What's inside

Ingredients Explained

Water

Skin Conditioning, Solvent

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!

Laminaria Digitata Extract

Skin Protecting

Laminaria Digitata Extract comes from the big brown seaweed (or kelp) that grows in the North Atlantic. In skincare, it's mostly used as a skin protectant and conditioning agent.

The most interesting stuff inside is mostly just sugars and minerals: fucoidan (a sulfated polysaccharide), laminarin (a beta-glucan), alginates, and phlorotannins (seaweed polyphenols).

Any antioxidant and soothing claims mostly come from those polysaccharides; crude laminarin and fucoidan from Laminaria digitata do show antioxidant and anti-inflammatory activity in lab assays.

Just know that the lab assays are test-tube work on isolated compounds and not clinical trials on the finished extract.

Realistically, this ingredient is a nice-feeling and hydrating skin conditioner (not really an active).

Safety-wise, it's one of the better documented seaweeds and safe to be used in cosmetics according to the CIR Expert Panel.

Industry surveys find that usage concentrations run can be found up to 5% in bubble baths and leave-on usage is more likely 0.1-3%.

The risk of allergy is also quite low as human repeat insult patch tests (under 5% and blends containing 8-12%) came back non-irritating and non-sensitizing. Rabbit studies came back negative too, though one trade mixture at 1.5-2.5% in water + propylene glycol did cause moderate irritation at 30 minutes.

Reported seaweed allergies in the literature are almost all occupational (people handling wet kelp) or from a totally unrelated blue/green alga.

You'll see seaweed 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.

The 0-5 scale comes from applying ingredients to the inside of an albino rabbit's ear. Rabbit follicles are far more reactive than human ones so it over-predicts. Even petrolatum was reassigned as non-comedogenic by the original scientist, Kligman.

Here are three more problems of comedogenic ratings:

Carbomer

Emulsion Stabilising, Gel Forming

Carbomer is a synthetic thickening and gelling agent. It's basically the ingredient that gives a lot of serums, gels, creams, and sunscreens their smooth, non-sticky texture.

Although legally permitted at very high levels, carbomers are normally used at concentrations below 1%.

It also needs to be neutralized to actually thicken, and because it is a large molecule, it doesn't really penetrate the skin barrier.

Allergy-wise, the risk is very low. Clinical studies show carbomers have low potential for skin irritation/sensitization even at concentrations up to 100%.

A 2024 UK study patch-tested 1,302 patients and found true allergy to the parent group of carbomer to be rare with no confirmed relevant reactions.

Sodium PCA

Humectant, Skin Conditioning

Sodium PCA (the salt of PCA) is one of the most well-established humectants in skincare.

Why is it so special? Your skin already makes it naturally; it's a natural component of your skin's Natural Moisturizing Factor (NMF), or the mix of water-binding compounds inside your skin cells that keeps things soft and hydrated.

As a cosmetic ingredient, it grabs water and holds it in the upper layers of skin to smooth roughness and ease dehydration.

There's some clinical support for the NMF approach with a study showing that a cream built to mimic the skin's NMF significantly boosted hydration.

Safety-wise, this ingredient non-irritating, non-comedogenic, and non-phototoxic in testing, with minimal skin absorption.

It also works really well with other hydrators like glycerin or hyaluronic acid, and typical usage is somewhere between 0.2-4%.

Aminopropanol

Caprylhydroxamic Acid

Caprylhydroxamic Acid is a chelating agent that helps cosmetics stay fresh, stable, and consistent over time.

Chelating agents help prevent metal ions from binding to other ingredients. This helps prevent unwanted reactions and effects from using the product. It also helps prevent the growth of unwanted microbes in products that contain water.

Caprylhydroxamic Acid is often used with natural antimicrobial products as an alternative to preservatives.
