Not every skin cancer treatment has to involve surgery.

At RFSA Dermatology, we offer Superficial Radiation Therapy (SRT) — a non-invasive treatment option for certain basal and squamous cell skin cancers. Available at our Castle Hills and Floresville locations!

✨ No cutting
✨ No stitches
✨ No downtime
✨ No surgical scarring

SRT is ideal for patients who want a gentle, effective alternative to surgery while still achieving excellent cure rates.

If you or someone you love has been diagnosed with skin cancer, ask us if SRT is right for you.
Your skin deserves options.

Happy DYSPORT Week!!

A few reminders to ensure the SMOOTHEST week😉:

-Patients that get treated with Dysport this week and REDEEM their aspire points, will automatically receive DOUBLE the points! (For example: Patient has 400 points ($40) in their account and they redeem this week for a treatment it will automatically turn into 800 points ($80) off.)

-You can combine the double points with the $50 off dysport code! You will need to sign up/sign in to the QR/Link 1 day prior to treatment so it’s loaded into their account and ready to go.

-If you are not due for treatment/cannot come in this week, we will allow you to prepay to lock in those awesome savings!
