Matthew is in a league of his own, and after 5 years as his client, I can say that with full confidence. I've had injectables, lasers and peels done with him over the years and he's been slowing down the aging process in such a natural aesthetic way. What sets him apart isn't just his skill it's his commitment to the craft. He's invested in education here and abroad, constantly learning new techniques and vetting new products so his clients always have access to the most current, thoughtful care in aesthetics. You can feel that dedication in every appointment. But beyond the expertise, Matthew genuinely cares about his clients and their results. He's not just doing a service -- he's building a relationship and a long-term vision for your face. That's rare. I'm regularly offered complimentary appointments with other injectors. I decline every time. Some expertise is worth every penny, and Matthew is at the top of that list. I hope he stays in LA forever. read more

Genuine Care & Great Results - Highly Recommend Matthew Onassis I've been seeing Matthew Onassis for laser treatments (HALO, ProFractional, and TCA Cross) to help with acne scarring, fine lines, sunspots, and overall skin texture and firmness. I'm two sessions in, with a third scheduled soon, and I'm incredibly happy with the progress so far. From the beginning, Matthew has been incredibly thorough and easy to talk to. He explained each step clearly, set realistic expectations, and made sure I felt comfortable throughout the process. That kind of thoughtful communication really stood out to me. The improvements in my skin have been noticeable--especially in texture and clarity--and I feel the quality of care I've received has been well worth the investment. I genuinely feel like I'm in good hands. If you're looking into skin treatments and want someone who's knowledgeable, attentive, and not pushy, I'd definitely recommend reaching out to Matthew. read more

I decided to head to Onassis Skin based on the reviews on Yelp. When I arrived I was greeted by Matthew in a very courteous and professional manner. As I was a new patient, he was very thorough in building a connection and understanding my medical history and what my short- and long-term skincare goals were. Unlike other experiences I've had in the past, I never felt pressured and felt like Matthew really listened! In addition to his professionalism, I showed him a cherry angioma that I couldn't get rid of! I had been to 3 other places to get this removed, and none of them were able to do it (tried and failed)! Sure enough, after Matthew explained the method for removal and aftercare treatment, it has now been 6 months and it is gone forever! He definitely has the latest and greatest technology, and is very up to date with the newest and most successful procedures. I appreciate his honesty and knowledge, and will definitely be sticking with him! Thank you Matthew! read more

*Cross Posting from Google Reviews* I can't say enough good things about Matthew Onassis and Onassis Skin. I've been struggling with weight loss for a while, and Matthew really stepped in and changed the game for me. He got me started on Mounjaro, and in just about a month, I've gone from 187 lbs to 177.9 lbs. My confidence is coming back, clothes fitting better, and genuinely feeling like myself again. Matthew is the kind of provider who actually listens. He never makes you feel rushed or dismissed. Every question I had, he took seriously. Every concern I brought up, he handled with so much care. He always makes sure I'm getting the best treatment possible, and it shows. I live in San Francisco, so I haven't gotten injections yet, but when I do, I already know I'll be going to him. He's insanely knowledgeable, has a great eye, and makes you feel calm and taken care of. I wouldn't trust anyone else! If you're looking for someone who genuinely cares, who knows what they're doing, and who is honestly the best in the business, Onassis is it!! read more

I first came to Matthew for treatment in June and loved the experience. He's knowledgeable, thorough and cares about patient wellbeing! I ended up bringing my husband in recently for clear and brilliant -- he also loved it! Highly recommend. Matthew goes above and beyond. read more

I'm really impressed with the high skill level of this injector. He fixed my uneven eyebrows, gave me a natural and smooth lift, erased my crows feet and I had zero bruising or swelling?! Amazing results. I will definitely be returning. He's also extremely knowledgeable and will give you an honest educated opinion. Very clean, friendly and easy to book. 5 stars! read more

Dr. Onassis is the only person I trust. He is a perfectionist in the best way possible, and every time I come to see him I leave more informed from the knowledge he shares and more comfortable in my own skin. Every visit is always relaxing and I leave excited about the results. He achieved the perfect subtle natural looking results I asked him for. He is a 10/10 pro and knows exactly what he is doing. read more

I cannot say enough amazing things about Dr. Matthew Onassis and his clinic in Beverly Hills. He completely transformed my face through facial balancing--and truly, my life along with it. I've never felt this confident or at peace with my appearance until I met him. From the moment I walked into his office, the experience was nothing short of top tier. He was so welcoming, the space was beautiful, and Dr. Onassis took the time to really understand my goals. He has an incredible eye and a natural approach that enhanced my features in the most refined, subtle way. I still look like myself--just the most sculpted, refreshed, and confident version. If you're considering facial balancing or anything in the aesthetics realm, this is the place. Dr. Onassis is an artist, a professional, and hands down the best in the game. I'm forever grateful. read more

I've tried a handful of aesthetic doctors in Los Angeles and Dr. Onassis is truly the best. So nice, so welcoming, actually takes the time and listens to what YOU want. He seriously cares so much! My lips have never been more even, natural and hydrated! lol I didn't even know that was a thing! My lips have lasted over a year which is crazy, at other places my filler would migrate or dissolve in about 2 months. And when I asked if I could go bigger in my lips one time he explained why that wasn't a good idea - GREEN FLAG WHEN A DOC ISNT AFRAID TO SAY NO TO YOU! Seriously the only doctor I will go to now, so so happy with him read more

