If you are only going to use one product on your skin, it probably should be vitamin A, otherwise known as retinol or retinoic acid.

Retinol is one of the few cosmetic ingredients with molecules small enough to actually penetrate the surface of the skin, so it actually can make a difference at a cellular level.

Regular use of a good quality retinol product will smooth and plump the skin, reduce fine lines and wrinkles, reduce pigmentation and age spots, and leave skin looking generally healthier and younger.

Retinol is found in very small amounts in many over-the-counter beauty products. However, for it to really have an effect you will need a stronger formulation, which will only be available from your doctor.

We recommend ZO retinol products, created by world-renowned dermatologist Dr Zein Obagi. Our patients have found these products produce excellent results, helping with many skin conditions.
