BOTOX Cosmetic is the most commonly performed cosmetic procedure used to reduce or eliminate the appearance of facial wrinkles through minimally invasive injections. These injections are made from botulinum toxin A, a therapeutic muscle-relaxing agent approved by the FDA for several different uses.
Over time, permanent furrows and deep wrinkles develop in the skin as a result of aging, overuse and constant muscle contractions. These lines can make you look older, sad, angry or tired, most often developing around the eyes and mouth, as well as between the eyebrows and on the forehead. Fortunately, dermal fillers such as Juvederm Injectable Gel can erase these signs of aging to restore a younger, more refreshed appearance.
Spider veins, also known as telangiectasias, are small, thin blood vessels visible beneath the skin. They appear most commonly on the face or legs, and may looks like a series of lines, tree branches or a spider- or web-like shape, with a red or blue color. While most cases of spider veins are of purely cosmetic concern, some patients may also experience uncomfortable symptoms such as aching, burning, swelling and cramping from this condition.
Dermatologists are board certified medical physicians trained to diagnose, treat and prevent skin conditions in patients of all ages with benign and malignant disorders of the skin, mouth, external genitalia, hair and nails. We have extensive knowledge in the diagnosis and treatment of common conditions such as skin cancer, melanomas, moles, contact dermatitis, allergic and non-allergic disorders, and infectious diseases.

Dr. Liskanich is an amazing physician! Aside from being knowledgeable in his profession, he is very charismatic and cares about his patients. I had seen multiple physicians for my severe acne, none of them could help me. I was very desperate since my acne was only getting worse. Dr. Liskanich's acne treatment was very effective. After the first month my face was about 80% free from acne.

After the second month, my face was unrecognizable. My skin had never been so smooth and acne free. I absolutely recommend Dr. Liskanich and will be sending all my friends and relatives to this dermatologist. You won't get this type of treatment and attention anywhere else!

I highly recommend Dr. Stevens. She is very thorough and knowledgeable in her work and has done wonders for my skin. I don't live near her office anymore but she is well worth the drive!

I have been going to Dr. Stevens for 10+ years and she is THE BEST! I went to numerous doctors in the past to help treat my scalp condition and nobody was able to diagnose my problem. Dr. Stevens has diagnosed my issue and has been able to treat and control it. I highly recommend Dr. Stevens!

Great doctor. I hear her husband is amazing too and takes his time. Word gets around that shes good so her office is extremely busy. Wait times are long, despite an appointment. I wish she had wifi in the lobby to entertain her patients and I can do work while waiting.

I know Dr. Ronald Stevens for the last 30 years he was the only one out of 3 other Dermatologist that Dx. My children with scabies. It was a big relief after my children already had developed burrows on their elbows. It took us 10 months to get cured a living nightmare. I'm always grateful that I found him. I also went for lip fillers and had them done 3 other times with a plastic surgeon had never ever been measurements done my lips were way off!

I was what? I was very happy after my procedure So 6 weeks later I went for nasal labial fillers had them done previous with my plastic surgeon also. He said no you still have some. What you need is cheek fillers and man was he right it was a instant face lift and today 3 months later their even more Amazing! I'm staying with him definitely I'm in love with his Art!

Every one in this office is so kind I started comeing here years ago the office staff is very efficient boy do they work hard. I recently transitioned into Medicare which means unless you have a pop you have to go to a doctor that except Medicare. So off I go to Pacific dermatology in upland. WHat a disaster they ould not have been less caring sloppy work asked for certain things to be done on ba ck didn't get done I could go on about it.

I told my husband I'm going back to DR LISKANICH even if I have to pay I feel way more comfortable and safe in this office. So today I went for my appointment and sure enough the other place missed a couple of things that should have biopsied he found them right away. I hear some people say that they allways behind and they don't like to wait this is what I tell them just bring a book snack bar and some water and relax because the people that are ahead of you are getting great service and care just like you will get when you get in so give them a little slack the y are saving lives here thanks again dr Liskanich OH and shout out to gi gi the estatition you rock thanks again MARI Keen

I have had problems with acne and acne scars due to health issues and I have seen many people in the past 10 years. Whatever is out there you name it, I have tried it. I regret not coming to Dr. Liskanich and Dr. Stevens sooner. The moment I came they handled my adult break outs right away. After that, I went ahead and start working on my scars and every treatment Dr. Liskanich has recommended has improved my scars up to 70% (I know I can't go back to perfect as some are deep).

