From a Goodread's review:

"This is a well written book that will help you understand how and why your skin care purchases matter.  Moreover, you will learn how to protect your skin.  Readers of any age will find information of value to their health.  During a recent visit to a Plastic Surgeon's office to ask a few questions...you guessed it, this book was on the physician's shelf."

Skin and Hair Care Technology Issues for 2024: 

Several product claims have gotten way ahead of the scientific support, resulting in indistinguishable competitive positions and consumer disappointment with performance. A deeper understanding of the technology can break through the noise and satisfy consumer expectations.  Here is what to watch:

Clean Beauty.  One-third of products make this claim, but consumers have no way to distinguish among them.  Animal ingredients were replaced by harvested botanicals, which were supplanted by cultivated botanicals.  The next phase, which is already upon us, is fermented ingredients.  They are sustainable, higher quality and therefore safer.

Microbiome.  The discussion of bacteria on the skin has gotten past the “icky” factor and now sweeping claims are made for taming the microbiome, unsupported by science.  Products crowd each other with such marketing but without performance consumer interest will lag.  Meanwhile, at the lab bench, remarkable new findings point the way to how products can optimize the skin and hair microbiome interaction with healthy results.  Watch for these very specific promises and technically feasible delivery. 

Aging v Wellness.  Aging skin and hair were easy marketing targets, but no more.  In skin, botox and fillers have been so successful that anti-aging performance of topicals is minimized by comparison.  Where they can stand out is in areas beyond injectables, such as inflammation and pigmentation.  An enormous unmet need remains sensitive skin.  New technology based on broader knowledge of the triggers of skin discoloration and discomfort will help drive new product sales.

China compliance.  For many years China regulatory compliance was a drag on innovation and sustainability since new technology was not on the approved list.  Now, without the reliability of growth in the Chinese market, global players will bring true innovation to products sold in most countries and China may be left behind.  Remarkable innovations are straining to be set loose.
