One of the most common misconceptions I hear in clinic is that warts are simply a cosmetic issue that will eventually disappear on their own.
While some do resolve naturally, many can persist for months or even years, spreading to surrounding skin or becoming increasingly difficult to treat. In my experience, early assessment often leads to simpler and more effective management.
Throughout my career, I’ve been passionate about helping patients understand that healthy skin is about far more than appearance. Whether I’m treating inflammatory skin conditions, pigmentation concerns, or common viral infections like warts, my goal is always the same — to provide evidence-based care that supports long-term skin health.
Modern dermatology is not about chasing quick fixes. It’s about understanding the biology of the skin, selecting the right treatment for the individual, and giving patients the confidence to take control of their skin journey.
Every day, I’m reminded that even small skin concerns can have a significant impact on quality of life. Helping someone finally resolve a stubborn wart after years of frustration can be just as rewarding as treating far more complex conditions.

One of the reasons I chose dermatology is that skin tells a story.
A tiny spot on the hand, a persistent bump on the foot, or a lesion that someone has ignored for years can often reveal much more than people realise. Viral warts are a good example. They’re incredibly common, affecting children and adults alike, yet many patients delay seeking advice because they feel embarrassed or assume nothing can be done.
Over the years, I’ve developed a strong interest in combining clinical dermatology with patient education. I believe understanding your skin is just as important as treating it. Whether that means discussing prevention, explaining why a treatment takes time, or reassuring someone that they’re not alone, those conversations matter.
At our clinic, we focus on thoughtful, evidence-based care. Every patient deserves an individual approach because no two skin conditions — or people — are exactly the same.
Healthy skin contributes to confidence, comfort, and overall wellbeing. That’s what continues to inspire my work every day, and why I remain committed to advancing skin health through education, research, and compassionate care.

Flat warts are small, smooth, slightly raised skin growths caused by certain strains of the human papillomavirus (HPV). Unlike common warts, flat warts are usually tiny, have a flatter surface, and often appear in clusters. They are most commonly found on the face, forehead, neck, hands, and legs.Flat warts are more common in children, teenagers, and young adults, but they can occur at any age. The virus spreads through direct skin contact or through small cuts and irritation caused by shaving, scratching, or friction. Because they are contagious, flat warts may spread to nearby areas of the skin if touched frequently.These warts are typically skin-colored, pink, or light brown and are usually painless.

Moles vs. Skin Tags: Deciphering Your Skin's MysteriesThe Dilemma of Diagnosis

While both moles and skin tags are common skin growths, they have distinct characteristics and implications. Patients often come to the clinic with a preconceived notion of their condition, sometimes based on internet searches, leading to confusion about the actual diagnosis. It is essential to refer to these growths correctly, whether as moles, skin tags, lesions, or unknowns, to ensure proper treatment.

Moles: More Than Meets the Eye

Moles are collections of melanocytes, cells that give skin, eyes, and hair their color. Often formed due to UV radiation exposure, moles are typically darker than skin tags and can appear in shades of tan, brown, or black. Firm, with a wide base, they can emerge anywhere on the skin. While most are benign, some moles can develop into melanoma, a serious skin cancer. Changes in size, shape, or color should prompt a consultation with a dermatologist.
1.Formation and Characteristics: Moles are collections of melanocytes, the cells responsible for skin, eye, and hair color. They often form due to ultraviolet (UV) radiation exposure.
2.Appearance: Moles are typically darker than skin tags, appearing in shades of tan, brown, or black, although dermal moles can be flesh-colored.
3.Location and Structure: They can form anywhere on the skin and are usually firmer, larger, and have a wider base compared to skin tags. Moles do not protrude on a stalk-like skin tags.
4.Potential Risks: While generally benign, moles can potentially develop into melanoma, a form of skin cancer. Changes in size, shape, or color, as well as the development of asymmetry or irregular borders, can be warning signs.
Skin Tags: An Annoying but Benign Guest

On the other hand, skin tags are benign growths composed of skin, blood vessels, fat, and sometimes fibrous tissue. They tend to form in areas of friction like the neck, underarms, or groin. Generally matching your skin color or slightly darker, skin tags protrude on a stalk or pedicle and are more of a nuisance than a health risk. However, irritation or snagging on clothing and jewelry is common.

1.Formation and Characteristics: Skin tags are benign growths made of skin, blood vessels, fat, and sometimes fibrous tissue. They often form in areas where skin rubs against skin or clothing, like the neck, underarms, or groin.
2.Appearance: They are usually the same color as your skin or slightly darker. Skin tags protrude from the skin, often on a stalk or pedicle.
3.Common Locations: They are commonly found in skin folds or areas experiencing friction.
4.Health Implications: Skin tags are generally noncancerous and not dangerous. However, they can become irritated or caught on clothing and jewelry.