AMAZING EXPERIENCE!!!! Very kind and knowledgable, had a delightful visit with Matthew, 12/10 would return! I felt comfortable and was greeted kindly when I entered, we chatted about the services I would and he was able to answer all my questions with depth and definitely knows exactly what to do for your face, would highly recommend! :) I also got the IV drip and I'm very excited to see the results, if I'm being honest I am half way through my myers cocktail and feeling pretty chipper, not sure if its that but it feels like it! read more

I've been going to Matthew for over a year now for all different treatments, procedures, picking up skincare and vitamins. He is extremely knowledgeable, talented, professional, and if you're lucky you will see his funny side. I've already recommended him to several of my best friends who are now all his patients! Thank you Matthew! We love you!! read more

I highly recommend Onassis Skin. The space is intimate and Matthew is very personable. It feels comfortable and concierge. He deeply understands the benefits of the different treatments he offers and can recommend one or put together a combination of treatments to achieve the goal you have. He's very straight forward on treatment downtime and the results to expect. I couldn't be happier or more grateful to have found Onassis Skin read more

Matthew and his team are the absolute best! Onassis Skin is where you need to be. I was struggling with dehydration all weekend and couldn't find a place that charged a reasonable price for saline. Just saline! A mutual friend of mine introduced me to Matthew and I immediately reached out to him. Less than 48 hours later, I was in his office being treated. Matthew was like a walking encyclopedia the way he answered all my questions. He even educated me on the importance of getting regular IV drips. I felt absolutely amazing after my drip and so hydrated. I highly recommend coming to Onassis Skin. Quality service and the most amazing bedside manner. I will be back! read more

Matthew was recommended to me by someone who has beautiful skin! So I went in to see him and he is so nice and patient. Today I had a level one peel and in two weeks I will have a laser treatment. When I have more time later I will go In for a level 2 peel. I've never done a peel so chickened out on the level 2 today and got the level 1 but will be back for the level 2! I am so grateful he was so kind to me since I got a little anxiety and changed my mind. He was very accommodating and I appreciate it! Can't wait to have flawless skin and to "look like my filter!" I prolonged the journey but there is just a lot going on right now. Go in to see him! He is down to earth and funny. He does everything and his clients have great skin! He doesn't gate keep he is ready to show you how to have the most fabulous skin evehhhh read more

Dr Onassis took such great care of me. Checked on me every day with detailed instructions. He really cares and does a great job !

Matthew is the absolute best! He's the only person I will ever come to for cosmetic procedures. I've been coming to him for years. He is so thorough and makes sure you're comfortable throughout the whole process. I've gotten lip injections and Botox and I can't wait for him to do my peel and lasers so that my skin is looking its absolute best! He has single handedly helped me heal my hormonal acne. Highly recommend if you're looking for natural looking results! read more

Omgggg I went in for an IV and had the best experience!! I was in a private room that had no smell to it. I can't offices that have cleaner smell or perfume or cancels. This one was white glove spotless. Then Matthew used a lower voice bc he knew I wasn't feeling well and had some light jazz to calm me down. I got a big IV which took around 45 min. He had texted me the address to the parking garage and his office so all of it was easy to find. I left feeling better and now he will be my go to for IV's! I already told my co workers about him :) read more

I definitely recommend Matthew for all your skincare/skin enhancing needs. He demonstrates precise attention to detail and provides great education and personalized recommendations without pushing you on any treatments/products. Always a great experience! read more

Just finished my second treatment of PRP & filler for my under eyes that have become hollow & dark recently. Very happy with the results and am looking forward to my future treatments. Recommend 10/10. read more

Matthew is truly gifted and talented! In my teens, I suffered from cystic acne concentrated in my t-zone and temples. The scarring has always been a big insecurity of mine. A couple months ago I visited Matthew and he immediately understood my skin type & concerns and recommended a multi-step laser approach to repairing the scarring. I did Halo laser all over my face and ProFractional lasers to my temples. After a few days, I noticed a major difference in my skin. It felt like he had taken an eraser to my biggest skin insecurities. I'm so pleased with my results. Matthew is truly the best. I sent my Mom to him, my best friend to him. And I highly recommend you go to him as well if you want to live your best skin life. read more

Matthew is my go to for Botox and skincare needs! He's incredible knowledgeable about current treatments and has a keen eye for aesthetics. I also go to Onassis skin for laser hair removal and have seen results far better than any previous laser hair removal treatment I've had. I've also done and peel and had amazing results. Matthew constantly checked in with me and helped me through the process which was great. I always recommend my friends and family to book an appointment! read more

I went in today for Jaw filler and let me just say I have never been happier. Matthew and his colleague Ben were so warm and inviting and made me feel super comfortable. This was my first time ever getting filler and they walked me through the whole process, explained the procedure to me, and really provided exactly what I wanted. I can't recommend this place enough! read more

Been coming here for the last year and a half. Matt and his staff are super friendly, professional and easy going. Matt's expertise rivals that of any top dermatologist and surgeon. (He trained under both. ) If you want honest, good results...this is your spot. read more

It's always a happy time at Onassis Skincare! I've been frequenting this office for various skincare needs. I appreciate that Nurse Matthew has a discerning eye and ensures he delivers the best for my concerns.
