What is CO2 laser

CO2 laser (carbon dioxide) is a type of ablative laser that acts on superficial and deep layers of the skin.

It:

  • removes affected skin layers
  • stimulates collagen production
  • promotes tissue regeneration

What it is recommended for

CO2 laser is effective for:

  • moderate and deep wrinkles
  • post-acne scars
  • pigmentation spots
  • dilated pores
  • skin laxity
  • uneven skin texture

How it works

The laser creates micro-columns of energy in the skin, which:

  • destroy affected tissue
  • stimulate regeneration
  • increase collagen production

The skin gradually repairs itself, becoming firmer and smoother.

How the procedure proceeds

The procedure takes between 30 and 60 minutes.

Steps:

  1. Skin cleansing
  2. Application of anesthetic cream
  3. CO2 laser treatment
  4. Application of soothing product

You may feel a sensation of heat or slight burning, both normal after treatment.

Recovery and results

Recovery is more intense compared to other lasers.

After the procedure:

  • redness and edema (2–5 days)
  • peeling (5–7 days)
  • sensitive skin

Results:

  • visible after 1–2 weeks
  • continuous improvements over months
  • long-lasting effects

Instructions before the procedure

For safety:

2–4 weeks before:

  • avoid sun exposure

  • avoid retinol and acids

Instructions after CO2 laser

Following them is essential:

In the first days:

  • apply soothing and repair creams
  • avoid touching the skin
  • completely avoid the sun

In the following weeks:

  • use SPF 50 daily
  • avoid irritating products
  • avoid skin exfoliation

Reactions after the procedure

It is normal to experience:

  • intense redness
  • burning sensation
  • peeling
  • sensitivity

These are part of the healing process.

The procedure is not recommended:

  • during pregnancy
  • during active skin infections
  • on tanned skin
  • in certain dermatological conditions

  • effective for scars and wrinkles
  • long-term rejuvenation effect

  • longer recovery period
  • requires strict adherence to instructions
  • may require social downtime for a few days

A single injection for cholesterol — from dreams to first human results

A Phase 1 trial published in the New England Journal of Medicine (November 2025) brings remarkable results: a single infusion of CTX310, a CRISPR-Cas9 therapy developed by Cleveland Clinic and CRISPR Therapeutics, reduced LDL cholesterol by up to 49% and triglycerides by up to 55% in patients with refractory dyslipidemia — without serious adverse events. The mechanism is unique: instead of blocking a protein or interfering with its mRNA, CTX310 permanently edits the ANGPTL3 gene in hepatic cells, mimicking a natural mutation associated with reduced cardiovascular risk throughout life. The therapy is currently in Phase 1b clinical stage, with updates expected in the second half of 2026. It is not approved and does not replace current treatments. Read the full article for clinical context, comparison with statins and PCSK9 inhibitors, and what these data mean for patients.
