“I can't recommend Tiffany enough. She's incredibly skilled and has such a great eye for natural-looking results. As a former aesthetic injector myself, I have particularly high standards. I had some filler placed in my lips to help balance and WOW they are perfect.”
“I went to Glowtox as a first time lip filler and Botox client, and Isabel was my nurse for both! She was so incredibly helpful through the entire process and made me feel super comfortable as a first-timer. I'm so happy with the lip filler results and can't wait to book Isabel again. She's amazing and soooo sweet!!”
Thalia R.· Isabel, RNGoogle
“Tiffany is amazing! I had my first ever lip filler today... I have the vaso vagal nerve response so anything with needles makes me very dizzy. Tiffany was beyond understanding and had every helpful tool a girl could need... I really respect her natural approach to injections. I highly recommend Tiffany for anyone who is nervous about the process or the results.”
J S.· Tiffany, NPGoogle
“Love Glowtox & Tiff. I've had lip filler and Botox/Dysport and I'm super happy with my results and treatments. The office is extremely clean and professional. I never feel rushed, and clear pre- and post-care instructions are always provided. Highly recommend.”

Common questions
Lip filler questions, answered.
Does lip filler hurt?
We use numbing to keep you comfortable. Most patients describe it as quick pressure rather than pain.
Will it look natural?
That is the whole point. Our nursing team treats conservatively and builds gradually, so your lips look like a refreshed version of your own.
How long does lip filler last?
Most hyaluronic acid lip filler lasts 6 to 12 months depending on the product and your metabolism. We plan your maintenance at your visit.
Is there downtime?
Minimal. Some swelling or light bruising is normal for a few days. Most people return to normal activity right away.
How much does it cost?
Lip filler is priced per syringe, and we give you an exact quote at your consultation. New clients receive a $100 injectable credit toward their visit.
