New research has, for the first time, discovered hemoglobin in the uppermost layer of human skin, and found that it helps protect against damage. The findings provide important insights into skin diseases such as aging and cancer.

Researchers have created a cream containing a souped-up, synthetic version of the free-radical-removing melanin we produce naturally to protect skin from sun damage and accelerate the healing of sunburn and chemical burns.

The skin ulcers that diabetics often develop on their feet are slow to heal, sometimes to the point that they become infected and require foot amputation. A magnetic gel could keep that from happening, as it triples the healing speed of such wounds.

For the first time, scientists have combined six primary skin cell types with hydrogels to ‘print’ a thick, multilayered skin that, when transplanted, successfully integrated with surrounding tissue to heal wounds more rapidly and with less scarring.

While it's important for dermatologists to know how itchy a person's skin is, patients' self-assessments are quite subjective. A new wearable sensor could help, by objectively measuring the frequency and intensity of its user's scratching sessions.

Researchers have analyzed available topical and systemic treatments for eczema and identified the ones that are most effective, presenting a full range of treatment options for this common chronic skin condition.

For the estimated 800 million people worldwide with acne, a successful new treatment would have a profound impact on quality of life. Scientists hope their new treatment method, using a drug that's unique in human medicine, will be the 'magic bullet.'

A novel microneedle patch may bring new hope to people who struggle to keep their acne under control. Instead of utilizing antibiotics, the device releases nanoparticles that kill acne-causing bacteria when triggered by exposure to ultrasound.

Got a rash or spot to check out? Take a photo! Google Lens can now save you from wading through hundreds of images of skin conditions, letting you search for your own much more easily and delivering results for diagnosis and recommended treatment.

MIT scientists have developed a new wearable patch that can deliver drugs through the skin more efficiently and painlessly. The device uses pulses of ultrasound to pry open the skin, which could improve topical medications or even tattoos.

The squid’s color-changing abilities have fascinated scientists for decades. Now, researchers have created a new squid-inspired artificial skin that can withstand extreme cold and kill microbes, opening the door to a range of potential uses.

For studies on insect-borne diseases, many a human has sacrificed an arm in a tank full of mosquitos. Now, a new artificial skin filled with real blood might spare humans the itchy bites, while providing a greater insight into mosquito behavior.
