Why Cosmetology Education Must Evolve for Melanin-Rich Skin

The beauty industry has become considerably more inclusive in the faces it represents, but education has not always evolved at the same pace.

Beauty professionals today will work with people across every skin tone, yet the biology, presentation and treatment considerations of melanin-rich skin can still be taught as an additional or specialist subject rather than as part of fundamental cosmetology education.

That needs to change.

Understanding Black and Brown skin should begin with the first lesson in skin biology and continue through consultation, treatment selection, practical training and aftercare. This is not simply about diversity or representation. It is about giving future professionals the knowledge to make safer decisions for the skin in front of them.

We Need to Start With the Biology

We all have melanocytes, the cells responsible for producing melanin. The number of melanocytes does not dramatically increase simply because somebody has darker skin. The important differences lie in how melanin is produced, packaged and distributed.

In more deeply pigmented skin, melanosomes, the structures that contain melanin, tend to be larger and more individually dispersed within surrounding skin cells. This contributes to deeper pigmentation and also helps explain why inflammation can have such a visible and persistent consequence in skin of colour.

This is one of the most important concepts I believe a beauty professional should understand.

When melanin-rich skin experiences inflammation, whether from acne, friction, a burn, an inappropriate treatment or excessive exfoliation, the melanocytes can respond by producing additional pigment. This can result in post-inflammatory hyperpigmentation, or PIH.

PIH occurs in every skin tone but is particularly common and can be more persistent in darker skin. Research consistently recognises skin of colour as having a greater tendency to develop pigmentation following inflammation or injury.

I often describe the principle very simply: one scratch, one bite or one burn, and we hyperpigment.

For a practitioner, understanding that one principle can completely change how they approach treatment.

Irritation Is Not Evidence That a Treatment Is Working

Beauty education has historically celebrated intensity.

A stronger peel, a deeper exfoliation or a visible reaction can sometimes be interpreted as evidence that a treatment is effective. With pigmentation-prone skin, that mindset can be problematic.

If a treatment creates unnecessary inflammation, the consequence may not end when the redness or irritation disappears. The client can be left with pigmentation that remains for weeks or months afterwards.

This is why my approach to skin of colour has always centred on minimising inflammation while achieving the desired result.

Gentle does not mean ineffective.

In many cases, controlled and consistent treatment is far more appropriate than pursuing the strongest possible intervention. Students should therefore be taught not simply how to perform a treatment, but how to recognise when the intensity of that treatment is inappropriate for a particular client.

That principle applies to exfoliation, peels, extractions, hair removal and many other procedures performed within the beauty industry.

The Skin Barrier Must Be Part of the Conversation

Pigmentation should never be taught in isolation from skin-barrier health.

Ceramides are an important component of the stratum corneum and help the skin retain moisture and maintain an effective barrier. Research examining ethnic differences in skin has reported lower stratum-corneum ceramide levels in Black skin in some populations compared with White and certain other ethnic groups.

This matters because when the barrier is compromised, skin becomes more vulnerable to dryness and irritation. And in pigmentation-prone skin, irritation can become the trigger for further pigmentation.

For me, this creates a simple chain that students should understand:

Barrier disruption → inflammation → melanocyte stimulation → increased risk of pigmentation.

That is why education for melanin-rich skin cannot focus solely on how to remove pigment. Professionals need to understand how to avoid creating it in the first place.

Barrier support, hydration and avoidance of unnecessary irritants should therefore be taught alongside active treatment.

Students Also Need to Recognize Inflammation Differently

Another important educational gap is visual diagnosis.

Many textbooks and training materials have historically illustrated inflammation predominantly on lighter skin. Students become accustomed to looking for bright redness as a sign of irritation.

But inflammation does not always present that way in deeper skin tones. Depending on skin depth and the condition involved, erythema can look subtler, darker, violaceous, greyish or brown rather than bright pink or red.

If students are never shown these presentations during training, how can we expect them to recognise an adverse reaction confidently once they qualify?

Inclusive education therefore requires much more than adding photographs of darker skin to a presentation. Students need repeated exposure to different skin tones in case studies, demonstrations and practical assessments.

Avoiding Inflammation Should Be a Fundamental Principle

Another pillar of my approach is reducing unnecessary sources of irritation.

Fragrance, denatured alcohol, essential oils, overly aggressive acids and physical abrasion can all potentially irritate susceptible skin. This does not mean every ingredient will cause a reaction in every individual, but professionals working with pigmentation-prone clients should understand that irritation has consequences.

The aim should not be fear of active ingredients. It should be intelligent selection.

Students should understand concentration, frequency, skin-barrier status and how multiple treatments interact. They should know why continually escalating treatment strength is not always the fastest route to improvement.

Sometimes the most sophisticated decision a practitioner can make is to do less.

Sun and Visible Light Education Also Matters

There remains a persistent misconception that people with darker skin do not need sun protection because melanin offers some natural protection against UV radiation.

Melanin does provide a degree of photoprotection, but it does not make darker skin immune to UV damage or pigmentation.

For clients experiencing PIH or melasma in particular, light exposure can maintain or worsen unwanted pigmentation. Understanding photoprotection should therefore be part of pigmentation education for every skin tone.

Students should graduate understanding that preventing pigmentation is not only about what happens during a treatment. It also involves appropriate preparation and aftercare.

What Should Inclusive Cosmetology Education Look Like?

I do not believe skin of colour requires an entirely separate curriculum.

I believe it needs to be integrated into the existing curriculum from beginning to end.

Students should qualify knowing how pigmentation biology differs across skin tones, how inflammation can trigger PIH, how the skin barrier influences treatment tolerance, how irritation may present differently and why treatment intensity needs to be individualised.

They should practise on a genuinely diverse range of skin tones rather than encountering Black and Brown skin only in theory.

Most importantly, they should learn that equality of care does not mean performing the identical treatment on every person.

True inclusivity is the ability to assess the individual, understand their risk factors and adjust the approach accordingly.

Skin of colour should not be viewed as a niche within modern cosmetology. Black and Brown clients are part of the everyday population that future beauty professionals will serve.

Training students to understand their skin is therefore not specialist education.

It is simply good education.
