Geek & Gorgeous Vitamin C Serum 15% (Ascorbic Acid) — 1 oz water‑light formula with Ferulic Acid & Vitamin E for brightening

Geek & Gorgeous C-Glow is a water-light 15% pure vitamin C (ascorbic acid) serum formulated with ferulic acid and vitamin E to brighten skin, help protect against environmental stressors, and visibly even tone.

Designed to deliver a visible glow without heavy oils or sticky residue, C-Glow combines a high concentration of pure vitamin C with stabilizing antioxidants in a low-pH, fast-absorbing texture. The formula aims to provide antioxidant support and improve skin radiance while remaining fragrance-free and suitable for most skin types. Store unopened bottles in the fridge to extend freshness and follow with SPF in the morning for best daytime protection.

How should I add C-Glow into my skincare routine?

Apply C-Glow after cleansing on dry skin and before thicker serums or creams so it can absorb quickly. Use a few drops across face and neck, press gently to distribute, then follow with moisturizer and sunscreen in the morning. In evening routines you can layer serums afterward as needed.

• Apply to clean, dry skin—face and neck.
• Use 3–4 drops; pat in until absorbed.
• Layer heavier serums/creams after application.
• Always use SPF 30+ when used in daytime routines.

Is this serum suitable for sensitive or acne-prone skin?

C-Glow is lightweight and formulated to be malassezia-safe, gluten-free, and free from essential oils and fragrance, which helps reduce irritation triggers for many people. However, its low pH (~3–3.4) and 15% ascorbic acid concentration mean those with highly reactive or redness-prone skin should patch-test first or introduce it slowly to assess tolerance.

• Fragrance-free and essential oil–free for fewer irritants.
• Malassezia-safe for many with fungal acne concerns.
• Patch-test recommended for very sensitive skin.
• Start every other day, then increase frequency if tolerated.

What benefits do ferulic acid and vitamin E add?

Ferulic acid and vitamin E are antioxidants included to stabilize vitamin C and enhance its effectiveness, helping to slow oxidation so the formula stays active longer. Together these ingredients support the vitamin C’s performance, contributing to improved radiance and a more even-looking skin tone over time.

• Ferulic acid helps stabilize and boost antioxidant power.
• Vitamin E supports skin barrier and extends vitamin C efficacy.
• Combined blend aims to reduce visible environmental dulling.
• Works synergistically with ascorbic acid for potency.

How should I store C-Glow and what is its shelf life?

The official unopened shelf life is 8 months from production; refrigeration prolongs freshness and can keep the serum stable beyond that window. To minimize oxidation, keep the bottle tightly closed, avoid direct sunlight, and store in a cool place—preferably the fridge once opened.

• Official unopened shelf life: 8 months from production.
• Store in the fridge to slow oxidation and extend usability.
• Keep away from direct heat and sunlight; close cap tightly.
• If color or scent changes unexpectedly, discontinue use.

Who this is for: C-Glow suits anyone seeking a potent, fast-absorbing vitamin C serum to boost radiance and even skin tone—particularly those who prefer lightweight, fragrance-free formulations. It’s a good match for normal, combination, oily, and many acne-prone or fungal-acne–sensitive skin types; those with very reactive skin should introduce it gradually or consult a specialist. Pair with daily sunscreen and consistent moisturizing for best visible results.
