Protective effects of Paeonia suffruticosa callus extract in skin through anti-inflammation and repair UVB-induced damage.

Objective: The study investigated effects of peony callus extracts (PCE) on the protective efficacy against Ultraviolet B (UVB)-induced photoageing, using in vitro and in vivo studies. The research focused on PCE's ability to protect against inflammatory factors, DNA damage and accumulation of senescent cells, along with the evaluation of the extract's potential anti-photoageing benefits to skin.

Methods: Human keratinocyte cell line (HaCaT cells), mast cells and fibroblasts were used to evaluate the role of PCE in anti-photoageing.

A novel microcapsule composite Spherulites Peony Superior Retinol mitigates UVB-induced skin damage in vitro and in vivo.

Skin serves as our outermost barrier, protecting our bodies from various environmental damages. Increasing research has revealed that UVB is a primary factor for extrinsic aging. This study explored the role of a novel microcapsule composite Spherulites Peony Superior Retinol (SPSR) on skin damage induced by UVB.

Evaluation of the safety and efficacy of cosmetics ingredient Spherulites Paeony Superior Retinol.

Background: Microencapsulation of hydroxypinacolone retinoate (HPR) can improve its application in cosmetics.

Objective: To investigate the safety and efficacy of Spherulites Paeony Superior Retinol, a HPR microcapsule containing 5%-10% peony seed oil, 0.01%-1% epigallocatechin gallatyl glucoside (ECGG), and 0.
