Why your skincare might be drying your skin: the role of pH in melanin-rich skin 👉🏾

If your skin feels tight or dry after cleansing, the issue may beyour pH.

QUICK READ

Your skin is not meant to be neutral. It is meant to be acidic.

Studies suggest that melanin-rich skin may operate within a slightly more acidic range, which plays a key role in barrier function, lipid organization, and hydration retention.

When this acidic balance is disrupted, the skin barrier becomes less efficient, leading to dryness, sensitivity, and increased water loss.

Cleansing and toning are often where this disruption begins.

That is why GALSKIN cleanser and mist are formulated to respect the skin’s natural acidity, helping preserve barrier integrity and long-term resilience in melanin-rich skin.

Your skin is not neutral. It is acidic.

The surface of the skin is covered by what is known as the acid mantle.

This layer typically has a pH between 4 and 5.5 and plays a central role in maintaining skin health.

This acidity regulates:

• enzymes responsible for lipid production
• the organization of the skin barrier
• the balance of the skin microbiome

When the skin remains within this acidic range, these processes function efficiently.

Acidity is not a detail. It is a system.

Melanin-rich skin and acidity

Research suggests that melanin-rich skin may exhibit a slightly lower, more acidic surface pH compared to lighter skin types.

This more acidic environment can support:

• stronger barrier cohesion
• more efficient lipid processing
• improved defense against external stress

However, this balance is not static. It depends on maintaining the right conditions at the skin surface. Melanin-rich skin does not need correction. It needs stability.

What happens when pH is disrupted

When the skin shifts toward a more alkaline state, even temporarily:

• enzymes involved in lipid production become less efficient
• the structure of the barrier becomes less organized
• transepidermal water loss increases
• the skin becomes more reactive

In practice, this can appear as:

• tightness after cleansing
• dryness despite using skincare
• increased sensitivity to products
• higher risk of irritation (a key trigger for hyperpigmentation)

For melanin-rich skin, this last point is critical, as irritation is more likely to lead to visible uneven tone or post-inflammatory marks.

Cleansing is where disruption begins

Cleansing is one of the most common causes of pH disruption.

Many cleansers temporarily raise the skin’s pH, especially those that are strongly foaming or formulated at a higher pH.

Even if the skin returns to its normal state afterward, repeated disruption can affect barrier stability over time.

This is why skin can feel clean, but also tight, dry, or uncomfortable immediately after washing.

Cleansing should not disrupt your skin.

Show me the research

This is not marketing. It is based on skin physiology.

Studies have shown that skin surface pH plays a key role in regulating enzymes responsible for lipid synthesis and barrier repair.

Research has also demonstrated that barrier recovery is slower when the skin is exposed to higher, more alkaline pH levels.

Some studies comparing skin types have reported a lower surface pH in Black skin compared to white skin, suggesting a more acidic baseline environment.

At the same time, the literature remains heterogeneous, and these differences should be understood as tendencies rather than absolute rules.

What is consistently observed is the impact of pH disruption onbarrier function.

Why this matters

If the skin’s acidic balance is repeatedly disrupted, the barrier becomes less efficient at retaining hydration.

This creates a cycle where the skin feels dry, even when products are applied.

For melanin-rich skin, this instability can also increase sensitivity and the risk of uneven tone over time.

Maintaining the right pH is not an extra step. It is a foundation.

Why GALSKIN focuses on pH

At K+BROWN, we approach skincare as a system.

That system starts with preserving what the skin already does well.

That is why GALSKIN cleanser and mist are formulated with a pH close to that of healthy skin.

• to help maintain the acid mantle
• to support barrier function
• to preserve hydration and resilience over time

The goal is not to change the skin, but to protect its natural balance.
