How to Layer Your Skincare at Night: Dr Bianca's ZO Routine Explained

How to Layer Your Skincare at Night: My ZO Routine Explained

It's the question I hear more than almost any other. People arrive at Wellface with a bathroom shelf full of good products and no clear idea of what goes on first, what goes on last, and whether they're accidentally cancelling one out with another. The truth is that the order you apply skincare in matters just as much as the products themselves. Get it right and each step supports the next. Get it wrong and even an expensive serum can end up sitting on top of your skin doing very little.

In my reel, I walk through a straightforward nighttime routine built around ZO Skin Health, the medical-grade range we use at the clinic. The logic is simple once you see it laid out. You clean the surface, you remove the dead cells that block absorption, you deliver your active ingredients, and then you seal everything in so your skin can repair overnight. Evening is the ideal time for this because your skin does most of its regenerative work while you sleep, and it isn't fighting sunlight, pollution or makeup.

What follows is my routine, step by step, with a bit more detail on why each stage earns its place. Think of it as a template rather than a rigid prescription. Not everyone needs every step every night, and the whole point of a doctor-led approach is that the routine bends to suit your skin rather than the other way around.

Why layering order actually matters

Skincare is absorbed in layers, and the general rule is to work from the thinnest, most active textures up to the richest, most occlusive ones. If you apply a heavy cream first, you effectively build a wall that your treatment serums then struggle to get through. Applying in the right sequence means the ingredients that need to reach deeper into the skin get their chance before anything seals the surface.

There's a second reason it matters, and it's about preparation. Actives like retinol and vitamin C work far better on skin that's genuinely clean and free of dead cell build-up. That surface layer of tired, flaky cells is one of the main reasons skin looks dull and feels rough, and it's also a physical barrier that slows down absorption. So the early steps of my routine aren't just about feeling fresh. They're clearing the runway so the actives can land.

Dry skin and rough texture, the two concerns this routine is aimed at, both respond well to this kind of structured approach. Dehydrated skin needs gentle exfoliation to lift the dull surface, then hydration properly locked in. Uneven texture and visible pores improve when cell turnover is encouraged and the skin barrier is kept strong. A well-ordered routine addresses both at once.

Step one: cleanse for a full sixty seconds

Everything starts with a clean canvas. I recommend starting on wet skin with a gentle cleanser, working it into a foam and massaging for a full sixty seconds before rinsing thoroughly. That minute matters more than most people realise. A quick ten-second splash barely lifts the day's makeup, sunscreen and grime, whereas a proper sixty-second cleanse gives the formula time to loosen and dissolve everything sitting on the surface.

The ZO Gentle Cleanser I reach for is designed to clean without stripping, which is exactly what you want as the foundation of a nighttime routine. Harsh, squeaky-tight cleansers can compromise the skin barrier and leave you drier than when you started. If you wear a lot of makeup or a heavy SPF, a double cleanse is worth considering, where the first pass removes the products and the second cleans the skin itself.

Rinse well and pat, don't rub, with a clean towel. You're now ready to prep the surface properly.

Step two and three: physical then chemical exfoliation

This is the part of the routine that clears away dead skin so your actives can work, and I use two complementary types of exfoliation.

The physical exfoliant

First comes a physical exfoliant, a polish or scrub such as ZO's Exfoliating Polish. These contain fine particles, in ZO's case magnesium crystals, that manually buff away the dead cells sitting on the surface. It's the immediate, tactile smoothing step, and it leaves skin feeling instantly softer. The key is a light touch. You're polishing, not scrubbing hard, and a gentle circular motion for a short time is plenty. Over-scrubbing is one of the more common ways people irritate their own skin without realising it.

The chemical exfoliant

Next comes a chemical exfoliant, which does a different job. Rather than buffing the surface, these use acids or enzymes to break down the bonds holding dead cells together so they shed more easily. ZO's exfoliating pads and peels fall into this category. Working the two together, physical then chemical, leaves the skin genuinely clean and receptive, which is why I describe it as being ready for your actives.

A word of realism here. You don't necessarily need both forms of exfoliation every single night, especially when you're also using retinol. Retinol is itself a powerful renewal ingredient, and stacking heavy exfoliation on top of it every evening can tip sensitive skin into irritation. Many people do best exfoliating a couple of times a week and letting the retinol do the heavy lifting on other nights. This is exactly the kind of thing a consultation helps you dial in, because the right frequency depends on how robust your skin is to begin with.

