Anti wrinkle skin creams are predominantly moisturiser-based cosmeceutical skin care products marketed with the promise of making the consumer look younger by reducing, masking or preventing signs of skin aging.

These signs are laxity (sagging), rhytids (wrinkles), and photoaging, which includes erythema (redness), dyspigmentation (brown discolorations), solar elastosis (yellowing), keratoses (abnormal growths), and poor texture.

Anti-aging creams may also focus on specific causes of skin aging, such as exposure to the sun.

Tretinoin

Although the exact mode of action of tretinoin is unknown, current evidence suggests that tretinoin decreases cohesiveness of follicular epithelial cells. Additionally, tretinoin stimulates mitotic activity and increased turnover of follicular epithelial cells. Tretinoin is better known by the brand name Retin-A.

Despite great demand, many anti-aging products and treatments have not been proven to give lasting or major positive effects. One study found that the best performing anti wrinkle skin creams reduced wrinkles by less than 10% over 12 weeks, which is not noticeable to the human eye.

However, recent studies at Manchester University showed that some ingredients have an effect. Intimia® incorporates some of these in their skin cream line such as:

Ingredients

Sleep Wrinkles

Anti-aging creams may include conventional moisturising ingredients. They also usually contain specific anti-aging ingredients, such as:

• Retinol (for instance, in the form of retinyl palmitate). In various formulations it has been shown to reduce fine lines and pores.
  

• Alpha hydroxy acids (AHAs) and beta hydroxy acids or other chemical peels. These help to dissolve the intracellular “glue” that holds dead cells together on the skin. The use of this type of product on a daily basis gradually enhances the exfoliation of the epidermis. This exposes newer skin cells and can help improve appearance. AHAs may irritate some skin, causing redness and flaking.
  

• Peptides, such as Matryxil and copper peptides.
  

• Anti-oxidants are substances that may protect cells from the damage caused by unstable molecules known as free radicals.
  

• Sunscreens provide a high level of UVA protection against the effects of UVA radiation, such as wrinkles.
  Vitamin C is supposedly one of the most effective and commonly included ingredients in wrinkle creams. It is also thought to help the healing process.
  

The effects of these ingredients depends on their concentration and mode of application. Many skin care companies recommend using a treatment programme which may combine these ingredients. For example, AHAs can make the skin more vulnerable to damage from the sun, so the increased use of sunscreens is often recommended.
