YS Creams

Our skin renewal program is the first step in restoring your skin to a healthy state. It was designed to treat photoaging, precancerous skin changes, increased pigmentation due to sun and hormones (estrogen) and acne in both men and women of all skin types and color.


The skin renewal program utilizes a vitamin A derivative (Retin A), in combination with a bleaching cream (hydroquinone), glycolic acid (an alpha hydroxy acid), Yerba Santa (a penetrating agent), and a sunscreen. Facial wash, toner and sunscreen are other important components of the program.

Latisse® is the first and only approved prescription product proven to grow eyelashes longer, thicker, and darker. Latisse is believed to lengthen the growing phase of the eyelash cycle which increases the number and percentage of hairs in that cycle. It is applied with a sterile, disposable applicator to the base of the upper eyelashes at bedtime. Most patients experience longer, thicker lashes in as little as eight weeks and see significant improvement by 12 to 16 weeks.


Maintenance therapy is required to continue this effect. Latisse is safe and ready to use.


Let our medical staff show you what Latisse is all about and how to use it. You do not need to pay for an office visit in order to get started.
