Lip Treatments

Lip filler, or just a lip flip.

Not everyone needs filler. At your consultation we'll tell you which one actually fits your lips and your goals, even if that means starting smaller.

Lip Filler

Volume and shape, built gradually.

Hyaluronic acid filler placed with an anatomy-first approach to add fullness, correct asymmetry and define the border. We build in stages so the result still looks like you.

  • Thin or naturally small lips
  • Uneven or asymmetrical shape
  • Volume lost with age
  • Dissolvable and fully reversible
Lip Flip

A subtle roll, no volume added.

A few units of tox at the upper lip border relax the muscle so the lip rolls slightly outward. It shows more of what you already have without adding any filler.

  • A gummy smile or thin upper lip
  • Ten minutes, no downtime
  • A good first step before filler
  • Results last around three months

“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.”
Mollie E.· On Tiffany, NPVerified Google

“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.

Where are you located?

Pacific Beach at 910 Grand Ave Ste 203, and Solana Beach at 115 W Plaza Street.
