Who it's for

This lotion suits people who already tolerate mild chemical exfoliation and want to fold it into a morning routine rather than layering yet another product. It's aimed at those dealing with uneven tone, rough texture, or early signs of photoageing who also want a lightweight moisturiser underneath — rather than a heavier night cream repurposed for daytime.

Who should skip it

If you're new to acids, already using a leave-on exfoliant elsewhere in your routine, or have reactive, compromised skin, this is not the place to start. The combination of daily glycolic acid with vitamin C can be more than some skin can handle straight away, and stacking it with other actives (retinoids, additional AHAs/BHAs) increases the risk of irritation. If you are pregnant, breastfeeding, or unsure whether an active-led routine is appropriate for you, contact our team before starting.

How to use it

Apply in the morning after cleansing and toning, to dry skin, as the third step in the Obagi-C Rx System. A thin, even layer is enough — this is a lotion, not a rich cream, and it's designed to absorb quickly rather than sit on the surface. Because it contains a leave-on acid, a broad-spectrum SPF over the top isn't optional; skip it and you're undoing the point of the product. Some mild tingling on first use is expected as skin adjusts; if irritation persists rather than settling, scale back frequency and speak to our team.

The ingredients that matter

The headline active is Glycolic Acid at 4% — a small-molecule AHA that works on the skin's surface to loosen the bonds between dead skin cells, helping improve the appearance of rough texture and dullness over time. It's a moderate, daily-use strength rather than an intensive peel-level dose, which is what makes daily wear realistic for most users who've built up some tolerance.

Sitting alongside it is Ascorbyl Glucoside, a stabilised, water-soluble form of vitamin C. It's gentler and more shelf-stable than pure ascorbic acid, which suits a formula that's already carrying an acid — but it also tends to be a milder performer, so don't expect the same intensity as a dedicated high-strength vitamin C serum.

Hydration comes from Sodium Hyaluronate and squalane, while Bisabolol (derived from chamomile) and Tocopheryl Acetate (Vitamin E) are included to help calm and support the skin barrier while the glycolic acid does its work. It's a sensible pairing on paper — soothing agents alongside an exfoliant — though it doesn't eliminate the need to introduce the product gradually.

Where it fits in the Obagi-C Rx System

This lotion is the third step of the Obagi-C Rx System, typically following the Obagi-C Fx C-Clarifying Serum and a toning step, then finished with sunscreen — our Obagi Sun Shield Mineral SPF50 review covers a suitable option. For the wider Obagi range, see our Obagi brand overview.

Verdict

The Obagi-C Fx Exfoliating Day Lotion earns its place for people who want daily mild exfoliation and lightweight hydration without adding a separate step. It's not a product to introduce cold into a sensitive or acid-naive routine, and it works best as part of the full Obagi-C Rx System rather than mixed freely with other actives. For the right skin, it's a tidy way to get texture, tone and hydration handled in one morning move — provided SPF is non-negotiable on top.

Safety, sensitivity and pregnancy

Mild tingling on first use is common with glycolic acid formulas and usually settles with continued use; persistent irritation is a reason to pause and seek advice rather than push through. If you're pregnant or breastfeeding, please contact our team for advice before use.
