Vitamin C Serum 25

$ 63.00 Regular price $ 70.00
A potent Vitamin C daytime serum that forcefully fends off free radicals, while helping to prevent and correct the signs of aging and sun damage. This skin-perfecting powerhouse helps significantly increase collagen production to dramatically firm and strengthen skin, while visibly evening out tone and brightening the complexion. Proprietary silanol technology rejuvenates skin’s other structural components to improve elasticity and help prevent lines and wrinkles. Advanced hydrators deeply moisturize to leave skin looking beautifully lifted, remarkably radiant and defended against environmental damage. 

In the morning apply to clean, dry skin on the face and neck. Follow with moisturizer and sunscreen and get ready to get glowing radiant skin.

Three forms of stabilized Vitamin C provide powerful antioxidant protection against environmental damage, while jump starting skin firming collagen production.

Exclusive Silanol Technology further stimulates collagen synthesis, while boosting skin’s metabolic functions and other structural components to improve elasticity and ward of lines and wrinkles.

Amino Acids help activate fibroblasts within the skin to build youthful, skin-densifying collagen and reduce the depth and intensity of fine lines and wrinkles.

Seaweed Extracts deliver meaningful moisturization, while further spurring collagen creation to noticeably boost elasticity and resilience for a marvelously toned and lifted look. Hyaluronic Acid attracts moisture into skin and helps keep it there -plumping up fine lines and wrinkles to diminish their appearance, while creating a firmer and dewy complexion.

Vitamin C Serum 25 FAQs

It contains a high concentration (25%) of 3-O Ethyl Ascorbic Acid, a stable and effective form of vitamin C that penetrates deeply to brighten, protect, and firm skin. It’s one of the most potent vitamin C serums available for at-home use.

  • Brightens skin tone and helps fade dark spots
  • Boosts collagen production for firmer, smoother skin
  • Protects against free radicals from UV rays and pollution
  • Improves texture and radiance
  • Hydrates and soothes with hyaluronic acid and botanical extracts

It’s best for normal, combination, oily, and mature skin. Those with sensitive skin may find it too strong and should start with a lower concentration vitamin C serum.

  • Apply a few drops to clean, dry skin once daily, preferably in the morning.
  • Follow with moisturizer and broad-spectrum SPF.
  • If irritation occurs, reduce to every other day.

It’s best to avoid layering strong actives (retinol, AHAs, BHAs) at the same time. Alternate use — vitamin C in the morning and retinol or exfoliants at night — for best results.

Because of the high vitamin C concentration, you may feel a mild tingling when first applying. This usually subsides as your skin builds tolerance. If redness or irritation persists, use less often.

No. Unlike pure ascorbic acid, 3-O Ethyl Ascorbic Acid is highly stable, which means it resists oxidation and stays effective longer. Store in a cool, dark place to maximize freshness.

Yes. Vitamin C Serum 25 is excellent for post-acne marks, uneven tone, and sun spots, helping to fade discoloration with consistent use.

It includes lavender, grapefruit, and geranium oils, which give it a subtle botanical scent. It also contains naturally occurring compounds like limonene, linalool, geraniol, and citral.

  • Radiance and hydration – within days
  • Smoother texture and glow – 2–4 weeks
  • Improvement in dark spots and firmness – typically 6–8 weeks of consistent use

Vitamin C Serum 25 pH Profile:~4.2*

The Vitamin C Serum 25 is formulated at a low acidic pH of 4.2 to optimize the performance of 25% 3-O-Ethyl Ascorbic Acid, a highly stable vitamin C derivative. At this level, the serum delivers strong antioxidant protection, helps brighten uneven tone, and supports collagen production, while soothing agents like hyaluronic acid and ergothioneine maintain hydration and comfort.

pH profile graphic for Vitamin C Serum 25
At 4.2, the Vitamin C Serum 25 is precisely balanced to deliver high-strength antioxidant and brightening benefits, while remaining stable and tolerable for most skin types.

Optimal pH Range: 3.8 – 4.5
Below 3.5 > Too acidic for daily serum use; may increase stinging and sensitivity.
3.8 – 4.3 > Peak zone for 3-O-Ethyl Ascorbic Acid activity; supports brightening and collagen stimulation.
Around 4.5 – 5.0 > Still effective, but with slightly less potency in brightening and antioxidant performance.
Above 5.5 > Vitamin C stability decreases; benefits may be reduced over time.

*Product pH may vary by ±0.2 due to normal manufacturing tolerance.

27 years of vitamin c serum use with success!

I am 67 years old and I have been using this since I was 40 when my dermatologist recommended it. When people ask me what I do to keep my skin looking so good, I attribute it to your vitamin c serum. I have never had any procedures done and I am grateful for your serum and highly recommend it.
