Hello, don't worry. This is normal. It takes two months for the skin to fully recover before you can use it again. During this period, please pay attention to sun protection. Care suggestions during recovery To help your skin recover better, I suggest you go to the pharmacy and buy a growth factor gel or spray (external type). Growth factors can effectively promote skin repair and cell regeneration, which will be very helpful for your current skin condition. Diet and lifestyle habits Avoid spicy food: Please be sure to avoid eating spicy and irritating foods, which will irritate the skin and are not conducive to recovery. Avoid touching water: In the next few days, please try to avoid getting the treatment area wet to avoid infection or affecting repair. Avoid sun exposure: Please strictly protect yourself from the sun, and be sure to take physical sun protection measures (such as wearing a hat or holding an umbrella) when going out, and avoid direct sunlight on the treatment area. Ultraviolet rays can cause secondary damage to damaged skin. Special reminder When you are caring, the high energy of the instrument may cause a little irritation to your skin. Please follow the above suggestions and take good care of your skin, and your skin will recover soon. The energy setting is lower next time you use it. If you have any discomfort or questions during the recovery process, please feel free to contact me. I will continue to pay attention to your recovery. 

This laser cannot be used to treat spider veins or varicose veins, and can also be used for pigmentation. 

This product is designed for facial pigmentation and skin problems, where the skin is often thinner and more sensitive. The underarm and groin areas have different skin characteristics - the skin is more delicate, darker, and has more moisture and friction, which can increase the risk of irritation, burning, or uneven results when using a laser device. For safety reasons, we do not recommend using this pen in the underarm or groin areas 

Level 1 is the lowest, for removing freckles. Use it close to the skin. 

Yes, the device is suitable for most skin types. However, for very dark skin or certain skin conditions, we recommend consulting a dermatologist beforehand. 

Initial changes in the skin's appearance can be visible after just 2–4 weeks of regular use, especially with superficial pigmentation spots. 

Yes. Avoid direct sunlight for at least 24 hours and then apply a soothing serum or moisturizer. Sunscreen is always important. 

Yes, the device can also be used on the hands, arms, décolleté, or back – anywhere where pigmentation spots or discoloration are present. 

The laser generates ultrashort light pulses in the picosecond range that specifically break down melanin pigments without damaging the surrounding tissue. This gently breaks down spots. 

Start with the lowest level (level 1, frequency 1–3) and increase according to skin tolerance. Sensitive areas such as the face require a lower intensity than, for example, the arms.
