302 Treatment Plans
Solar Keratoses


The occurrence of solar keratosis is marked by persistent red scaly lesions, crusty, discolored lesions or pink, subsurface blemishes with a diameter greater than 4 mm.

Melanoma, Squamous Cell Carcinoma (SCC) and Basal Cell Carcinoma (BCC) are the main groups of skin cancer. These last two are rarely fatal (1300 worldwide per year) and melanoma is now understood to have very little, if anything, to with sunlight or UV exposure as it usually occurs where sunlight exposure is not an issue.

There is no epidemic of skin cancer, but there is a lot of publicity and noise about it and many people are paying extraordinary high costs in medical procedures for what is essentially an esthetic problem, not a life threatening or even health threatening problem.

You can clear the appearance of solar keratosis quite often with 302. Before going into that, please note the following conventional medical  treatments for solar keratosis:

Surgical Excision
Most common and least cosmetically acceptable - tissue destruction - over 50%.

Moh's Micrographic Surgery
second most common, not painful but not cosmetically acceptable - some tissue destruction - over 20%.

Curretage and Electrodessicaton (CE)
Cosmetically poor results, with tissue destruction.

Carbon Dioxide Laser and Fluorouracil (Effudex)
Painful & cosmetically poor results - tissue destruction.

Treat with Fluorouracil (Effudex) Alone
Painful and cosmetically poor results - tissue destruction.

Treat with Cryosurgery
Painful and cosmetically poor results - tissue destruction.

Treat with Methyl-5-Aminolevulinate* and Photo Dynamic Therapy (Laser) (MAL/PDT)
Painful, but cosmetically better - some tissue destruction (*also called "ALA").

Imiquimod (Aldara)
An immune system modulator - used in the treatment of venereal warts, herpes - appears to have a corrective role in SCC and AK - no tissue destruction, but high irritation and sensitization and some serious systemic problems often occur.

Results for these treatments indicate MAL/PDT is probably better in the long run cosmetically and in lowest rate of reoccurrence, with Imiquimod (Aldara) a relatively new arrival (2000) in treatment regimes.

For organ transplant patients, use of low dose retinoids (acitretin) in limiting SCC may be a lifelong requirement, IF that therapy is chosen. Discontinuing retinoids tends to increase significantly the incidence of SCC's, as compared to never using them at all. This is especially true if an organ transplant patient is involved, less so in the general population.

Interleukin-2 Cream
$300/tube - useful in advanced cases.


302 has demonstrated excellent visible reduction in solar keratoses.
Reoccurrence rates for solar keratosis is high. Generally if you get one, you'll get another.

For directly treating a spot

You may use 302 Serum or 302 Drops during weekdays, once per day.

Cleanse with either the Face & Body Bar or any 302 lotion cleanser.

During the weekend, apply A-Boost. You may divide up the application periods of A-Boost and 302 Serum or 302 Drops as you wish, of course.
