Efficacy testing: anti-wrinkle

Skin wrinkles

Wrinkles are common sign of ageing and occur because of various biological processes that affect the skin's structure and function. They are visible lines, creases, or folds that appear on the skin's surface.

Elastin and collagen are crucial proteins that provide support and elasticity of the skin. As we age, the production of these proteins decreases, leading to a loss of skin firmness and development of wrinkles.

Dehydration and loss of moisture are also a result of ageing. As we age, the skin's ability to retain moisture diminishes, leading to dryness and appearance of wrinkles.

Free radical damage occurs because of exposure to environmental factors such as UV radiation or pollution. These unstable molecules can damage skin cells, leading to premature aging and formation of wrinkles.

Muscle contraction due to facial expressions causes dynamic wrinkles, also known as expression lines. Over time, these repetitive movements lead to formation of lines, such as crow's feet and forehead wrinkles.

Signs of wrinkles

The signs of wrinkles can vary in severity and location, the most common are fine lines, deep furrows, marionette lines, nasolabial folds, lip lines, neck wrinkles, crow's feet, forehead lines…

They commonly develop in areas of the skin that are exposed to the sun and are subject of repeated movements due to facial expressions such as smiling, squinting, raising eyebrows…

Measurement principles and instruments

To prove anti-aging claims, we measure the following parameters using the following instruments:

Evaluation of depth and degree of wrinkles with microcamera

  • Visioscan VC 20plus (Courage + Khazaka Electronic)

  • Cortex Dino-Lite (Cortex Technologies)

  • Microcamera SoftPlus (Callegari)

Efficacy testing protocol is prepared for each product individually with close cooperation with the sponsor. Based on the claims, usage regime and efficacy expectations, we prepare a protocol that is suitable for the type of product and can confirm product efficacy. The studies can be performed over a different time period (from a few days to several weeks or months) depending on the claim and type of measurement.
