The products are most suitable for the 50+ skin.  I would like to recommend the following steps, in this order:

Cleanser, soapfree cleanser, wash 2 x per day and rinse well.

Advanced Anti-Ageing Cell Repair Serum, which uniquely contains all 3 Polipeptides which penetrate and renew the skin.  Also apply a fingertip over the facial area and neckand leave this on.

The Moisturiser with SPF30, twice per day which provides day/night moisturiser as well as sun protection.

Evaluate the skin with these steps first and one can then add more suggestions when you are ready.
