Yes, CO2 lasers can go wrong, leading to complications like burns, scarring, infection, and pigmentation changes (darkening or lightening), especially if used incorrectly or by inexperienced practitioners; proper pre- and post-care, including sun avoidance and antiviral medication for cold sore history, is crucial to minimize risks.
Risks and Considerations
Pigmentation Changes: Some individuals may experience changes in skin pigmentation, particularly if they have darker skin tones. Infection and Scarring: There is a small risk of infection and scarring if post-treatment care is not followed properly.
Fortunately, delayed-onset permanent hypopigmentation seen in up to 19% of cases with previous generation CO2 lasers is very uncommon. Nevertheless, fractional lasers are certainly capable of damaging the skin enough to cause excessive fibrosis and disruption of melanogenesis, the causes of hypopigmentation.
Signs of a CO2 Laser Treatment Gone Wrong Concerns include prolonged redness and unexpected scarring after treatment. A CO2 laser treatment may be problematic if you experience severe pain, persistent redness beyond typical healing time, blistering, infection signs, or unusual scarring.
Laser resurfacing can cause treated skin to become darker or lighter than it was before treatment. This is called post-inflammatory hyperpigmentation when the skin darkens and postinflammatory hypopigmentation when the skin loses color. People with brown or Black skin have a higher risk of long-term skin color changes.
The improper use of lasers can cause changes in the pigmentation of the skin. Hyperpigmentation results in pink, red, or brown spots on the face. Hypopigmentation removes the natural skin tone. Either of these conditions may be able to be rectified with further laser therapy.
Postinflammatory hyperpigmentation (PIH) is another side effect that is seen with the use of several different lasers, including CO2. This condition occurs due to hypermelanosis, which results from dermal inflammation. It is known to be the most common side effect of lasers in individuals with darker skin.
PRIMARY CAUSES OF LASER ACCIDENTS
Set up a simple test: Mark a point on your wall, rotate the level 180 degrees, and check if the laser line hits the same spot. Green laser technology provides clear, sharp lines for accurate measurement.
While the typical recommendation is three to five sessions, the ideal number varies based on your specific goals, skin condition, lifestyle habits, and other unique factors.
However, the quality of your results depends heavily on the recovery process. Protecting the treated area from sun exposure, avoiding irritants, following aftercare instructions, and allowing adequate downtime will help ensure that your skin heals properly and that you enjoy the full benefits of skin rejuvenation.
You may not be a good candidate for laser skin resurfacing if you have: Active acne. Very dark skin. Deep wrinkles.
CO2 laser resurfacing works best for deeper skin issues, such as scarring, sun damage, and extensive wrinkles. Botox is ideal for improving the appearance of existing wrinkles and preventing new ones from forming. Dermal fillers can restore plumpness/volume and reshape different areas of the face.
CO2 laser therapy is an alternative option for removing benign skin lumps, such as warts, moles, actinic keratosis, and superficial non-melanoma skin cancers. Your dermatologist may recommend this treatment if you have a skin condition that does not improve with other remedies or if cosmetic surgery is risky for you.
Before laser hair removal, you need to know it requires multiple sessions, isn't painless (more like a rubber band snap), needs shaving (not waxing) beforehand, and demands strict sun avoidance, but it's worth it for long-term smoothness, with initial hair shedding and temporary redness common after treatments. Proper prep, patience, and understanding that hormonal changes can affect results are key for success, says House of Aesthetics London and Reddit users.
It is important to remember that laser hazards exist only along the beam path. The eye and skin are two parts of the body most susceptible to a laser injury.
Yes, if not used properly, certain lasers like C02 & IPL can actually worsen melasma. It's crucial to choose the right type of laser and ensure that it's performed by a skilled professional who understands the nuances of treating melasma.
After laser treatment, inflammation is our body's natural mechanism that spearheads healing. The healing following laser treatments is part of why the laser is useful. However, there is a risk of post-inflammatory hyperpigmentation or PIH when inflammation occurs for any reason.
The treated area may heal with increased or decreased pigmentation. This is rare and occurs most often in darker skin and 2-6 weeks after treatment. Hyperpigmentation usually fades in three to six months, though rarely pigment changes can be permanent. – Excessive Swelling.
The CO2 laser is a high-energy machine that can indeed cause thermal injury. This thermal injury can result in deep burns to the skin and hypertrophic scarring.
Cosmelan, Mesopeels, and Dermamelan are excellent types of chemical peels, which can be used to treat post-laser hyperpigmentation in various areas of the body. Cosmelan is ideal for treating facial pigmentation, especially when melasma is worsened by laser treatment.
For the first 2 to 3 days after your treatment:
Apply an ice pack wrapped in a soft cloth to the treated area. Hold the ice pack on the treated area for 15 to 20 minutes. Put the ice pack on the treated area every few hours, or 1 to 5 times each day. After the first 2 to 3 days, use the ice pack as needed.
