What-it-does: skin-identical ingredient, moisturizer/humectant

It’s naturally in our skin and behaves there like a sponge
It can bind up to 1000 times its own weight in water
It is a big molecule from repeated subunits (polymer) so different molecular weight versions exist (unfortunately there is no way to determine MW from INCI list only)
High-molecular-weight-HA (>500 kDa) is an excellent surface hydrator, skin protectant and can act as an osmotic pump helping water-soluble actives to penetrate deeper into the skin
Low-molecular-weight-HA (< 500 kDa) can hydrate the skin somewhat deeper though it is still a big molecule and works mainly in the epidermis (outer layer of the skin)
Low-molecular-weight-HA might also help the skin to repair itself by increasing its self-defense (~ 200kDa used in the study)
Ultra-low-molecular-weight-HA (<50kDa) is a controversial ingredient and might work as a pro-inflammatory signal molecule

Niacinamide - superstar

Also-called: vitamin B3, nicotinamide | What-it-does: cell-communicating ingredient, skin brightening, anti-acne, moisturizer/humectant

A multi-functional skincare superstar with several proven benefits for the skin
Great anti-aging, wrinkle smoothing ingredient used at 4-5% concentration
Fades brown spots alone or in combination with amino sugar, acetyl glucosamine
Increases ceramide synthesis that results in a stronger, healthier skin barrier and better skin hydration
Can help to improve several skin conditions including acne, rosacea, and atopic dermatitis

This ingredient name is not according to the INCI-standard. :( What, why?!

Glycerin - superstar

Also-called: Glycerol | What-it-does: skin-identical ingredient, moisturizer/humectant | Irritancy: 0 | Comedogenicity: 0

A natural moisturizer that’s also in our skin
A super common, safe, effective and cheap molecule used for more than 50 years
Not only a simple moisturizer but knows much more: keeps the skin lipids between our skin cells in a healthy (liquid crystal) state, protects against irritation, helps to restore barrier
Effective from as low as 3% with even more benefits for dry skin at higher concentrations up to 20-40%
High-glycerin moisturizers are awesome for treating severely dry skin

What-it-does: moisturizer/humectant, solvent | Irritancy: 0 | Comedogenicity: 0

It's a helper ingredient that improves the freeze-thaw stability of products
It's also a solvent, humectant and to some extent a penetration enhancer
It has a bad reputation among natural cosmetics advocates but cosmetic scientists and toxicology experts do not agree (read more in the geeky details section)
