NeoGen vs CO2 Laser | Worthing

Two routes to skin regeneration — one ablative, one not. A doctor explains the difference and who each suits.

By Dr Amber Halliday, MRCGP MBBS BSc (Hons) — GP & Aesthetics Doctor | Blue Bird Aesthetics, Worthing | Updated 2026

CO₂ laser is the most aggressive resurfacing tool in aesthetic medicine. NeoGen Plasma is the most significant regenerative one. They are not the same kind of treatment, and confusing them leads to patients either expecting too much from NeoGen or tolerating more downtime than they need to from laser. Here is the clear, clinical comparison.

TL;DR — Quick Summary

Short on time? Here’s what matters:

✓ CO₂ laser ablates — it vaporises columns of skin. NeoGen regenerates — no open wounds.

✓ CO₂ suits deep wrinkles and significant acne scarring on lighter skin tones.

✓ NeoGen suits eyelids, crepey texture, early laxity, and a broader range of skin tones.

✓ CO₂ has higher PIH risk in darker Fitzpatrick types. NeoGen is significantly safer.

✓ CO₂ is not safely used around the eyes. NeoGen is one of the best eyelid treatments available.

✓ I offer NeoGen in Worthing. I do not offer CO₂ laser — this comparison helps you decide which to seek.

	NeoGen Plasma	CO₂ Laser
Mechanism	Nitrogen plasma — regenerative	Light energy vaporises skin columns — ablative
Open wounds	No	Yes — requires wound care
Downtime	3–7 days bronze/peeling	7–14 days raw skin, crusting
Pain	Topical anaesthetic sufficient	Often nerve blocks or sedation
Eyelids	Yes — a key indication	High risk — rarely used
Pigmented skin tones	Lower PIH risk; broader range	Higher PIH risk in darker types
Depth of effect	Mid-to-deep dermis, regenerative	Deep ablation with collagen remodelling
Best for	Laxity, crepiness, eyelids, quality	Severe wrinkles, deep scarring

Which Should You Choose?

Choose NeoGen if…

You want eyelid treatment, have some pigmentation in your skin, want a predictable recovery with no open wounds, or your main concern is crepey texture, early laxity or overall skin quality.

Consider CO₂ laser if…

You have severe, deep wrinkles or significant acne scarring on lighter skin, and are prepared for a more intensive recovery. This requires a specialist laser clinic — not something I offer at Blue Bird Aesthetics.

Most of my West Sussex patients who come asking about CO₂ laser are, once when we talk through their actual goals, better suited to NeoGen. The downtime is shorter, the eyelids can be treated, and the result is regenerative rather than ablative.

Quick Questions

Is NeoGen as effective as CO₂ laser?

For the concerns NeoGen is designed for — eyelids, crepey texture, early laxity — yes. For deep wrinkles or significant acne scarring, CO₂ may deliver more dramatic results, but with substantially greater downtime and risk.

Which is safer for darker skin tones?

NeoGen carries significantly lower post-inflammatory hyperpigmentation risk and is suitable for a broader Fitzpatrick range. CO₂ laser requires careful assessment and is higher risk on darker tones.

Can NeoGen treat the eyelids?

Yes — it is one of NeoGen’s strongest indications. CO₂ laser is not safely used around the eyes.

How long does NeoGen last vs CO₂?

Both can produce results lasting 1–2 years with appropriate aftercare. NeoGen results typically develop over 3–6 months; CO₂ results may appear faster but involve a longer recovery.

Do you offer CO₂ laser?

I do not. I offer NeoGen Plasma, which I believe is the right tool for the majority of the regenerative concerns my patients present with. Where CO₂ is the better answer, I will say so and direct you appropriately.
