What levels of the Dry Skin Index initiate dry-skin formation?

Written by DW Layton. Posted in Dry skin, DSI Sense, Skin aging.

A fundamental issue impacting our personal skin care is the inability to sense the magnitude of drying stresses on skin. This really inhibits the timely and effective use of skin moisturizers and/or humidifier. The Dry Skin Index (DSI) measures these stresses, which are conveniently monitored using Dermidia’s DSI Sense + smartphone app. But what levels of the Dry Skin Index might trigger dry-skin formation?

The Dry Skin Index is broken down into five stress categories ranging from very low to very high. Previously we identified the optimum relative humidity associated hydrated skin, but not the DSI levels at which people should begin to hydrate skin. Fortunately, data derived from a study by Jin et al. (2021) allows us to identity key threshold levels.

Consider moisturizers with ceramides for aging skin

Written by DW Layton. Posted in Skin aging, Skin Care, Skin Science.

Healthy, hydrated skin does not show signs of dryness such as dry spots or skin flakes. Skin hydration depends on the barrier function of the skin’s outer layer (stratum corneum). Lipids (fats) in this outer layer help control the loss of water from the skin. Ceramides are a key component of skin lipids. They are also used as an active ingredient in various moisturizing lotions and creams.

Treat dry skin to reduce proinflammatory cytokines contributing to age-related diseases

Keeping your skin hydrated as you age is necessary to maintain your skin’s barrier function and inhibit the formation of dry skin. Research now indicates that a collateral benefit of hydrating skin care is a reduction in proinflammatory cytokines circulating in blood. These agents in blood plasma have been associated with inflammaging, which is low level, subclinical inflammation prevalent in aging populations.

Your skin is aging–here’s what you can do

Written by DW Layton. Posted in Skin aging, Skin Science.

Aging skin is accompanied by biochemical changes that occur in the outer layer of your skin (i.e., the stratum corneum, or SC). These changes degrade the skin’s barrier function as well as its ability to retain water. Consequently, you’re more apt to experience dry skin in response to indoor skin stressors—moderated by both the weather and building properties of your residence.
