In case you are the type who has given up on wearing those strappy and sleeveless tops due to the darkness of your armpits, then do not despair, help is here. There are some medical as well as homemade remedies that will have you showing of those armpits with confidence.
Home based remedies:
You can go with bleaching agents that are natural. These sort of things occur due to antiseptic, acidic and antibacterial qualities that some fruits and vegetables have.
You can use:
Potatoes: Slice a potato thinly and the rub this is the darkened area. Or you can grate and extract the juice to apply in the darkened armpit area allowing it to dry for about 10 minutes before rinsing.
Cucumber: This also works pretty much as the potato slices do. Or for more effect make a paste out of lemon juice, turmeric and cucumber juice which can be applied to the affected area before being washed off 30 minutes later.
Lemon: The rubbing of a thick slice of lemon on this area will not only lighten skin but also remove dead skin. Wash once you are done and also apply moisturizer if required.
Mix together some turmeric, honey, plain yogurt along with lemon juice; apply this mix and wash off after 10 minutes.
Egg oil: You can also apply egg oil to this area over night for the omega 3 in the egg oil to generate new skin cells to make the skin lighter and smoother. Wash off in the morning with a gentle soap.
Apply moisture: You also need to keep this area moisturized by applying something like aloe Vera etc. twice a day to ensure that the dark armpits are treated right.
Exfoliate: Another thing to consider as a remedy for dark pits is to ensure that the dead cells in this area are removed by exfoliating this area.
This can be done by:
Sugar: A mix of three tablespoons of olive oil with brown sugar can be applied to damp skin for a moment or two when you are bathing at least twice weekly for good effect.
Baking soda: A paste of soda and water can be used to scrub under the arms and even dry powder can be dusted to give a lighter look. A mix of milk, rose water and baking soda can be apply to the area and washed off with tepid water for lightening the armpits.
Orange peel: Dried and powdered orange peel mixed with milk and rose water can be used as a scrub for about 15 minutes before being rinsed off with cold water.
Pumice stone: Use the pumice stone to gently remove dead skin from the underarm area. The stone needs to be dampened before being used.
Try something liquid: This can be found right in your cupboard or refrigerator.
Milk: The fatty acids and vitamins in milk is good to lighten the skin. Use some flour, two tablespoons of milk and one teaspoon curd to make a paste. This needs to be applied and left for a quarter of an hour before rinsing with cold water. You will find skin softer and lighter.
Vinegar: A germ free and lighter look as well as skin that smells sweeter can be attained by apply a rice flour and vinegar mix to the armpits after showering, leaving on for 15 minutes and then washing it off with tepid water.
Coconut oil: The lightening effect comes from the vitamin e and this means you need to use this daily. Massage the oil for about quarter of an hour and then wash it off with tepid water and soap.
Apply a pack for whitening: Make a pack with gram flour, lemon juice, yogurt and turmeric. Apply and let it be there for half an hour before washing with tepid water.
Wax instead of shaving: The darkness of the underarm skin could be due to thickening of the hair in armpit due to shaving.
Stop using deodorizers: The inflammation of skin due to the chemicals in deodorants can also darken the underarm skin.
Talk to the doctor: Sometimes home remedies may not help if you have a condition called acanthosis nigricans that leaves dark markings in the area. This condition could be due to a glandular problem or due to obesity also found in people with diabetes and commonly in people of African descent. This problem could also happen due to growth hormone therapy, pituitary gland disorders, Addison’s disease, use of oral contraceptives and hypothyroidism.
Doing things like changing your diet if it is diabetes related, or stopping oral contraceptives could help if these are the root of the problem.
You could get a prescription of alpha hydroxyacids, Retin A 20% and salicylic acids but these are only of limited use. The use of hydroquinone is something that is done for lightening the skin and you can buy these with prescriptions for higher concentration and over the counter for lesser concentration. Always buy products that are tested and those that can be trusted. So do read the labels and do some research before buying anything.
Some cautions: In case you do not have hyperhidrosis, then it is normal to have the skin darken when the layer of skin is really thin. It is not something that you need to concern yourself about and do not be swayed by what you see on screen where women have the benefit of photoshopping and special effects.
Doing things like too much exfoliation or bleaching is not good for you in the long run and can result in scarring. You could suffer from infection of the follicles, sweat glands, pores etc.
