Biotechnology in Skincare: A More Considered Approach to Ingredients

A Different Way of Thinking About Ingredients

For a long time, skincare conversations have focused on ingredients. What to use, how strong something is, and the results people hope to achieve.

But over the years, working closely with skin has shown me that something else matters just as much. Not only what we apply to the skin, but how ingredients are created, how reliably the skin experiences them, and how they behave over time.

Skin is constantly responding to its environment. It responds to the products applied to it, the frequency they are used, and the overall condition being created on the skin day after day.

When skin becomes unsettled, it is not always because one ingredient is wrong for the skin. Often, it is the accumulation of too many variables. Too many changes, too much inconsistency, and too much demand being placed on the skin at once.

Over time, this made me think more deeply about formulation itself. Not only which ingredients were being used, but how they were developed, how consistently they behaved, and how much unnecessary variability the skin was being exposed to.

What I was looking for was not more. It was fewer variables

Why biotechnology became important to me

This is where biotechnology became important to me. Not as a trend, and not simply as innovation, but as a controlled and considered way of developing ingredients that work in alignment with the skin and the microbiome that supports it.

Biotechnology is not a new ingredient category. It is a method, defined by how an ingredient is developed and understood.

What Is Biotechnology In Skincare?

Biotechnology refers to the use of controlled biological processes to create or refine ingredients used in skincare. One of the most recognised examples is fermentation, a process that has been used across food, medicine, and science for many years. ² 

Beyond fermentation, biotechnology in skincare also includes the use of controlled microbial cultures to produce specific activities and the development of biomimetic ingredients designed to mirror structures naturally found in the skin. What these approaches share is that each ingredient is created under defined conditions, with a clearer understanding of its structure and behaviour.

In skincare, biotechnology allows ingredients to be developed in a controlled and consistent way that goes beyond traditional extraction methods alone. This can help reduce variability between batches and create ingredients that behave predictably when applied to the skin. ³ 

Why skin responds well to consistency

For me, this is where biotechnology becomes interesting. Not because it sounds advanced, but because skin often responds well to consistency.

Traditional ingredient sourcing can naturally vary depending on climate, soil, growing conditions, and processing. ⁴  Biotechnology offers another way of working with ingredients, where the focus is not only on the ingredient itself but on creating it as consistently and precisely as possible.

This does not mean biotechnology replaces nature. In many cases, it works alongside it. The goal is not to make skincare more complicated, but to better understand how ingredients interact with the skin and the microbiome. ⁵ 

Biotechnology is often described as the future of skincare, but in many ways it is already part of the present. What matters most is not whether an ingredient is described as biotech, but whether it has been developed thoughtfully, used with restraint, and formulated in a way that supports the skin comfortably day after day.

Why This Matters for the Skin

Skin is not responding to one ingredient in isolation. It is responding to everything surrounding it. The products being used, how often they are applied, the condition of the skin barrier, and the overall environment being created on the skin over time all influence how the skin behaves. ¹ 

Over the years, I have worked with many people who felt confused by their skin. They were using well-formulated products, often with highly regarded ingredients, yet their skin still felt unpredictable. Sometimes reactive, sometimes uncomfortable, and often difficult to understand.

What became increasingly clear to me was that skin does not always respond well to constant change. New products, highly active routines, fluctuating ingredient quality, and too many competing steps can gradually create more variability in how the skin behaves.

This is one of the reasons consistency became so important in the way I think about formulation.

How greater consistency supports the skin

Biotechnology allows ingredients to be developed with greater control and reproducibility, which can help reduce some of that variability from the beginning. ³  When ingredients are created consistently, the skin is often exposed to fewer unknowns with consistent use.

For some people, this can help create a more stable and predictable experience with skincare. Not because biotechnology forces the skin to behave differently, but because its environment surrounding the skin becomes more consistent and supportive.

This way of thinking also aligned closely with the skin microbiome. The microbiome is constantly responding to its environment, including the ingredients applied to the skin and the overall condition being created on the surface of the skin itself. ⁶ 

When formulation becomes considered, skin often becomes easier to understand. Not perfectly controlled, but calmer, more comfortable, and more predictable in how it responds day to day.

A More Considered Approach to Formulation

One of the things biotechnology makes possible is a controlled approach to formulation.

When ingredients are developed with greater consistency, formulators are often able to work with them more precisely. This does not necessarily mean using more ingredients or stronger concentrations. In many cases, it allows for a restrained approach, where ingredients can be selected and combined with greater intention. ⁷ 

Over time, I became less interested in how much could be added to a formulation, and more interested in how thoughtfully a formulation could be built.

Why this matters for reactive or unsettled skin

This is especially important when working with skin that already feels unsettled, reactive, or overwhelmed. In these situations, adding more activity to the skin is not always what creates a better outcome. Often, the skin responds comfortably when unnecessary complexity is reduced.

Biotechnology supports this way of thinking because it allows ingredients to be developed with a level of consistency that can help reduce some of the unpredictability found in formulation.

For me, this is not about creating "high-performance" skincare in the traditional sense. It is about creating formulations that work in closer alignment with the skin, where ingredients are selected not only for what they do individually, but for how they behave together.

The goal is not to overwhelm the skin into change, but to support an environment where the skin can function comfortably and consistently.

