Learn the correct way to use Dermaesthetics C-Lester Topical Vitamin C20 Serum for brighter, firmer skin. Step-by-step application tips and common mistakes to avoid.

Quick Answer

Apply C-Lester Topical Vitamin C20 Serum on clean, dry skin in the morning, before moisturizer and sunscreen. Use 3-4 drops, gently pressing into face and neck, avoiding the eye area.

Why Morning Application Works Best

Vitamin C is an antioxidant that protects skin from environmental aggressors like pollution and free radicals encountered during the day. Using C-Lester in the morning helps neutralize these stressors before they can cause damage. Evening use is also possible, but morning maximizes its protective benefits alongside sunscreen.

What to Expect with High-Concentration L-Ascorbic Acid

This serum contains a high concentration of L-Ascorbic Acid, which can cause a mild tingling or warmth on first use. This is normal and usually subsides after a few days as your skin adjusts. If redness or irritation persists, reduce frequency to every other day or mix a drop with your moisturizer.

Step-by-Step Application Guide

  1. Cleanse and Dry: Wash your face with a gentle cleanser and pat completely dry. Vitamin C is water-soluble and absorbs best on bare, dry skin. A common mistake is applying to damp skin, which dilutes the serum and reduces efficacy.
  2. Apply 3-4 Drops: Dispense 3-4 drops of C-Lester Serum onto your fingertips. Do not apply directly to the face to avoid waste. Gently press and pat the serum into your face and neck, avoiding the eye area. Do not rub or pull the skin. Start with 3 drops; increase to 4 if your face and neck feel evenly covered.
  3. Wait 60 Seconds: Allow the serum to absorb fully for about one minute before layering other products. This prevents pilling and ensures the vitamin C penetrates effectively. A common mistake is rushing to the next step, which can reduce the serum's brightening benefits. Use this time to apply serum to your hands or neck if needed.
  4. Follow with Moisturizer and Sunscreen: After the serum has dried, apply your regular moisturizer, then finish with a broad-spectrum sunscreen of SPF 30 or higher. Vitamin C and sunscreen work synergistically to enhance protection against UV damage and environmental stressors. Always use sunscreen after vitamin C in the morning; it is not a replacement.
