Stretch Marks Explained: Causes and Skin Changes

Stretch marks are a common skin concern that can affect people of different ages, genders and skin types. Medically known as striae, they develop when the skin stretches or shrinks more quickly than it can naturally adapt. This process can affect the collagen and elastin fibres that help give the skin its strength and flexibility.

Although stretch marks are a natural part of the skin’s healing response and are not harmful, many people seek to understand why they occur and whether professional advice may be appropriate. Understanding stretch marks can help you make informed decisions about your skin health.

What Are Stretch Marks?

Stretch marks are long, narrow streaks or lines that form when the deeper layers of the skin are placed under increased tension. As the skin adjusts to rapid changes, tiny tears may develop within the dermis, leading to visible marks on the skin’s surface.

Their appearance changes over time and may vary according to your skin tone and the stage of healing.

Early Stretch Marks

Newly formed stretch marks often appear:

• Red
• Pink
• Purple
• Dark brown (on some skin tones)

They may also feel slightly raised or itchy during the early stages.

Mature Stretch Marks

As they mature, stretch marks generally become:

• White
• Silver
• Lighter than the surrounding skin
• Flatter and softer

The appearance differs from person to person.

What Causes Stretch Marks?

Stretch marks develop when the skin is required to expand or contract rapidly. Several factors may contribute to this process.

Pregnancy

Stretch marks commonly develop during pregnancy as the abdomen, breasts and hips undergo natural changes.

Puberty

Rapid growth during adolescence may lead to stretch marks on areas such as the thighs, hips, shoulders and lower back.

Rapid Weight Changes

Significant weight gain or weight loss may place additional stress on the skin and contribute to stretch mark formation.

Muscle Growth

People involved in strength training or bodybuilding may notice stretch marks as muscle mass increases.

Hormonal Changes

Hormonal influences may affect the skin’s elasticity and make some individuals more likely to develop stretch marks.

Genetics

Family history may play an important role in determining an individual’s likelihood of developing stretch marks.

Where Do Stretch Marks Commonly Appear?

Stretch marks may occur anywhere the skin experiences rapid stretching.

Common areas include:

• Abdomen
• Hips
• Thighs
• Buttocks
• Breasts
• Upper arms
• Lower back
• Shoulders

The location often depends on the underlying cause of the skin changes.

Who May Consider a Professional Skin Assessment?

A professional skin assessment may be appropriate if you:

• Have concerns about the appearance of stretch marks.
• Notice new stretch marks developing rapidly.
• Experience skin changes following pregnancy or weight changes.
• Are unsure whether your skin changes are stretch marks or another condition.
• Would like personalised advice regarding your skin concerns.

An assessment allows your clinician to evaluate your skin and discuss management options that may be appropriate for your individual circumstances.

What Happens During a Skin Assessment?

During your consultation, your clinician may evaluate several factors before discussing appropriate management options.

Skin Type

Your skin type and skin tone help guide personalised recommendations.

Age of the Stretch Marks

Early and mature stretch marks may present differently and are assessed accordingly.

Extent and Location

The number, size and location of the stretch marks are evaluated as part of the assessment.

Medical History

Your clinician may discuss relevant medical history, hormonal changes, pregnancy history or significant weight changes where appropriate.

This information helps provide recommendations based on your individual needs.

Supporting Healthy Skin

While stretch marks are a natural skin change, maintaining healthy skin habits may support overall skin health.

General recommendations include:

• Keeping the skin well hydrated.
• Using sunscreen on exposed skin.
• Following a consistent skincare routine.
• Maintaining a balanced diet.
• Seeking professional advice if you notice significant or concerning skin changes.
