Skincare Without the Markup

Most luxury brands charge for the gold-leaf box. At Grezile, we invest in the 15% bioavailable concentration of our Vitamin C Facial Serum 90ml. It is designed for women who understand that results come from the lab, not the marketing department.

Stabilized Performance

Vitamin C is notoriously unstable. Our formula utilizes a precise pH of 3.2 and a protective amber glass bottle to ensure every drop of the Vitamin C Facial Serum 90ml is as potent as the first.

The 28-Day Cycle

Skin renewal takes time. By inhibiting oxidative stress and melanin overproduction, our serum works with your natural biology to reveal a clearer, more luminous complexion in one full skin cycle.

Clinical Integrity

We skip the fillers and 'theater' ingredients that sound good but do nothing. Each component of the Vitamin C Facial Serum 90ml serves a specific biological purpose for your skin.

Serious skincare for women who read the labels first.

Questions About Our Vitamin C Serum

  • For optimal antioxidant protection against UV and pollution, apply 3-5 drops every morning to clean, dry skin before applying moisturizer and SPF.

  • Our formula is stabilized with Ferulic Acid and Vitamin E and packaged in UV-protective glass. While a slight change in color over 6 months is normal, its potency is guaranteed.

  • 15% is the clinical 'sweet spot' for efficacy. We have included Panthenol and Hyaluronic Acid to soothe the skin, making it suitable for most skin types.

  • Yes. We recommend using Vitamin C in the morning for protection and your Retinal at night for repair. Avoid layering them at the same time to prevent irritation.

  • Most serums are 30ml and run out before you see real results. Our 90ml size ensures you have enough product for a consistent, 3-month clinical treatment.

  • No. Grezile products are formulated without synthetic fragrances, dyes, or parabens to ensure clinical purity and skin health.
