Hello! What you referred to as "hypertrophic scars" is likely a type of hypertrophic scar or keloid.
Individuals with a predisposition to these thickened scars or keloids are not suitable candidates for laser treatments or unnecessary surgical interventions, as any injury can result in raised hypertrophic scars or keloids.
It is recommended to consider local steroid injections or cryotherapy for improvement.
Best wishes for your health from Dr.

Laser treatment can indeed be an effective option for smoothing out raised acne scars on your face. Raised scars, also known as hypertrophic scars or keloids, can be particularly challenging to treat, but various laser therapies have shown promising results in improving their appearance.

One of the most commonly used laser treatments for raised scars is the fractional laser. This type of laser works by creating micro-injuries in the skin, which stimulates the body's natural healing process and promotes collagen production. As new collagen forms, it can help to flatten and smooth out raised scars over time. Fractional lasers can also improve skin texture and tone, making them a versatile option for scar treatment.

Another option is the pulsed dye laser (PDL), which targets blood vessels within the scar tissue. This laser can reduce redness and improve the overall appearance of the scar. PDL is particularly effective for scars that are red or inflamed, as it helps to decrease the vascularity of the scar tissue.

However, it's important to note that while laser treatments can significantly improve the appearance of raised scars, they may not completely eliminate them. The effectiveness of the treatment can vary based on factors such as the type of scar, the individual's skin type, and the specific laser technology used. Multiple sessions may be required to achieve optimal results, and it is essential to have realistic expectations.

As with any medical procedure, there are potential risks and side effects associated with laser treatments. Common side effects include temporary redness, swelling, and discomfort in the treated area. In some cases, there may be a risk of hyperpigmentation or hypopigmentation, particularly in individuals with darker skin tones. It's crucial to discuss these risks with your dermatologist or healthcare provider before proceeding with treatment.

Before undergoing laser therapy, a thorough evaluation by a qualified dermatologist is essential. They will assess your skin type, the characteristics of your scars, and your overall health to determine the most appropriate treatment plan. In some cases, a combination of treatments, such as laser therapy alongside topical treatments or microneedling, may be recommended for enhanced results.

In summary, laser treatment can be an effective option for smoothing out raised acne scars on your face. Fractional lasers and pulsed dye lasers are among the most commonly used methods, each with its unique benefits. However, it is vital to consult with a qualified dermatologist to discuss your specific condition, treatment options, and any potential risks involved. With the right approach, you can achieve a smoother and more even skin texture over time.
