What Is Chlorella Minutissima Extract?

Chlorella minutissima extract is derived from a freshwater microalgae species. It is rich in amino acids, vitamins, minerals and polysaccharides that are extracted and incorporated into skincare formulations for their conditioning properties.

In cosmetics, this ingredient functions primarily as a skin conditioner, helping to support the skin's moisture content and overall texture. It is used across a range of product types, from serums and moisturisers to targeted treatments.

How It Works

Chlorella minutissima extract works primarily through its humectant and emollient properties. The polysaccharides and amino acids in the extract can form a protective film on the skin surface, helping to reduce transepidermal water loss and lock in moisture.

The antioxidant compounds within the extract, such as chlorophyll and carotenoids, may help neutralise free radicals generated by UV exposure and environmental pollution, potentially reducing oxidative stress at the skin surface.

Clinical Evidence & References

Research specifically on Chlorella minutissima extract in skincare is limited. Most evidence comes from broader studies on chlorella species and their antioxidant and moisturising properties. These suggest the ingredient can support skin hydration and provide some antioxidant benefit when applied topically.

Further clinical studies would be valuable to establish optimal concentrations, long-term efficacy, and specific benefits for particular skin conditions. The ingredient is generally recognised as safe in cosmetics, but robust human studies in skincare formulations remain sparse.

How to Use

Chlorella minutissima extract is typically used as one of many conditioning agents in a formulation rather than as a standalone active. It works well in hydrating serums, moisturisers and essences. There is no particular risk of overuse, so it can be incorporated into both morning and evening routines as part of your regular skincare regimen.

Safety & Precautions

Chlorella minutissima extract is generally well-tolerated and considered safe for topical use in cosmetics. No significant adverse effects have been reported at typical usage levels, though those with known sensitivities to algae-derived ingredients should proceed with caution.
