Peter Thomas Roth Potent-C Brightening Vitamin C Moisturizer — 10% THD Ascorbate, Hydrating Gel-Cream

This serum-texture moisturizer blends an advanced, oil‑stable form of vitamin C with complementary antioxidants, peptides, and hydrators to address uneven tone, dullness, and moisture loss. The formula pairs 10% THD ascorbate (a potent vitamin C derivative) with 3% vitamin E and ferulic acid for stabilized antioxidant protection, while a superfood complex and skin‑plumping ingredients support smoother, more luminous-looking skin with daily use.

How does this moisturizer brighten and even skin tone?

The core brightening action comes from THD ascorbate, a highly active vitamin C derivative that penetrates skin more effectively than standard ascorbic acid. Vitamin E and ferulic acid stabilize the vitamin C and broaden antioxidant coverage to help maintain visible improvements in tone and radiance.

• 10% THD ascorbate for potent brightening performance
• 3% vitamin E plus ferulic acid to stabilize and boost antioxidant effect
• Antioxidant Superfood Complex with kale sprouts and olives to support skin resilience

Will it hydrate and plump without feeling heavy?

The gel‑cream texture is engineered to deliver lasting moisture without greasiness. Hyaluronic acid, ceramide NP, hydrolyzed collagen and elastin add immediate plumping and barrier support, while Trimoist KMF helps retain hydration for up to 24 hours in many users.

• Hyaluronic acid binds moisture to the skin surface for instant plumpness
• Ceramide NP strengthens the skin barrier to prevent moisture loss
• Collagen and elastin fragments help improve the look of texture and firmness

How does the antioxidant blend protect and support aging skin concerns?

Beyond brightening, the formulation combines vitamins and minerals to defend against environmental stressors that accelerate visible aging. Calcium, zinc, vitamins A, C and B3 plus the antioxidant complex work together to maintain skin radiance and support a smoother surface appearance over time.

• Ferulic acid enhances stability and efficacy of antioxidant ingredients
• Vitamin A and B3 help address uneven texture and tone
• Minerals like zinc and calcium assist overall skin health and resilience

How should I incorporate it into my daily routine?

Use this moisturizer after cleansing and applying serums; it complements both morning and evening regimens. In the morning, follow with sunscreen to protect the brightening effects; in the evening, it layers well under targeted treatments or heavier creams if extra hydration is needed.

• Apply a pea-sized amount to face and neck after serums
• Use daily; pair with SPF in the morning for best results
• Safe to layer with most active serums—patch test new combinations

Who is this for: Peter Thomas Roth Potent‑C Brightening Vitamin C Moisturizer suits people seeking a non-greasy, science-driven day and night moisturizer that targets dullness, uneven tone, early signs of aging, and dehydration. It's appropriate for most skin types looking for a potent vitamin C option that also offers multi‑ingredient hydration and antioxidant support; those with extremely reactive skin should patch test first or consult a skincare professional.
