Who you'll see
Three dermatologists.
One standard.
All three of our doctors are board-certified by the Philippine Dermatological Society — the only dermatology specialty society recognized by the Philippine Medical Association. They trained here, they practice here, and they understand Filipino skin.
Medical Director
Dr. Liana Marasigan
Laser & Surgical Dermatology
Dr. Marasigan founded Dilag in 2014 after a decade in academic dermatology at the Philippine General Hospital. She built the clinic around a conviction she still holds: that laser and energy-based treatments, done properly and conservatively, can change skin in ways that topical treatments simply cannot.
She personally performs every fractional CO₂ resurfacing, every laser hair removal consult, and every surgical excision at the clinic. She does not delegate procedures with real risk. Her patients range from teenagers with severe scarring to executives in their sixties addressing decades of sun damage — a particular concern for patients who grew up in the Philippine sun without modern sunscreen.
She is known among patients for being direct. She will tell you when a treatment is not worth it, when a cheaper option will work as well, and when the only real solution is the expensive one. She does not believe in upselling.

Aesthetic Dermatology
Dr. Cora Villanueva
Cosmetic & Aesthetic Dermatology
Dr. Villanueva joined Dilag in 2017, bringing with her a sub-specialty interest in aesthetic dermatology and a strong opinion about what aesthetic medicine should — and should not — do. Her approach is best summarized in her own words: "I want people to look like themselves on a good day. Not like a different person."
She performs all botulinum toxin and dermal filler procedures at the clinic, as well as thread lifts, PRP microneedling, and chemical peels. She is certified by the International Society of Dermatology and Aesthetic Medicine (ISDAM) and trains younger dermatologists in injection technique.
Patients tend to find her warm but honest. She will decline to perform a procedure if she believes it will look wrong on the patient's face — even if the patient is willing to pay. She has, on more than one occasion, talked a patient out of filler they didn't need and into a skincare routine they did.

Medical Dermatology
Dr. Tomas Alcantara
Medical & Pediatric Dermatology
Dr. Alcantara is the doctor patients see when something on their skin doesn't make sense. A persistent rash that three creams haven't fixed. A mole that's changed shape. A child whose eczema won't settle. He is the clinic's diagnostician, and his patience with difficult cases is well known among both patients and colleagues.
He leads our acne program and sees all pediatric dermatology patients. He trained partly at the Asian Skin Center in Singapore, which informs his particular interest in how tropical climates and Filipino skin interact — a perspective most international dermatology textbooks miss.
He is also the doctor most likely to suggest doing nothing. Many skin concerns, he'll explain, resolve on their own if given time and a gentle routine. He'd rather you wait a month than start a treatment you don't need. Patients who've been to clinics that pushed aggressive treatments tend to find this refreshing.

The Philippine Dermatological Society
What "board-certified" actually means.
In the Philippines, anyone with a medical degree can call themselves a "dermatologist." The PDS is the only specialty society recognized by the PMA. Certification requires a three-year dermatology residency, written and oral exams, and ongoing education. Our doctors hold it. Ask yours if they do.