I went from covering my face with make up to a tinted moisturizer as my daily make up. The happiness and increase confidence they have given me back I can't repay them enough. I waited a little bit first visit then I get send within 5 minutes which is the norm for any doctors office or even better than others, so I don't understand the other reviews.

Couldn't even talk to a receptionist on the phone. They automatically put you on hold then forget about you. I was placed twice on hold for 15 minutes with a courtesy reminder that they still know you're waiting. So I wouldn't waste my time giving them business.

I didn't give five stars as I'm still in the healing stages. Dr. Liskanich did CO2 laser on my face; eye lids; neck; ear lobes and so far I see quite an improvement. I think this doctor is quite knowledgeable in what he is doing and would highly recommend him to others.

I am giving an extra star because Dr. Pham is great! Otherwise, one-star due to them dropping our insurance provider AFTER we scheduled our appointment and not letting us know. We found out because our insurance denied coverage for being out-of-network, but we verified they were IN network at the time of scheduling the appointment. Then, I called their office to see if they'll accept payment over the phone or online, but before I had a chance to ask anything, I was put on hold.

After 10 minutes on hold, I called back and got the recording that they are "out of the office" -- twice! -- at 2:30 in the afternoon on a Thursday, when they are supposedly open until 5:00. IF you want to have a great visit with a dermatologist, see Dr. Pham, but if you want a hassle-free billing situation, definitely go elsewhere!

As always, this office goes above and beyond for their patients. First time seeing them in their new location and it was the same great 5 star service as always. My skin continues to be in tip top health thanks to their hard work and knowledge!

This office is highly unsafe, openly disdains any efforts to maintain safe practices in the time of COVOD-19, and knowingly and consistently wastes thousands of hours of patient time each year. Patients deserve better and need to let the doctors know by demanding that the office treat them with respect. Or, the medical licensing board needs to step in and enforce patient care. Patients, and the receptionist, deserve so much better. Dr. Stephens may be a good dermatologist, but people are not sheep, and should not act or be treated like sheep.

The office practices are callous and inconsiderate of patients. I made an appointment to see Dr. Pham, another practitioner in that office. I arrived 10 minutes before my appointment. The waiting area was about 10 feet by 10 feet. There were 5 people waiting, wearing masks, but 4 were seated two feet apart at most, one standing against the wall because the other chairs had been moved to the wall, backs to the center of the room, to prevent patients from coming as close to the receptionist window as they were to each other.

All the patients were in their 60s or older. The air was stale, the room was uncomfortably warm, and 2 waiting patients were talking animatedly. I went to check in and asked about the wait. After hemming and hawing a bit the receptionist told me the wait might be "as little as an hour" as my doctor had only 2 patients in front of me in addition to the 1 in her office.

I asked her if I could reschedule at a less crowded time and she told me that I was there at the best time, as Dr. Stephens was not there that day and her patients generally had to wait at least 2 hours. The arrogance and danger of this regular protocol is shocking. If the wait is usually 2 hours, there are obviously serious problems with the way her appointments are scheduled.

If each patient has to wait 2 hours, and there are 16 patients per day that have to wait that long, that adds up to 160 hours of wasted patient time every week, 8000 hours per year, and that is only 1 doctor. Multiply that by the number of doctors in the office. The waste of patient time, when the office knows full well that both the way they schedule and the way the doctors practice causes these regular waits, is both arrogant and selfish.

Now COVID-19 has made the way these doctors practice a real danger. I am shocked that anyone in the medical profession would be so disdainful of the health and well-being, as well of the personal time, of their patients. Needless to say, I will not trust my health to such a group of doctors, and I can only hope that others will wake up to the danger and have the self-respect and courage to do what I did. I turned to the others waiting, said "This is not safe." I walked out.

De. Liskanich is horrible, immediately offered last resort to remove wart off my 5 year old daughter. Suggested scraping it off instead of any other options. When asked about local anesthetic he dismissed it. Will NEVER visit this office again. He has an attitude problem as well.

I would highly NOT recommend this doctors office. My daughter had an appointment to remove a wart and we waited over an hour and a half and we were never seen. They are extremely unorganized and rude. Especially during COVID, one would think that they would schedule less people but the lobby and the hallway was full. RIDICULOUS!

My daughter saw Dr Liskanich for her acne and we couldn't be happier. With the medication and cream she is doing much better. He took his time with her and really helped her with his words to build her self confidence. Also gave her the option of v beam treatment. We will be taking our other daughter there next week. Highly recommended!

