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

Jack Black Brightening Booster Vitamin C Serum is a lightweight, hydrating antioxidant serum featuring 10% THD-Ascorbate to brighten skin and help even complexion tone.

This multitasking serum combines a highly stable form of vitamin C with hydrating ingredients and protective botanicals to support brighter-looking skin and a more uniform tone over time. Formulated to be gentle and free of parabens and harsh surfactants, the product is dermatologist tested and largely vegan-friendly. Its clean formulation also includes green microalgae to address modern stressors like blue light exposure.

How does this serum fit into a daily skincare routine?

Apply the serum after cleansing and before moisturizer to let its concentrated actives absorb into skin. Use it in the morning for antioxidant protection and in the evening to support nightly renewal; always follow with sunscreen during daytime. A little typically goes a long way, so one to two drops is often sufficient to cover the face.

• Use after cleansing and toning, before creams or oils
• Suitable for AM and PM; pair with SPF for daytime
• Dispense 1–2 drops and pat gently into skin
• Compatible with most serums and moisturizers

What makes 10% THD-Ascorbate different from other vitamin C types?

THD-Ascorbate is a stable, oil-soluble derivative of vitamin C designed to resist oxidation and penetrate the skin effectively. At 10% concentration it provides a balance of potency and tolerance, aiming to brighten the look of skin and help even discoloration without the immediate irritation some forms of vitamin C can cause.

• Stable formulation reduces premature degradation
• Oil-soluble for better skin delivery and feel
• 10% concentration balances efficacy and gentleness
• Suitable for sensitive skin when used as directed

Which additional ingredients support the serum’s effect?

Alongside THD-Ascorbate, the formula includes hydrating elements and green microalgae to help shield skin from environmental stressors like blue light. These supporting ingredients help maintain skin moisture and contribute to an overall brighter-looking complexion when used consistently.

• Green microalgae helps defend against digital light stressors
• Hydrators lock in moisture for smoother texture
• Free of parabens and harsh surfactants for gentler use
• Dermatologist tested and cruelty-free

How quickly will I notice results and how should I store the serum?

Visible improvements in tone and brightness can vary by individual, with many users reporting subtle changes within a few weeks and more noticeable results after consistent use for several months. Store the serum in a cool, dry place away from direct sunlight and tightly reseal the cap to preserve the stability of the vitamin C derivative.

• Some users see early brightening within weeks
• Best results with regular use over months
• Keep bottle capped and stored out of sunlight
• Room temperature or cooler storage helps longevity
