The science of skincare is making significant advancements in the time it takes for your barista to serve your daily cuppa.So what’s a busy woman like you to do? Don’t get left behind. (And don’t worry if high school science was never your forte!) Here’s our simple guide to all the ways your favourite skincare products are waging war against aging skin, and what you should look for on the ingredients label.1. The target: mitochondrial decayMitochondria are cellular power stations responsible for producing the majority of energy in each and every cell of your body. All key processes depend on mitochondria for the supply of energy. Unfortunately, mitochondria are also responsible for the majority of the oxidative damage in cells because most of the free radicals are by-products of the mitochondrial fuel cycle. Since oxidative damage and decreased energy production are hallmarks of aging, mitochondria are believed to play the key role in the aging process.Ingredients to look for: Glissandrin ((-)Schisandrin B, Schisandrin B), acetyl-L-carnitine, alpha lipoic acid, idebenone, carnosine, benfotiamine, thiamine, rhodiola.2.

To address the issue, some skincare products are incorporating ingredients that stimulate or replenish depleted hormones as a way to counteract aging.Ingredients to look for: melatonin, growth hormone, DHEA, coconut oil, metformin, kinetin.3. The target: cellular matrix depletionThe depletion of intra-cellular マトリックスエキス 効果 matrix components, and the deterioration of the matrix structure, have been recognized as a cause of wrinkles, fine lines, loss of suppleness, and other visible signs of skin aging. Stimulating the production of collagen, elastin, hyaluronic acid, and other intra-cellular matrix components has been a common approach to fighting skin aging.
