Description

The Prequel Lucent-C Brightening Vitamin C Serum 30ml is a high-potency antioxidant serum designed to improve skin brightness, firmness, and overall radiance while helping protect the skin from environmental damage. It is formulated with 15% L-ascorbic acid (pure Vitamin C) alongside ferulic acid, ergothioneine, niacinamide, and inulin for enhanced antioxidant support and skin barrier care.

The formula focuses on several major skin concerns:

• Dullness and uneven tone
• Dark spots and post-acne marks
• Fine lines and loss of firmness
• Environmental stress and oxidative damage

Key ingredients include:

• 15% L-ascorbic acid: helps brighten skin, support collagen production, and improve discoloration
• Ferulic acid + ergothioneine: powerful antioxidants that help stabilize Vitamin C and defend against free radicals
• Niacinamide: helps strengthen the skin barrier, smooth texture, and improve uneven tone
• Inulin: a prebiotic ingredient that helps support skin balance and hydration

The serum has a lightweight, watery texture that absorbs quickly and layers well under moisturizer and sunscreen. It is fragrance-free, non-comedogenic, and dermatologist-developed. Clinical claims from the brand report improvements in radiance after 4 weeks and visible firmness and texture improvement after 8 weeks of use.

Because this is a true L-ascorbic acid Vitamin C serum, it has a low pH and may cause tingling or irritation on sensitive skin, especially when first introduced. The brand specifically recommends patch testing and gradual use for sensitive or reactive skin types.

Reddit users frequently compare it favorably to more expensive Vitamin C serums because of its strong ingredient profile. Some users praise it for improving smoothness and glow, while others mention the typical “hot dog water” smell associated with ferulic acid formulas and note that the serum should remain clear to pale yellow to avoid oxidation concerns.
