High-potency Vitamin C serum for brighter, firmer, smoother skin

The Potent-C Power Serum delivers a breakthrough vitamin C treatment with 20% THD Ascorbate—an ultra-stable form of vitamin C claimed to be up to 50 × more effective than traditional ascorbic acid. This rich serum is further boosted with 3% Vitamin E and 2% Ferulic Acid, forming a synergistic antioxidant complex to target dullness, uneven tone, visible fine lines and loss of firmness. The silky fluid texture absorbs swiftly and leaves skin feeling renewed, while key botanical extracts provide a comforting, skin-reviving experience. With consistent use, skin appears visibly brighter, more even and uplifted.

From the advanced skincare line by Peter Thomas Roth, this serum is crafted for all skin types—normal, dry, combination or oily—and especially suited for those concerned with visible signs of ageing such as uneven texture, loss of elasticity, and shadowed or uneven skin tone. The formula deploys a concentrated dose of THD Ascorbate (20%) to help visibly defy seven signs of ageing—fine lines, wrinkles, uneven tone, loss of brightness, loss of firmness, uneven texture and dehydration. The inclusion of Vitamin E and Ferulic Acid supports antioxidant protection and enhances the longevity of the vitamin C performance. Ideal for both morning and evening routines, this serum can serve as a cornerstone for a firming-brightening skincare regimen.

Who it’s best for: Anyone concerned with dullness, uneven tone, early fine lines or loss of firmness who wants a potent vitamin C solution.
What makes it different: A clinically-strength serum featuring 20% THD Ascorbate plus Vitamin E & Ferulic Acid, delivering brightening and firming benefits in one step.

How To Use Potent-C Power Serum

Apply 1–2 pumps to clean, dry face and neck.
Use morning and night for best results.
Follow with your moisturizer and eye cream as needed. (No ramp-up required as product is formulated for all skin types.)

FAQs

Can I use this while pregnant or nursing?
The brand does not provide explicit guidance for use during pregnancy or nursing; please consult your physician before use.

Can I use this with retinol/retinal/acid exfoliants?
Yes — this serum can be used in tandem with retinol or acid treatments, though you may want to apply the vitamin C serum first, then wait 5-10 minutes before applying more potent actives.

Is it suitable for sensitive skin?
Yes — the formula is described as suitable for all skin types including sensitive; however, because it contains high-strength actives (20% vitamin C), a patch test is recommended for users with very reactive skin.

How long until I see results?
Visible improvements in brightness and texture may begin within one use; users in a 4-week study reported improvement in wrinkles, firmness and tone.

Can I use it around the eyes?
The brand does not specify use under the eyes; apply only to face and neck, and avoid lash line or direct eye contact.

Storage and shelf life?
Store in a cool, dry place out of direct sunlight; once opened, best results are achieved within 12 months (per standard skincare guidance, though brand does not specify a separate shelf-life).
