One should always try to achieve one's constitutive skin colour as how much hard one tries a person with dusky complexion cannot become fairer by applying creams. Do not apply creams containing hydro quinine, steroids and tretinoin
just to achieve a fairer skin tone as in long run it will harm your skin irreversibly. Just to have a good skin tone, use a good sunscreen with SPF more than 40 in between 10 am to 4 pm and repeat it every three to four hours if out in sun. One can use mild skin creams containing Kojic acid
, arbutin , vitamin c, vitamin b3 and vitamin b5 on daily basis to improve one's skin tone. Also few sessions of chemical peels
can be taken to exfoliate the skin and improve the skin tone. Similarly mesotherapy with vitamin c and glutathione
can improve the skin colour to certain extent. However, as a doctor I would always promote a skin regime to have a healthy glowing even toned skin rather than striving for a fairer skin.Take care.
