Humectant water phase
Glycerin and propylene glycol support a comfortable, water-rich application.
Rav Perle
Brightening Antioxidant Serum
A fragrance-free serum with 3% niacinamide plus tocopherol and ubiquinone in its suspended bead phase. Choose Rav Perle for brightening and antioxidant support.
Product promise
Brightening support with a distinct antioxidant phase.
The formula is organised as a water-rich serum and a structured bead. Each part has a defined role rather than a decorative ingredient story.
Niacinamide at 3%
Supports the brightening direction at a measured concentration.
Structured bead
Phenyl trimethicone, dimethicone, tocopherol and ubiquinone form the suspended oil-silicone phase.

Performance Testing
The current workbook records sensory attributes, pH over eight days and three day-seven spread replicates. These measurements describe early formulation behaviour; they do not establish clinical efficacy or long-term stability.

How to read
The outer ring means more of the named attribute, not a better result. Each score follows the workbook’s own 0–10 sensory anchors.

| Softness during use | 10 | 70 µL · assessed while spreading |

Preliminary in-house screening. Long-term stability, preservative efficacy and dermatological testing would be required before final commercial claims.

Method note
Each mean is based on three pH-meter readings recorded by the same operator. The line shows the observed short screen only; it is not a shelf-life stability result.

Calculation note
The displayed 2.85 mm mean is recalculated from the three replicate mean diameters: 2.85, 2.80 and 2.90 mm. Marker shapes and direct labels distinguish replicates without relying on colour alone.

Ingredient Evidence
The selected literature informs the formulation direction. It does not represent clinical testing of the finished product.
Niacinamide direction3% in the current batch formula
Informs the brightening and more even-looking tone direction without proving a finished-product outcome.
Humectant directionGlycerin · propylene glycol · sodium hyaluronate
Supports the hydration role within the serum step.
Antioxidant bead phaseTocopherol · ubiquinone
Explains why the formula uses a distinct structured phase; it does not establish clinical performance.

Lab notebook
Development Story
“Rav Perle was designed to pair a measured brightening direction with a distinct antioxidant phase.”
The development direction balances 3% niacinamide, an antioxidant bead, reliable redispersion and comfortable application. It is one of three serum options, not a mandatory layer beneath another serum.
- Reliable redispersion
- Comfortable absorption
- Brightening and antioxidant direction
- Consistent dose
