If the matter comes to get rid of skin issues I would highly recommend Dr Janet Alexander *** *** ***** **** *** ***** ***** ********* ***** **** **** ******** *** *** Visited Dr Janet for my face black pigmentation and lots of uneven skin tone for which I was very much worried to go outside for any gatherings. Dr Janet adviced me to take few sessions of chemical peeling and after few sessions I could see the difference in my skin then she even suggested me to go for the laser treatment for face which was Q-Switched Nd YAG laser and magically that laser was painless and worked on my face really well.. My marks were getting lighter day by day and then I also stopped using the medicines and only thought of using that laser and it even worked without medications also I got my confidence back. Within few sessions of laser my friends and family used to see the eventual difference in my face and gave many good compliments as well. Now I can go anywhere without any hesitation and I recommend Dr Janet to my closed ones also I really thank to the doctor and dermazeal staff to make this happen and looking further to start with my hair removal sessions as well and even more excited to share my experience about my laser hair removal process.

Dr. Janet is extremely approachable and friendly. I visited her for a severe acne condition—my face was covered with painful, infected breakouts, and it had really affected my confidence. I had already tried multiple doctors and treatments
in the past, spending a significant amount of money, but nothing worked as effectively as Dr. Janet’s treatment.
She understood my concerns, explained the process clearly, and guided me with the right treatment plan. The results have been truly impressive, and my skin has improved to a great extent.
I would highly recommend her for any skin-related concerns, and I’ve already referred a couple of my friends to her.
Thank you, Doctor, for helping me regain clear skin and confidenc

Dr. Janet Alexander Castelino barely examined me and didn’t take a closer look at my skin. The consultation felt rushed, lasting only about a minute* *** *** ********** **** ********* ********* ******* **** ***********

I’m pleased to share my experience at DermaZeal Skin and Hair Clinic. It is an excellent place to seek treatment, with highly skilled and professional doctors. I visited for concerns related to acne, open pores, and hair fall. The doctor explained everything clearly and recommended chemical peels along with intense pulsed light therapy. A few blood tests were also advised, which revealed certain deficiencies, and appropriate medications were prescribed.
Additionally, I was advised to undergo PRP therapy consisting of six sessions, which I began the same day. Despite a busy schedule, the doctor was extremely friendly, attentive, and patient in addressing all my questions. She personally performed my procedures, and I am very satisfied with the care I received.
I’m now seeing noticeable improvement in my hair growth and overall results. I would highly recommend this clinic to anyone dealing with skin or hair concerns.

I had an outstanding experience with Dr. Janet Castelino. From the moment I walked into DermaZeal, the staff was warm and professional. Dr Janet is very attentive and she took the time to listen to my concerns, explained everything clearly and made me feel completely comfortable with the entire visit.
What really stood out was that she didn’t just focus on treating my acne but got to the root cause of it. After noticing some signs that might be related to hormonal issues, she recommended I see an endocrinologist.
If you are looking for a dermatologist who genuinely cares, pays attention to detail and takes a holistic approach, I cannot recommend Dr. Janet enough! She truly is a caring *** ************* **************

Today I visited this dermazeal clinic was really impressed with the experience.
The staff at reception were warm and got me checked in quickly without any hassle.
My dermatologist listened carefully, explained my skin condition clearly, and didn’t rush the consultation.
The clinic itself was spotless, modern, and felt very professional.
I went in for persistent acne and got a treatment plan that actually made sense for my skin type.
They also did a full skin check and explained what to watch for, which I appreciated.
The procedure room was well-equipped and I felt safe and comfortable throughout.
I tried one of their cosmetic services too — a chemical peel .
Overall, professional service, genuine care, and noticeable results.
I’d definitely recommend this clinic to anyone looking for skin care.
