I visited Dermazeal clinic in HSR Layout in the month of February. I had lots of acne scars, dark circle, and wrinkles. First thing Dermazeal welcome was very warm. The reception staffs and nurses all were very professional, I met Dr. Janet for my concern, she is very professional and a nice person. She was listening all my concerns very politely and explained the reason behind my problems. Then she suggested few treatments which were worth spending. I took Q-Switched ND - Yag laser for acne marks and sun tan, Chemical Peel for undereye Dark circles and Botox for my wrinkles.
Dr. Varsha did all the treatments.
Botox made me look more younger and Q-Switched ND – Yag removed all the dark spots,
All the procedures worked very well on my skin, the only thing we have to follow post treatment medicines. This is my last session, I’m so happy to share my experience with this ****** ***** DERMAZEAL CLINIC.
Waiting time is a bit excess but Dr Janet consultation and treatment are worth the wait

I came to Dermazeal, HSR, seeking treatment for significant hyperpigmentation on my face and neck. I am thoroughly impressed with the approach taken by Dr. Janet Alexander Catelino.
From the initial consultation, Dr. Alexander was very clear and comprehensive in outlining a multi-modality treatment plan tailored to my condition. The prescribed regimen included a combination of Yag ND Laser sessions, chemical peeling, and supporting topical and oral medications. This balanced approach immediately instilled confidence that I was receiving expert care.
I have currently completed my second session (out of a planned 4-5), and I am already seeing encouraging progress. The high pigmentation has responded well to the treatments, and the results so far are very promising.
A special note must be made about the clinic staff: they are exceptionally professional, ************** and diligent in their roles, ensuring that every session is comfortable and executed flawlessly.
I highly recommend Dr. Janet Alexander Catelino and the entire team at Dermazeal for anyone seeking effective, high-quality dermatological care, particularly for complex pigmentation issues. I look forward to completing my remaining sessions, and I will update this review once the full 4-5 session procedure is complete to share the final outcome.

Dr janet is been really helpful and while I was really feeling low esteemed with my complete pimples face. I had to get rid of those. While doctor provided medicine and also suggested for chemical peel I took up without second thought and for now I'm done with peels and my face looks much better than every before.

ave been consulting Dr Janet castelino at DermaZeal for the past 1 year for my pigmentation, melasma and blemishes all over my face and which I was even getting on my chest and back as well..
Doctor gave me some ointments, moisturisers and sunscreen and asked me to apply time to time without fail and she even asked me to get a sunscreen.
I also followed the same as informed and I used to visit her regularly twice in a month and following to that she also asked me to start q-switched nd: yag laser session and I took a package consisting of 5 sessions.
Aftertaking laser treatment and medication together my active pigmentation were under control and I hardly got any breakouts....
She used to change my medication after seeing my improvements.
And once I got rid of all my pigmentation she gave me tropical creams for my marks .thank you so much for bringing my confidence

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

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.
