You should see a dermatologist if you notice a new or changing mole, persistent rash, unexplained hair loss, nail discoloration, acne, or any skin concern lasting more than two to four weeks. Early diagnosis leads to faster, more effective treatment and prevents minor issues from becoming complex conditions. An annual skin check is also recommended even when you have no active complaints.

Dermatologists diagnose and treat more than 3,000 conditions affecting the skin, hair, and nails. These include acne, eczema, psoriasis, fungal infections, vitiligo, melasma, androgenetic alopecia, alopecia areata, onychomycosis (nail fungus), skin tags, warts, cysts, and skin cancers. They also perform cosmetic procedures such as chemical peels, laser treatments, and anti-ageing injectables to improve skin texture, tone, and appearance.

While social media influencers can raise awareness about skincare, their recommendations are not based on clinical evaluation and may not be suitable for your unique skin type, tone, or underlying condition. Products promoted online can cause allergic reactions, worsen acne, trigger post-inflammatory hyperpigmentation, or disrupt your skin barrier - especially if you have conditions such as rosacea, eczema, or melasma. Always consult a dermatologist for your skin, hair and nail concerns.

Every individual has a distinct skin type, Fitzpatrick skin tone, hormonal profile, lifestyle, and medical history. A product or treatment that works well for one person may irritate, darken, or damage another person’s skin. A qualified dermatologist evaluates all of these factors before designing a treatment plan. This personalised approach minimises side effects, maximises results, and avoids the trial-and-error that often leads to worsened pigmentation or prolonged breakouts.

The skin is closely linked to internal metabolic health. Diabetes can cause acanthosis nigricans (dark, velvety skin at skin folds), diabetic dermopathy, slow wound healing, and recurring fungal or bacterial infections. Thyroid disorders often present as dry, coarse skin, hair thinning, and brittle nails. Polycystic ovarian syndrome (PCOS) frequently causes acne, hirsutism, and hair loss. A dermatologist may identify these systemic conditions through skin signs even before a formal internal medicine diagnosis.

Yes, obesity has direct and indirect effects on skin health. Excess body weight increases friction between skin folds, raising the risk of intertrigo (skin fold inflammation), fungal infections, and stretch marks. Elevated insulin resistance associated with obesity promotes acne, skin tags, and acanthosis nigricans. Obesity also impairs skin barrier function, delays wound healing, and increases the risk of chronic inflammatory skin conditions such as psoriasis and hidradenitis suppurativa.

Losing 50 to 100 strands per day is considered within the normal range. However, if you notice rapid or diffuse thinning, bald patches, receding hairline, or shedding after illness, stress, or childbirth that continues beyond three months, you should consult a dermatologist. Hair loss can be caused by nutritional deficiencies, thyroid imbalance, scalp infections, genetic androgenetic alopecia, or autoimmune conditions - all of which require different treatment approaches.

For Indian skin tones (Fitzpatrick types IV-VI), a broad-spectrum sunscreen with SPF 30 or higher and PA+++ or PA++++ rating is recommended. Look for formulations that are lightweight, non-comedogenic, and free from heavy occlusives that can worsen oiliness or fungal acne. Chemical sunscreens with filters like octinoxate or physical sunscreens containing zinc oxide both offer protection. A dermatologist can help you choose the right SPF formulation based on your skin type, daily sun exposure, and any underlying pigmentation concerns.

Many traditional home remedies such as lemon juice for brightening, turmeric for glow, or toothpaste for acne, can damage the skin barrier, cause chemical burns, trigger allergic contact dermatitis, or worsen pigmentation due to phototoxic reactions. The skin has a delicate pH balance that is easily disrupted by acidic or alkaline kitchen ingredients.
