One of the most common concerns patients share when they come into my St. Louis office is skin laxity—the gradual loosening and sagging of skin on the face, neck, arms, or abdomen. For many, this change is frustrating because it makes them look older than they feel, even if they’re otherwise healthy and active.

At Sheen Vein (Aesthetics and Functional Medicine), we help patients understand what causes skin laxity and what they can do to restore firmness, strength, and confidence.

What Causes Skin Laxity?

Skin laxity happens when the deeper structural proteins of the skin—collagen and elastin—break down or decline. A few common causes include:

• Aging: Collagen production naturally decreases with age.
• Sun exposure: UV rays damage collagen and elastin fibers, leading to premature sagging.
• Weight loss: Significant weight loss can leave behind loose skin.
• Hormonal changes: Estrogen and testosterone influence skin thickness and hydration; imbalances can accelerate laxity.
• Lifestyle habits: Smoking, poor diet, dehydration, and lack of sleep can all weaken skin over time.
• Genetics: Some people are more predisposed to thinning skin and sagging due to their genetic makeup.

At-Home Approaches to Improve Skin Laxity

1. Protect Against Sun Damage

Daily use of sunscreen is the most important step in preventing further collagen breakdown. Broad-spectrum SPF protects against both UVA (aging) and UVB (burning) rays.

2. Optimize Nutrition

Skin health begins from the inside out. Foods rich in vitamin C, zinc, protein, and healthy fats support collagen production and repair. Collagen peptide supplements may also improve skin elasticity for some patients.

3. Stay Hydrated

Dehydrated skin appears more saggy and wrinkled. Drinking adequate water daily and using a moisturizer with hyaluronic acid helps plump and support the skin barrier.

4. Strength Training and Muscle Tone

Building muscle mass can improve the appearance of sagging skin, particularly on the arms, abdomen, and thighs.

5. Quit Smoking

Nicotine damages blood vessels and reduces oxygen delivery to the skin, speeding up collagen loss and skin thinning.

Professional Treatments for Skin Laxity

While lifestyle and skincare matter, many patients need professional treatments to truly tighten and rejuvenate their skin. At Sheen Vein (Aesthetics and Functional Medicine), we offer a variety of options:

1. Fotona Laser Skin Tightening

Fotona’s advanced laser system stimulates collagen remodeling beneath the surface of the skin. Over a series of treatments, patients see tighter, firmer skin with improved tone and texture.

2. PRP/PRF Skin Rejuvenation

Using growth factors from your own blood, PRP and PRF stimulate collagen and elastin production naturally. This treatment is especially effective for delicate areas like under the eyes, where skin laxity is common. Learn more about our PRP/PRF services.

3. Microneedling with PRP

Microneedling creates tiny channels in the skin, prompting the body’s repair response. Adding PRP accelerates healing and enhances collagen stimulation, leading to firmer, more youthful skin.

4. Red Light Therapy with PEMF

Red light penetrates the skin to improve mitochondrial function and circulation, which supports collagen repair. When combined with PEMF, results extend to improved cellular healing and skin resilience.

5. Dermal Fillers and Injectables

For areas where skin laxity is paired with volume loss, fillers can restore structure and contour, especially in the cheeks, jawline, and temples. Neuromodulators (like Botox®) help reduce dynamic wrinkles that make laxity more noticeable.

Functional Medicine Support for Skin Health

Skin laxity is not just about aging—it often reflects what’s happening internally. That’s why we integrate functional medicine with aesthetics.

• Hormone testing: Low estrogen, progesterone, or testosterone can accelerate skin thinning and sagging.
• Nutrient panels: Identifying deficiencies in vitamin D, zinc, or amino acids that support collagen.
• Inflammation reduction: Chronic inflammation breaks down connective tissue; addressing gut health and food sensitivities may help.

By correcting these imbalances, we improve not only skin appearance but also overall vitality.

When to Consider Professional Help

If sagging skin is affecting your confidence or if at-home strategies are not enough, it may be time for an evaluation. Treatments like laser therapy, PRP, and red light therapy can make a dramatic difference in skin laxity without the need for surgery.

Final Thoughts

Skin laxity is a natural part of aging, but it doesn’t have to define how you look or feel. With a combination of lifestyle strategies, functional medicine support, and advanced aesthetic treatments, you can restore firmness and rejuvenate your skin.
