Hi I prefer to shave my under arm area every few days instead of waxing.I have found that over the years my under arms have gone darker. Could you recommend a gentle under arm lightener? And what is the reason for the darkening of the underarm?

Shaving can make your underarms appear dark. Try using a mild scrub while your taking a shower to exfoliate the dark discolorations under your arms. Then apply a skin lightening cream containing hydroquinone or kojic acid to lighten the discolorations. You can also use an alpha hydroxy cream. Apha hhyroxy creams can help shed away the dark dull skin, making your skin brighter and renewed. You can look for these products at a pharmacy in the skin care aisle.
