What is biohacking? The truth behind the trend
I have been hearing the term biohacking again and again of late. But what is biohacking and should we get getting on the bandwagon? As you might expect, I have done some research…
Biohacking is one of the biggest wellness movements of the past several years. It sits somewhere between health optimisation, longevity culture and modern self experimentation. Depending on who is talking about it, biohacking can mean anything from improving sleep quality to injecting unregulated peptides in pursuit of eternal youth.
Women aged 35 to 55 are increasingly being exposed to biohacking language through skincare, supplements, podcasts and social media. Terms like NAD⁺, mitochondrial health, peptide therapy and cellular optimisation are now entering mainstream beauty conversations. Some of this science is genuinely exciting - some of this science I have already wrapped into my own SkinGoal skincare products. Some of it is marketing theatre dressed up as science - and can be dangerous.
The important thing is understanding the difference.
So what actually is biohacking?
At its simplest, biohacking means attempting to influence or optimise the body’s biological processes. Some biohacking practices are sensible and evidence informed. Others are extreme, expensive and poorly regulated - and, as I already said, can be dangerous. That is exactly why the conversation needs grounding in biological reality.
The spectrum is enormous. On one end, biohacking might look like:
• Improving sleep consistency
• Strength training to preserve muscle and bone density
• Supporting skin with antioxidants and Vitamin A
• Managing blood sugar balance
• Protecting skin from UV damage
• Supporting mitochondrial health through nutrition and lifestyle
These ones I am firmly behind.
On the other end, it can involve:
• Experimental peptide injections
• NAD⁺ intravenous drips
• DIY hormone manipulation
• Extreme fasting protocols
• Unregulated stem cell treatments
• Obsessive biometric tracking
These get a big nope from me!
Why biohacking appeals to us midlife women
Let’s face it, women in midlife are often navigating enormous biological change - and that can affect every single part of our lives – and our bodies.
Hormonal fluctuations affect collagen production, inflammation levels, skin recovery, sleep quality and energy metabolism. Skin can suddenly feel thinner, more reactive or more fatigued. Indeed, our skin definitely IS feel thinner, more reactive or more fatigued. It feels as though their body has changed the rules without warning.
Biohacking culture promises control. It sells the idea that ageing can be slowed or outsmarted if you simply find the right protocol, supplement or technology.
That is an incredibly powerful message - the problem is that fear-based decision-making is not the most sensible way to approach any of these challenges.
The rise of longevity beauty
One of the fastest growing areas within biohacking is longevity beauty. This is where skincare moves beyond surface appearance and begins focusing on cellular energy, inflammation, DNA repair and mitochondrial function.
You will increasingly hear terms like:
• NAD⁺
• NMN
• Peptides
• Senescent cells
• Cellular energy
• Epigenetics
• Regenerative aesthetics
Indeed, I have already written about a number of these topics, most recently NAD+ and NMN, which I have incorporated into my fabulous nighttime serum, Power DNA.
Some of these areas hold real scientific promise. Cellular ageing is a legitimate area of research. Skin absolutely changes at a mitochondrial level with age. But social media often removes, focussed as it is on the selling and not the education.
Women are being sold the fantasy of age reversal rather than the reality of skin function. Healthy skin is not created through panic, obsession or endless interventions. Healthy skin is built through consistency, protection, intelligent renewal and reduced inflammatory burden over time.
Where SkinGoal stands on biohacking
At SkinGoal, we are interested in biology, not gimmicks.
There is genuine value in understanding how skin cells produce energy, repair DNA and respond to stress. This is where advanced technologies like Power DNA and NAD⁺ supportive skincare become exciting. Supporting cellular energy can help improve resilience, recovery and overall skin vitality in midlife skin.
But biology must always come before hype. No peptide, injectable or supplement can override chronic inflammation, UV damage, poor barrier function or exhausted skin behaviour.
Skin health still depends on fundamentals:
Cleanse with intention
Feed the cells
Cue renewal
Protect every day
That remains true no matter how advanced the wellness industry becomes.
The dangers of extreme biohacking culture
One of the most concerning aspects of modern biohacking is the growing belief that ageing itself is failure. Honestly, don’t we women have enough to contend with without being made to feel like we’re getting it wrong – again?!
Women are being encouraged to monitor every fluctuation in energy, appearance and weight as though the body is a machine constantly requiring correction. This creates a very disconnected relationship with health.
Ageing is not weakness! Ageing is natural. Skin changes are not personal failure. The goal should not be trying to become biologically perfect. The goal should be healthier function, stronger resilience and better quality skin over time.
There is a profound difference between supporting biology and waging war against it.
So, is biohacking good or bad?
The answer is neither.
Some biohacking practices are simply intelligent health habits with modern branding attached to them. Who hasn’t known that good sleep habits reduce stress? Who doesn’t know that staying fully hydrated supports skin health? Who hasn’t been aware for years that SPF is a daily necessity, not an occasional application?
Others are commercially driven fear narratives designed to exploit insecurity. The key is knowing what is helpful and what is not. Ask yourself:
Does this improve biological function or simply chase appearance?
Is this evidence informed or trend driven?
Does this create resilience or dependency?
We deserve truthful education, not wellness intimidation. The future of skincare and longevity should feel intelligent, calm and biologically grounded.
That is the difference between real skin health and modern, highly pressured, fear-inducing optimisation culture.
The term my mother used to use is ‘ageing gracefully.’ She meant just accepting all those visible signs of ageing. I use the term ‘ageing intelligently’. We can’t prevent ageing, the clock keeps turning whatever we do. What we can do is make sensible, informed decisions and feed our bodies and our skin the ingredients that support it and extend longevity.
What is biohacking and why is everyone talking about it? FAQs:
Q: What is biohacking?
A: Biohacking is the practice of trying to influence or optimise the body’s biological systems. It ranges from simple lifestyle habits like sleep improvement and nutrition to more extreme interventions such as experimental injections or unregulated therapies.
Q: Is biohacking scientifically proven?
A: Some elements are evidence based, such as sleep optimisation, strength training, UV protection and blood sugar balance. Others are still emerging or poorly regulated, particularly around advanced longevity treatments.
Q: What is longevity beauty?
A: Longevity beauty is a growing branch of biohacking focused on skin at a cellular level. It includes concepts such as mitochondrial function, inflammation, DNA repair and epigenetics.
Q: Does advanced skincare really reverse ageing?
A: No skincare or supplement can reverse ageing. Some ingredients may support cellular energy or improve skin resilience, but they cannot override factors like UV damage, chronic inflammation or barrier dysfunction. Healthy skin still depends on consistent, protective habits.
Q: Is biohacking good or bad?
A: It is neither. Some practices are simply modern versions of basic health habits. Others are driven by marketing rather than science. The key is recognising which is which.
