Skin aging is influenced by several factors, including genetics, environmental exposure, hormonal changes, and metabolic processes. In humans, structual and functional changes attributable to aging and more visibly evident in the skin than in any other organ.
Intrinsic (internal factors) aging, or your natural aging process, begins appearing in your mid-20's:
Dimethicone is a non-greasy occlusive silicone based polymer that is a man-made synthetic molecule made up of repeating units called monomers. It also has been shown time and time again to be non-comedogenic, yet it provides a significant amount of emollience and coverage to the skin, without adding any heaviness.
As we age our cycle of cell production slows down to about 45-60 days in our 40's and 50's and further slow down to 60-90 days in our 50's and 60's. Retinol is a vitamin A derivative that has been used for anti-aging and acne clients for years. Retinol stimulates the metabolism of skin cells and encourages collagen production. Retinol is much gentler when absorbed within the skin and it’s converted into tretinoin (the acid form of vitamin A, also known as retinoic acid).
Sebaceous hyperplasia is the term used for enlarged sebaceous glands seen on the forehead or cheeks of the middle-aged and elderly leading to an ongoing problem with over-productive oil glands. They appear to be somewhat indented in the middle. This indented centre is characteristic of sebaceous hyperplasia. It has nothing to do with milia or an old spot.
Perhaps you have an acne problem or maybe you just break out from time to time. Regardless, if you want to get rid of acne, you need to be careful of makeup that can cause acne cosmetica and worsen existing acne. When you go to the cosmetics counter seeking to buy makeup, moisturizer, or anything to put on your face, look at the label. If the words “hypoallergenic” or “non-comedogenic” make you feel confident that the product is good and safe for your skin, then you may very well have been duped.
Acne Vernata or contact acne, is acne related to exposure to certain substances that sometimes results in irritation, inflammation, acne flares and even allergic reactions. Not all of these reactions affect all people, or even all people who have acne. However, it is important to remember that there is a potential for contact related forms of inflammation or comedogenicity that might lead to acne flares. ~Dr. Mark Lees, Clearing Concepts
