Science
Mechanism of Action
This ingredient operates via several synergistic mechanisms. Its potent antioxidant activity stems from a rich content of phenolic compounds, particularly rosmarinic acid, which effectively scavenges free radicals, diminishes intracellular reactive oxygen species (ROS), and safeguards cellular integrity against oxidative damage. It also exhibits anti-inflammatory effects that soothe irritated skin. Furthermore, its antimicrobial and antifungal properties may benefit blemish-prone skin by mitigating inflammation and reducing harmful bacterial presence. For oily skin types, it acts as an astringent to refine pores and balance sebum levels, while also promoting skin healing and reducing post-inflammatory hyperpigmentation.

Key findings
- 01 Demonstrated the most significant reduction in blood vessel visibility (antiangiogenic effect) in an in ovo CAM assay, without observed vascular toxicity.
- 02 Showed a reduction in thin capillaries (antiangiogenic effect) in an in ovo CAM assay.
- 03 Exhibited superior antioxidant activity, registering an Antioxidant Activity (AOA) of 49.11% in aqueous extracts.
- 04 Topical application on SKH-1 mice resulted in enhanced skin hydration, reduced erythema, and decreased transepidermal water loss. In HaCaT cells under oxidative stress, rosmarinic acid from the extract reduced intracellular ROS, boosted cell viability, and offered protection against H2O2-induced damage.
- 05 Effectively scavenged DPPH radicals in a concentration-dependent manner.

Safety Profile
Generally deemed safe and non-toxic at concentrations up to 5%. However, higher concentrations may lead to irritation, particularly for sensitive skin, due to the presence of essential oil and fragrance components. Patch testing is advised. The FDA recognizes 'BALM LEAVES, EXTRACT (MELISSA OFFICINALIS L.)' as GRAS for specific food uses, but this does not equate to a cosmetic safety review by bodies like CIR or SCCS.
