What is your advice to women who have uneven skin tone?
The best skin is the one you were born with.
If you have fair skin, sun tanning and tanning booths are extremely dangerous for your skin.
For darker skin, your skin protects you against the dangerous Ultraviolet Radiation so don’t try and change your skin colour. For pigmentation, see a dermatologist to advise you on the best treatment and monitor side effects like irritation.
Use a broad spectrum sunscreen that protects against both UVB and UVA. Don’t use products recommended by friends, family or pharmacist. These may not be the correct products for your skin problem.
