Benign skin lesions

What are benign skin lesions?

Over time, the skin undergoes small changes: spots, bumps, roughness or growths which, although often benign, need to be examined by a dermatologist and treated if we want to improve the appearance of the skin, adapting it to each person's preferences and the location of the lesions.

Seborrheic keratoses

These are very common benign lesions that appear after the age of 40. They appear as brown, black or skin-coloured patches with a rough surface and a wart-like appearance.

Why do they appear?

Genetic factors and skin ageing.

Is it necessary to treat them?

It is not mandatory, but many people choose to remove them for aesthetic reasons. They can be treated with cryotherapy, curettage, or laser.

Solar lentigines - sun spots

They are flat, brown spots that appear on areas exposed to the sun (face, hands, neckline). Unlike moles, they are not congenital but acquired through accumulated sun damage.

Can they be treated?

Yes, with treatments such as laser, intense pulsed light (IPL) or depigmentation peels.

Ruby angiomas or red spots

Small, bright red spots or bumps caused by dilated blood vessels. They are completely benign and very common on the trunk and limbs.

What is the treatment like?

They are easily removed with vascular laser or electrocoagulation.

White fibroids or skin tags

They are small, flesh-coloured flaps of skin that usually appear on the neck, armpits, eyelids or groin. They tend to increase with age or due to friction.

Nevus - common moles

Although they often serve an aesthetic purpose, some moles can change over time. It is important to differentiate between benign nevi and suspicious lesions.

Frequently asked questions about acne and rosacea

I understand that you may have questions and concerns about acne and rosacea. Below, I answer some of the most frequently asked questions from my patients:

What is acne?

Acne is an inflammatory skin condition that occurs when hair follicles become clogged with oil (sebum), dead skin cells and bacteria. This causes blackheads, whiteheads, pimples and, in some cases, cysts to appear.

Do only teenagers suffer from acne?

No. Although it is common in adolescence, acne also affects adults, especially women between the ages of 20 and 35. It is estimated that almost 30% of women in that age range suffer from it.

Can acne be cured just by following a good skincare routine?

Not always. Although a proper skincare routine can help, many cases of acne require medical treatment, which may include topical products, oral medications, or procedures such as laser therapy.

What causes acne?

Acne can have multiple causes: genetic factors, hormonal changes, stress, diet, and other lifestyle factors. That is why a personalised approach to diagnosis and treatment is important.

What types of treatment are available for acne?

Treatment depends on the type and severity of acne. It may include:

Topical medication (creams or gels)
Oral treatment (antibiotics, contraceptives, retinoids)
Laser treatments, both to reduce acne activity and to treat scars

Is it true that acne cannot be cured if I have had it for many years?

False. Although it is a persistent condition, there are multiple treatment options that can significantly improve acne and even eliminate it. It is never too late to start effective treatment.

Do stress and diet influence acne?

Yes. Stress can affect hormonal balance and worsen acne. Likewise, a diet rich in sugars and ultra-processed foods can have a negative impact on the skin. These factors are important when designing a comprehensive treatment plan.

Can acne leave permanent scars?

Yes, especially if it is not treated properly or if the spots are excessively manipulated. That is why it is important to see a dermatologist as soon as possible to prevent long-term scarring.
