Science
Mechanism of Action
As a derivative of mevalonic acid, Mevalonolactone plays a crucial role in the mevalonate pathway, which is vital for producing cholesterol, ceramides, fatty acids, and other key biomolecules. It actively stimulates de novo cholesterol synthesis and promotes epidermal permeability barrier homeostasis by boosting ABCA12 expression and facilitating lipid transport to lamellar granules. This action fortifies the skin barrier, reducing transepidermal water loss and protecting against environmental aggressors. Furthermore, it aids in the production of coenzyme Q10 and dolichol, providing antioxidant protection and supporting proper protein function. Mevalonolactone also offers hydration by forming hydrogen bonds, calms irritation, and encourages cell renewal through pathways similar to retinoids, typically with superior tolerability.

Key findings
- 01 Topical application of a milky lotion containing 0.1% mevalonolactone was shown to alleviate deterioration of the stratum corneum barrier function, particularly beneficial for dry skin during winter months.
- 02 For related mevalonic acid, it is suggested that users commence with lower concentrations (around 0.5-1%) and gradually increase as tolerated to minimize potential irritation.

The Formula
Formulation
Stability
Mevalonolactone can interconvert with mevalonic acid. The lactone form is susceptible to hydrolysis in strong basic solutions. Aqueous solutions are not advised for storage beyond one day due to potential instability. Optimal stability in formulations is suggested within a pH range of 6 to 9.
Safety
Safety Profile
The CIR Expert Panel found insufficient data on Mevalonolactone, classifying it within the 'Glycolactones' family, requiring further impurity and cosmetic-specific manufacturing data for a complete safety determination. It is currently on the priority list for review. While cosmetic ingredients do not require FDA approval, manufacturers are responsible for product safety. No specific SCCS opinion for Mevalonolactone was identified. Incidecoder rates it as 'good' with low irritancy and comedogenicity.

Verdict
Mevalonolactone demonstrates promising benefits for barrier enhancement and skin regeneration with low irritation, yet its current CIR status indicates a need for more comprehensive safety data regarding impurities and manufacturing processes to fully establish its long-term safety profile.
