i have sort of like peach fuzz as well but its more on the upper lip. it wasnt very bad before in fact, in wasnt even that noticeable, but i started shaving it because i started using the biore moisturizer stuff and it said that it worked better on recurring hair. but now i have a really bad shadow there that looks worse than it did before. what can i do?

The shadow is caused by darker hair just under the skin. I recommend switching to epilation in that area: plucking (if it's not a lot) or waxing (to save time).

If you want a permanent option, electrolysis can be great on a small area (if the practitioner is recommended by someone done and happy). If the hair is dark and the skin light, some have found laser a good option for reducing the size and darkness of hairs, sometimes permanently.
