Beauty, sleep, and circadian rhythm with ByNACHT founder Jessica Hoyer

It was only a matter of time – and perhaps the right person, to bring beauty into the world of sleep. Inspired by her own experience with poor-quality sleep, ByNACHT founder, Jessica Hoyer, explores the connection between beauty, sleep, and circadian rhythm.

As experts in handcrafting the world’s finest beds, we are committed to discovering the ingredients that make up a restorative night’s rest. Throughout this journey, we have met some of the most esteemed individuals within the wellness space. Bringing together their knowledge, science and curiosity, these experts challenge the common perception of sleep and aim to provide modern-day solutions that deliver a lifetime of quality sleep.

Driven by her own experience with lack of sleep, Jessica Hoyer embarked on understanding the connection between beauty, sleep, and circadian rhythm. Combining cutting-edge technology with insight from world-leading sleep experts, she created a brand that makes our sleeping routines all that more luxurious.

With a curated range of creams, serums, and balms, ByNACHT (German for ‘By night’), provides key ingredients to a wholesome sleeping routine. Today, we sit down with Jessica Hoyer, who talks us through what inspired her journey and how her findings influence her approach to beauty sleep.

I wanted a concept and products that were wholesome, yet cutting-edge in ingredients and something that didn’t fall short in all aspects of the lines I used to buy.

Jessica Hoyer, founder of ByNACHT

Savoir: Is ByNACHT inspired by your own experience with lack of sleep? 

Jessica Hoyer: Yes, ByNACHT was literally born out of my own sleepless nights. Before I started the brand, I had my own advertising agency and was working for big international clients and frequently flying around the world for work. I was constantly jet-lagged, exhausted, and looked – and felt dull. My mother (a certified aromatherapist) mixed me the ‘sleeping balm’, which is still a bestseller and the original recipe as of today, and I finally had a good night’s sleep.  

Now, I was looking to find a skincare that helped with me looking dull. I wanted a concept and products that were wholesome, yet cutting-edge in ingredients and something that didn’t fall short in all aspects of the lines I used to buy. And there wasn’t a cure for it in the current skincare market. I didn’t find anything that was closing the gap between the scientific findings around sleep being a catalyst for great skin. When I started looking into studies I was immediately fascinated and knew I had found something very special. 


What’s driven you to explore the connection between circadian rhythm, sleep, and beauty? 

I have never intended to be a part of the beauty industry but created my brand out of my own passion after reading all the studies and mostly my need to find something that is science-based and holistic in the approach to combine sleep and skin. Because these scientific studies and findings all state that sleep quality impacts skin function and ageing. 

In terms of science, my biggest learning was that every single study and scientific research facts and findings say that skin renewal, wound healing, growth hormones, collagen production, fibroblast renewal and overall turn-cell over and really, basically everything else that is needed for amazing skin are ONLY happening at night.  

As for wound healing, it was mind-blowing to see what the right ingredients (at this time it was our ultra-repair serum) and a good night’s sleep can do for your skin. And those scientific facts were, and still are my biggest guidance when creating a new product.

How did your findings inform your approach to sleep and beauty? 

Skin never sleeps and that is probably the most interesting research finding ever. During the day, your skin is in a protective state, warding off elements such as sun damage or oxidation. While at night, your skin goes into renewal mode, regenerating new skin cells and cycling oxygen and nutrients. 

Our skin has its own circadian clock. Different skin processes occur at different times according to this internal schedule. Night time is prime time for repairing damage and rebuilding cells and tissues, and cell renewal is up to 8 times higher. Collagen production and Growth hormone (HGH) production are at a peak which in turn accelerates skin regeneration and the production of antioxidant enzymes.  

The bottom line is – support your skin at night with the right products and you will see a dramatic difference in your complexion by day.

What is your current bedtime routine and how do you maintain it when travelling? 

The time before going to bed is my ‘me-time’ and whether I have 10 or 30 minutes, I never skip cleansing my face and applying my skincare. I combine this with my relaxing playlist and write down every single to-do and thought in a little notebook, so my head is clear when I go to sleep.  

That is a game-changer really, so I feel well-prepared for the next day, and nothing gets lost when I have my morning coffee. This routine is something I really stick to, even when I am travelling because I found it to make such a difference the next morning in terms of how I look and feel. I also always bring our mini travel sizes with me when I’m away.


What’s the one luxury you can’t live without? 

I think a lot of people would expect me to say that my biggest luxury is sleep now, but for me, sleep is a necessity and vital for my well-being and overall health. I have learned so much about the importance of a good night’s sleep that I treat it as a priority. So, I will go with time with my son, as this is really the thing that means the most to me and no amount of money, work or opportunity could make me compromise or minimize that time.

For those unfamiliar with ByNACHT, is there one product you recommend starting with? 

Ohh, that’s a hard question as I love all of our products but I personally would say our Hypercharged Glass Skin Serum (a worldwide and award-winning bestseller we can’t keep in stock for long until sold out) that features an outstanding combination of eight different Hyaluronic acids and an unmatched combination of 13 different active botanical extracts.  

I would go as far as to say that if you have ever tried it, you will never go back to an ‘ordinary’ Hyaluronic Serum ever again. It is that good.  And then there is of course our original – the Sleeping Balm. It always works and thousands of raving customers can’t lie. You will sleep.


Do we need a different approach to skincare at night, than we do during the day? 

Yes, absolutely and in so many aspects – from the quality and components of ingredients to the sheer quantity we use. We need a lot more active ingredients at night in order to wake up with the best skin because of the skin being so active at night and some other factors like trans epidermal water loss. At night, the skin’s cells regenerate fastest due to the increased blood flow to the skin. If you use effective products, your skin can maximize its rejuvenation with serums and creams that help the skin renew itself. 

And for that, we need to have a night-time skincare line that is addressing skin issues before the regenerative process of sleep begins. So, ByNACHT products are designed very differently, you will see a difference within one night already. I strongly believe that high quality and efficacy will always come through.

And lastly, what is your advice for achieving a restorative night’s rest? 

My advice would be to invest in making your bedroom a sanctuary and a place where you really just rest. I never work or use my laptop in bed but make sure I keep a book and a pen nearby to write done any wandering thoughts before sleep.  

Investing in a high quality bed is also vital. We spend a lot of time in our beds and for me, that is the most important piece of furniture in my house.  

I also stick to the common rules, such as no phone before sleep, having a colder room temperature and if I am very exhausted, I take a warm bath before bed and do some breathwork and apply our sleeping balm- and I am off to the land of dreams.
