At IADermatology on Harley Street, London, we specialise in advanced dermatological treatments to help you achieve radiant, youthful skin. One of our popular options is the DEXA CO₂ Laser CoolPeel®, an innovative fractional CO₂ laser designed for scarring and rejuvenation with minimal downtime. Whether you’re dealing with acne scars or seeking overall skin tightening, this treatment could be the solution you’ve been searching for in London.
What is DEXA CO₂ Laser CoolPeel®?
The DEXA CO₂ Laser CoolPeel® is an advanced fractional CO₂ laser that resurfaces the skin in a precise and controlled way. Unlike traditional CO₂ lasers, it delivers short bursts of energy at very low heat. This allows effective skin rejuvenation with minimal downtime and a lower risk of side effects.
What Does It Treat?
The treatment is designed to improve skin texture and promote collagen production. It may be recommended for:
- Acne scars and other types of scarring
- Fine lines and wrinkles
- Sun damage and pigmentation
- Enlarged pores
- Overall skin rejuvenation and tightening
How Does It Work?
- The laser creates thousands of tiny micro-injuries in the skin’s surface.
- This stimulates the body’s natural healing response and triggers new collagen and elastin production.
- As the skin heals, it becomes smoother, firmer, and more even in tone.
- Because the treatment delivers energy in short pulses with minimal heat, it is more comfortable than traditional CO₂ resurfacing and requires less downtime.
What to Expect During and After Treatment
Most patients describe a warm, prickling sensation during treatment. A topical anaesthetic cream is usually applied beforehand to make the procedure more comfortable.
The treatment usually lasts 15–30 minutes, depending on the area being treated. After treatment, the skin may look red, similar to mild sunburn, for 1–2 days. Mild dryness, tightness, or rough texture can occur as the skin heals.
Some patients experience light peeling or flaking for a few days. Makeup can usually be worn after 24 hours, unless advised otherwise. Full results develop gradually over several weeks as new collagen is produced.
Treatment Plan and Aftercare
For best results, a course of 3–4 treatments spaced 4–6 weeks apart is usually recommended.
Some patients notice improvement after a single session, especially for skin texture and radiance.
- Avoid direct sun exposure and wear a broad-spectrum SPF 30–50 daily.
- Avoid saunas, hot showers, and vigorous exercise for 24–48 hours.
- Use a gentle cleanser and hydrating moisturiser until redness subsides.
- Do not pick, scratch, or exfoliate the skin while healing.
Risks and Suitability
DEXA CO₂ CoolPeel® is considered safe when performed by trained professionals. Possible temporary side effects include redness and mild swelling, skin dryness or flaking, and sensitivity to sunlight. Rare side effects include prolonged redness, infection, or pigmentation changes. Most skin types can be treated, but it may not be suitable if you are pregnant, breastfeeding, have active infections, or certain skin conditions.If you’re in London and looking for expert skin rejuvenation, book a consultation at IADermatology on Harley Street today.
What To Expect with Hair Shedding
- In most cases, shedding slows and stops on its own once the trigger has resolved.
- Hair density usually returns to normal within 6–9 months, though regrowth may initially appear finer.
- If the stressor remains (e.g., ongoing illness, chronic stress), excessive shedding can persist.
Self-Care Tips
- Seek support from groups like Alopecia UK (www.alopecia.org.uk) to address emotional challenges.
- Protect your scalp with sunscreen or hats to prevent sunburn on thinning areas.
- Use volumising shampoos without sulfates and avoid harsh styling products.
- Eat a nutrient-rich diet with adequate protein, iron, and vitamins to support hair health.
