Breast milk, coconut oil-based face cream may help treat acne

Washington, Apr 17 (ANI): A face cream made from breast milk and coconut oil could cure acne, a new study claims.

A natural product found in both coconut oil and human breast milk - lauric acid - may offer treatment for acne, says a scientist.

The bioengineering graduate student from the UC San Diego Jacobs School of Engineering developed a "smart delivery system" - published in the journal ACS Nano in March - capable of delivering lauric-acid-filled nano-scale bombs directly to skin-dwelling bacteria (Propionibacterium acnes) that cause common acne.

Bioengineering graduate student Dissaya "Nu" Pornpattananangkul will present her most recent work on this experimental acne-drug-delivery system at Research Expo, the annual research conference of the UC San Diego Jacobs School of Engineering.

Ph.D. student Dissaya "Nu" Pornpattananangkul is developing a smart system of drug delivery.

Lauric-acid-based treatments could avoid these side effects, the UC San Diego researchers say.

"It's a good feeling to know that I have a chance to develop a drug that could help people with acne," said Pornpattananangkul, who performs this research in the Nanomaterials and Nanomedicine Laboratory of UC San Diego NanoEngineering professor Liangfang Zhang from the Jacobs School of Engineering.

The new smart delivery system includes gold nanoparticles attached to surfaces of lauric-acid-filled nano-bombs. The gold nanoparticles keep the nano-bombs (liposomes) from fusing together. The gold nanoparticles also help the liposomes locate acne-causing bacteria based on the skin microenvironment, including pH.

Once the nano-bombs reach the bacterial membranes, the acidic microenvironment causes the gold nanoparticles to drop off. This frees the liposomes carrying lauric acid payloads to fuse with bacterial membranes and kill the Propionibacterium acnes bacteria.

"Precisely controlled nano-scale delivery of drugs that are applied topically to the skin could significantly improve the treatment of skin bacterial infections. By delivering drugs directly to the bacteria of interest, we hope to boost antimicrobial efficacy and minimize off-target adverse effects," said Zhang. "All building blocks of the nano-bombs are either natural products or have been approved for clinical use, which means these nano-bombs are likely to be tested on humans in the near future." (ANI)
