Sweating is one of the body’s most important thermoregulation mechanisms.
During exercise, the body generates heat due to increased metabolic activity in the muscles. To maintain a safe internal temperature, the sweat glands are activated, releasing sweat onto the surface of the skin.

As sweat evaporates, it helps cool the body—allowing physical activity to continue without overheating (Shibasaki & Crandall, 2010).

However, intense sweating also directly affects the skin’s microenvironment.

Sweat and the Skin Barrier

Sweat is primarily composed of water, but it also contains:

– Electrolytes (sodium, potassium, chloride)
– Urea
– Lactic acid
– Small amounts of proteins

Under normal conditions, sweat helps maintain skin hydration and supports the natural pH balance.

However, when it remains on the skin for prolonged periods—especially during intense physical activity—it can create conditions that disrupt the function of the skin barrier.

Extended exposure to sweat may lead to:

– Increased transepidermal water loss (TEWL)
– Irritation
– Alterations in the skin microbiome
(Kanda et al., 2013)

Sweat + Friction: A Common Trigger for Irritation

During exercise, sweat is often combined with mechanical friction caused by:

– Athletic clothing
– Equipment
– Repetitive movements

Moisture on the skin’s surface can increase friction between the skin and fabric, leading to:

– Irritation
– Redness
– Micro-inflammation

This effect is especially common in areas such as:

– Neck
– Face
– Shoulders
– Back

The Role of Proper Skincare Preparation

For individuals who exercise regularly, preparing the skin before training can help maintain its balance and resilience.

Using products that:

– Strengthen the skin barrier
– Provide antioxidant protection
– Support hydration

can help the skin better adapt to the conditions of physical activity.

The Active Skin Routine Before Exercise

At KOFEA, the Active Skin approach is built on a simple idea:
your skin needs the same level of preparation as your body before training.

A simple routine includes:

Silken Serum – Antioxidant Serum

A lightweight serum that absorbs quickly and delivers antioxidant protection to the skin.

Silver Skin – Antioxidant Cream

A reinforcing cream that helps protect the skin barrier and maintain balance during exercise.

Together, they create a protective skincare base before your workout.

Sweat Is Natural — Protection Is Essential

Sweating is a natural and essential part of exercise.
With the right skincare preparation, we can support the skin barrier and protect the skin from the stress of physical activity.

At KOFEA, we believe skincare should evolve alongside our lifestyle.
For those who move every day, pre-workout skin preparation is not optional—it’s essential.
