I walked in without an appointment and was seen within 20 minutes. The team was so welcoming and genuinely listened to what I was looking for. My Botox results are perfect — natural and exactly what I asked for. This is my place now.
Finally found a medspa that doesn't make me feel rushed or upsold. I came in for a chemical peel and the results are incredible — my skin tone has evened out so much. The team explained every step and aftercare was thorough. Can't recommend enough.
Been coming here for microneedling for 6 months and the improvement in my skin texture is unreal. My acne scars are genuinely fading. The price is fair, the team is knowledgeable, and they remember you when you come back. Lilly Beauty is the best kept secret in the East Bay.
