Vitamin C may be your secret weapon if you want to elevate your skincare regimen and rediscover skin that glows with vitality. At KAST Medical Aesthetics in Cheshire, our Obagi CRx System products harness the transformative potential of stabilised vitamin C to revitalise ageing, dull, or uneven skin, without the fluff.
Let’s examine this powerhouse ingredient in depth and uncover why Obagi CRx is making waves among men and women aged 35-75 who are seeking real, visible results.
What Is the Obagi CRx System and How Does It Work?
The Obagi CRx System is a clinically backed, prescription-only skincare protocol formulated to correct early signs of skin ageing. It combines L-ascorbic acid (Vitamin C) with 4% hydroquinone, creating a dual-action regimen that brightens the complexion while targeting hyperpigmentation, sun damage, and uneven skin tone.
This system doesn’t just sit pretty on your shelf; it penetrates deeply, working at a cellular level to correct damage and maintain long-term skin health. Over time, this leads to firmer, clearer, and more luminous skin.
Why Vitamin C Is Essential in Your Skincare Routine
What does Vitamin C do for the skin? Think antioxidant protection, collagen synthesis, and skin brightening, all in one. As we age, oxidative stress (from sun exposure, pollution, and lifestyle) breaks down collagen and accelerates skin dullness. Vitamin C neutralises these free radicals while also boosting the skin’s natural repair processes.
In Obagi CRx, L-ascorbic acid is used in its purest, most potent form. This ensures maximal absorption and activity, something many over-the-counter brands simply cannot match.
Obagi CRx vs Over-the-Counter Vitamin C Products: What’s the Difference?
Not all Vitamin C serums are created equal.
The Obagi CRx System features a potent 10% or 20% concentration of L-ascorbic acid, clinically stabilised for deeper dermal delivery. Over-the-counter products often contain lower concentrations or less effective derivatives (like magnesium ascorbyl phosphate), which don’t absorb well or oxidise rapidly on the skin.
What’s more, Obagi CRx pairs Vitamin C with hydroquinone to target pigmentation at the root. Most high-street products simply don’t have this level of synergy, or prescription strength.
Who Is Obagi CRx Best For?
This system is designed for:
- Men and women aged 35+ who are beginning to see signs of sun damage or fine lines
- Those with melasma, age spots, or dull, uneven tone
- Patients seeking a prescribed skincare plan with proven results
It’s especially suitable for those who are new to medical-grade skincare and want to make a visible change without jumping into injectables.
How to Use the Obagi CRx System for Maximum Results
The CRx System includes a gentle cleanser, a C-Clarifying Serum, Clear FX, Exfoderm, and Sun Shield SPF 50. Most patients begin with a morning application of Vitamin C serum, followed by hydroquinone and SPF. Evening use typically involves deeper exfoliation and repair.
To truly optimise results:
- Apply Vitamin C in the morning to neutralise oxidative stress
- Avoid mixing with retinol, benzoyl peroxide, or AHAs at the same time (What cannot mix with Vitamin C? These are the usual culprits)
- Always follow with SPF to prevent further pigmentation
What Results Can You Expect from Obagi CRx?
Expect a progressive transformation.
Within 4-6 weeks, skin typically looks brighter and more refined. By 12 weeks, many patients report:
- Reduced pigmentation and age spots
- A more even skin tone
- A boost in natural luminosity
- A softening of fine lines
These are not fleeting effects; they’re cumulative. The longer you use the system under professional guidance, the more profound the results.
Common Side Effects and What to Expect in the First Few Weeks
Don’t be alarmed if your skin feels a little tingly at first; this is normal.
In the initial phase, you may notice:
- Mild redness
- Light peeling or dryness
- A sensation of warmth when applying the Vitamin C serum
These effects usually subside as your skin adjusts. At KAST Medical Aesthetics, our team is always available to offer tailored guidance and tweak your protocol if necessary.
Can Obagi CRx Help with Pigmentation, Dullness, and Early Ageing?
Yes, and that’s precisely what it’s designed for.
Obagi CRx tackles melanin production at the source, fading stubborn pigmentation from sun damage or hormonal changes. It also enhances skin cell turnover, which is often sluggish in ageing skin, restoring glow and texture.
If you’ve tried everything from supermarket scrubs to influencer-recommended potions, this is the professionally guided solution you’ve been waiting for.
How Long Should You Stay on the Obagi CRx System?
While you’ll see early results, long-term use brings sustained improvement.
Most patients use Obagi CRx for 12–16 weeks before transitioning to a maintenance regimen. That might include continuing the Vitamin C serum daily, yes, you can use Vitamin C every day on your face, and in fact, it’s encouraged, along with other Obagi favourites prescribed by your clinician.

What Percentage of Vitamin C Is in Obagi CRx?

Is Obagi CRx Safe for Sensitive Skin?
Yes, but with caution.
Those with sensitive skin should begin with the 10% serum and introduce it slowly. A professional consultation is essential to avoid overstimulation.
