Hello there, Thank you for sharing your concern — I completely understand how stressful this must feel. What you’re describing sounds like a superficial burn or pigmentation change that can sometimes happen when the laser interacts with dark pigments, such as black eyeliner. Unfortunately, many home-use devices aren’t able to distinguish between skin and surface pigments, so when the light energy hits a dark line (like eyeliner), it can cause a mild burn or temporary discoloration along that path. The good news is that in most cases, these marks do fade with time. It may take several weeks to a few months, depending on your skin type and how deep the pigment change is. The key right now is gentle care and avoiding anything that could irritate or inflame the area further. Here’s what you can do: Keep the area moisturized with a soothing, fragrance-free product like aloe vera gel, Aquaphor, or a gentle healing ointment. Avoid sun exposure — even small amounts of UV light can darken healing skin. Use a broad-spectrum sunscreen daily if the area is exposed. Do not pick, scrub, or exfoliate the affected area; let it heal naturally. If the area becomes darker (post-inflammatory hyperpigmentation), lightening creams containing ingredients like niacinamide, azelaic acid, or licorice root extract can help once the skin is fully healed. If you ever notice blistering, scabbing, or increased redness, it’s best to let it heal first before using any active treatments. Most importantly, avoid using eyeliner, pen, or any dark marking tools in the future when doing laser sessions — the pigment absorbs too much heat and can cause these kinds of marks. In most cases, this type of pigmentation fades completely over time, so try not to worry too much — your skin has a remarkable ability to repair itself.
