Not all anti-aging skin products contain synthetic chemicals. For the most part, a couple of the most "damaging" ingredients in some products are alcohol and fragrances. Both of these can actually dry the skin and cause irritation.
If one is concerned about using products containing these ingredients, he or she could use all natural lotions. Some of the best natural products contain aloe-vera, vitamin E (natural), sea kelp extract, and avocado. Oatmeal scrubs are also natural and good as an exfoliate.
