Skin ages from the inside out. As we get older, the body produces less collagen and elastin, the proteins that keep skin firm, smooth, and resilient, and cellular turnover slows. The result is the familiar loss of firmness, texture, and glow. Regenerative aesthetics is an approach built on that understanding, focused on restoring the skin’s own structure rather than simply masking surface changes.

This approach is guided by Dr. James Petros, MD, founder of NexGen Health and a physician board certified in Regenerative Medicine, Anti-Aging Medicine, Functional Medicine, Physical Medicine, and Interventional Pain Management. A Tulane University School of Medicine graduate trained at Stanford, Dr. Petros founded the practice in 2021 to deliver personalized, science-driven care in a luxurious environment, bringing a regenerative lens to aesthetics.

What Changes in Aging Skin

Skin change is gradual, and recognizing what is happening helps clarify which treatments actually address the cause.

• Loss of Firmness: declining collagen leaves skin looser and less supported.
• Fine Lines and Wrinkles: reduced elasticity allows creases to form and deepen.
• Uneven Texture: slower cell turnover leaves skin rough or dull.
• Loss of Glow: diminished circulation and renewal reduce radiance.
• Enlarged Pores and Laxity: weakening structure changes the skin’s surface.
• Slower Healing: skin recovers more slowly from blemishes and irritation.

Why Skin Loses Its Foundation

The visible signs of aging skin trace back to declining collagen and elastin, slower cellular renewal, reduced circulation, sun and environmental damage, and hormonal changes. Because the changes come from within, treatments that stimulate the skin’s own repair tend to produce the most natural, lasting improvement.

Frequently Asked Questions About Regenerative Aesthetics

What makes aesthetics regenerative?

Regenerative treatments stimulate your own collagen and cellular renewal, improving skin from within rather than only masking the surface.

Why does skin lose firmness with age?

Collagen and elastin decline over time, and cellular turnover slows, which loosens and dulls the skin.

Are results natural-looking?

Because improvement comes from real tissue renewal, results tend to build gradually and look natural rather than overdone.

How soon are results visible?

Collagen builds over weeks and months, so improvement is gradual and continues after treatment.

Is there downtime?

Many regenerative treatments involve little downtime, though some cause brief redness or sensitivity.

Who is a good candidate?

Anyone wanting to improve firmness, texture, or tone can benefit, and a consultation confirms the best approach.
