How To Use

Application: Shake bottle well before each use. Prior to dispensing, leave the plastic lid in place, invert the bottle, and tap the top of the container several times into the palm of your hand. If you experience difficulty when dispensing, repeat this process and pump the product into your hand whilst inverted. Apply sparingly to cleansed, dry skin.

Frequency: Use twice daily, morning and evening, for optimal results.

Timing: Apply after cleansing and toning but before heavier serums, moisturisers, and sunscreen. Allow the serum to absorb fully before applying subsequent products.

Layering: The lightweight texture layers beautifully under moisturisers and sunscreens. Apply over the entire face, neck, and behind the ears for comprehensive coverage. During morning application, always follow with a broad-spectrum sunscreen as vitamin C can enhance photosensitivity.

Expert Tips: For best results, use consistently as part of your daily skincare regimen. The serum's colour may naturally turn slightly yellow over time; this does not affect product performance or efficacy.

FAQ

Q: How does C-ESTA Face Serum differ from other vitamin C products?
A: C-ESTA Face Serum features a unique lipid-soluble form of vitamin C (Ascorbyl Palmitate) rather than traditional water-soluble ascorbic acid. This innovative technology provides superior skin absorption and retention without requiring harsh acidity levels, making it significantly more tolerable for all skin types, including sensitive skin. In a published clinical study, C-ESTA demonstrated statistically superior results compared to a leading traditional vitamin C product, with participants preferring its feel, application, and scent.

Q: Can I use this serum if I have sensitive skin?
A: Yes, the C-ESTA Face Serum is specifically formulated to be non-acidic and non-irritating, making it suitable for sensitive skin. The lipid-soluble vitamin C technology delivers powerful antioxidant benefits without the irritation commonly associated with traditional vitamin C serums. However, as with any new skincare product, we recommend performing a patch test before full facial application. Speak to our experts if you have specific concerns about your skin's tolerance.

Q: When will I see results from using C-ESTA Face Serum?
A: Many users notice immediate improvements in skin texture and hydration, with the skin appearing smoother and more supple shortly after application. With consistent twice-daily use, you can expect to see progressive improvements in fine lines, wrinkles, facial contours, and overall skin tone within 4-8 weeks. The clinical study demonstrated statistically significant improvements in skin texture and reduction in the appearance of fine lines. For optimal results, our experts recommend using the serum as part of a comprehensive skincare regimen.

Q: What is DMAE and how does it benefit my skin?
A: DMAE (Dimethyl MEA) is a powerful compound that enhances the benefits of vitamin C by helping to visibly firm and tone the skin. It works to reduce the appearance of fine lines and wrinkles whilst giving facial contours a tighter, firmer, more lifted look. When combined with lipid-soluble vitamin C, DMAE creates a synergistic effect that addresses multiple signs of ageing simultaneously.

Q: Can I use C-ESTA Face Serum with other Jan Marini products?
A: Absolutely. The C-ESTA Face Serum is designed to integrate seamlessly into the Jan Marini Skin Care Management System and works beautifully with other professional-grade skincare products. Apply the serum after cleansing and before heavier treatments, moisturisers, and sunscreen. For personalised product layering guidance based on your specific skincare concerns, speak to our skincare experts.

Q: Why might the serum's colour change over time?
A: It is normal for the serum to develop a slight yellow tint over time. This colour change does not affect the product's performance or efficacy. The stable lipid-soluble form of vitamin C used in C-ESTA maintains its effectiveness throughout the product's shelf life, unlike traditional vitamin C formulations that can oxidise and lose potency quickly.
