Unique Rosemary Extract that Protects Skin from Urban Stress

Defending against oxidative and pollution-induced stress

For decades, dermatologists have understood the impact of solar radiation on the skin’s pigment and elasticity, but more recent studies have sought a deeper understanding of airborne pollution and its pernicious effects on skin health and chronic skin disease. As the body’s largest organ and a vital roadblock against the outside world, the skin helps regulate body temperature, prevent dehydration and safeguard against pathogens. Unfortunately, our daily exposure to pollutants—indoors and out—can weaken the skin’s ability to perform these functions while accelerating visible skin aging.

While pollution exposure is thought to occur outdoors in urban and industrial areas, the U.S. Environmental Protection Agency says Americans spend around 90% of their time indoors. According to the EPA, pollutant concentrations can be 2-5× higher indoors than outdoors, on average. In recent years, this daily contaminant assault has produced increasing consumer demand for anti-pollution skin care and cosmetic solutions to battle inflammation, oxidative stress, skin dullness and premature wrinkles.

Use of Rosemary Extract for Skin Care

One of the top plant-based ingredients known for its anti-pollution properties is rosemary. Rosmarinus officinalis is a distinctively aromatic herb from the peppermint family that is native to the hills surrounding the Mediterranean Sea. Traditional rosemary extracts using solvents as the extraction medium list benefits emanating from key plant constituents like camphor, caffeic acid, Rosmarinic acid, α-Pinene and borneol, which are responsible for its anti-inflammatory, antifungal and antibacterial qualities.

However, when rosemary is extracted using Sensient Cosmetic Technologies’ Phytoclean™ sub-critical water extraction process, the primary phytochemicals in the extract are rosmarinic acid and isorhamnetin-3-O-hexoside, leaving out more non-polar constituents.  This selective extraction provides a unique botanical extract that has benefits not available to standard rosemary extracts produced using solvents.

Benefits of Natpure Xtra Vitality

An essential feature of Natpure® Xtra Vitality is its unique ability to strengthen the skin’s resilience and cell cohesion, creating a more effective barrier against pollution. Related benefits validated by in vivo studies include:

  • Significant reduction in the production of MDA (malondialdehyde): A common skin marker for oxidative stress during UV and dust exposure. 
  • Restoration of catalase enzyme activity: An enzyme that converts highly reactive H2O2 into water and oxygen, further protecting skin from oxidative stress. Validated by in vivo studies.
Responsibly Sourced Rosemary

Sensient proudly sources rosemary extract from fair-for-life farms in central Uganda, where our farming partners practice sustainable agriculture and biodynamic farming techniques. We understand that consumers want products that are as powerful and ethical as they are clean, and Natpure® Xtra Vitality has a unique biological performance optimized by our use of sub-critical water.
