Why Kyle Richards Chooses NEOSTRATA

Kyle Richards, known for her vibrant skin on Real Housewives of Beverly Hills, attributes her glowing complexion in part to NEOSTRATA 15% Vitamin C + PHA Serum. Richards reportedly values the formula for its high concentration of vitamin C, gentle exfoliating properties, and visible improvements in tone and brightness after consistent use.

  • High concentration of Vitamin C for maximum effectiveness.
  • Gentle Polyhydroxy Acids (PHA) for non-irritating exfoliation.
  • Suitable for use under makeup—Richards cites the pleasant texture and quick absorption.
  • Designed to brighten, even out skin tone, and tackle dark spots without causing irritation, making it a favorite among those with sensitive skin.

Richards’ endorsement underscores a rising trend: consumers are seeking out dermatologist-approved, clinically-backed formulas that deliver both instant and long-term results.

The Science and Ingredients Behind NEOSTRATA’s Serum

The formulation of NEOSTRATA 15% Vitamin C + PHA Serum is what sets it apart from other serums. Here’s what makes this product scientifically compelling:

  • 15% Pure Vitamin C (L-Ascorbic Acid): Delivers potent antioxidant protection, helps fade hyperpigmentation, and brightens overall complexion.
  • Polyhydroxy Acids (PHA): Next-generation gentle exfoliators that work to smooth skin and enhance the penetration of vitamin C, all with minimal irritation.
  • Additional Skin Benefits:
    • Reduces oxidative stress caused by pollution and sun exposure.
    • Improves the appearance of fine lines and wrinkles.
    • Evens out skin texture and tone.
    • Targets dark spots for brighter, more illuminated skin.

Dermatologists frequently recommend vitamin C serums for their powerful protective and rejuvenative effects, and the inclusion of PHA in NEOSTRATA’s formula marks a significant advancement for users with sensitive skin or those prone to irritation.

Application Tips for Maximum Results

NEOSTRATA recommends a specific skincare routine to enhance product performance and safety:

  • Apply to clean, dry skin (face, neck, and décolletage) every morning.
  • Follow with a NEOSTRATA moisturizer to lock in hydration and active ingredients.
  • Storage: Keep upright in a cool, dark place to preserve potency. The formula may slightly change color over time but remains effective.
  • Sun Protection: Use a broad spectrum SPF 30+ every day. Even on cloudy days, sunscreen helps prevent further dark spots or uneven skin tone. Reapply every two hours for optimal protection.
  • For an enhanced brightening regimen, use NEOSTRATA Illuminating Serum with niacinamide and NeoGlucosamine in the evening to target persistent dark spots and unevenness.

Users report that the lightweight, smooth texture glides easily on the skin and works well under makeup, making it convenient for daily use and layering within existing routines.
