ludient Radiance Glass Serum — 20% Niacinamide & Glutathione, Vitamin C for Even Tone (1.69 fl oz)

ludient Radiance Glass Serum is a lightweight face serum combining 20% niacinamide, glutathione, vitamin C, ferulic acid and an 8-complex hyaluronic acid system to visibly even tone and boost radiance for a glass-skin finish.

Formulated as a targeted step in a Korean-inspired routine, this serum blends high-concentration brighteners with multi-weight hydration to address dullness, uneven skin tone and rough texture. The fast-absorbing texture layers well under moisturizers and sunscreens, and the formula is presented as an AI-optimized mix informed by broad skin-scan data to prioritize tolerance and efficacy.

How quickly will I see a difference in dark spots and uneven tone?

Results vary by skin type and spot depth, but many users notice improved brightness and softer discoloration within weeks of consistent use. The concentrated 20% niacinamide and antioxidant pairing helps accelerate visible tone correction when used regularly morning and evening.

• High-strength 20% niacinamide targets pigment irregularities.
• Glutathione and vitamin C support surface radiance.
• Consistent daily use needed for cumulative effect.

Is this serum suitable for sensitive or reactive skin?

The product is designed for broad tolerance with a weightless base, but the high actives concentration can be potent for very reactive skin. Patch-testing is recommended; if irritation occurs, reduce frequency or consult a skincare professional.

• Fast-absorbing, non-greasy texture reduces layering irritation.
• AI-informed formulation aims to balance efficacy and comfort.
• Patch test: apply a small amount on the inner forearm for 24–48 hours.

How should I incorporate this into my daily skincare routine?

Apply a few drops to cleansed skin after toner and before moisturizer, both morning and evening as tolerated. In the morning, always follow with a broad-spectrum sunscreen to protect newly brightened skin and prevent future discoloration.

• Step 1: Cleanse and tone.
• Step 2: Apply 2–3 drops of ludient Radiance Glass Serum.
• Step 3: Seal with moisturizer and SPF in the daytime.

What key ingredients make this a "glass skin" serum?

The serum combines a potent brightening trio—niacinamide, glutathione and vitamin C—with ferulic acid for antioxidant support and an 8-complex hyaluronic acid system for multi-depth hydration. That mix smooths texture, reduces the look of discoloration, and builds surface dewiness associated with glass-skin looks.

• 20% niacinamide: targets tone and texture.
• Glutathione + vitamin C + ferulic acid: antioxidant radiance blend.
• 8-complex hyaluronic acids: layered hydration for dewy finish.

Who is this for: ludient Radiance Glass Serum is built for anyone seeking a concentrated brightening step—ideal for people with dull or uneven complexions who want a dewy, refined finish. It suits those familiar with active serums and willing to patch-test higher-strength formulas; novices should introduce it gradually and always pair daytime use with sunscreen.
