Obagi Rebalance Skin Barrier Cream Review: Postbiotic Moisturiser for Barrier Support
The Verdict
Rebalance earns its place as a barrier-recovery step rather than an everyday moisturiser: the postbiotic, ceramide and niacinamide combination is well suited to skin that's sensitised, reactive or recovering from actives and in-clinic procedures, and the lightweight gel-crème texture makes it easy to layer under other products. It's not designed to replace a richer daily moisturiser for skin that isn't currently struggling — for that, the standard Obagi Hydrate range or Hydrate Luxe are the better starting point, and the two ranges can be combined for more compromised skin.
Obagi Rebalance Skin Barrier Cream | Postbiotic Moisturiser | 48g
£100.00
Obagi Rebalance Skin Barrier Cream is a lightweight, 48g postbiotic moisturiser built around Obagi's BarrierPlex™ Technology — postbiotics, a triple ceramide complex, niacinamide and squalane — to help improve the appearance of a compromised or reactive skin barrier. Obagi positions it for all skin types as a recovery step for skin sensitised by peels, retinoids, AHAs or BHAs, rather than a replacement for a standard daily moisturiser.
What is Obagi Rebalance Skin Barrier Cream?
Rebalance sits apart from the rest of the Obagi Hydrate family by leading with a microbiome-focused, postbiotic formula rather than a purely hydrating one. The core technology, which Obagi calls BarrierPlex™, combines Lactobacillus Ferment (a postbiotic — a beneficial byproduct of probiotic fermentation) with a triple ceramide complex (Ceramide NP, AP and EOP), phytosphingosine, niacinamide and squalane, alongside soothing extracts including bisabolol, allantoin and oat kernel flour. The product comes in an airless pump bottle, dispensing a lightweight gel-crème texture designed to absorb quickly rather than sit on the skin.
Obagi's own description cites an in-house 2022 bio-instrumentation study (data on file at Obagi Cosmeceuticals LLC). We haven't repeated the specific percentage results from that testing here, as no independently published source was available to verify them.

Key ingredients
Lactobacillus Ferment (postbiotic)
Postbiotics are the beneficial byproducts of probiotic fermentation, increasingly used in skincare aimed at supporting the skin's own microbiome balance. Rebalance pairs Lactobacillus Ferment with Tetraselmis Suecica Extract (a marine algae) for its antioxidant content and its role in helping calm and hydrate stressed skin.
[[PROTECTED_93]], phytosphingosine and [[PROTECTED_94]]
Ceramides make up a significant part of the skin's own barrier structure, and this formula uses three named types (NP, AP and EOP) alongside phytosphingosine and cholesterol to mirror the skin's natural lipid composition — one of the more well-established mechanisms here, independent of Obagi's own study data. Niacinamide (vitamin B3) supports the skin's own ceramide production, and squalane is a lightweight emollient added for hydration without a heavy after-feel.
Who is it suitable for?
- Skin that's currently sensitised, reactive or compromised — for example after peels, retinoids, AHAs/BHAs or in-clinic procedures
- Those prone to redness, tightness or irritation who want a lightweight, non-greasy layering step
- Combination or oily skin that finds richer barrier creams too heavy
- Anyone already using an Obagi Nu-Derm or active-ingredient routine, using Rebalance as a soothing companion product
It's less suited to anyone simply wanting a standard everyday moisturiser — the standard Obagi Hydrate Facial Moisturiser or the richer Obagi Hydrate Luxe are the more general-purpose picks; Obagi notes the two ranges can be layered (Rebalance first, then Hydrate) for more compromised skin.
How to use Obagi Rebalance Skin Barrier Cream
- Cleanse first, and apply any treatment serums or actives before this product.
- Dispense 2–4 pumps onto fingertips and apply morning and evening, or as needed.
- In the morning, follow with sunscreen; it can be layered under other Obagi products.
- For post-procedure skin, Obagi suggests applying more liberally, and following your practitioner's specific aftercare instructions rather than general guidance.

Frequently asked questions
What is a postbiotic moisturiser?
It uses ingredients derived from the fermentation of beneficial bacteria — the byproducts, not live bacteria — to help support the skin's own microbiome balance. In Rebalance, that's Lactobacillus Ferment, combined with ceramides and niacinamide for broader barrier support.
Can I use Obagi Rebalance with my retinoid products?
Yes. Obagi positions it as a companion for skin using retinoids, AHAs, BHAs or other actives — apply your treatment first, then Rebalance afterwards to help soothe and support the barrier.
How does Obagi Rebalance differ from Obagi Hydrate?
Rebalance is built around postbiotic, barrier-recovery ingredients, while the standard Obagi Hydrate Facial Moisturiser and richer Obagi Hydrate Luxe focus on everyday or overnight moisturisation. Obagi suggests Rebalance first, then Hydrate, for more compromised skin.
Can I use Obagi Rebalance after professional treatments?
Obagi positions it as a post-procedure comfort step, citing an internal four-week evaluation. We haven't repeated Obagi's specific result figures here, as no independently published source was available to verify them — always follow your practitioner's own aftercare instructions instead.
Is Obagi Rebalance fragrance-free?
