Is Hyaluronic Acid vegan?

Depends

Short answer

Key takeaways

  • Verdict: Hyaluronic Acid is depends.
  • Commonly found in: Serums and moisturizers, Joint injections, Wound dressings.
  • Vegan alternatives: Brands explicitly stating 'vegan' or 'fermented HA' (The Ordinary, Inkey List, Krave).

What it is

A humectant naturally found in skin, joints and eyes.

Why depends

Historically extracted from rooster combs. Most modern skincare HA is from Streptococcus or Bacillus fermentation — vegan. Always check the brand.

What a “Depends” verdict means

A 'depends' verdict means the same ingredient name covers both plant and animal sources, and the label alone cannot tell you which one is in the tub. Certification, an allergen statement, or a direct answer from the manufacturer is the only reliable way to settle it.

Where you'll find it

  • Serums and moisturizers
  • Joint injections
  • Wound dressings

How to read the label

Hyaluronic Acid belongs to the cosmetic ingredients family. These are the terms worth scanning for on any ingredient list in this category:

  • Lanolin
  • Keratin
  • Collagen
  • Elastin
  • Guanine
  • Squalene
  • Carmine
  • Cera alba
  • Silk amino acids
  • Tallow
  1. Read the INCI list from the bottom for pigments and waxes, where animal entries cluster.
  2. Leaping Bunny answers testing; a vegan trademark answers ingredients. Look for both.
  3. 'Squalane (olive-derived)' or 'plant squalane' is an explicit vegan claim; unqualified squalane usually is too but is worth checking.
  4. Pearlescent products may use guanine from fish scales; mica is the mineral alternative.

Mistakes to avoid

Common cosmetic ingredients traps and what to do about them
Where it catches people outWhat to do
'Natural' skincareNatural often means lanolin, beeswax and honey — the opposite of vegan.
Shimmer and highlighterGuanine from fish scales gives the classic pearl effect.
Hair repair productsKeratin is typically from feathers, hooves or wool.

Cosmetic ingredients in context

Cosmetics use the INCI naming system, which is standardised worldwide but says nothing about whether an ingredient came from a plant or an animal. Lanolin, keratin, collagen, silk amino acids, squalene and guanine are all common animal-derived INCI entries.

Two separate questions matter in this category and are often conflated: whether the formula contains animal ingredients (vegan) and whether the product or its ingredients were tested on animals (cruelty-free). A product can be one without the other.

Squalene and squalane illustrate the ambiguity neatly — historically shark liver oil, now predominantly olive or sugarcane derived, with the same INCI name for both.

Does certification help? Leaping Bunny plus a vegan trademark together are the only reliable shortcut, because INCI names cannot express ingredient origin.

FAQ

Is The Ordinary's HA vegan?
Yes — Deciem (parent company) confirms fermentation-derived HA.
Is cruelty-free the same as vegan?
No. Cruelty-free means no animal testing; vegan means no animal ingredients. A cruelty-free lipstick can still contain carmine and beeswax.
Is lanolin cruelty-free?
It is a wool grease from shorn sheep, so no animal is killed, but it is an animal product and therefore not vegan.
