What are the key silicate ingredients?

Plexaderm says its Rapid Reduction Serum uses silicate technology to create an invisible layer on the skin's surface. The ingredient list names sodium silicate and magnesium aluminum silicate. That supports identifying them as the formula's listed silicate components, but the public label does not reveal their concentrations or isolate the effect of either ingredient in the finished product.

The company describes the visible result as temporary and surface-level. Ingredient data alone cannot verify how long a result will last for a particular person or how the complete formula will behave with another skincare or makeup product.

Does Plexaderm list a drug active ingredient?

No drug active ingredient is designated in the official cosmetic ingredient list. The phrase “active ingredient” is often used informally for the ingredients associated with a product's main cosmetic effect, but that is different from an active ingredient declared on an over-the-counter drug label.

What does the list say about phenoxyethanol?

Phenoxyethanol appears near the end of the published list. The European Commission's Scientific Committee on Consumer Safety concluded that 2-phenoxyethanol is safe as a cosmetic preservative at a maximum concentration of 1.0%. Plexaderm's public ingredient list does not publish a percentage, so its concentration cannot be calculated from the label position.

What can an ingredient list not tell you?

• The exact concentration of each ingredient
• Whether the finished product will irritate or suit a particular person
• How the formula interacts with another product or a medical condition
• Whether marketing results will be reproduced for every user
• Whether an older package contains the current formula

Stop using a cosmetic if it causes irritation and follow the package directions. This ingredient explanation is educational and is not a diagnosis or individualized medical advice.

How can developers analyze this list?

Preserve the original label tokens, then normalize each INCI name and resolve it to a canonical ingredient record. Do not infer concentration, finished-product safety, or clinical performance from list position.
