Science
Mechanism of Action
This extract, abundant in compounds like flavonoids, tannins, and paeoniflorin, functions as a potent antioxidant by neutralizing free radicals and mitigating oxidative stress, thus protecting against premature aging and UV-induced lipid peroxidation. Its anti-inflammatory action is achieved through inhibiting the release of nitric oxide (NO) and other inflammatory factors, reducing reactive oxygen species (ROS) levels, and deactivating key inflammatory signaling pathways such as MAPK and NF-κB. For skin brightening, it inhibits tyrosinase, the enzyme crucial for melanin production, which helps diminish dark spots and promote an even skin tone. Furthermore, it supports anti-aging by promoting collagen synthesis, enhancing skin elasticity, and boosting cellular vitality through mitophagy and ROS detoxification, contributing to cell renewal and improved skin resilience.

Key findings
- 01 In vitro assays have demonstrated that Paeonia lactiflora flower extract exhibits significant antioxidant properties against DPPH, ABTS, and FRAP radicals, potent antiglycation capacity, and substantial inhibition of tyrosinase, cyclooxygenase-2, and collagenase.
- 02 Cellular experiments indicate that peony flower extract can inhibit nitric oxide and inflammatory factor release, decrease reactive oxygen species levels, prevent cell apoptosis, and inhibit the activation of MAPK and NF-κB signaling pathways, suggesting a therapeutic effect on skin inflammation.

Stability
For optimal stability, a concentrated solution of peony flower extract is best diluted with water to achieve a pH of 6 ± 0.3 during preparation. Extremes, such as alkaline conditions or a pH around 3, can lead to the decomposition of its active substances, whereas a pH range of 5-7 supports stability.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) has not specifically assessed Paeonia Lactiflora Flower Extract. While a CIR review for *Paeonia suffruticosa*-derived ingredients noted insufficient data and did not include this specific extract, *Paeonia lactiflora root extract* has been deemed safe for cosmetic use up to a 1% concentration based on the Threshold of Toxicological Concern (TTC) approach. Generally, it is regarded as a safe ingredient in cosmetics with no widely known side effects or intolerances. However, individuals with known allergies to peonies or other related plants should exercise caution.
