976 letter in Archives of Dermatology describing two women whose breakouts cleared after they stopped taking high-dose kelp supplements orally.

And the reaction of these two women wasn't clogged pores at all: it was an iodine-triggered pustular rash. Later research found normal dietary iodine doesn't meaningfully affect acne either and nobody has shown topical algae delivers enough iodine to matter.

What we do have is dozens of brown and red algae ingredients found to be non-irritating and non-sensitizing, and a handful of studies that found algae compounds may actually help acne.

However, plenty of people do report breaking out from algae-containing products. Skin is individual and it's worth avoiding if yours has reacted to algae before.

Citrus peel is also a rich source of flavonoids. Flavonoids are natural antioxidants and help protect your skin against damage. Flavonoids are a group of compounds naturally found in vegetables and fruits.

The term '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.

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.
