The Holistic View of Beauty

Introduction

Back in 2020, when I started my adventure as a cosmetic scientist and formulator working at a contract manufacturer, I was introduced to suppliers and brands that suggested ingestible ingredients as an effective treatment to improve the way our skin, hair and nails looked. We called it at the time the “inside-out” approach to beauty. Although I knew about the association of certain vitamins with skin and hair aspect and quality, the supplements were more complex, from collagen to carotenoids to different phytochemicals with issues related to release, stability, bioavailability, etc.. Mostly because the lack of sufficient clinical evidence and the challenge for suppliers operating in the cosmetic industry to support clinical trials addressing the inside-out approach, many of these ingredients went unnoticed in the bigger picture of beauty and made their way through the nutraceutical market with a certain success, focusing on general wellbeing or wellness. Back in the day, I believed that the predominant dogma of addressing skin care and hair care as a specific target using topical products, almost like skin and hair were disconnected from the rest of our body, slowed down the adoption of a more holistic approach, and the idea to address beauty through an inside-out intervention as well.

A Holistic World

The holistic view of our body has been explored and developed for thousands of years in TCM and Ayurvedic Practice and represents a philosophy of life. We are looking at interactions and equilibrium between our senses, our organs and our external world with its colors and smells, but also with its dangers (pollution and stress in all their form). The notion that we are completely connected as individuals and with the environment is not surprising either. We just lived the disconnect for too long. There is a willing to reconnect to ourselves, our communities and nature. Sounds familiar? This is very much in line with the principle of sustainability, but also with a holistic view of the world where individuals function better as communities. Connections are complex though and not necessarily linear. This is why it is risky to simplify; but in general, we can draw some essential concepts that I think are main takeaways when approaching the skin and hair as part of our body and subjected to its rules.

The Scientist View

First, embryology studies taught us that some organs derive from the same embryonic tissue. When we think about the brain, skin, hair connection we realize that all these organs are derived from the same ectoderm layer during embryogenesis. Although these organs eventually differentiate to assume morphology and function completely different from each other, they do share mechanisms and pathways that are similar and interconnected. Some years ago, this basic understanding allowed scientists to develop concepts around the so-called neurocosmetics or the brain-skin-hair- axis.1,2 These concepts are becoming more prevalent these days since they are helping us to understand how stress and our mind influence our body and our appearance. When stress, either internal (psychological) or external (environmental), hits us, it definitely has an impact on how our skin and hair looks. Although it is common sense, since we have experienced it in the past either ourselves or seeing on other individuals, science is helping now connecting the dots between stress, related neurotransmitters and a physiological change ultimately associated with a condition and/or an appearance (looking good or looking bad).

The Intimate Connection

Stress has been part of my life earlier on (Buddhism believes that since stress or trauma starts with birth and never really goes away, we spend our lifetime to figure out how to reduce it or alleviate it with a goal of trying reach a more balanced, happy state) and I am pretty sure that some of the specific pain I felt in some parts of my body when I was younger were created by my brain: also called a psychosomatic state. I am sure it may have happened to some of you. We generally believe that our mood can influence our organs holistically. There are publications suggesting how a positive or a negative predisposition can affect a condition, even a very serious condition, with the body releasing certain hormones. But what about the skin or the hair and how our mood or senses-related stimuli can affect our look? It was not until reading some articles published in the late 90s by Prof Paul Bigliardi, that I realized that even the skin can change physiologically based on the influence of neurotransmitters (including our very own and not just CBD…). The discovery by Paul of opiate receptors carried deep in the dermis by tiny neuro-fibers was groundbreaking.3 And the intimate connection between these receptors, the transmitters and skin thickness!4 More recently, the presence of smell receptors in the skin and hair triggering physiological changes.5-6 Can our senses change our skin appearance? Probably yes… And what about our hair look and growth? Some recent work is evidencing how the hair follicle and dermal papilla cells can be directed to arrest growth by corticosteroids related molecules,7,8 and how mediators like Cortisol and Cortisol spikes can determine the way our hair grows or sheds.9 We have clinical evidence that by supplementing our body with phytochemical-based supplements we can change the way our hair and skin look.10,11 There is a bigger picture, which as cosmetic scientists we need to consider when creating cosmetic products for skin and hair, and this is our inner self.

Conclusion

Our body is one and our beauty depends on how we treat our body. Nothing deeper than that. Recent scientific discoveries explain how our senses are contributing to our appearance. We investigate how different ingredients, either applied topically or ingested, can help us maintain a healthy body and healthy look. The future is holistic, and science is now on our side!
