Vitamin C Serum 15% – High-Performance Brightening & Antioxidant Treatment

This professional-grade serum delivers **15% active vitamin C (e.g., L-ascorbic acid or equivalent stable derivative)** in a carefully designed vehicle to promote clearer, brighter skin, support collagen production, and help defend against environmental stressors.

Core Ingredient
  • Vitamin C (active form): 15 %
  • Most studied form: L-ascorbic acid (widely shown to be effective). [oai_citation:0‡PMC](https://pmc.ncbi.nlm.nih.gov/articles/PMC5605218/?utm_source=chatgpt.com)
  • Other contributors: Derivatives or stabilised forms (optional depending on formulation).
Why It Works (Plain English)
  • Vitamin C is a major antioxidant in the skin: it neutralises free-radicals from UV or pollution. [oai_citation:1‡Harvard Health](https://www.health.harvard.edu/blog/why-is-topical-vitamin-c-important-for-skin-health-202111102635?utm_source=chatgpt.com)
  • Supports collagen production, helping reduce the look of fine lines and firmness loss. [oai_citation:2‡Healthline](https://www.healthline.com/health/beauty-skin-care/vitamin-c-serum-benefits?utm_source=chatgpt.com)
  • Helps fade dark spots and even out skin tone by inhibiting melanin formation. [oai_citation:3‡Cleveland Clinic](https://health.clevelandclinic.org/vitamin-c-serum?utm_source=chatgpt.com)
Why 15% Strength?
  • Clinical guidance suggests ~10-20% vitamin C is effective for skin benefit. [oai_citation:4‡ACOFP ORG](https://www.acofp.org/news-and-publications/journal/article-detail/vol-16-no-3-fall-2024/vitamin-c-topical-retinoids-sunscreen-in-clinical-practice-essentials-for-family-physicians?utm_source=chatgpt.com)
  • 15% provides a strong yet tolerable active level for many users when formulated properly.

Key Benefits & Evidence

  • Improves visible signs of photo-aging: fine/coarse wrinkles, uneven texture. [oai_citation:5‡Harvard Health](https://www.health.harvard.edu/blog/why-is-topical-vitamin-c-important-for-skin-health-202111102635?utm_source=chatgpt.com)
  • Brightens complexion and reduces hyperpigmentation/dark spots. [oai_citation:6‡Cleveland Clinic](https://health.clevelandclinic.org/vitamin-c-serum?utm_source=chatgpt.com)
  • Boosts skin-defence against environmental damage (e.g., UV + pollution) when used alongside SPF. [oai_citation:7‡WebMD](https://www.webmd.com/beauty/ss/slideshow-benefits-of-vitamin-c-for-skin?utm_source=chatgpt.com)

Usage Instructions

  • Use **morning or evening** on clean, dry skin—usually after cleansing and before moisturizer.
  • Start with every other night if your skin is new to potent actives, then progress to nightly as tolerated.
  • Important: Use broad-spectrum **SPF during daytime** — vitamin C enhances effects but does not replace sunscreen. [oai_citation:8‡WebMD](https://www.webmd.com/beauty/ss/slideshow-benefits-of-vitamin-c-for-skin?utm_source=chatgpt.com)

Formulation & Compatibility Notes

Packaging & Stability

  • Vitamin C is inherently unstable in air/light; ideal packaging is dark glass or air-less pump. [oai_citation:9‡PMC](https://pmc.ncbi.nlm.nih.gov/articles/PMC5605218/?utm_source=chatgpt.com)
  • Low pH (~3.0-3.5) for L-ascorbic acid increases penetration but may increase irritation risk. [oai_citation:10‡JCAD](https://jcadonline.com/topical-vitamin-c-and-the-skin-mechanisms-of-action-and-clinical-applications/?utm_source=chatgpt.com)

Compatible Actives

  • Pair with vitamin E, ferulic acid to boost antioxidant effect. [oai_citation:11‡Skin Ceuticals](https://www.skinceuticals.com/skincare/vitamin-c-serums/c-e-ferulic-with-15-l-ascorbic-acid/S17.html?utm_source=chatgpt.com)
  • Barrier-support actives (ceramides, glycerin, niacinamide) help tolerance.

Use Caution With

  • Highly acidic exfoliants or strong retinoids on the same night may increase irritation risk.
  • Discolouration (darkening of serum) indicates oxidation — discard. [oai_citation:12‡Vogue](https://www.vogue.com/article/how-to-use-vitamin-c-in-your-skin-care-routine-correctly?utm_source=chatgpt.com)
