Carnitine (L-Carnitine)

About L Carnitine in DIY Skin Care

Recently attention has focused on the beneficial effects of L-Carnitine on the skin. A study established that L-Carnitine prevents and alleviates deleterious skin conditions such as varicella scarring, wrinkle formation and sunburn peeling. The benefits of L-Carnitine to the skin are discussed below.

Hydrating power of L-Carnitine in cosmetic formulations

Since L-Carnitine is hygroscopic, even small amounts are able to hydrate the skin, leaving it soft, smooth and moisturized. A human panel test was carried out, in which sites on the forearms of the panelists were either untreated, treated daily with a placebo formulation, or treated daily with a formulation containing 2% L-Carnitine. Corneometer readings were then taken at each site to determine hydration levels. The hydration level of skin treated with L-Carnitine increased by 26.4%, compared to 12.5% for the skin treated with placebo. As expected, the hydration level of the untreated skin did not change significantly.

Influence of L-Carnitine on epidermal turnover rate

The ability of exfoliating .-hydroxyacids such as lactic acids to accelerate the turnover rate of skin cells is well known. Similarly, L-Carnitine, a ß-hydroxyacid exhibits excellent skin exfoliating properties, even at low levels. This exfoliating effect manifests itself as acceleration in epidermal turnover rate.

In healthy skin, the outermost cells in the horny layer are constantly being sloughed off and replaced by new cells generated in the basal layer of the epidermis. The time needed by a new generation of cells to travel from the basal to the upper horny layer is the epidermal renewal time. When the equilibrium of the skin is altered, dead cells tend to accumulate in the outer layers, the turnover rate declines and the renewal time increases.

As we age, the time required for skin renewal also increases. In young and middle aged adults the renewal time is approximately 20 days, whereas in adults over 50 the rate of turnover slows and the renewal time increases to approximately 30 days.

Removing the dead skin cells and increasing the rate of skin turnover typically results in younger and healthier-looking skin.

 In-vivo determination of turnover time, clearly shows that application of L-Carnitine does indeed accelerate skin turnover. In the trial, skin was renewed after an average of 18 days with L-Carnitine treatment and after 21 days with placebo treatment, whereas untreated skin required 23 days. This is equivalent to a 12% increase in epidermal turnover rate

L-Carnitine for oily skin

Ppromising new research shows that when applied topically, L-Carnitine, is also effective in treating oily skin. The cause of oily skin is the substance sebum, which is produced in the sebaceous glands. For those with oily skin, the overproduction of sebum gives the skin an unwanted shiny, oily appearance. The study (PDF)  aimed to identify an active substance to reduce sebum production by regulating fat metabolism in a natural way.

Carnitine exists in two forms: L-Carnitine and D-Carnitine.  Only the L-Carnitine form is desirous as the D-Carnitine form is physiologically inactive and can inhibit the uptake and functions of the natural isomer L-Carnitine. BulkActives' Carnitine is L carnitine.
