These burns may not only damage the upper layer of skin but can also affect deeper tissues, potentially leading to scarring that can be permanent. Additionally, improper laser use can disrupt normal skin pigmentation, causing areas of hyperpigmentation (darkening) or hypopigmentation (lightening), which can be distressing for clients and may require extensive treatment to correct.

Hair regrowth can occur due to hair cycles, loss of sensation could suggest nerve involvement but is less common, and mild irritation may be a normal side effect rather than an indication of improper technique. Therefore, the more critical and widely recognized risks comprise burns, scarring, and pigmentation
