What are the most common skin problems people face today and what factors are driving them? In recent years, skin fungal infections have become one of the most frequently encountered problems, especially during the summer season. The rise in temperature leads to increased sweating, which creates moist environments on parts of the body like the inner thighs and underarms. These areas become prone to fungal infections due to constant dampness. Additionally, heat-related conditions such as miliaria, commonly known as prickly heat or ‘pitt’ in Punjabi, are also common during hot weather. Prolonged exposure to the sun leads to sunburns and other forms of skin irritation. All of these are largely driven by environmental conditions, especially heat and humidity, as well as poor personal hygiene and wearing non-breathable clothing.

Many new skincare treatments like PRP and laser therapies are gaining popularity. Do these have any side-effects or risks people should be aware of?

Modern therapies like PRP (Platelet-Rich Plasma) treatment and laser procedures have revolutionised the field of dermatology by offering solutions for hair loss, pigmentation, acne scars and skin rejuvenation. However, it is very important for people to understand that these procedures carry potential risks and should only be performed by a qualified dermatologist who holds a proper medical degree—specifically, an MD in Dermatology. Unfortunately, many unqualified practitioners or so-called “skin experts” without medical credentials are offering these services. In the wrong hands, these treatments can result in burns, infections, scarring and long-term skin damage.

How much do diet, stress and lifestyle truly affect the skin’s appearance and health? Diet and lifestyle have a considerable impact on skin health, more than most people realise. For example, consuming oily, fried, or spicy foods can trigger acne and pimples, especially in individuals with oily or sensitive skin. Similarly, alcohol and red meat consumption have been observed to worsen chronic skin conditions such as psoriasis. Diets high in calories and sugar often lead to weight gain, which can in turn cause skin thickening and dark patches, a condition known as Acanthosis Nigricans. Stress also plays a major role. It affects hormone levels, which can lead to increased oil production and inflammation, making skin conditions worse.

There’s a lot of skincare advice online—what are some common myths or misconceptions you frequently correct? One of the biggest concerns I face in my practice is the increasing trend of self-treatment based on online skincare advice. Social media platforms and websites are filled with product recommendations and home remedies, many of which are not backed by science. I often see teenagers using multiple serums, face washes, or sunscreens simply because they saw someone online recommend them. A common myth is that natural or herbal products are always safe, but many of them contain allergens or strong ingredients that may irritate the skin. People must understand that every individual has a different skin type and what works for one person may harm another. It’s crucial not to follow trends blindly and instead consult a qualified dermatologist for proper skin assessment and treatment.
