How to Layer The Ordinary Products: Complete Routine Guide

The Ordinary makes effective skincare affordable. The tradeoff is that their single-ingredient approach means you are the formulator. You choose what to combine, in what order, and with what timing. Get it right and you have a clinical-grade routine for under $50. Get it wrong and you have irritation, pilling, and wasted product.

This guide walks through how to layer the most popular The Ordinary products for both morning and evening routines, including which products conflict and the wait times between each step.

The Core Principle: Water, Oil, Suspension

The Ordinary categorizes their products by formulation type. This matters because formulation determines layering order more than ingredient type does.

Layer in this order:

1. Water-based solutions (clear, watery liquids): These go first because they are the thinnest and absorb fastest.
2. Anhydrous (oil-based) solutions: Oils and oil-based serums go after water-based products.
3. Suspensions and creams: Thicker formulations that sit on the skin go last, before moisturizer.

This is the same thin-to-thick principle that applies to all skincare layering, but it is especially important with The Ordinary because their formulations vary widely in texture.

Morning Routine: Product by Product

Here is a morning routine using popular The Ordinary products, with the correct order and timing.

Step 1: Cleanser

Squalane Cleanser (for dry/normal skin) or Glucoside Foaming Cleanser (for oily skin)

Wash, rinse, and pat dry. Do not rub.

Step 2: Hyaluronic Acid 2% + B5

Apply 2-3 drops to slightly damp skin. This is a water-based solution, so it goes on first after cleansing. Pat it in gently.

Wait: 60 seconds

Step 3: Niacinamide 10% + Zinc 1%

Apply 2-3 drops over the HA. Niacinamide is water-based and layers smoothly over hyaluronic acid. The zinc helps with oil control throughout the day.

Wait: 60 seconds

Step 4: Natural Moisturizing Factors + HA

This is your moisturizer. Apply a thin layer.

Wait: 60 seconds

Step 5: Sunscreen

The Ordinary does not make sunscreen (as of this writing). Use a separate SPF 30+ sunscreen as your final step. Wait 2 minutes before applying makeup.

Total morning routine time: approximately 5 minutes

Morning alternatives

• Swap Niacinamide for Vitamin C Suspension 23% + HA Spheres 2%: If brightening is your priority. Apply the vitamin C after HA, wait 1-2 minutes. Note: this suspension is thick and gritty. It may pill under some sunscreens. If pilling is a problem, try Ascorbyl Glucoside Solution 12% instead (water-based, layers better). See the vitamin C wait time guide for absorption details.
• Add Alpha Arbutin 2% + HA: For hyperpigmentation. Apply after HA, before niacinamide. It is water-based and layers well. Wait 60 seconds.

Evening Routine: Product by Product

Evenings are where the active ingredients do their heavy lifting.

Step 1: Cleanser

Double cleanse if you wore sunscreen or makeup. Oil-based cleanser first (Squalane Cleanser), then a water-based cleanser.

Step 2: Hyaluronic Acid 2% + B5

Same as morning. Apply to damp skin.

Wait: 60 seconds

Step 3: Active treatment (choose ONE per night)

This is where most layering mistakes happen. Do not stack multiple strong actives. Pick one per evening.

Option A: Retinol 0.5% in Squalane (cell turnover, anti-aging)

• Apply 2-3 drops after HA
• Wait 15-20 minutes
• Suitable for adapted skin; start with Retinol 0.2% if you are new

Option B: AHA 30% + BHA 2% Peeling Solution (deep exfoliation)

• Apply a thin layer to dry skin (skip the HA on this step; apply directly after cleansing)
• Leave on for no more than 10 minutes
• Rinse off thoroughly
• Then apply HA to damp skin and continue with moisturizer
• Use once per week maximum

Option C: Azelaic Acid Suspension 10% (acne, rosacea, pigmentation)

• Apply after HA
• Wait 1-2 minutes
• Can be used nightly

Option D: Lactic Acid 10% + HA (gentle exfoliation, hydration)

• Apply after HA
• Wait 15-20 minutes
• Use 2-3 nights per week; do not combine with retinol on the same night

Step 4: Natural Moisturizing Factors + HA

Apply after your active treatment has absorbed.

Total evening routine time: 5-25 minutes depending on the active

Weekly Schedule With The Ordinary

Here is a balanced weekly rotation that avoids conflicts and gives your skin rest days.

This gives you three retinol nights, one AHA/BHA night, one lactic acid night, one azelaic acid night, and one rest night. Your skin gets consistent treatment without being overwhelmed.

Product Conflicts to Avoid

The Ordinary's product page has a built-in conflict checker, but here is a practical summary of the most common mistakes.

Never use together (same routine)

• Vitamin C + Retinol: pH conflict. Use vitamin C in the morning, retinol at night.
• AHA/BHA Peeling Solution + Any other active: This peel is strong enough on its own. Do not layer anything else active on the same night.
• Retinol + Direct acids (AHA, BHA): Over-exfoliation risk. Alternate nights.
• Vitamin C (L-ascorbic acid) + Niacinamide at high concentrations: While modern research shows they are compatible, The Ordinary specifically recommends against layering their Vitamin C Suspension 23% with Niacinamide 10%. This is likely a formulation-specific concern (the suspension's thick texture does not layer well over water-based niacinamide).
• Peptide products + Direct acids: Acids can break down peptide bonds, rendering the peptides inactive.

Use with caution

• Multiple water-based serums: You can layer 2-3 water-based The Ordinary products, but too many can cause pilling. Three is usually the practical limit.
• Squalane-based products stacked: Retinol 0.5% in Squalane + 100% Plant-Derived Squalane = a lot of oil. If you are oily-skinned, pick one.
• Buffet + Copper Peptides: The Ordinary says these conflict. Use Buffet and "Buffet" + Copper Peptides 1% on alternating nights, not together.

Wait Times for Popular The Ordinary Products

Dealing With Pilling

Pilling is the most common complaint when layering The Ordinary products. To minimize it: press products into skin rather than rubbing, use only 2-3 drops per serum, wait the full recommended time between layers, and avoid layering silicone-based products (Azelaic Acid Suspension) directly under water-based ones. If three serums pill, drop back to two.

Timing Multiple Wait Periods

A typical The Ordinary evening routine with retinol has at least three wait periods. Tracking how long to wait between skincare steps manually every night gets tedious. Layered lets you set up your full routine with custom wait times per step and walks you through it with haptic taps on your Apple Watch.

Beginner The Ordinary Starter Routine

If you are new to The Ordinary and feeling overwhelmed by the product range, start here. This uses just four products.

Morning:

1. Squalane Cleanser
2. Natural Moisturizing Factors + HA
3. Sunscreen (not The Ordinary)

Evening:

1. Squalane Cleanser
2. Hyaluronic Acid 2% + B5 (on damp skin, wait 60 seconds)
3. Natural Moisturizing Factors + HA

Use this for 2 weeks. Then add Niacinamide 10% + Zinc 1% to your morning routine. After another 2 weeks, introduce one active to your evenings (retinol or lactic acid, not both). Build up gradually. Your skin will thank you.

Quick Takeaway

Layer The Ordinary products thin to thick: water-based solutions first, then oil-based, then suspensions and creams. Use one active per evening. Avoid combining retinol with direct acids, vitamin C with retinol, or peptides with acids in the same routine. Wait the recommended time between each step for best absorption. Start with a minimal routine and add products one at a time. The skincare layering guide covers general layering principles if you want the broader context beyond The Ordinary.
