Excessive Amounts of Grease Stuck in Pores

For the past year or so my skin has layers of this yellowish/green colored grease on my arms. It is forming layers onto my skin and it appears as if water just slides on it. My pores are totally clogged. I don't know what this may be or what has caused it. Is it possible excessive use of skin lotions can cause this? I have never heard of anyone having such a problem so I am hoping somebody here can help me. Thanks

Hi,
This could be sebaceous hyperplasia.Sebaceous hyperplasia is a common, benign condition of sebaceous glands in adults of middle age or older. Lesions can be single or multiple and manifest as yellowish, soft, small papules.
Sebaceous glands are found throughout the skin except on the palms and soles. They exist as a component of the pilosebaceous unit.
The largest sebaceous glands and the greatest number of sebaceous glands are found on the face, chest, back, and the upper outer arms.
Although more commonly found in the older population, premature or familial cases have been reported in which younger individuals are affected with multiple lesions, suggesting a genetic predisposition. In these cases of premature familial sebaceous hyperplasia, extensive sebaceous hyperplasia appears at puberty and tends to progress with age.
Sebaceous hyperplasia is completely benign and does not require treatment.Oral isotretinoin has proven effective in clearing some lesions after 2-6 weeks of treatment, but lesions often recur upon discontinuation of therapy.

This is the closest explanation I can offer, however it would be best for you to get it examined by a dermatologist to come to a definitive conclusion.
