Photosensitive products, hydration, and overuse check
Potential Causes
- Photosensitive or acid-based skincare was used before treatment.
- The session was too long or the device was too close.
- Skin was not hydrated enough.
- Skin metabolism may temporarily bring underlying melanin to the surface.
- Sun protection was not used after treatment.
What You Can Do
- Stop photosensitive products before use
Avoid acids, retinoids, whitening products, and other photosensitive ingredients before using the device. - Use basic hydrating skincare
Keep your skin well hydrated before and after treatment. - Check time and distance
Maintain a distance of 10–30 cm and do not exceed 30 minutes per session. - Use sun protection
Avoid direct sun exposure after treatment. If you go outside, use SPF 30+ sunscreen or physical sun protection. - Give your skin time
If dullness is related to temporary dryness or skin metabolism, it may improve gradually with gentle care and proper use.
Details
Temporary darkening or dullness may be related to photosensitive skincare ingredients, overuse, insufficient hydration, or sun exposure. If your skin becomes noticeably darker, irritated, or uncomfortable, pause use.
