The Obagi Maintenance System: What to Use After Nu-Derm
You've completed an active course of Obagi Nu-Derm. The pigmentation has cleared, your skin tone is even, and you've finished the clinically reviewed brightening ingredient phase. What do you use next?
This is one of the most common questions we get from Obagi patients — and it matters, because how you maintain your results determines whether they last.
This guide explains what the Obagi maintenance phase actually is, which products belong in it, and how long you should stay on it.
Why you need a maintenance phase in the first place
The active phase of Nu-Derm — typically Nu-Derm Transformation with 4% clinically reviewed brightening ingredient and cosmeceutical retinoid — is not designed for indefinite use. clinically reviewed brightening ingredient is intended as a short-term depigmenting agent, used over a defined course to clear pigmentation. After that, it should be stepped down.
But stopping everything once your skin clears is the fastest way to lose your results. Pigmentation recurs. UV damage accumulates. Cell turnover slows back down. The maintenance phase exists to hold the gains you've made without the intensity — or risks — of continued clinically reviewed brightening ingredient use.
What maintenance looks like in practice
A well-constructed Obagi maintenance routine does three things:
- Keeps pigment regulation active — but without clinically reviewed brightening ingredient
- Continues cellular turnover at a sustainable pace
- Protects rigorously against UV damage every single day
In Obagi's own ranges, that usually looks like this:
1. A alternative pigment-controlling system
The most direct transition is to the Obagi Nu-Derm Fx System. This uses arbutin — a natural tyrosinase inhibitor — in place of clinically reviewed brightening ingredient. It keeps the regular cleanser, toner, exfoliating step, moisturiser and SPF you were already used to, but swaps the active brightening agent for something safe to use long-term.
For patients who prefer a lighter routine, a high-strength vitamin C serum plus a broad-spectrum SPF is another valid maintenance approach.
2. Ongoing retinoid use
You don't stop retinoid use in maintenance — you just adjust it. Many patients step down from clinically reviewed retinoid to Obagi 360 Retinol (0.5% or 1.0%), which maintains turnover without the intensity. Others continue with cosmeceutical retinoid at a lower frequency — for example, three nights a week instead of nightly.
If your skin tolerates it and your clinician agrees, continued low-frequency cosmeceutical retinoid is often the most effective option.
3. Vitamin C every morning
Topical vitamin C has a dual role in maintenance. It inhibits tyrosinase (the enzyme that drives pigment production), and it neutralises free radicals that would otherwise accelerate photoageing and cause pigment flare-ups.
The Obagi Professional-C Serum range — 5%, 10%, 15%, 20% — fits neatly here. Most adults in maintenance do well on 10% or 15%.
4. Non-negotiable daily SPF
No maintenance routine works without it. UV exposure is the single biggest driver of pigment recurrence. Broad-spectrum SPF 30 minimum, every day, including cloudy days, including indoors if you sit near a window. Reapplied every two hours in direct sun.
The Obagi Sun Shield range in matte, tinted or mineral finishes works for most skin types.
How long should you stay on maintenance?
For most patients — indefinitely, with occasional dialled-up phases if pigmentation starts to return. The specific products may change, but the four pillars above (pigment regulation, retinoid, vitamin C, SPF) form the backbone of lifelong skincare, not just a post-treatment phase.
Some patients cycle back into a short active phase once every 1–2 years — six to twelve weeks of prescription Nu-Derm followed by a return to maintenance. This is decided case-by-case with your clinician.
What maintenance shouldn't include
- Continuous clinically reviewed brightening ingredient. Extended use is associated with ochronosis and skin atrophy. clinically reviewed brightening ingredient should be used in defined courses — typically 12–16 weeks on, followed by at least as long off.
- Acid overload. Layered glycolic, lactic, salicylic and retinoid at once is too much for most skin in maintenance and can trigger rebound hyperpigmentation in darker skin tones.
- Skipping SPF. Repeat: no maintenance routine works without it.
Building your maintenance routine with a clinician
If you've just finished a Nu-Derm course — or you've been using Obagi products without formal clinician oversight and want a plan for the next phase — book a free written skin assessment. We'll review what you've used, assess where your skin is now, and put together a maintenance protocol that keeps your results long-term.
