Thank you for the additional information. Yes, I received the pictures OK, but it takes some time to type a complete answer.
Although it is impossible to make a definite diagnosis over the internet, the appearance on the pictures is more of seborrheic keratoses than multiple moles. It is also true that seborrheic keratoses are more common to arise and get worse as a person ages. Although moles can occur at any age, the vast majority of moles have developed during youth and early adulthood. And although seborrheic keratoses also can occur at any age, they are much more common in middle age and later.
From the perspective of treatment, the first issue is that neither moles or seborrheic keratoses require treatment. If a particular lesion is changing quickly to raise concern about possible cancer, then a biopsy should be performed. But the vast majority do not require treatment.
If considered unsightly, it will usually not be sufficient to try to cleanse the skin, therefore it is not surprising that vigorous scrubbing has not been effective. If it is desired that the lesions be removed, it is possible to perform simple destructive techniques, such as freezing or burning them off (with electricity or acid), although it is frequently impractical to treat all of the lesions in someone with many of these lesions. If you wish to try this to treat some of the more unsightly lesions, there is a form of freezing that is available over the counter (marketed for warts) that can be tried as well as various acids (such as glycolic acid), but a doctor may be necessary if you desire treating more of the lesions.