Step four: introducing retinol the sensible way

Retinol, a derivative of vitamin A, is one of the most researched and effective ingredients in skincare. It encourages cell turnover, supports collagen, refines texture and helps even out tone over time. It's the active most directly responsible for the smoother, brighter skin people are usually chasing when they build a routine like this.

I use the ZO Retinol Skin Brightener at 0.25%, which is the entry-level strength and the sensible place for most people to begin. The golden rule with retinol is to start low and slow. I suggest beginning with roughly once a week, then building to twice, then three times a week, and eventually to nightly use if and only if your skin tolerates it comfortably. There's no prize for rushing. Pushing too hard too soon is the classic mistake that leads to redness, flaking and dryness, which then puts people off retinol entirely.

Apply it to clean, dry skin, and use only a small amount, around a pea-sized quantity for the whole face. If you're brand new to retinol or your skin runs sensitive, applying a hydrator first can buffer the effect and make the introduction gentler. Some initial dryness or light flaking as your skin adjusts is normal and usually settles as your skin acclimatises. If irritation persists, the answer is to reduce frequency rather than abandon it altogether.

One important point that belongs with any retinol conversation: it makes your skin more sensitive to sunlight, so a broad-spectrum SPF every morning is non-negotiable while you're using it. That's true even in winter and even on cloudy days.

Step five and six: lock in hydration and treat the eyes

With your active applied, the final job is to seal everything in and support the skin barrier overnight. I finish with a hydrator, using a lightweight option in my demonstration while noting that richer, more nourishing textures are available for drier skin or colder months. This is where the layering principle pays off. By coming last, the moisturiser traps the active ingredients underneath and creates the conditions for your skin to repair while you sleep. It also cushions any potential dryness from the retinol, which is why pairing a good hydrator with retinol is standard advice.

If your skin is on the dry or dehydrated side, this is the step to be generous with. A more occlusive night cream helps prevent the trans-epidermal water loss that leaves skin looking tight and dull by morning. Oilier or combination skins tend to prefer the lighter finish I use in the reel.

Last comes an eye cream. The skin around the eyes is thinner and more delicate than the rest of the face, so it benefits from a product formulated specifically for the area. The one I finish with targets the look of dark circles and helps brighten the under-eye. A small amount, patted in gently with the ring finger, is all it takes.

Common questions about layering skincare

Do I really need every one of these steps every night?

No. This is a full template rather than a nightly obligation. Cleansing and hydrating are the constants. Exfoliation is best kept to a couple of times a week for most people, and retinol is built up gradually rather than used from day one. The right combination for you depends on your skin type and how it responds, which is where a personalised plan comes in.

How long before I see a difference?

Hydration and smoothness often improve within days, because you're clearing dull surface cells and sealing in moisture. The deeper benefits of retinol, including refined texture and more even tone, build over weeks to months of consistent use. Skincare rewards patience and regularity far more than intensity.

Can I use retinol if I have dry or sensitive skin?

Usually yes, with the right approach. Starting at a low strength like 0.25%, using it infrequently at first, and applying a hydrator before or after can all make retinol far more comfortable for reactive skin. If you have a chronic condition such as eczema, or you're pregnant or breastfeeding, retinol may not be appropriate, so it's worth checking with a doctor first.

What order do serums and treatments go in generally?

The broad principle is thinnest to thickest, and water-based before oil-based. Cleanse, then any exfoliating or prep steps, then your lightest active serums, then heavier treatments like retinol, and finally your moisturiser and eye cream to seal everything. Sunscreen always sits last in a morning routine.

Why ZO Skin Health specifically?

ZO is a medical-grade range developed to be prescribed and guided by skin professionals, which is why we use it at Wellface. The formulations are potent and the system is designed to work together as a routine, so the steps genuinely complement one another rather than competing. Because the actives are strong, they're best introduced with proper guidance on strength and frequency.

Book a skin consultation with Wellface

A great routine isn't about owning the most products. It's about using the right ones, in the right order, at a pace your skin can handle. My nighttime layering is a brilliant starting framework, but the details, which strength of retinol, how often to exfoliate, whether you need a lightweight or a richer hydrator, are worth tailoring to your own skin.

If you'd like a personalised skincare plan built around ZO Skin Health, I'd be glad to assess your skin and set you up properly.
