Ingredients Explained
Hyaluronic acid (HA) is a glycosaminoglycan (basically a long sugar chain) that your skin already makes on its own. In your skin, HA lives in the extracellular matrix and acts as the body's moisture reservoir.
Topically, HA is a humectant that binds water and helps skin look more plump, smooth, and hydrated.
The only catch is that HA isn't a single thing; it actually comes in a wide range of molecular weights (~50 - 2,000+ kDA) and size matters.
Some clinical evidence links low molecular weight versions to improved wrinkle depth, elasticity, anti-inflammatory effects, and barrier repair.
This is why the best HA serums blend the two sizes together so you get the best of both worlds.
The majority of cosmetic HA is produced by bacterial fermentation, typically using Streptococcus or Bacillus strains. Typical use levels in skincare sit around 0.1-2%.
A clinical study using a 0.2% low-molecular weight HA gel showed improvement in facial seborrheic dermatitis with excellent tolerance.
These are some other common types of Hyaluronic Acid:

This amino acid helps with:
- Maintaining DNA stability and cell reproduction
- Enhances cellular immunity
- Skin brightening
- Anti-aging
- Skin soothing
Hydrolyzed Soy Protein is a vegan protein made to mimic hydrolyzed collagen. It is created from soy, or glycine soja.
This ingredient is a humectant, meaning it helps hydrate the skin by binding to water. According to a manufacturer, it is also a great hair conditioner.

This ingredient contains both lipids and antioxidants. The lipids nourish the skin's barrier. Antioxidants help fight free-radicals. Free-radicals are molecules that may damage your skin cells.
This ingredient is good for soothing sensitive skin.
Many different types of algae have different benefits.

In lab and skin-model studies, this ingredient helps regulate how much pigment (melanin) the skin makes. It works by interfering with signals that tell pigment cells to âturn upâ melanin production instead of bleaching or stripping pigment thatâs already there.
It should be noted that most studies look at finished skincare formulas and not the ingredient on its own.
Products containing undecylenoyl phenylalanine have been shown to help improve the appearance of dark spots, discoloration, and uneven skin tone with regular use, especially when used consistently over several weeks.

In L'Oreal's published chemistry work, this ingredient was identified as a strong activator of sulfated glycosaminoglycan (GAG) biosynthesis.
This ingredient helped skin make more of its own natural âwater-holdingâ molecules (called GAGs) in lab studies and skin models, which are important for keeping skin plump and hydrated. It also supported proteins that help anchor and support the skinâs layers.
Most human studies look at full skincare formulas rather than the ingredient on its own.
In one 12-week study, a facial serum containing Pro-Xylane was linked to improvements in skin hydration, firmness, and the appearance of sun-damaged skin.
In a more recent study, a product with hydroxypropyl tetrahydropyrantriol plus niacinamide was used after laser treatments and showed visible improvements in fine lines, wrinkles, and overall skin appearance within about 8 weeks, along with signs that the skin was calming and repairing itself.

This ingredient is an osmolyte; Osmolytes help organisms survive osmotic shock (it protects them from extreme conditions). It does this by influencing the properties of biological fluids within cells.
When applied to the skin, ectoin helps bind water molecules to protect our skin. The water forms a sort of armor for the parts of our skin cells, enzymes, proteins, and more.
Besides this, ectoin has many uses in skincare:
A study from 2004 found ectoin to counteract the damage from UV-A exposure at different cell levels. It has also been shown to protect skin against both UV-A, UV-B rays, infrared light, and visible light.
Studies show ectoin to have dual-action pollution protection: first, it protects our skin from further pollution damage. Second, it helps repair damage from pollution.
In fact, ectoin has been shown to help with:
Fun fact: In the EU, ectoin is used in inhalation medication as an anti-pollution ingredient.
Ectoin is a highly stable ingredient. It has a wide pH range of 1-9. Light, oxygen, and temperature do not affect this ingredient.
The chemical name for this ingredient is Tetrahydromethylpyrimidine Carboxylic Acid.
