What it is

Wrinkle-recovery & repair emulsion that reveals a fuller, softer appearance overnight

Private Nurse cocoons the skin in an intense moisture barrier, plumping up deep wrinkles and softening fine lines to reveal a noticeably fuller, softer, more radiant appearance by morning.

How It Works

Unprecedented 10% concentration of most powerful form of hyaluronic acid

Besides powerful peptides, anti-aging antioxidants and our proprietary MegaDose® Nutritional Complex, this rich therapy nourishes parched skin with the most potent form of hyaluronic acid, a natural compound abundant in the dermis of young skin, at an unprecedented 10% concentration of crosslinked sodium hyaluronate. This highly coveted ingredient, used in popular injectable fillers, has an unparalleled ability to penetrate and bind moisture to the skin. When applied topically, this unrivaled compound plumps up depressions, softens the appearance of fine lines and wrinkles and restores youthful fullness.

The Science

Clinically shown to reduce skin dryness & increase skin elasticity

In clinical tests, subjects showed a 70% reduction in skin dryness and 32% increase in skin elasticity four hours after application.

Formulator's Note

Private Nurse®

Perfected Night Cream

Let’s talk about hyaluronic acid. This acid is abundant in the dermis of young, healthy skin and is responsible for plumping up the skin. Right now it’s the new must-have cosmetic compound because it’s used in injectable wrinkle fillers like Restylane. This stuff is so effective that, after a few hours of immersion in a beaker of hyaluronic acid, a dried apricot will hydrate and plump back to its original shape. When I was looking for the special ingredient that would really make Private Nurse® a standout, I knew I had to get the most concentrated form of this ingredient. Normal hyaluronic acid is worth literally 1,000 times its weight in water, and it is included at 1% concentration in most skin care formulations. Crosslinked sodium hyaluronate, a super-concentrated form of this acid, is worth 5,000 times its weight in water—and I included it in Private Nurse® Perfected at 10% concentration. I really wanted people to be able to see and feel hydration they’ve never experienced before.


What We Tested

  • Skin hydration
  • Free-radical damage protection
  • Antioxidant efficacy
  • Skin irritation

What Techniques We Used

  • Corneometer®: This is the most accurate instrument of its kind on the market and is used to measure hydration levels in the outermost layers of epidermis.
  • Chroma Meter: Recommended by the CIE (Commission Internationale de l’Eclairage) for assessment of skin color, this instrument detects oxidative damage caused by free radicals. It measures the changes in skin color found in age spots and other skin pigmentation. It also detects protection against free-radical damage by antioxidant activity through assessment of improvements in evenness of skin tone, skin blotchiness, and/or pigmentation.
  • PRIMOS imaging system: This system captures the real-time three-dimensional structure of the skin surface. It can determine degrees of skin roughness and smoothness with a high-resolution rapid-video camera and a micromirror projection system, which illuminates a microscopic measurement area.

What We Found

  • Skin hydration had increased by 30% 4 hours after application, as measured by the Corneometer®.
  • Antioxidant activity increased by 44%, as measured by the Chroma Meter.
  • The average rating was 0 (on a scale of 0–4) for “No visible skin reaction.”
