Skin Rejuvenation Q & A

What is skin rejuvenation?

Skin rejuvenation is a collective term for a variety of treatments and procedures that improve the condition and appearance of your skin. Skin rejuvenation reduces the appearance of:

  • Fine lines and wrinkles
  • Scarring
  • Hyperpigmentation and discoloration
  • Loose or sagging skin


Dr. Aguirre offers skin rejuvenation treatments for your face and your body. For example, you may want to have your chest or hands treated as well as your face, as these areas also have thin, delicate skin that easily shows signs of aging.


What are the available skin rejuvenation treatments?

Dr. Aguirre provides a comprehensive range of skin rejuvenation treatments. You have a detailed consultation with her to discuss your skin concerns, so she can understand your needs and recommend the best procedure or procedures to improve your skin.

Botox® and Xeomin®

Botox and Xeomin are injectable cosmetic treatments that have been approved by the FDA since 2002. They temporarily reduce the appearance of fine lines and wrinkles on the forehead and around the eyes by relaxing the muscles under your skin. Dr. Aguirre uses her advanced knowledge of facial musculature to create a personalized treatment plan to smooth, lift, and relax areas of the face affected by overuse of facial muscles.

Dermal fillers

Dermal fillers are another injectable treatment. They’re made of clear gels that replace volume loss in your cheeks, forehead, lips, and lower face as you get older and your body loses youthful fullness and produces less collagen.


Kybella is a unique injectable cosmetic treatment that reduces the appearance of a double chin. When injected into the submental fat under your chin, Kybella breaks down unwanted fat cells so your body can remove them.

Laser therapy

Dr. Aguirre offers a variety of laser treatments to rejuvenate the appearance of your skin. Generally, lasers stimulate your body’s natural healing response, which floods your skin with oxygen and nutrients, triggering new cell growth.

Chemical peels

Dr. Aguirre provides chemical peels in several strengths to exfoliate your skin at varying depths. A chemical peel causes the top layers of your skin to dry and peel away to reveal the fresh, unblemished skin underneath.

Microneedling with Platelet-Rich Plasma (PRP)

Dr. Aguirre uses a microneedling device to create hundreds of thousands of tiny openings in the skin surface, which stimulates collagen production and evens out skin tone. She combines this treatment with the application of platelet-rich plasma (PRP). PRP is created by drawing the patient’s own blood and spinning it down to isolate their own intensely concentrated growth factors.

This PRP can be applied over freshly micro-needled skin to intensify the collagen production and speed healing. It can also be injected directly into the patient’s soft tissue to stimulate deeper cell stimulation and rebuild the patient’s tissues. The PRP can be combined with soft tissue fillers to extend the life of the filler.  

Thread lift

Dr. Aguirre offers thread lift procedures, which are less invasive than surgical facelifts. She uses thin, medical-grade dissolving thread to pull your skin tight and lift sagging areas of the face and neck.


Dr. Aguirre also recommends cosmeceuticals — cosmetics that have medical properties. These products improve the appearance of your skin by both treating skin conditions and providing cosmetic coverage.


How should I take care of my skin after skin rejuvenation?

Dr. Aguirre gives you specific post-procedure care instructions for your skin. However, she encourages everyone to wear sunscreen every day as the UV rays in sunlight trigger changes in your skin that cause premature aging.
