Description
The Purest Solution 20% Vitamin C + 0.5% Ferulic Acid Brightening Serum (30ml)
The Purest Solution Vitamin C Serum is a professional-grade brightening face serum from The Purest Solutions (Turkey) containing 20% L-Ascorbic Acid — the gold standard form of Vitamin C in skincare — stabilised and amplified by 0.5% Ferulic Acid and a prebiotic complex. This is one of the highest OTC Vitamin C concentrations available, delivering maximum antioxidant protection, brightening, and skin lightening results.
Key Ingredients
- 20% L-Ascorbic Acid: The most potent and clinically researched form of Vitamin C for brightening, collagen synthesis, and antioxidant skin defence. OTC — no prescription required despite the high concentration.
- 0.5% Ferulic Acid: Stabilises L-Ascorbic Acid to extend shelf-life and doubles its photoprotective antioxidant efficacy when combined with Vitamin C.
- Prebiotic Complex: Supports the skin microbiome for a healthier, more resilient skin barrier.
What It Does
Targets dullness, dark spots, fine lines, and hyperpigmentation through maximum-strength antioxidant brightening. Works as the morning step of a complete imported derma skincare routine: Vitamin C serum in the morning + SPF, Retinol serum in the evening.
How to Use
Apply 1–2 drops to cleansed face and neck. Allow to absorb before moisturiser. Use morning and/or evening. Always follow with SPF 30+ sunscreen in the morning. Patch test before first use. Store in a cool, dark location to preserve potency.
Precautions
- For external use only. Avoid contact with eyes and mouth.
- Perform patch test before full application — high Vitamin C concentrations may cause initial tingling.
- Store in a cool, dark place.
- Keep out of reach of children.

FAQs
Is 20% Ascorbic Acid safe for home use without a prescription?
Yes. L-Ascorbic Acid (Vitamin C) is an OTC cosmetic ingredient regardless of concentration. While 20% is a high professional-grade strength, it does not require a prescription. Those new to Vitamin C serums should start with every-other-day application to build tolerance before daily use.
What does Ferulic Acid do in this serum?
Ferulic Acid serves two critical roles: it stabilises L-Ascorbic Acid (which oxidises quickly without stabilisation) and it doubles the photoprotective antioxidant efficacy of the formula. The classic 20% Vitamin C + 0.5% Ferulic Acid combination is a benchmark in professional skincare.
How is this product different from The Purest Solution Retinol Serum?
The Vitamin C serum focuses on brightening, dark spot reduction, and antioxidant UV protection — best used in the morning. The Retinol serum (1% Retinol + Ceramides) focuses on anti-aging, wrinkle reduction, and skin renewal — best used in the evening. The two complement each other in a morning/evening split routine.
Can I use this serum on sensitive skin?
High-concentration Vitamin C can cause tingling or temporary redness on sensitive skin. Patch test first. Build up gradually from every-other-day use. If persistent irritation occurs, discontinue and consult a dermatologist.
Does this require a prescription?
No. This is an OTC cosmetic serum. No prescription is needed.
