Which skin conditions can be mistaken for acne?

Many people assume that any red bumps or spots on the face must be acne. However, several skin conditions can look very similar and are sometimes mistaken for acne, particularly when symptoms first appear.

This can be frustrating because treatments that work well for acne may not improve other skin conditions. In some cases, they can even make symptoms worse.

Acne or rosacea?

Rosacea often causes redness across the cheeks, nose, forehead and chin. Small red bumps and pus-filled spots can develop, making it easy to confuse with acne, although rosacea usually does not cause blackheads. Many people with rosacea also notice flushing, visible blood vessels and increased skin sensitivity.

Acne or folliculitis?

Folliculitis occurs when hair follicles become inflamed, often due to irritation, infection or friction. It can create clusters of small red bumps and pustules that closely resemble acne and can appear on the face, chest, back and scalp. The spots are often very similar in size and may feel itchy rather than painful.

Acne or perioral dermatitis?

Perioral dermatitis usually causes small red bumps around the mouth, nose and sometimes the eyes. Skin may appear dry, irritated or flaky but unlike acne, blackheads are usually absent. Certain skincare products and steroid creams can sometimes trigger or worsen the condition.

Acne or keratosis pilaris?

Keratosis pilaris develops when keratin builds up within hair follicles, creating small rough bumps that are often described as feeling like sandpaper.

Although it is most common on the upper arms and thighs, it can also affect the face and be mistaken for acne. The bumps are usually flesh coloured or slightly red rather than the inflamed spots that you associate with acne conditions.

Final thoughts

Not every bump, spot or breakout is acne. Conditions such as rosacea, folliculitis, perioral dermatitis and keratosis pilaris can all look similar, particularly in the early stages.

If treatments designed for acne are not helping, or if your symptoms seem unusual, it may be worth considering whether another skin condition could be responsible. A correct diagnosis is often the first step towards finding the most effective treatment.
