Frequently Asked Questions
How do I use The Vitamin C 23 Serum and how often should I apply it?
Apply 2-3 drops of the serum to clean, dry skin in your morning routine. Start by using it 2-3 times per week to allow your skin to adjust to the high 23% vitamin C concentration, then gradually increase to daily use. Always follow with sunscreen during the day as vitamin C can increase photosensitivity.
What are the main benefits of using this 23% Vitamin C serum?
This serum provides multiple benefits including fading acne scars and dark spots, evening out skin tone, brightening dull skin, reducing fine lines and wrinkles, and improving skin firmness and elasticity. The high 23% pure vitamin C concentration combined with vitamin E, hyaluronic acid, and allantoin delivers powerful antioxidant protection and anti-aging results.
Is this serum suitable for sensitive skin, and are there any side effects?
While the serum is formulated to be hypoallergenic, the high 23% vitamin C concentration may cause irritation for sensitive skin types. Common initial reactions include mild tingling, redness, or dryness. It's recommended to patch test first and start with less frequent application. If irritation persists, discontinue use and consult a dermatologist.
How should I store this vitamin C serum to maintain its effectiveness?
Store the serum in a cool, dark place away from direct sunlight and heat, preferably in the refrigerator. Vitamin C is sensitive to light and air, so always tighten the cap securely after use. The serum should maintain its clear to light yellow color - if it turns brown or orange, it has oxidized and should be replaced.
How long does it take to see results and what is the shelf life of this product?
Most users begin to notice brighter, more even skin tone within 2-4 weeks of consistent use, with more significant improvements in dark spots and fine lines visible after 6-8 weeks. The unopened product typically has a 2-3 year shelf life, but once opened, it should be used within 6-12 months for optimal potency and effectiveness.
Thoroughly cleanse your face to remove any dirt, oil, or makeup.Take a small amount of the serum with your fingertips or use the dropper to apply it to your face.Gently massage in circular motions to help the serum absorb into your skin.After applying the serum, follow with a moisturizer to lock it in and provide additional hydration.If using the serum in the morning, make sure to finish your skincare routine with a broad-spectrum sunscreen to protect your skin from UV rays.
