Why order matters
Skincare products are formulated to work at a specific skin depth and in a specific pH environment. A thicker product applied before a thinner one creates a physical barrier that prevents the thinner product from penetrating - so your expensive serum sits on top of your moisturiser, doing very little. Applying a high-pH product before a low-pH acid disrupts the acid's ability to exfoliate effectively.
The universal rule is simple: thinnest to thickest, water-based before oil-based. But there are important exceptions worth knowing.
Morning routine order
Step 1: Cleanser
Start with a clean surface. In the morning, a gentle rinse or very mild cleanser is usually enough - your skin doesn't need aggressive cleansing in the morning since it wasn't exposed to sunscreen, makeup, or pollution overnight. Over-cleansing strips barrier lipids that your skin worked all night to produce.
Step 2: Toner (if using)
Apply to slightly damp skin immediately after cleansing. Toners primarily add a first layer of hydration and balance the skin's surface pH after cleansing. Apply by patting gently - not wiping - to avoid irritation. If your toner contains actives (AHAs, BHAs), this is where they go. Allow 30-60 seconds to absorb.
Step 3: Serum
Serums are the most active part of your routine - high concentrations of targeted ingredients in a lightweight base designed for deep penetration. Apply to slightly damp skin for better absorption. Morning serums typically focus on antioxidants: Vitamin C, Niacinamide, or Ferulic Acid protect against UV-induced free radical damage throughout the day.
Step 4: Eye cream (if using)
Apply before moisturiser - the skin around the eye area is thin and needs targeted ingredients to penetrate rather than being sealed under a heavier cream. Use your ring finger to gently tap rather than rub.
Step 5: Moisturiser
Seals in the serum and provides a protective layer. Choose a lighter formulation for morning - gel or lotion for oily and combination skin, cream for normal and dry. Apply while skin is still slightly damp from previous steps for better humectant performance.
Step 6: SPF - always last
Sunscreen must go on last in the morning routine. Chemical filters need to bind to skin proteins to work - applying moisturiser or other products on top disrupts this. Mineral (physical) filters sit on the skin surface and physically reflect UV - they also need to be the outermost layer to do their job. Wait 30-60 seconds after moisturiser before applying SPF.
If you use a moisturiser with SPF built in, you're likely under-applying it. Sunscreen requires a specific amount to achieve its rated SPF - about a quarter teaspoon for the face alone. Most people apply far less when it's combined with a moisturiser.
Evening routine order
Step 1: Oil cleanser or micellar water
If you wore sunscreen or makeup, start here. Oil-based cleansers break down sunscreen (which is specifically designed to resist water) and heavy makeup. This is the first cleanse.
Step 2: Water-based cleanser
The second cleanse removes residue from the oil cleanser, sweat, and environmental debris. If you didn't wear sunscreen or makeup, you can skip to this step.
Step 3: Exfoliant (2-3 times per week)
Acids (AHAs like Glycolic or Lactic, BHAs like Salicylic) go here - after cleansing but before other products. They work at a specific low pH that gets disrupted if applied over other products. Do not use exfoliants on the same nights as retinol until your skin is well acclimatised to both.
Step 4: Treatment serum
Evening serums can be more potent than morning ones - Retinol, Peptides, Niacinamide, or Bakuchiol. Apply to clean, dry skin. For retinol particularly, some people find "buffering" (applying over a thin layer of moisturiser rather than bare skin) reduces irritation without significantly impacting efficacy.
Step 5: Moisturiser
Richer than your morning moisturiser. Ceramide-containing creams are ideal for evening as they replenish the barrier lipids that support overnight repair. Apply while skin is slightly damp.
Step 6: Facial oil or occlusive (optional)
A few drops of a non-comedogenic facial oil (squalane, rosehip) or a pea-sized amount of a heavy occlusive (petroleum jelly, shea butter) applied as the very last step creates a seal that dramatically reduces overnight water loss. This is sometimes called "slugging" at the extreme end, or just routine moisturisation at the mild end.
Products that should never be layered together
- Vitamin C + AHAs - both are low pH and can work together, but for beginners the combination can be irritating. Use vitamin C in the morning and acids at night.
- Retinol + AHAs/BHAs - using both on the same night significantly increases irritation and sensitisation, especially early on. Alternate nights instead.
- Benzoyl Peroxide + Retinol - benzoyl peroxide oxidises and deactivates retinol. Apply at different times of day or on alternate nights.
- Two different oils - using multiple facial oils in the same routine adds little benefit and can feel heavy. Pick one.
Frequently asked questions
How long should I wait between skincare steps?
For most steps, 30-60 seconds is sufficient - enough time for the product to stop feeling tacky. Allow 1-2 minutes after actives like vitamin C or retinol before applying the next product. You don't need to wait 10-20 minutes between every step unless a product specifically instructs it.
Should I apply skincare to a wet or dry face?
Slightly damp skin (not soaking wet) is ideal for most products - humectants like hyaluronic acid perform better with some surface moisture to attract. Retinol is an exception: applying to dry skin reduces irritation, and the instructions often specifically recommend it.
Does niacinamide cancel out vitamin C?
This is a myth based on old chemistry research. At the concentrations used in modern skincare products and in normal use conditions, niacinamide and vitamin C do not interact negatively. They can be layered or used in the same product without issue.
Can I apply SPF before moisturiser?
No - SPF should always be the last step. Applying anything on top of sunscreen disrupts how it sits on the skin and reduces its effectiveness. If you prefer a more streamlined morning routine, look for a moisturiser with SPF already formulated in - but apply it generously.
What if I only use three products?
Cleanser → moisturiser → SPF is a complete and effective morning routine. Cleanser → moisturiser is a complete evening routine. More products don't automatically mean better results. A simple routine applied consistently outperforms a complex one applied irregularly.
