We lose around 1% of our skin's collagen from the age of 25, which is when the first signs of ageing (and fine lines) begin to appear.
The latest science has shown that fine lines don't first appear in the epidermis (the top layer of skin) as initially thought, but rather in the dermis.
Creams and serums are unable to penetrate this far making diet and nutrition critical when it comes to a holistic beauty regime.
