Meet the revamped Prescription Vitamin C Serum 15%: Your secret weapon for radiant skin

Dull skin, dark spots or the first signs of ageing? For years, vitamin C has been the holy grail of skincare when it comes to achieving a clear and even complexion. Prescription Skincare is now making a big splash with the launch of a brand-new product: the Vitamin C Serum 15%. This powerful serum replaces the well-known Ascorbic Acid, but has been taken to an even higher level in terms of formula, stability and effectiveness.

In this blog, you’ll find out everything you need to know about this new product, why it’s an absolute must-have in your skincare routine, how to use it and how it differs from the previous product.

What does the 15% Vitamin C Serum do for your skin?

The Prescription Vitamin C Serum 15% is an advanced serum specially formulated to give your skin an instant, radiant glow whilst providing long-lasting protection. The unique, improved formula combines a powerful 15% concentration of vitamin C with strengthening antioxidants.

Here’s what the serum does for your skin:

  • Reduces dark spots and minor scars: Helps visibly lighten stubborn dark spots and marks left by spots or minor scars.

  • Stimulates collagen production: Supports the skin’s firmness and elasticity, helping to reduce fine lines.

  • Powerful antioxidant protection: Forms a shield against harmful external influences, such as UV radiation and air pollution.

  • Instant glow: Instantly gives tired, dull skin a fresh, healthy appearance.

The 3 key ingredients highlighted

The power of this serum lies in the synergy between three carefully selected ingredients:

  1. Vitamin C (15% in the form of ascorbic acid): A powerful antioxidant that protects the skin, stimulates collagen, brightens pigmentation and provides that ultimate glow.

  2. Ferulic acid: A plant-based antioxidant extracted from the cell walls of rice and oats. It neutralises external damage and specifically supports the action and stability of vitamin C.

  3. Vitamin E (in the form of tocopherol): A powerful ally that enhances the action of vitamin C and ferulic acid. In addition, vitamin E specifically focuses on restoring and maintaining a strong skin barrier.

How it works & Results: How to tackle pigmentation effectively

Pigmentation is often caused by sun exposure, inflammation or hormonal factors. Without a targeted approach, discolouration will remain visible.

Combining the right Prescription products helps to effectively even out the complexion:

  • Glycolic Acid removes the top layer of dead skin cells, leaving the skin looking fresher and allowing active ingredients to penetrate deeper.

  • Vitamin C Serum 15% supports the lightening of pigmentation and contributes to a more even complexion.

  • The Edelweiss Cream keeps the skin comfortable and soothed during the renewal process.

  • With consistent SPF50 protection, you can prevent UV radiation from triggering new pigmentation or deepening existing spots.

The result: A brighter, more even complexion with a fresh, healthy glow.

Why is this serum essential to your skincare routine?

Free radicals (caused by sunlight, stress and air pollution) break down the collagen in your skin every day, leading to premature ageing and dark spots. A day cream alone is often not enough to combat this. A high-quality vitamin C serum with 15% active ingredients penetrates deeper into the skin, repairs accumulated damage, evens out the complexion and ensures your skin looks fresh, firm and radiant day in, day out.

Your complete Prescription routine for day and night

To get the most out of your skincare, use the products according to the targeted skin concern routine below:

Morning routine

  1. Edelweiss Cleanser: Start your day with a gentle cleanse to remove impurities and excess sebum without disrupting the skin barrier.

  2. Vitamin C Serum 15%: Apply the serum undiluted to clean skin for an intense boost, or mix a few drops into your moisturiser.

  3. Edelweiss Cream: Hydrates, nourishes and keeps the skin feeling comfortable.

  4. SPF50 Drops: Provides optimal protection against harmful UV rays to prevent pigmentation spots. (Tip: you can also mix the SPF50 Drops directly with the Edelweiss Cream!)

Evening routine

  1. Edelweiss Cleanser: Thoroughly cleanse the skin of make-up, SPF and daily impurities.

  2. Glycolic Acid (2–3 evenings a week): Exfoliates the skin, removes dead skin cells and stimulates cell renewal. Gradually build up your use of Glycolic Acid, depending on your skin’s tolerance.

  3. Edelweiss Cream: Nourishes and repairs the skin overnight.

The difference: Vitamin C Serum 15% & Ascorbic Acid

Curious to know what has changed compared to our previous formula with Ascorbic Acid?

  • Enriched formula: Whereas the old product focused purely on vitamin C on its own, the new Vitamin C Serum 15% is enriched with a powerful blend of ferulic acid and vitamin E.

  • Enhanced efficacy & stability: The addition of ferulic acid and vitamin E not only supports the effectiveness of the vitamin C, but also ensures the formula remains more stable and acts even more effectively on pigmentation and signs of ageing.

  • Optimal skin barrier: The addition of tocopherol (vitamin E) places greater emphasis on repairing and maintaining the skin barrier, making the serum feel more comfortable whilst simultaneously soothing and nourishing the skin.

Frequently Asked Questions about Prescription Vitamin C 15%

Certainly, the formula has been developed to suit most skin types. Do you have sensitive skin? If so, we recommend gradually introducing the serum over the first few weeks by mixing it with your favourite moisturiser, or testing it on a small patch of skin first.

Yes! Although vitamin C is a favourite for the morning because of its protective effects against UV rays and free radicals during the day, it’s also perfectly fine to apply it in the evening. In fact, your skin will benefit most from its restorative properties whilst you sleep.

If you use the serum in the morning, we definitely recommend it! Vitamin C protects your skin against free radicals, but it is no substitute for sun cream. By finishing off your morning routine with an SPF, you’ll provide your skin with the best possible protection against new pigmentation marks.
Yes, you can, but spread them out over the course of the day and night to avoid overloading your skin. Use the Vitamin C Serum every morning and save the Glycolic Acid for the evening (2 to 3 times a week). That way, you’ll get the most out of both active ingredients without irritating your skin.
