ZAZA & CRUZ to create a unique natural skincare blend using by-products of the whisky distillation process to rejuvenate and moisturize the skin whilst also shielding against cellular damage and anti-aging.

Background

ZAZA & CRUZ is a natural skin care company that aims to provide high-quality natural ingredients at a reasonable price. Its mission is to make its customers feel confident in their skin.

Rebecca Hastings, a makeup artist, and beauty specialist founded the company in 2013. Her children inspired the company’s name. As a make-up artist, she became increasingly concerned about what was in the products applied to the skin of her clients and her children.  Consequently, she researched the most beneficial natural oils and botanicals in 2011 and created her unique natural blend of ingredients that rejuvenated and moisturized the skin while also shielding against cellular damage and anti-aging.

The Challenge

Kirsty of Interface met Rebecca at a HIE event in 2019, where they discussed the innovation potential of her business.  They chatted about the beneficial effects on aging of the skin that the sake yeast fermentation process was proven to have by a Japanese company SK 11 in the 1970’s. The resulting complex that was created is now used throughout the whole Japanese skincare range.  This led on to a conversation about the potential of whisky in skincare.

ZAZA & CRUZ were looking to use natural ingredients and processes to develop an active antioxidant/enzyme extract from whisky which would help with skin rejuvenation and could be used in their luxury skincare range.

Rebecca, founder of ZAZA & CRUZ was seeking to find out if the antioxidants and enzymes produced during the whisky distilling process could prove beneficial for skin rejuvenation in collagen and cell turnover, and if they could be extracted to become a natural ingredient in her skincare products.

The use of the findings will enable ZAZA & CRUZ to infuse a brand of whisky into their luxury skincare line. This in turn will benefit the partner of the whisky brand to tap into a wider cosmetics market.

The Solution

Robert Gordon University came forward to support Rebecca’s ideas, and Kirsty stayed on hand to support Rebecca with discussions. Rebecca felt that the expertise and enthusiasm from the team at RGU were the right fit for her and so moved forward with an Innovation Voucher

The project focussed on extraction, analysis and testing to discover and prove that the active and complex mix of antioxidants, enzymes and plant phenols released from whisky during the distillation and fermentation process could be extracted and provide a natural and safe solution for the skin which could then be used in the whole luxury line of skincare products for the consumer.

Firstly, the project looked at the antioxidant capacity of pot ale and effluent samples from whisky distillation using different assays as well as evaluating their toxicity at a cellular level. This was then applied into the formulation of the skincare products. Finally, an assessment of their antioxidant activity, that is, their protective effects on skin, was investigated.  It was found that placing the nutrients from whisky in skincare can help to boost the skin and help fight free radical damage from the environment.  In addition, polyphenols from whisky have the added benefit of helping to reduce inflammation, puffiness, and calms redness in the skin; making is a great ingredient to use in a moisturiser every day.

The findings from this collaboration will enable ZAZA & CRUZ to infuse a brand of whisky products into their luxury skincare line that can benefit consumers’ skin.

The Benefits

The benefits to ZAZA & CRUZ:

• Being able to work with a highly specialized and qualified team at RGU with great knowledge of the extraction process for antioxidants.
• A better understanding about the process of extraction and how to adopt a more scientific approach towards testing and incorporating ingredients into skincare products.
• Quality results that can be used to push the project forward and be innovative in the skincare industry.
