What Is a Chemical Peel?

A chemical peel is one of the most effective and time-tested treatments we offer at Blue Monarch Skin Studio in San Mateo. Using a carefully selected acid solution, a chemical peel exfoliates and removes the damaged outer layers of skin, stimulating the growth of newer, healthier cells underneath. The result depends on the peel type and strength, but the common thread is smoother, brighter, and more evenly toned skin.

Light (Superficial) Peels

Light peels work on the epidermis, the outermost layer of skin. They are safe, gentle, and require little to no downtime, making them popular for first-time clients or ongoing maintenance.

Common acids used: Glycolic acid, lactic acid, mandelic acid, salicylic acid, and enzyme peels.

Best for: Mild pigmentation, dullness, mild acne, skin texture improvement, hydration.

Downtime: 1-3 days of light redness or mild flaking.

Medium Peels

Medium peels penetrate beyond the epidermis into the upper dermis, triggering a more significant renewal process. They deliver more noticeable results for concerns like acne scars, deeper pigmentation, and early signs of aging.

Common acids used: TCA at moderate concentrations, Jessner solution, and higher-percentage glycolic acid.

Best for: Moderate sun damage, acne scarring, deeper hyperpigmentation, fine lines.

Downtime: 5-7 days of visible peeling.

Deep Peels

Deep peels are the most intensive option, penetrating into the mid-dermis for dramatic skin transformation. These require clinical oversight and significant preparation and recovery.

Common acids used: Phenol-based solutions and high-concentration TCA.

Best for: Deep wrinkles, severe sun damage, significant acne scarring.

Downtime: 1-2 weeks, with full healing taking several weeks.

How to Choose the Right Peel

Choosing the right peel depends on your skin type, concerns, lifestyle, and tolerance for downtime. At Blue Monarch Skin Studio in San Mateo, every new peel client receives a thorough consultation before we recommend a treatment level. For most clients new to peels, we start with a light treatment to assess skin response. For specific peel types, read our guides on glycolic acid peels and TCA peels for acne scars.

Preparing for a Chemical Peel

Two weeks before, discontinue retinoids and avoid tanning. The week before, avoid waxing or other facial treatments in the peel area. On peel day, arrive with clean skin and inform your esthetician of any medications, especially those increasing sun sensitivity.

Post-Peel Aftercare

  • Do not pick or peel flaking skin.
  • Keep skin well-moisturized with gentle, fragrance-free products.
  • Apply SPF 30+ every single morning.
  • Avoid retinoids and active acids until fully healed.
  • Stay out of direct sun for at least a week.
