How effective are topical creams in reaching deeper skin tissues?
Over the counter topical creams are generally designed to be used on the surface of the skin and may not penetrate very deeply. While some creams may be able to penetrate several layers of skin, they are unlikely to reach the deepest tissues of the skin, such as the dermis.
There are a few types of topical creams that may be able to penetrate the skin to the dermis level, which is the deeper layer of the skin. These include:
Retinoids: Retinoids are a class of vitamin A derivatives that are used in many anti-aging and acne-fighting creams. They are known to increase collagen production, improve skin texture and tone, and reduce the appearance of fine lines and wrinkles. Retinoids are small enough to penetrate the outermost layer of the skin and can reach the dermis.
Peptides: Peptides are short chains of amino acids that can stimulate collagen production and improve skin elasticity. Some types of peptides, such as copper peptides, have been shown to penetrate the skin to the dermis level and promote collagen synthesis.
Vitamin C: Vitamin C is an antioxidant that can help to brighten the skin, reduce the appearance of dark spots, and stimulate collagen production. Vitamin C is also small enough to penetrate the skin and reach the dermis.
Hyaluronic acid: Hyaluronic acid is a naturally occurring substance in the body that can hold up to 1000 times its weight in water. It is used in many skincare products to hydrate and plump the skin, and some forms of hyaluronic acid may be able to penetrate the skin to the dermis level.
The effectiveness of a cream in penetrating the skin to the dermis level depends on the specific formulation, concentration of active ingredients, and individual factors such as skin type and condition. Most over the counter creams. unlike the prescribed ones by dermatologists, are low in concentration and safe for use on the outer layer of skin but not strong enough to reach the dermis.