This is also why biotechnology and microbiome thinking often sit naturally alongside each other. Both reflect a more connected understanding of skin, where compatibility, balance, and environment matter just as much as individual ingredients themselves.

Three qualities biotechnology can bring into ingredient development:

How Biotechnology Differs From Traditional Approaches

Traditional skincare ingredients are often sourced directly from plants, minerals, or marine environments. Many of these ingredients have been used in skincare for generations and continue to play an important role in formulation.

At the same time, naturally sourced ingredients can vary depending on climate, soil conditions, harvesting methods, processing, and seasonal change. ⁴  This variability is part of nature itself.

Biotechnology offers another way of working with ingredients. Instead of relying on direct extraction, ingredients can be created or refined through controlled biological processes, allowing for greater consistency in how they are produced and how they behave with consistent use. ²

This does not mean biotechnology is replacing nature. In many ways, it is still working with nature, simply through a controlled and considered process.

For me, this distinction matters because skin often responds best when unnecessary variability is reduced. That does not mean every natural ingredient is problematic, or that biotechnology is automatically better. It simply means that consistency can matter, particularly for skin that already feels reactive, overwhelmed, or difficult to understand.

Beyond consistency: sustainable sourcing benefits

Biotechnology can also offer advantages beyond consistency alone. In some cases, it allows ingredients to be developed with less dependence on large-scale harvesting, seasonal variation, or resource-intensive extraction methods. ¹⁰ 

While this is not the primary reason biotechnology interests me, I do think it reflects a responsible direction for ingredient development.

I think this is where some of the misunderstanding around biotechnology comes from. People often assume biotechnology makes skincare feel less natural or more synthetic, when in reality many biotechnology-derived ingredients originate from natural sources or biological processes themselves. ⁹ 

What interests me most is not whether an ingredient sounds natural or scientific. It is whether it has been developed thoughtfully, whether it behaves consistently, and whether it works comfortably with the skin day to day.

This way of thinking moves the conversation beyond trends and toward something considered. Not perfection, and not intensity, but an informed and balanced approach to supporting the skin.

Biotechnology and the Skin Microbiome

The skin microbiome is highly responsive to its environment. Everything applied to the skin has the potential to influence that environment, including the balance of moisture, lipids, pH, and overall skin comfort. ⁶ 

This is one of the reasons I became increasingly interested in the relationship between biotechnology and the microbiome. Both reflect a more connected way of thinking about skin.

Rather than viewing the skin in isolation, microbiome science considers the skin as part of a living ecosystem, where balance and compatibility matter. Biotechnology supports this approach by allowing ingredients to be developed with greater consistency and precision, which can help create formulations that work comfortably alongside the skin environment.

For me, microbiome-compatible skincare is not about trying to control the skin. It is about supporting the conditions the skin depends on to function well.

The principles behind microbiome-compatible skincare

This often comes back to the same principles again and again. Consistency. Compatibility. Restraint. Understanding how ingredients behave together, not only individually.

When skin is constantly being overloaded, disrupted, or pushed toward extremes, it can become harder for the skin to maintain balance. Over time, this may affect not only how the skin looks, but also how comfortable and predictable it feels day to day. ⁸ 

This is why biotechnology feels so aligned with the way I think about formulation. Not because it is futuristic, but because it allows for a thoughtful and controlled approach to developing ingredients that work in closer alignment with the skin and the microbiome that supports it.

The goal is not perfection. It is creating formulations that respect the skin as a living system, and support an environment where the skin can function comfortably.

What Biotechnology Makes Possible

Biotechnology allows ingredients to be developed with a level of consistency and definition that can be difficult to achieve through traditional methods alone. ³ 

For me, what makes this meaningful is not the technology itself, but what it allows formulators to do with greater intention.

When ingredients are developed consistently, formulations can often become refined and considered. The focus shifts away from excess and toward understanding how ingredients interact with the skin.

Three benefits of biotechnology in skincare

Three specific advantages of biotechnology are worth naming directly:

Consistency. Ingredients can be developed with reliable structure and behaviour between batches, reducing the variability the skin is exposed to.

Compatibility. Biotechnology allows ingredients to be designed with the skin and the microbiome in mind, supporting formulations that sit comfortably alongside the skin's natural environment.

Responsibility. Many biotechnology processes reduce dependence on large-scale harvesting and seasonal variation, allowing ingredients to be produced with less environmental cost. ¹⁰ 

This reflects a broader shift in the way skincare is evolving. Moving away from the idea that stronger is always better, and toward a more connected understanding of skin as a living system.

Biotechnology supports this direction by allowing ingredients to be developed with greater precision from the beginning, helping formulators create products that work comfortably alongside the skin and the microbiome that supports it.

It also allows conversations around formulation to become thoughtful. Not only about what ingredients are used, but how they are created, how consistently they behave, and how they contribute to the overall experience of the skin.

This does not mean biotechnology replaces the importance of good formulation, restraint, or understanding the skin itself. But I do believe it offers a considered direction for skincare. One that supports greater consistency, greater responsibility, and a closer alignment with the skin.

For me, that is what biotechnology makes possible. Not more complexity, but a more thoughtful way of supporting the skin over time.
