Regular exfoliation is one step to more luminous and smooth skin. It is particularly effective in conjunction with medical peels and microdermabrasion.
There is no one method for every individual, and like all effective skin care options, it is a matter of trial and error to find your best option. Your dermatologist can guide you with the decision. I have found both mechanical (rough face cloth or fine scrub) and chemical (AHA, salicylic acid) are effective.
I am not a fan of salt on the face. Sugar is popular for body scrubs. I usually recommend fine particulate scrubs on the face, or gentle enzyme peels.
It is important to inform your skin care provider about allergies and the use of retinoids like Retin-A. Always remember that exfoliation is important just before using an "active" like antioxidant or moisturizer to enhance penetration.
Use regular sun protection to prevent future damage while you are correcting the old damage from sun exposure.
