01 — ACNE & RELATED CARE · Acne, Post-acne Marks & Acne Scars

Acne, marks and scars may need different starting points

Active acne, marks from earlier spots
and changes in skin texture can all be present at the same time.

Care should begin by understanding what is happening with your skin now, before choosing a method.

This page provides general information for understanding. It does not offer a diagnosis or individual treatment advice.

The word “acne” often describes
several things happening at once

Acne Red marks Dark marks Uneven texture

Different concerns often described as “acne”

What you see on your skin today may not all come from the same process.

Many people begin a consultation by saying, “I have acne.” That is understandable, but an assessment may reveal new spots, marks from earlier acne or changes in texture. Often, more than one concern is present at the same time.

Making this distinction is not about naming a condition. It helps us begin the conversation with a shared understanding of which concern we are discussing.

Before choosing what to do,
first identify
what concerns you now

All three can coexist on the same skin, but they mean different things and can affect where care begins.

ACNE SCARS / TEXTURE
What it is

New spots appearing or inflammation that is still present.

Changes in colour after acne settles, such as red or dark marks.

Changes in texture after deeper inflammation, such as uneven or pitted skin.

Why it matters
for the order of care

If new spots are still appearing, the active concern may affect decisions about other concerns that follow.

Marks are different from active acne and may need separate consideration. Red and dark marks may also differ.

When texture changes, assessment becomes even more individual.

What you can share
with your doctor

Whether new spots are still appearing, where they often occur and how long this has been happening.

How long the marks have been present, whether they look red or dark, and whether new marks are appearing.

Where your skin looks or feels less smooth, and how much this concerns you.

01

Active inflamed acne

What it is

New spots appearing or inflammation that is still present.

Why it affects priorities

An active concern may influence decisions about other concerns that follow.

02

Post-acne marks

What it is

Changes in colour after acne settles, such as red or dark marks.

Why it affects priorities

Marks are different from acne and may need separate consideration.

03

Uneven texture and acne scars

What it is

Changes in texture after deeper inflammation.

Why it affects priorities

Assessment becomes even more individual.

01

Active inflamed acne

New spots or ongoing inflammation may influence other concerns that follow.

02

Post-acne marks

Red or dark marks after acne settles are different from acne itself and may need separate consideration.

03

Uneven texture and acne scars

Texture changes after deeper inflammation need an individual assessment.

You do not need to distinguish everything yourself before coming in. Knowing what concerns you most is enough to start the conversation.

These three categories are here to support understanding. They are not a self-assessment tool. A doctor needs to assess your skin’s condition.

If new spots keep appearing,
what is happening now
may take priority over what remains

When new spots continue to appear, care may need to begin with the active concern, as the skin is still changing.

This does not mean everyone with inflamed acne should begin with the same approach. Your skin’s characteristics, the affected areas and what you have already tried all influence the assessment.

This page does not specify medicines, products or acne treatments, as these depend on an individual assessment.

The marks that remain
are different from active acne

After a spot settles, a change in skin colour may remain. This is different from active acne and should not automatically be called a pitted acne scar or a scar.

Red marks

Red or pink colour that remains where acne was present, after the spot has settled.

Dark marks

Colour that is darker than the surrounding skin and may develop after inflammation.

Red and dark marks may look similar at a glance, but they are not necessarily the same concern. They may change at different rates and need different considerations.

If new acne spots are still appearing, new marks may develop at the same time. This is one reason active acne can influence decisions about marks.

When what remains
is more than colour
and skin texture has changed

Colour Red marks · Dark marks · Section 05 Section 05
Texture Uneven skin · Acne scars · This section This section

Uneven skin and pitted acne scars are changes in texture that may follow deeper inflammation. They are distinct from active acne and from changes in colour left after acne.

When texture changes, assessment becomes even more individual. The appearance, location and overall skin condition vary between people. What suits one person may not be the starting point for another.

Texture changes call for an individual assessment by a doctor in person, rather than from photographs.

Your biggest concern
may not always be
the first priority for care

Many people come in most concerned about scars or marks. That concern is understandable. If new acne spots are still appearing, however, the skin’s current condition may influence what should take priority.

At the same time, not everyone needs to follow the same sequence.

Your question

What concerns me most?

The assessment question

What should we address first for my skin now?

These questions may have the same answer or different answers. Both are part of the conversation.

The order of care should not be decided in advance from photographs or the name of a concern alone.

What matters to you

Skin that irritates easily
may change how we approach acne

Some people have acne alongside redness, stinging or easily irritated skin. In this situation, a doctor may consider the skin’s overall condition before deciding how to approach acne care.

This page focuses on acne. Fragile skin, irritation and skin recovery are covered on a separate page.

As your skin changes,
the priorities
may change too

What takes priority today may be different at another stage. The balance between active acne, remaining marks and changes in texture may shift.

Follow-up helps us observe how your skin changes and review whether the original priorities still fit.
