I'm posting this question because I'm stressed by the increasing number of freckles I have, even though I'm careful about my skin care. I understand that genetics and sun exposure are the most common causes of freckles, but I'm concerned that they've become darker and more widespread lately.
Besides simply not applying sunscreen thoroughly, are there other causes of freckles I'm overlooking? I'm also wondering if hormonal changes or lifestyle factors could also contribute to freckles. I need to know the exact cause so I can avoid recurrence even after laser treatment. I'm considering the procedure, but if you have experience with it, could you please advise if it's effective and if my skin becomes more sensitive?
