Skin rejuvenation is a broad term that encompasses treatments designed to restore your skin's youthful quality — improving texture, tone, firmness, and overall radiance. But what does that actually mean at a biological level, and how do modern treatments achieve these results?
The Science of Skin Aging
Your skin is in a constant state of renewal. Cells divide, collagen is produced and broken down, and the epidermis turns over roughly every 28 days in young skin. As we age, these processes slow. Collagen production decreases, cell turnover slows, and the cumulative effects of sun exposure, environmental stress, and natural aging become visible as fine lines, uneven tone, texture changes, and loss of firmness.
How Rejuvenation Treatments Work
Most modern rejuvenation treatments work by creating a controlled stimulus that reactivates your skin's natural healing and renewal processes. This stimulus can take several forms.
Energy-based treatments like XERF™ and LaseMD Ultra™ deliver targeted thermal energy to specific depths within the skin, triggering collagen remodeling and new collagen production. Regenerative treatments like PRF use your body's own growth factors to stimulate cellular renewal. Chemical and mechanical treatments remove damaged surface cells to accelerate turnover and reveal healthier skin beneath.
Choosing the Right Approach
The right rejuvenation treatment depends on your specific concerns, skin type, and goals. At PH Med, Dr. Bui evaluates skin health through the lens of the PH Protocol — assessing contrast, resolution, density, and recoil to determine which modalities will address the root causes of your concerns, not just the surface symptoms.
