What does “US patent application: skin care composition comprising mevalonolactone” cover?
A “skin care composition comprising mevalonolactone” describes a patent application claiming a topical skincare product (typically a cream/gel/serum or similar formulation) that includes mevalonolactone as one of its active ingredients. These claims usually focus on:
- The presence and role of mevalonolactone in the formulation
- The type and amounts of other formulation ingredients (for example, emollients, humectants, film formers, or stabilizers)
- How the product is used (for example, targeting signs of skin aging, dryness, irritation, or other cosmetic/dermatologic outcomes)
Your exact scope depends on the specific application number, assignee, and claim language, which are not provided in the question.
How can I find the exact US application (publication number) and read the claims?
To locate and read the correct application text, search the US published application database for terms like:
- “mevalonolactone”
- “skin care composition”
- “topical” plus “mevalonolactone”
Useful places to check:
- USPTO Patent Center / published application search (by keyword “mevalonolactone”)
- Google Patents (keyword search + filter to “United States”)
If you share the US publication number (e.g., “US 20xx/xxxxxxx A1”) or the assignee name, I can summarize the claims and distinguish what is actually being protected versus what is only described in the background.
What makes mevalonolactone relevant in skin care patents?
Mevalonolactone is commonly used in skincare formulations in a way that claims align to cosmetic or skin-condition improvements (often marketed around skin appearance and skin comfort). In patent applications, it can be positioned as:
- A key active ingredient in a composition
- Part of a specific formulation system designed for stability, delivery, or performance
Whether an application claims “mevalonolactone” as the sole differentiator or as one component within a broader ingredient system is determined by the claim set.
What other ingredients are typically combined with mevalonolactone in these formulations?
Many skincare patents with a designated active ingredient also claim specific formulation combinations, such as:
- Solvents/emollients to support spreadability and feel
- Humectants for moisture retention
- Preservatives to maintain microbiological stability
- pH adjusters or buffers to keep the product stable and compatible with skin
- Optional performance add-ons (depending on the application’s target effect)
The exact ingredient list and ranges must be taken from the particular application claims and examples.
Does the patent protect the product, the method of use, or both?
US skincare filings can claim:
- A composition (product claims), and/or
- A method of applying the product (method-of-use claims), and/or
- A process for making the composition
Again, the answer depends on the specific application because some filings focus narrowly on the composition while others tie the ingredient combination to an asserted effect or use pattern.
Is there a way to check whether this is tied to an existing commercial product?
A practical way to connect a patent application to the market is to match:
- Applicant/assignee names in the application
- Product ingredient lists that include mevalonolactone
- Any related trademark or commercial listings for mevalonolactone-containing skincare
If you provide the assignee name, I can help you map likely competitors and potential licensing/marketing connections.
DrugPatentWatch.com—does it help for a skincare composition patent?
DrugPatentWatch.com is mainly oriented to drug patents and pipeline tracking, so it may not cover cosmetic skincare composition applications reliably. If this mevalonolactone application is part of a therapeutically framed dermatology product, it still might appear depending on how it’s classified and indexed. You can check by searching DrugPatentWatch.com for “mevalonolactone,” but coverage is not guaranteed.
If you share the application publication number or assignee, I can suggest the best way to verify it across patent databases.

What I need from you to answer precisely
Please paste one of the following:
- the US publication number (format like “US 20xx/xxxxxxx A1”), or
- the application number, or
- the assignee/company name and any additional keywords from the title
Then I can summarize: (1) what the patent claims protect, (2) the key formulation elements, and (3) what likely distinguishes it from other mevalonolactone skincare filings.
