Ingredient review
Hydrolyzed Maca Root Extract
INCI: Hydrolyzed Lepidium Meyenii Root Extract
A gentle antioxidant extract from maca root that may help protect skin from environmental stress, though research is still early.
In plain English
This is a processed version of maca root, a plant from Peru. The hydrolysis breaks down the root's proteins into smaller pieces, making it easier for the skin to absorb. It's thought to help defend the skin from damage caused by pollution and UV rays, but the evidence is not as strong as for more studied antioxidants like vitamin C.

What it is
Hydrolyzed Lepidium Meyenii Root Extract is a water-soluble extract from maca root that has been broken down (hydrolyzed) to reduce particle size and improve skin penetration.
How it works
It works primarily as an antioxidant, meaning it can neutralize free radicals—unstable molecules that can damage skin cells and accelerate aging. It may also help support the skin's natural barrier function by providing amino acids and other nutrients.
Pros
Gentle antioxidant
Provides antioxidant protection without the irritation that some stronger antioxidants (like pure vitamin C) can cause, making it suitable for sensitive skin.
Skin conditioning
The hydrolyzed proteins can help soften and smooth the skin's surface, improving texture over time.
Cons and cautions
Limited research
Most evidence comes from lab studies or traditional use, not large human clinical trials, so its effectiveness is less certain than more established ingredients.
Variable potency
As a natural extract, its active compound levels can vary between batches, leading to inconsistent results in different products.
Best for
- People looking for a gentle antioxidant
- Those with sensitive skin who react to stronger antioxidants
Use caution if
- Anyone with a known allergy to maca or cruciferous vegetables
Usage tips
Safety summary
Generally recognized as safe for topical use in cosmetics. No significant irritation or sensitization has been reported in available safety assessments.
Research notes
Research is preliminary. In vitro studies suggest antioxidant activity, but well-controlled human trials are lacking. More evidence is needed to confirm anti-aging or barrier-support claims.
Common label clues
- Typical concentration
- 0.1% to 2% in leave-on products
- Regulatory status
- Approved as a cosmetic ingredient in the EU and US; no specific restrictions beyond general cosmetic safety requirements.

- Environmental note
- Maca is cultivated in the high Andes of Peru; sustainable farming practices are important to protect local ecosystems.
Good to know
- Maca root is traditionally used in Peru as a food and for energy, but its skin benefits are a newer area of cosmetic science.
- Hydrolysis makes the extract more water-soluble and easier to formulate into serums and gels.
