Results showed a statistically significant decrease in skin pigmentation and redness from the baseline over the 12 weeks and a 20% improvement in skin hydration and maintenance of skin barrier function. The results confirmed that the nature-based, broad-spectrum sunscreen was effective in improving the health of photodamaged skin without causing the signs of irritation typically observed with retinol products, the company said.
“This is the first time we’ve seen a bakuchiol-containing formula demonstrate a decrease in erythema,” adds Raja Sivamani, MD, a board-certified dermatologist at Integrative Skin Science and Research and UC Davis, in California. “With this groundbreaking research, patients don’t have to compromise and choose between more even skin tone, the retinol-alternative benefits of bakuchiol, and an effective mineral sun protection.”
In another study, 39 female participants with moderate acne-induced, post-inflammatory hyperpigmentation evaluated the effectiveness of a nature-based topical treatment containing Glycyrrhiza glabra (licorice root), Curcuma longa (turmeric root), and Terminalia chebula in reducing the appearance of PIH associated with acne.
Results showed a statistically significant improvement from baseline in skin brightness, smoothness, tone evenness, and overall skin condition, a reduction in melanin scores and corresponding pigmentation, and a 15% improvement in skin hydration and maintenance of skin barrier function, which confirmed that treatment with the nature-based topical cream was clinically safe and effective in improving the appearance of acne-induced PIH, the company said.

“Hyperpigmentation disorders, including post-inflammatory hyperpigmentation and solar lentigines, are increasingly common conditions affecting most skin types and can have a significant impact on patient quality of life,” said Zoe D. Draelos, MD, a board-certified dermatologist. “In this research, the investigator, subject, and objective assessments all concurred to show an improvement in skin brightness with the formula, which incorporates three botanical tyrosinase inhibitors. Additionally, skin condition improved overall, including on the metrics of smoothness, evenness, pigmentation, and hydration.”
