Science
Mechanism of Action
The efficacy of Melissa Officinalis Leaf Powder is largely attributed to its wealth of bioactive compounds, including rosmarinic acid, flavonoids, caffeic acid, and ferulic acid. These constituents exert powerful antioxidant effects by neutralizing free radicals, thereby protecting skin cells from oxidative stress. Its anti-aging mechanism involves promoting Endo180 production, which is crucial for maintaining collagen levels and visibly reducing wrinkles. Furthermore, it exhibits anti-inflammatory properties by inhibiting pro-inflammatory cytokines and enzymes like COX and LOX, effectively calming redness and irritation. The ingredient also contributes to skin hydration by minimizing transepidermal water loss, offers mild astringent qualities, and possesses antimicrobial and photoprotective potential against UVB-induced damage.

Key findings
- 01 An extract demonstrated a 178.1% increase in Endo180 mRNA and a 127.4% increase in Endo180 protein production in dermal fibroblasts in vitro at 50 μg/mL.
- 02 At 200 μg/mL, an extract almost completely inhibited the decrease in Endo180 and type I collagen production in UVB-irradiated keratinocyte-conditioned medium in vitro.
- 03 Topical application of a formulation containing Melissa Officinalis extract significantly reduced eye-corner wrinkles in a double-blind, randomized, placebo-controlled human study involving 20 healthy women over 8 weeks.
- 04 Topical application of an extract at 100-500 µg/mL on SKH-1 mice resulted in reduced thin capillaries, enhanced skin hydration, decreased erythema, and lower transepidermal water loss levels.
- 05 An extract enhanced keratinocyte survival, reduced UVB-induced reactive oxygen species (ROS) and DNA damage, and promoted melanogenesis in human keratinocytes in vitro, suggesting photoprotective potential.

Dusting Analysis
While named 'Leaf Powder,' the significant clinical efficacy data primarily pertains to concentrated extracts of Melissa Officinalis. Incorporating the raw leaf powder at very low percentages (typically below 0.5-1%) without evidence for equivalent efficacy at those concentrations would likely be for label claim purposes rather than delivering true active benefits in a precision skincare formulation. For active benefits, a standardized extract is generally preferred.

Formulation
Stability
No specific optimal pH range for stability was identified. Extracts are typically prepared using water, glycerin, or alcohol as solvents, suggesting stability across common cosmetic pH ranges for these types of formulations.
Safety
Safety Profile
Melissa Officinalis Leaf Extract is widely considered safe and non-toxic within recommended concentrations (up to 5%). However, due to the presence of essential oil and fragrance components, higher concentrations of the extract or direct application of the powder may induce irritation, particularly on sensitive skin. Patch testing is advised prior to full application. There is no direct CIR, SCCS, or FDA cosmetic status specifically for 'MELISSA OFFICINALIS LEAF POWDER' in the provided data, but lemon balm generally has a long history of safe use in various applications.
