Cost Type:

Description:

Cost per professional session; at-home devices are cheaper but carry higher risks.

Summary

Microneedling creates controlled micro-injuries in the skin to trigger a natural wound-healing response. This process stimulates the production of new collagen and elastin, key structural proteins that decline with age. From a healthspan perspective, this improves the integrity, thickness, and resilience of the skin, which is the body's largest organ and primary environmental barrier.

Purpose

Stimulates collagen and elastin to improve skin health and integrity.

Card Summary

A procedure using fine needles to create micro-injuries, stimulating collagen and elastin production to improve skin texture, firmness, and barrier function.

Impact

Score:

2.5

Justification:

Primarily an aesthetic intervention with limited evidence for systemic healthspan benefits.

Evidence

Grade:

D

Score:

2

Justification:

Strong evidence for cosmetic skin benefits, but speculative for systemic healthspan impact.

Safety

Score:

3.5

Justification:

Generally safe with a professional, but risk of infection or scarring exists.

Flags

• Risk of infection, scarring, or hyperpigmentation is elevated with improper technique or at-home devices.
• Contraindicated for individuals with active skin infections, keloid tendencies, or certain skin conditions.
• Avoid use on areas with active acne, rosacea, or eczema.
• Significantly increases absorption of topical agents; use caution with active ingredients post-procedure.

Verdict

Effective for skin appearance; unproven for systemic healthspan or longevity.

Typical Protocol

• Professional sessions are typically spaced 4-6 weeks apart to allow for collagen remodeling.
• An initial series of 3-6 treatments is common, followed by periodic maintenance sessions.
• Needle depth is adjusted based on treatment goals, ranging from 0.25mm to 2.5mm.
