Let's Talk Skin! Part 3 — Advances in Antioxidant Technology for Skin Care

The third in a series of expert seminars in skin science called TRI Talking Skin will take place on Tuesday 23rd November with a talk from Dr Roger McMullen on the ‘Advances in Antioxidant Technology for Skin Care’.

In the last two decades the role of antioxidants in skin care has radically changed. In the early 2000s, it was typical to find finished formulas on the shelf that contained butylated hydroxy-toluene (BHT) or butylated hydroxyanisole (BHA), which were mostly added to enhance the shelf-life of the product. As time went on, formulas containing vitamin C and vitamin E (alpha-tocopherol) became more common since many studies carried out during that period demonstrated the invaluable benefits provided to the skin by these antioxidants.

As the personal care industry entered the end of the first decade in the new millennium, naturally derived ingredients started to become more and more common. Of course, most of these ingredients were based on botanical ingredients, which are chock-full of polyphenols and other ingredients with antioxidant properties. Antioxidants have also become key components of sunscreen formulas, as research demonstrated unique benefits from the addition of antioxidants in addition to any UV absorption properties.

A great deal of research has also gone into delivery systems for antioxidants, which provide targeted delivery and stability for antioxidants. Nowadays, one can find antioxidants in just about every type of skin care product in the marketplace. In this presentation, we will review some of the latest advances in antioxidant technology in the skin care arena.

Dr Roger McMullen is an Adjunct Fellow at TRI Princeton. He has over 20 years of experience in the personal care industry with specialties in optics, imaging, and spectroscopy of hair and skin. Currently, Roger is Principal Scientist in the Material Science department at Ashland Specialty Ingredients.
