SKIN Functional 10% Ascorbic Acid + 3% Ferulic Acid Review

October 26, 2026 · FregranceX Team

SKIN Functional 10% Ascorbic Acid + 3% Ferulic Acid ( priced at R532 ) is a high-potency antioxidant serum designed to target stubborn hyperpigmentation, uneven skin tone, and fine lines. By combining pure L-Ascorbic Acid with Ferulic Acid, this formulation neutralises free radical damage while boosting collagen synthesis for radiant, resilient skin across South Africa.

Understanding the Power of L-Ascorbic Acid and Ferulic Acid

Vitamin C is widely regarded by dermatologists as a gold-standard topical antioxidant, but not all Vitamin C formulations are created equal. Pure L-Ascorbic Acid is the most biologically active form of Vitamin C. At a 10% concentration, it effectively brightens dull skin and inhibits melanin production without triggering excessive irritation, making it ideal for both beginners and experienced skincare users.

The addition of 3% Ferulic Acid is what elevates this serum. Ferulic Acid is a plant-based antioxidant that stabilizes L-Ascorbic Acid, preventing rapid oxidation and doubling its photoprotective efficacy against environmental stressors. Together, this combination works synergistically to defend your cellular matrix against urban pollution and solar radiation.

Formulated for the South African Climate

Living in South Africa presents unique skincare challenges due to high UV indices and stark climate variations between provinces. Whether you are dealing with humid summers in Durban, intense heat in Johannesburg, or dry, windy winters in Cape Town, your skin requires daily protection against oxidative stress.

High UV Exposure and Hyperpigmentation

South African sun exposure is among the highest globally, leading to dark spots, sun spots, and melasma. Applying SKIN Functional 10% Ascorbic Acid + 3% Ferulic Acid every morning beneath a broad-spectrum sunscreen creates a dual line of defence. While sunscreen reflects or absorbs UV rays, the antioxidant serum neutralises free radicals that penetrate the skin barrier.

Adapting to Seasonal Changes

During dry Highveld winters, skin often becomes dehydrated, accentuating fine lines. In summer, humidity increases sebum production, making heavy creams feel uncomfortably greasy. This formulation features a light, water-based fluid texture that absorbs quickly without leaving a tacky residue, making it ideal for layering throughout the year across all South African weather conditions.

Key Skin Benefits

  • Fades Dark Spots: Suppresses excess melanin formation to diminish post-inflammatory hyperpigmentation and sun damage.
  • Boosts Collagen: Stimulates natural collagen synthesis to improve skin firmness and smooth fine lines.
  • Neutralises Free Radicals: Shields vulnerable skin cells against damage caused by UV radiation, pollution, and blue light.
  • Enhances Radiance: Gently restores vitality and a natural glow to tired, uneven complexions.

How to Incorporate Pure Vitamin C into Your Routine

Consistency and proper application technique are crucial when using active serums. Follow these simple steps every morning for optimal results:

Step 1: Cleansing

Start with a mild, pH-balanced cleanser. Avoid harsh, stripping face washes that compromise your lipid barrier prior to active application.

Step 2: Serum Application

Dispense 3 to 4 drops of SKIN Functional 10% Ascorbic Acid + 3% Ferulic Acid onto clean, dry skin. Press gentle drops into the face, neck, and chest. Allow the serum to absorb for 1 to 2 minutes before applying your next layer.

Step 3: Moisturising and Barrier Support

Lock in hydration with a suitable moisturizer. If you suffer from dry skin or compromised barrier function elsewhere on the body, using products formulated with urea—such as an intensive eucerin urea or eucerin with urea cream—helps restore essential moisture levels. Taking care of your lips with a dedicated eucerin lip balm completes your protective morning routine.

Step 4: Sunscreen

Always finish your morning routine with a broad-spectrum SPF 30 or SPF 50 sunscreen. Antioxidants and sun protection work in tandem to shield your skin from sun damage.

Stability, Storage, and Packaging

L-Ascorbic Acid can be prone to oxidation when exposed to heat, light, and air. Skin Functional packages this formulation in an amber glass bottle with a precise dropper to minimise exposure to sunlight. To extend the shelf life of your serum in warm South African homes:

Keep the bottle tightly sealed in a cool, dry place away from direct sunlight. Storing your serum in a skincare fridge or a cool bedroom cupboard during hot summer months helps maintain peak potency.
