Peter Thomas Roth Vitamin C Brightening Moisturizer — 10% THD Ascorbate Lightweight Gel-Cream, Hydrating & Anti-Aging

Potent-C Brightening Vitamin C Moisturizer is a lightweight antioxidant gel-cream that uses 10% THD ascorbate plus supportive actives to brighten skin, reduce the appearance of fine lines, and lock in hydration.

This moisturizer combines a stable, high-potency form of vitamin C (10% THD ascorbate) with complementary antioxidants and hydrators to target uneven tone, dullness, and signs of aging without heavy residue. The formula pairs vitamin E and ferulic acid for antioxidant synergy, while a Superfood Complex and essential minerals help defend against environmental stressors. Moisture-binding ingredients like hyaluronic acid and Trimoist KMF keep skin plumped and comfortable for up to 24 hours.

How quickly will I notice brighter-looking skin?

Visible changes depend on your skin and routine, but many users report improved radiance within several weeks of consistent use. The high-potency THD form of vitamin C is designed for effective delivery, and antioxidant partners help protect and enhance brightness over time.

• Contains 10% THD ascorbate for more efficient vitamin C delivery.
• Includes 3% vitamin E and ferulic acid to boost antioxidant protection.
• Antioxidant Superfood Complex supports skin defense against environmental damage.
• Expect gradual improvement in tone and brightness with regular application.

Will this moisturizer help with fine lines, firmness, and texture?

The formula targets multiple visible aging concerns through a combination of actives that hydrate and support skin structure. Hydrators and peptide-like ingredients plump the look of lines, while antioxidants and minerals address environmental factors that contribute to loss of firmness and texture irregularities.

• Hydration from hyaluronic acid and Trimoist KMF helps smooth fine lines.
• Ceramide NP, hydrolyzed collagen, and elastin support the skin’s moisture barrier and appearance.
• Vitamins A, C, B3 and minerals like zinc and calcium help maintain skin resilience.
• Suitable for improving uneven texture when used consistently.

Can I use this in the morning and at night with other actives?

This lightweight gel-cream is formulated for both AM and PM use; in the morning it pairs well with sunscreen to protect freshly brightened skin. Because it contains a stable vitamin C derivative and antioxidant boosters, it usually layers well with retinoids or exfoliating acids, but introduce combinations gradually to monitor tolerance.

• Use in the morning under SPF to maximize antioxidant protection.
• Compatible with most serums and creams—add potent actives slowly.
• Patch-test when combining with strong exfoliants or retinoids.
• Non-greasy texture suits layering in multi-step routines.

How does the product lock in moisture for up to 24 hours?

Moisture retention comes from humectants, barrier-reinforcing lipids, and film-forming ingredients that reduce water loss. These components work together to attract water, strengthen the skin’s outer layer, and help skin hold hydration across the day.

• Hyaluronic acid binds moisture to the skin surface for immediate plumpness.
• Ceramide NP supports the skin’s barrier to prevent transepidermal water loss.
• Trimoist KMF provides long-lasting hydration and skin comfort.
• Hydrolyzed collagen and elastin enhance surface smoothness and resilience.

Who is this for: Ideal for anyone seeking a potent, daytime-friendly vitamin C moisturizer that brightens and hydrates without heaviness. It suits normal to combination skin and those wanting antioxidant support against environmental stressors; if you have very sensitive skin, patch testing is recommended before full-face use.
