Dr. Acharya answers the most common questions about treatments, procedures, and skin health — in plain, jargon-free language.
Melasma is a chronic pigmentation disorder characterised by brown or greyish patches — most often on the cheeks, forehead, upper lip, and nose. It is triggered by UV radiation, heat, hormonal fluctuations (especially oral contraceptive pills and pregnancy), and genetic predisposition.
Nepal's high-altitude UV exposure, combined with the prevalence of South Asian skin types (Fitzpatrick III–V) that are naturally more reactive to UV, makes melasma extremely common here. The condition is not harmful, but it significantly impacts confidence — and it requires long-term management, not a one-time fix.
Melasma is a chronic condition with a tendency to recur — especially with sun exposure or hormonal changes. While it cannot always be "cured" in the conventional sense, it can be effectively controlled to a point where it is barely visible. The key is consistent sun protection (SPF 50+ daily), appropriate maintenance therapy, and avoiding known triggers. Dr. Acharya's protocols achieve significant and lasting improvement in most patients, though ongoing care is important.
Laser treatment for melasma on darker skin tones (common in South Asia) requires specific expertise and equipment choice. Poorly selected laser parameters can worsen melasma — a phenomenon called post-inflammatory hyperpigmentation (PIH). Dr. Acharya uses carefully selected, low-fluence Q-switched Nd:YAG and fractional laser protocols specifically validated for Fitzpatrick III–V skin. When done correctly by an experienced dermatologist, laser can be very effective and safe for darker skin.
Visible lightening typically begins within 4 to 8 weeks of starting treatment. However, significant improvement usually takes 3 to 6 months. Patience is essential with melasma — rushed or aggressive treatment often leads to rebound. Results are maintained with daily sun protection and periodic maintenance sessions.
Adult acne — particularly in women over 25 — is often driven by hormonal fluctuations (menstrual cycle, polycystic ovarian syndrome/PCOS), stress, certain cosmetics (comedogenic products), and dietary factors (high glycaemic foods, dairy). Unlike teenage acne driven by surging androgens, adult female acne tends to be cyclical, concentrated around the jawline and chin, and often resistant to standard over-the-counter products. A dermatologist assessment is key to identifying the underlying driver.
The best approach depends on scar type — atrophic (pitted) scars respond best to microneedling with PRP, fractional CO2 laser, and subcision for tethered scars. Flat post-inflammatory hyperpigmentation (dark marks) is treated like pigmentation. Hypertrophic or keloid scars need intralesional injections. At Reva Skin and Hair Clinic, Dr. Acharya performs a thorough scar assessment and customises the treatment plan to each patient's specific scar types and skin tone.
Most patients see meaningful improvement after 3 to 6 sessions, spaced 4 to 6 weeks apart. Mild scars may respond adequately in fewer sessions; deeper, extensive scarring may require more. Results are gradual and cumulative. Combining modalities (for example, microneedling + PRP + laser) often yields better outcomes than any single treatment alone.
PRP (Platelet-Rich Plasma) is derived from your own blood — it is centrifuged to concentrate platelets that release growth factors to stimulate hair follicles and skin repair.
GFC (Growth Factor Concentrate) is a more refined form of PRP. It isolates and concentrates the specific growth factors (without unnecessary cells), producing a purer, more potent formulation that often yields faster and more consistent results than standard PRP.
Exosomes are nano-sized vesicles derived from stem cells. They carry signalling molecules, proteins, and microRNA that communicate with your own cells to stimulate regeneration. They represent the next frontier — exosomes can be used for both scalp and skin with remarkable results. Unlike PRP, they are not derived from the patient's own blood.
A standard course involves 3 to 4 sessions, each 4 weeks apart, followed by maintenance every 3 to 6 months. GFC typically shows results slightly faster than PRP, with some patients noticing reduced shedding within 4 to 6 weeks of starting. Results are gradual — significant density improvement becomes visible around 3 to 6 months into treatment. At Reva Skin and Hair Clinic, we ensure that you get the best results. We use authentic pharma-company manufactured GFC and it costs NRs. 10000 per session.
PRP and GFC scalp injections involve minimal discomfort. Topical anaesthetic cream is applied beforehand to maximise comfort. After the procedure, mild scalp tenderness and occasional swelling at injection sites may last 24 to 48 hours. Most patients return to normal activities the same day. There is no major downtime.
The price of exosomes treatment depends upon the quality and make of exosomes. This also determines the results you see with the treatment. At Reva Skin and Hair Clinic, we use authentic exosomes from Korea. This ensures maxmium benefits to your skin and hair concerns. A session costs NRs. 12000 at Reva.
At Reva Skin and Hair Clinic, we provide the highest quality exosomes and PDRN treatment directly sourced from Korea. And Yes — exosomes applied to the face (via microneedling) can dramatically improve skin texture, radiance, fine lines, and skin repair. They accelerate healing and boost collagen synthesis. Many patients combine exosome therapy with fractional laser for enhanced and faster outcomes. It is one of the most exciting frontiers in aesthetic dermatology today.
HIFU (High-Intensity Focused Ultrasound) delivers precise ultrasound energy to the deep structural layers of the skin (SMAS layer) — the same layer surgeons target in a facelift — without any incisions. This stimulates collagen production and causes gradual tightening and lifting over 2 to 3 months. HIFU is ideal for mild to moderate skin laxity on the face, jawline, neck, and brow. Results typically last 12 to 18 months.
HIFU causes a warm, tingling sensation and occasional brief sharp discomfort as energy is delivered — especially over bony areas. Most patients tolerate it well with topical anaesthetic or oral pain relief. Side effects are temporary: mild redness, swelling, or tenderness for 24 to 72 hours. Rarely, temporary numbness can occur. Serious side effects are uncommon when performed by a trained dermatologist using certified equipment.
Results from HIFU largely depends on the quality of the device used and the doctor/provider. At Reva Skin and Hair Clinic, Dr. Acharya uses Ultraformer 3 - one of the most popular and most proven machine worldwide.
Laser treatments at Reva Skin and Hair Clinic address: melasma and other pigmentation disorders, acne scars and textural irregularities, enlarged pores, sun damage and uneven skin tone, and overall skin renewal and radiance. Different laser wavelengths and modes are selected depending on the specific concern and skin type.
Results vary by indication. For acne scars and skin resurfacing, improvement is long-lasting but requires sun protection to maintain. For pigmentation, results can be permanent if triggers (UV, hormones) are controlled — without this, pigmentation can recur. A personalised maintenance plan is always discussed at your consultation to protect your investment in treatment.
You can book by calling or WhatsApp-ing us at +977 9749717175 or +977 9808751945, emailing drprakashacharya@gmail.com, or filling the contact form on the website. Consultations are available at both our Sorhakhutte and Kamalpokhari branches in Kathmandu.
Please bring: any previous dermatology prescriptions or reports, a list of current medications (including supplements and oral contraceptive pills), photographs of your skin concern if it fluctuates (e.g. acne flares), and a note of how long you have had the concern. Come with a clean face — no heavy makeup — for accurate skin assessment. Wearing a broad-spectrum SPF on your way to the clinic is always encouraged.
Yes — patients from across Nepal (and occasionally from neighbouring countries) visit the clinic. For those travelling from outside Kathmandu, we recommend coordinating your appointment in advance so we can schedule your consultation and any same-day procedures together, minimising the number of trips required. Dr. Acharya also provides online consultation to patients abroad. Contact our Whatsapp +977 9749717175 for appointments.
