baby neck

My baby's skin is uneven too since she has lots of rashes, and her natural skin tone is dark so it's quite obvious. My guess is new skin is formed since the old skin is damaged and will have a lighter color, plus newborn skin may change color in the first year (our PD said so). I can't guarantee it's the same case here but if baby shows any discomfort or scratching you can visit a PD for opinion.
