* *** * ***** ********** **** *** ****** ***** ********* ** ********* ******* It gave very good results by reducing my pigmentation and giving my skin a fresh glow.
I completed 5 sessions, and I can clearly see that my pimple marks and pigmentation have reduced significantly. Earlier, I had also undergone chemical peel treatments, which helped clear my pimples effectively. Now my skin looks much cleaner, healthier, and the marks have reduced a lot.
I also got a few skin tags around my neck removed using the CO2 laser treatment, and the procedure was completely painless.
The doctors take a lot of time with every session and perform the treatments very carefully. They explain everything in detail and provide complete care, guidance, and advice before starting the treatment. The doctors are very professional, soft-spoken, and skilled in their treatments.
The clinic is well-maintained and maintains a high standard of care and hygiene. Some treatments truly improve your confidence, and this has been one such experience for me.
I would definitely recommend Dermazeal Clinic to anyone looking for good skin and hair treatments.
Thank you so much.

Dr. Janet is very approachable and genuinely friendly. I visited her for severe acne, which was painful and had affected my confidence significantly. I had tried multiple doctors and treatments in the past and spent a considerable amount of money, but nothing worked as effectively as Dr. Janet’s treatment.
She carefully understood my condition, explained everything clearly, and provided a treatment plan that truly made a difference. Over time, my acne improved to an extent I hadn’t experienced before.
I’m very grateful for the care I received and would highly recommend her to anyone dealing with skin concerns. I’ve already referred a couple of my friends and family members as well.
Thank you!

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.
