Amorepacific to debut anti-ageing bioflavonoid ingredient in new Laniege serum

K-beauty major Amorepacific is set to introduce a bioflavonoid extracted from camellia seeds with the launch of a new Laneige anti-ageing serum that targets three key skin ageing concerns.

The new anti-ageing ingredient, RE.D Flavonoid, are camellia flavonoids isolated from Camellia japonica seeds.

It will feature in a new Laneige serum and will target three specific skin ageing concerns – anti-wrinkle, firming, and skin radiance.

Collagen application can enhance the anti-acne effects of red and blue light irradiation

A study in China has suggested that alternating red and blue light irradiation combined with collagen dressing can improve the treatment efficacy of acne vulgaris.

The study found that red and blue light irradiation promotes the syn­thesis of adenosine triphosphate (ATP) through actinic action, increases cell metabolism, pro­motes cell proliferation, accelerates the release of growth factors, improves local blood circula­tion, and promotes local repair of fibroblasts.

Thereby the study concluded that red and blue light treatment promoted wound healing “to a certain extent”.

Yak collagen shows promise in accelerating healing process of sunburns

Non-denatured type I collagen from yak hide has been found to be an effective remedy for sunburns as it can promote the regeneration and replenishment of collagen, says a new Chinese study.

Animal collagen has been widely used in the treatment of skin wounds due to characteristics such as high biocompatibility and bioactivity.

What makes yak a unique cattle species, is that it lives primarily on plateaus with excessive UV exposure, prompting researchers to study its ability to heal sunburnt skin.

Chinese herbal bath therapy shows efficacy against atopic dermatitis in children

Chinese herbs containing anti-inflammatory, anti-allergy, itch-relieving and immunoregulating benefits can reduce symptoms and the recurrence of atopic dermatitis, without the side effects associated with conventional treatment methods.

Findings from the meta-analysis indicated that the beneficial effects experienced by the trial group were significantly greater than that of the control group.

“The Chinese medicines in the herbal bath work synergistically through multiple pathways, acting on the immune response, skin barrier function, neuroendocrine-immune system, microbial flora, and more.”

Plant-derived dyes’ effect on human hair need more research to justify large-scale production: Chinese review

There should be further exploration of how plant-derived colourants interact with human hair to justify possible large-scale production of plant-based hair dyes, say researchers in China.

The increased demand for safer, ‘greener’ and more natural hair colouring agents has resulted in the scientific community looking into on natural colourants as a replacement for synthetic hair dyes.

Based on this, researchers conducted a review on the historical applications of a variety of natural plant hair dyes. The review summarised current literature on phytochemicals and their botanical sources, colour chemistry and biological and toxicological properties.
