What causes brown spots on face?

Knowing what causes brown spots on face will help you choose a home remedy to remove brown face spots.

When considering what causes brown spots on face, you should take into consideration not only sun damage, which is often regarded as the most common cause, but also other factors.

Hyperpigmentation - Those Ugly Brown Spots On Skin!

More specifically Melasma or Lentigos

The brown spots we get on our skin happen from an irregular distribution of melanin. Either this can result in melasma, which is an uneven production of melanocytes causing light brown spots; or in lentigos (age spots) which are an uneven accumulation of melanocytes in the epidermis resulting in brown spots.

The melanocyte cells are located in the basal cell skin layer. These cells control the making of melanin, which gives each person their coloring. The rate of melanin production differs between each person being greater in dark skinned individuals.

Outside factors also affect the production of melanin, which may cause brown spots:

Sun exposure
Certain medications & chemicals
Hormones - pregnancy, menopause, birth control pills
Underlying health problems - nervous disorders
Acne

Melasma produces irregular, pale brown blotches that usually appear on the nose, cheeks, forehead, and upper chest. On darker skin, the blotches show up lighter than the surrounding skin. Melasma is common during pregnancy, menopause and in woman taking oral contraceptives. Sun exposure will make the brown spots worse.

Lentigos, also known as age or liver spots, are flat, light reddish-brown spots that appear on the face, throat, chest, back of hands, upper back and shoulders. Lentigos typically show up on skin, which is repeatedly exposed to sunlight. The ultraviolet sunlight causes overstimulation of the melanocyte cells in the skin. The cells clump together and show up as age spots.

Lentigos spots can vary in size from small to a couple of inches in width. They happen more often on light-skinned people and can start to be noticeable as early as the age of 30.

Even though both of these melanin-produced spots are harmless, they are unattractive to most people. So what gets rid of them?

Over the counter products that can be used to erase brown spots on skin are:

Bleaching (depigmenting) products which include-
Hydroquinone (use only on fair to light skin tones - possibly irritating)
Kojic Acid (an alternative for darker skin tones)
Azelaic Acid
Arbutin
Ellagic Acid
Retinoids (Retinoic Acid)
Vitamin C (Ascorbic Acid)
Alpha Hydroxy Acids

Bleaching products work by inhibiting the production of the enzyme tyrosinase, which in turn reduces melanin. Over time, the brown spots will fade. Bleaching products will not lighten skin beyond its' own natural color, so do not worry about going to light.

Retinoids, Vitamin C, and Alpha Hydroxy Acids can slowly fade brown spots on their own. However, they are best used in conjunction with bleaching products since they will boost the overall effectiveness of the treatment.

Always use adequate sun protection when using any of these ingredients. Your skin will be extra sensitive to the sun. In addition, hydroquinone will be rendered useless if you do not use sunscreen.

Options that are available through a skin care professional are:

Laser Treatments (less damaging to skin)
Chemical Face Peels
Freezing the area with liquid nitrogen (may cause white spots)
