A Cure for Sunburn Pain and Itchy Skin

Scientists have isolated the chemical process that causes that painful, itchy feeling after a bout of sunburn.

In a study published in August in the Proceedings of the National Academy of Sciences (PNAS), researchers said they had identified a molecule, TRPV4, which seems to be the root cause of sunburn-related pain.

In moderation, ultraviolet B (UVB)  works to form Vitamin D, which has various health benefits like improved mood and stronger bones. However, UVB over-exposure activates TRPV4, which then sets in motion a chain reaction that causes an inflow of calcium ions and another molecule, endothelin, which is known to be responsible for the itching and pain of sunburn.

When researchers blocked TRPV4 with a topical solution, the itching vanished.

Although more research is needed to examine TRPV4’s side-effects, the scientists concluded that the process shows promise as a treatment for the itching associated with eczema and psoriasis.

Why Professional Laser Hair Removal is Better than At-Home Treatments

The popularity of laser hair removal has increased so much over the past two decades that hair removal devices are now available for home use. But are they as good?

Buying laser hair removal devices for home-use may appear to be money well-spent, however are they as effective as salon treatments? Professional laser treatments that use intense pulse light (IPL) or alexandrite laser treatments, such as Candela GentleLASE series and the Palomar IPL, work by using light energy to heat up the hair follicles on the skin. Once enough heat is produced, the hair follicle is destroyed, preventing re-growth of the hair. Hair growth occurs in cycles, which is why multiple cycles of laser hair removal are needed. The Candela GentleLASE and IPL are suitable for fair to darker skin tones and both cool the skin using the Zimmer Cryo 6 cooling device to ensure a comfortable client experience.

There are few USFDA (U.S. Food and Drug Administration) IPL devices approved for home use in the U.S. market. These devices use a similar technology to the professional devices, but the light bulbs are generally smaller and lighter. Treatment commonly involves up to two to three times as many treatments as the salon options, and regrowth is more frequent. At home laser hair removal treatments are also not approved or safe to be used on certain areas, such as the face. These devices may also be more painful as they do not have cooling attachments.

Laseraid’s competitive pricing options allows clinics to rent laser machines for an average return of over 300%, with the option to buy the rental at any time. This pricing includes warranty, accessories, delivery, installation and training. Generally, the main barrier to professional laser hair removal has been the price. The affordable pricing strategy at Laseraid allows clinics to understand and test the market and make decisions that best suit their business needs.
