These things are very normal and don’t need to be “fixed”
100% normal.
But this shows that if so many people are experiencing this hyperpigmentation, that means it is NORMAL. We can’t all be “dirty.” We just have melanin.
1) temporary
2) infeffective because the melanin runs deep into the dermis
3) expensive because of maintenance
4) detrimental to skin health
increased hyperpigmentation
hypopigmentation
dermatitis
exogenous chronosis
sun burns
photo toxicity (the lemons)
and some of these are irreversible.
