Cell-communicating ingredients use receptor

sites or cellular pathways to interact with skin

cells to signal them to function optimally.

Retinoids (including retinol), which are

derivatives of Vitamin A, are the best known.

They act as antioxidants and neutralise the

free radicals that result from exposure to ultraviolet

light. In addition, they increase cellular

turnover, stimulate a thickening of the epidermis

and promote the removal of excess pigment.

Retinol is a Vitamin A (retinoic acid)

derivative that is an effective and widely used

topical anti-ageing solution. It has been shown

to reduce many visible signs of skin ageing,

especially fine lines and wrinkles, encouraging

better cell turnover in the upper layers and

normalising skin turnover.

In the form of stabilised retinol (retinol

molecular), it enables surface hyper-pigmented

cells to be sloughed off evenly, in addition

to reversing the damaging effects of UV

light on the skin cells, which result in hyperpigmentation.

Retinoids are also responsible

for tyrosinase inhibition, reducing clumping

of melanin and reducing melanosome size to

further improve pigmented spots.

Medical research has also documented that

the use of retinol on the skin can create new

collagen deposition, greater proliferation of new

blood vessels and capillary formation. Dramatic

improvements have also been observed with

regard to skin smoothness, evening of skin tones

and overall skin rejuvenation. Retinol also plays

a role in conditioning the skin prior to many

cosmetic procedures such as facial surgery, laser

resurfacing and chemical peels.

It has been shown

Varying forms of

Vitamin A

It’s well known skin rejuvenation can be

achieved by applying Vitamin A to the skin;

but sometimes the various types of Vitamin A

on the market may make it confusing when

selecting which type to use on the skin. There

are a number of related molecules with Vitamin

A activity and these are classed under the family

name of retinoids.

Prescription retinoids include tretinoin (trans

retinoic acid); the over-the-counter retinoid is

retinol. Both convert to retinoic acid in the skin.

Trans retinoic acid is the most irritant form of

Vitamin A.

It’s no secret that a common side effect after

starting topical Vitamin A treatment is temporary

redness, irritation and flakiness; most users will

need to build up a tolerance to retinoids over

several weeks. Retinol skincare has fewer side

effects than retinoic acid prescription products

due to lower biological activity, among other

factors. It also goes without saying that stabilised

high-concentration retinol formulations will be
