Hydrolyzed Tiger Prawn Extract

INCI: Hydrolyzed Tiger Prawn Extract

A novel marine protein extract that may help hydrate and temporarily firm skin, but lacks robust human studies and is unsuitable for those with shellfish allergies.

In plain English

This ingredient is made from tiger prawns that have been broken down into tiny protein pieces (peptides). In skincare, it can help attract moisture to the skin and may give a temporary tightening or firming feel, similar to other hydrolyzed proteins. Think of it like a light, watery protein drink for your skin—it hydrates and plumps, but the effects are short-lived and not proven to change skin structure long-term.

Quick decision guide

Useful, but context matters

Hydrolyzed Tiger Prawn Extract is generally a lower-concern ingredient when the full formula suits your skin.

Plain-English read

Treat this as a practical screening step before you compare products that contain this ingredient.

  1. Step 1Start with the score, then check the irritation and clogging risk before judging Hydrolyzed Tiger Prawn Extract.
  2. Step 2Use the "Best for" and "Use caution if" sections to match the ingredient to your skin, not just to a marketing claim.
  3. Step 3If a product stings, breaks you out, or worsens irritation, judge the finished formula and stop using it even if the ingredient scores well.

Score terms in plain English

Irritation risk

low

Less likely to sting, burn, or bother most users, though sensitive skin can still react.

Clogging risk

low

Less likely to feel heavy or contribute to clogged pores for most skin types.

Evidence level

emerging

The ingredient may be promising, but claims should be treated more cautiously.

What it is

A hydrolyzed (enzymatically broken down) protein extract from the tiger prawn (Penaeus monodon), consisting of amino acids and small peptides.

How it works

When applied to skin, the small peptides form a thin film that can hold water, providing immediate hydration and a slight tightening effect. They may also temporarily bind to the skin's surface, reducing water loss and making skin feel smoother.

Pros

Immediate hydration boost

The hydrolyzed proteins attract water to the skin's surface, giving a quick plumping effect that can make skin look more supple and reduce the appearance of fine lines temporarily.

Novel ingredient for unique formulations

As a marine-derived peptide source, it offers a point of difference in products and may appeal to consumers interested in ocean-sourced ingredients.

Cons and cautions

Allergen risk for shellfish-sensitive individuals

Because it is derived from tiger prawns, anyone with a shellfish allergy could experience an allergic reaction, including redness, itching, or swelling.

Limited evidence for long-term benefits

Most claims about firming and anti-aging are based on the general properties of hydrolyzed proteins, not on specific clinical studies for this exact ingredient. Effects are temporary and not proven to change skin structure.

Best for

  • People looking for a temporary plumping or firming effect
  • Those who enjoy novel marine-based ingredients in their routine

Use caution if

  • Anyone with a known shellfish or crustacean allergy
  • Vegans and vegetarians

Usage tips

Apply after cleansing and before heavier creams to allow the peptides to absorb.
Store products containing this ingredient in a cool, dark place to maintain protein stability.
Patch test on a small area of skin before first full use, especially if you have sensitive skin or unknown shellfish allergy status.

Safety summary

Hydrolyzed Tiger Prawn Extract is considered safe for topical use in cosmetics at typical concentrations. The primary safety concern is the potential for allergic reactions in individuals with shellfish allergies. Otherwise, it is non-irritating and non-comedogenic for most skin types.

Research notes

There are no published peer-reviewed clinical studies specifically on Hydrolyzed Tiger Prawn Extract for cosmetic use. Its benefits are inferred from general research on hydrolyzed proteins and marine peptides, which show temporary hydration and film-forming properties. More research is needed to confirm efficacy and safety.

Common label clues

Typical concentration
0.1% to 2% in leave-on products
Regulatory status
Generally recognized as safe for cosmetic use in the US and EU when manufactured according to good practices. Not specifically regulated as a drug ingredient.
Common uses
Anti-aging serums, Firming creams, Hydrating masks
Environmental note
Tiger prawn farming can have environmental impacts including habitat destruction and water pollution. Look for sustainably sourced or certified ingredients if this is a concern.

Good to know

  • Hydrolyzed Tiger Prawn Extract is often used in conjunction with other humectants like glycerin or hyaluronic acid for enhanced hydration.
  • The hydrolysis process breaks down large proteins into smaller peptides, which are more easily absorbed by the skin.
