Ilso Moringa Purifying Pore Pad Versus Ilso Super Melting Sebum Softener

Industry-reported use ranges from 8% in rinse-off products and 2% in leave-on formulations.

Your skin makes glycerin on its own (mostly from sebaceous oil breakdown) and shuttles it to your outermost layer of skin, or your epidermis, via aquaporin-3.

Aquaporin-3 is a transporter that is essential for normal skin hydration, elasticity, and repair. Interestingly, mice lacking in AQP3 have dry and less elastic skin that can be fully corrected with glycerin.

This ingredient is non-irritating, plays well with almost every ingredient, and works across all skin types. Typical use is anywhere between 3-10% but can go up to 79% in some leave-on products.

Just know very high concentrations (>40%) can feel tacky in low humidity.

Glycerin is the name for this ingredient in American English. British English uses Glycerol/Glycerine.

The isoflavones are the workhorses behind the common claims; lab and animal studies show they mop up free radicals, help protect skin cells from UVB damage, and nudge fibroblasts to make more collagen while slowing the enzymes that break collagen down.

One controlled clinical study using an isoflavone cream reported softer wrinkles and better skin texture over time. A topical fermented soy extract also improved hydration and elasticity in an animal aging model.

The big caveat is that most of this evidence comes from soy isoflavones and related fermented soy extracts rather than this exact INCI. Some of the strongest data also comes from oral studies.

So it's best to think of this ingredient as a gentle, antioxidant-leaning conditioning agent rather than a proven wrinkle eraser.

At this time, there's no published concentration levels for this specific ferment but it usually shows up at modest levels in real products (~1% or less).

One last thing for people with soy allergies: it's always worth patch testing this ingredient despite the lowered allergy risk.

D-panthenol is also known as dexpanthenol. Most cosmetics use dexpanthenol or a mixture of D and L-panthenol.

Panthenol is famous due to its ability to go deeper into the skin's layers. Using this ingredient has numerous pros (and no cons):

Like hyaluronic acid, panthenol is a humectant. Humectants are able to bind and hold large amounts of water to keep skin hydrated.

This ingredient works well for wound healing. It works by increasing tissue in the wound and helps close open wounds.

Once oxidized, panthenol converts to pantothenic acid. Panthothenic acid is found in all living cells.

This ingredient is also referred to as pro-vitamin B5.

Fun fact: Purslane is a succulent with an extensive habitat. It is used in traditional Korean medicine to treat irritated skin.

Nowadays, purslane is becoming a superfood due to its highly nutritious content.

Your skin can't convert salicin to salicylic acid because it needs specific enzymes that aren't present on the skin's surface. It won't behave like true salicylic acid, especially at the concentrations used in cosmetics.

However, this ingredient has its own perks. It contains flavonoids, polyphenols, and tannins that give it proven antioxidant and soothing properties.

An 8-week clinical study found a cream with 2% of this extract improved skin microcirculation, elasticity, and dark circles. This is most likely due to its role in increasing hyaluronic acid synthesis in fibroblasts and improved vascular integrity.

Another study found a topical serum with 0.5% salicin showed improvements in visible signs of aging, hyperpigmentation, and texture.

Just be careful if you have a known aspirin/salicylate allergy and be sure to consult with a medical professional about using this ingredient if you do.

Fun fact: Willow Bark extract has been used for thousands of years and ancient civilizations used white willow to help treat pain and fevers.

In Chinese traditional folk medicine, Scutellaria Baicalensis Root Extract is used to help treat lung issues and hypertension.

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!