Dr. Stevens has been my wonderful dermatologist for 20 years. Recently, a tiny, pea-sized growth on my left wrist Dr. Stevens removed, a biopsy performed, and it was the most rare of all lethal carcinoid cancers - Merkel Cell. This cancer is worse than any Melanoma and has a huge death rate - HUGE! It was early and after a massive effort by City of Hope, a fabulous plastic surgeon, pathologists at Loma Linda, and Dr. Stevens, I am cancer free!

Thank you, Dr. Stevens for saving my life - LITERALLY! Any person living in California, should absolutely see Dr. Stevens a minimum of twice a year if you want to live a long, healthy, skin-cancer free life.

This location is easy to find and there is plenty of parking available. It is surrounded by a beautiful environment and not so compacted like others. When you go inside it is a little "stuffy and cramped". There are so many chairs to sit for patients, but little space for stretching. The only amenities are magazines and air conditioning. The chairs are pretty comfortable, but I don't believe it is enoug I went here for an appointment and the recent yelp reviews were not joking.

You do wait for an hour for your assigned appointment. I do not, I say do not come here. You are met by uncaring professionals for your time and money. I have met with a male/old/glasses wearing dermatologist in the past and all he cared about is about money. I did not care enough to remember his name and his care did not do anything. I just can't believe I had to wait for an hour for an appointment? I understand if it was a walk-in, but clearly their system is wack. They have so many nurses in the back and clearly overstaffed. Trust me your money is in a better place.

Super grateful, thankful and blessed to have an opportunity to be seen by Dr Gloria Stevens, she truly invests time with you and ensures she provides the best service as possible. My wife was hospitalized for 14 days for a severe "unknown" rash at Arrowhead Regional, which they have thought to be leukocytoclastic vasculitis but also my wife had other symptoms such as severe joint and stomach pain, so they did xrays, ct scans, endoscopy, colonoscopy and assumed it could be colitis or chrons (pending biopsy results) and the end of 14 days no treatment, and simply to be released without any solid news.

The rash only became worse, and symptoms never resided. We ended up making an appointment to see Gloria Stevens which comes heavily recommended by other doctors within the San Antonio Regional Hospital, they said you must see Gloria, she's not your average dermatologist and has seen cases that your average dermatologist does not, so we trusted them, and came to see her.

My wife was seen and biopsies were performed and sent same day to USC. She is very very talented, didn't look phased by any of this and was very confident when providing my wife care. We have an appointment again this Friday as a followup and we are pushing all past medical records to Gloria for review. Very helpful staff, very talented doctor, very organized, professional, sincere and caring. Highly recommended.

Went here with my mom. We waited an hour in the waiting room just for her to go over results and then found out there were still multiple patients in front of us. We left and asked for the results to be mailed to her primary. Ridiculous wait time. No thanks.

My family has been patients of Dr. Liskanich for more than 20 years. I would not go to any other dermatologist and have recommended them to many friends over the years. While Dr. Liskanich has been our primary doctor there, we have seen Dr. Stevens and other doctors they have had on staff over the years. We have had total confidence in the quality of care and have had some serious issues properly handled to include the judgment to refer me to an excellent Mohs/plastic surgeon to remove a basal cell carcinoma on my cheek a few years ago.

I see some complaints here about the office running late for appointments. Like many great doctors we have had over the years, sometimes there is a wait to be seen. I have found that the best doctors we have had, take extra time with patients if necessary and sometimes that causes appointments to run late. I have never felt rushed by any of the doctors in the exam room and that, I think, is well worth the wait.

I had my first appointment to see Dr. Stevens early last week and contrary to some of the reviews below I had a very pleasant experience at this office from the very beginning. The receptionist was accommodating in getting my appointment scheduled for a future date that I felt was appropriate, honestly I would question the quality of any doctor if they regularly had next day appointments open.

I was politely addressed as soon as I entered the office by the staff and waited for a maximum of 20 minutes before I got to see Dr. Stevens directly. Dr. Steven's bedside manner instantly reaffirmed with me why I scheduled my appointment with her rather than a different doctor. I felt very comfortable as she practiced great empathy in educating me on my condition and all possible remedies. I had a truly 5 star experience in my visit to Dr. Stevens and would highly recommend she and Dr. Liskanich to anyone seeking cosmetic dermatology in the future.
