Firstly before I get to the amazing Nicole I have to give a big shout out to Max! From my initial call to the intake to paying he was knowledgeable he set everything up for me seamlessly he was incredibly professional and also made me aware of ALL the services and products offered but not on a salesy pushy way. Just making me aware of everything they offer! It was informative and a few things peaked my interest! Now let’s get to Nicole. She is so unbelievably educated and knowledgeable about injectables! She assessed my needs addressed concerns and made recommendations based on my issues. She made sure I was comfortable and her technique was flawless. New patient !

I visited Beauty Within for the first time and was a little hesitant at first since I’m used to going to med spas in New York City. A friend recommended Beauty Within in Boynton Beach, Florida, and I’m so glad I went. I had a laser treatment called UltraClear, and Nicole, the physician assistant, met with me before the procedure. She is incredibly knowledgeable about lasers, injectables, and overall skin care—I was very impressed and felt completely at ease in her hands. The entire staff is made up of such lovely individuals. Everyone is welcoming, knowledgeable, and genuinely helpful. It was a great experience from start to finish, and I would highly recommend this med spa.

I have to give a huge shoutout to Max — he is seriously amazing! From the moment I walked in, he took so much time to sit with me, explain everything in detail, and walk me through how to get the absolute most out of my points and all the discounts available through the products I’m already using. No rush, no pressure — just genuine help that made me feel like he actually cared about my results and my wallet. Then Nicole jumped in for the consult, and wow, she was incredible too. She patiently went over all my options for laser and Dysport, answered every single question, and took the time to analyze my skin for the best treatments. Never once made me feel like I was being pushed into anything. It was such a refreshing, no-sales-pitch vibe — just honest advice and expertise. Highly recommend!

Every time we visit friends and family in Boynton Beach and Delray Beach, it’s a perfect time for a little touch up (Botox, sun block, and a few treatments). Then we look even better when returning from our trip!

Nicole is the most educated and professional clinician to deal with Botox and or fillers. She has a great eye and no one there is pushy or aggressive.
