Jack Black Vitamin C Brightening Booster Serum, 1 oz — 10% THD‑Ascorbate, lightweight hydrating

Jack Black Brightening Booster is a lightweight, hydrating Vitamin C serum formulated with 10% THD‑Ascorbate to help even tone, reduce the look of aging, and shield skin from blue‑light stressors.

This concentrated 1 oz serum blends a stabilized, oil‑soluble form of Vitamin C with green microalgae and complementary antioxidants to support brighter, more even skin over time. The fast‑absorbing texture layers easily under moisturizers or sunscreen, and the formula is dermatologist tested, paraben‑free, cruelty‑free, and made in the USA. It’s designed to work into daily routines for visible improvement in radiance and texture when used consistently.

How does the Vitamin C in this serum brighten skin tone?

Jack Black uses 10% THD‑Ascorbate, a stable, oil‑soluble Vitamin C derivative that penetrates skin effectively and supports gradual brightening with continued use. Unlike unstable ascorbic acid, THD‑Ascorbate resists oxidation, helping the product maintain potency longer.

• Contains 10% THD‑Ascorbate for consistent antioxidant activity
• Oil‑soluble delivery improves skin absorption
• Formulated to resist breakdown from light and air
• Used daily for progressive evening of discoloration

Will this serum hydrate without feeling greasy?

The Brightening Booster is formulated to hydrate while remaining lightweight and fast‑absorbing, making it suitable under creams, sunscreen, or makeup. Its balance of humectant and emollient elements supports moisture without leaving a heavy residue.

• Light, non‑oily texture that layers well
• Designed for morning and evening application
• Absorbs quickly so makeup won’t slide
• Helps skin look smoother and more supple

How does the serum protect skin from environmental stress like blue light?

Green microalgae in the formula helps defend against oxidative stress associated with visible light exposure, while Vitamin C offers broad antioxidant support. Together they help buffer skin from daily environmental aggressors that can accelerate visible aging and uneven tone.

• Green microalgae contributes protection against blue‑light effects
• Antioxidant blend neutralizes free radicals
• Daily use supports resilience to environmental stress
• Pair with sunscreen for comprehensive daytime protection

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

The formulation is dermatologist tested and free of parabens and harsh surfactants, minimizing common irritants. While many with sensitive or oily skin tolerate this lightweight serum, patch testing is recommended before full application.

• Dermatologist tested and largely free of common irritants
• Most of Jack Black’s line is vegan and free of artificial colorants
• Non‑heavy finish reduces pore‑clogging risk
• Start with every‑other‑day use to assess tolerance

Who is this for: Jack Black Brightening Booster Vitamin C Serum is intended for anyone looking to boost radiance, even out discoloration, and add antioxidant protection to their daily regimen. It’s a practical choice for men and women who want a stable, concentrated Vitamin C treatment that layers easily under other products, and for those seeking a formula without parabens, harsh surfactants, or animal testing. Ideal for users committed to consistent application to see progressive improvements in skin tone and texture.
