How to Layer Serums: The No-Nonsense Guide to Combining Actives
Read ahead to discover exactly how to layer serums for the best results.
When it comes to skincare, serums are the MVPs—targeted, effective, and designed to tackle everything from fine lines to dark spots.
As someone who’s tested more skincare products than I care to admit, figuring out how to layer my active facial serums for maximum efficiency was a process of trial and error (and a few cringe-worthy mishaps).
Between trying to use up all my stash and keeping my skin type happy, I had to get serious about what works together and what doesn’t. The real magic (or disaster) happens when you layer them. Knowing how to combine active ingredients is key to maximizing results while avoiding irritation.
This guide will help you navigate how to layer serums, what works together, what doesn’t, and when to apply them for the best skin possible.
Choosing the Best Serums for Your Skin Type
Finding the right serums starts with understanding your skin type and what it needs to thrive. Here’s a quick breakdown of common skin types, their characteristics, and the serums that work best for each.
Dry Skin
If your skin often feels tight, flaky, or rough, you’re dealing with dryness. This means your skin lacks the moisture it needs to stay supple. Serums with hyaluronic acid or ceramides are a must—they draw water into the skin and help repair its protective barrier, leaving it soft and hydrated.
Oily Skin
Does your face look shiny by midday, and are you prone to clogged pores or blackheads? That’s classic oily skin, caused by overactive sebaceous glands. Lightweight, water-based serums with niacinamide can help balance oil production, while salicylic acid works to deep-clean pores and prevent breakouts.
Sensitive Skin
If your skin is prone to redness, irritation, or stinging when trying new products, you likely have sensitive skin. Gentle, soothing ingredients like centella asiatica, aloe vera, or chamomile are your best bet to calm inflammation. For anti-aging, try bakuchiol as a gentler alternative to retinol.
Combination Skin
Combination skin is, well, a combination. You might have an oily T-zone (forehead, nose, and chin) and drier cheeks. It’s best to address these areas separately. Use hydrating serums with hyaluronic acid on dry areas, and oil-balancing serums like niacinamide on the oilier parts of your face.
Mature or Aging Skin
If fine lines, wrinkles, and a loss of firmness are your main concerns, focus on anti-aging serums. Retinol helps boost cell turnover and reduce wrinkles, peptides support collagen production, and vitamin C brightens skin while protecting against free radicals.
Knowing your skin type and tailoring your serums accordingly is the first step to building a routine that actually works.
Understanding the Different Types of Serums
Serums are your skin’s secret weapon, but with so many options, it can feel overwhelming to choose the right one.
Not all serums are created equal—and actually, that’s a good thing. Each type is designed to address a specific skin concern, such as hydration, anti-aging, and brightening.
Here’s a quick breakdown of the most common types of serums and their key benefits:
| Active Ingredient | Main Purpose | Key Benefits | Best For |
|---|---|---|---|
| Hyaluronic Acid | Deep hydration and moisture retention. | Plumps skin, reduces appearance of fine lines | Dry, dehydrated, or mature skin |
| Vitamin C | Brightens skin tone and reduces dark spots. | Fades hyperpigmentation, boosts collagen | Dull or uneven skin tone |
| Retinol | Anti-aging powerhouse that boosts cell turnover. | Reduces wrinkles, improves firmness | Aging or mature skin |
| Niacinamide | Balances oil production and strengthens the skin barrier. | Minimizes pores, brightens skin | All skin types, especially oily skin |
| Glycolic Acid (AHA) | Exfoliates dead skin cells for a smoother texture. | Refines texture, evens skin tone | Rough texture, dull or acne-prone skin |
| Salicylic Acid (BHA) | Penetrates pores to reduce oil and breakouts. | Unclogs pores, calms inflammation | Oily or acne-prone skin |
| Bakuchiol | Gentle alternative to retinol. | Smooths fine lines, improves tone | Sensitive or aging skin |
| Centella Asiatica | Soothes irritation and reduces redness. | Calms inflammation, promotes healing | Sensitive or irritated skin |
| Ceramides | Restores and protects the skin barrier. | Locks in hydration, repairs damage | Dry, sensitive, or compromised skin |
| Alpha Arbutin | Targets dark spots and discoloration. | Brightens and evens skin tone | Hyperpigmented or uneven skin tone |
| Peptides | Stimulates collagen production. | Firms skin, reduces fine lines | Aging or mature skin |
| Tea Tree Oil | Antimicrobial active to reduce breakouts. | Clears acne, soothes inflammation | Acne-prone skin |
| Resveratrol | Antioxidant that protects against environmental damage. | Neutralizes free radicals, calms skin | All skin types, especially urban environments |
Why Layering Serums Properly Is Crucial
Serums are concentrated formulas meant to address specific skin concerns. But not all active ingredients play well together. Pair the wrong ones, and you could end up with redness, dryness, or skin that’s worse off than when you started. The goal is to build a routine that works in harmony, targeting your needs in the correct order without overwhelming your skin.
Pro Tip: To get the most out of your skincare routine, always layer serums from the thinnest water-based formulas to the thicker or oil-based serums, allowing each product to fully absorb before moving to the next step.
AM vs. PM: When to Use Certain Serums
Your daytime and nighttime routine should complement your skin’s natural rhythm. Using the right products at the right times can maximize their effectiveness.
Before any skincare routine, be sure to start with clean skin!
Morning (AM) Serums
In the morning, your focus should be on protection and hydration.
- Vitamin C: A powerful antioxidant that protects against free radicals and brightens skin.
- Niacinamide: Helps with redness, hydration, and oil regulation.
- Hydrating Serums: Look for hyaluronic acid or peptides to keep your skin plump throughout the day.
Always finish with sunscreen to protect from harmful UV rays—no exceptions.
Evening (PM) Serums
Nighttime is for repair and renewal, so this is when you bring out the heavy hitters.
- Retinol or Retinoids: Gold-standard ingredients for fine lines, wrinkles, and uneven texture.
- AHAs/BHAs (Chemical Exfoliants): Serums with alpha hydroxy acids, like glycolic or lactic acid, are great for giving your skin a gentle exfoliation, smoothing out texture, and leaving you with a brighter glow. These serums are best at night to avoid sun sensitivity.
- Repairing Serums: Look for ceramides, centella asiatica, or anything soothing to calm your skin after active ingredients.

What Works Together—and What Doesn’t
When you know how to layer serums, you can combine products for maximum absorption and visible results. Some key ingredients work beautifully together, enhancing each other’s benefits, while others can cancel each other out or irritate your skin.
Here’s a straightforward guide to combining actives effectively:
Power Combos You Can Use Together
- Vitamin C + SPF: Protects skin from free radicals and reverses UV damage—your first thing in the morning duo.
- Hyaluronic Acid Serum + Any Active: This hydrating powerhouse pairs well with everything, helping to reduce dryness caused by stronger actives.
- Niacinamide + Retinol: Niacinamide soothes and supports the skin barrier, making retinol more tolerable.
Ingredients to Avoid Mixing
- Vitamin C + Retinol: These two have conflicting pH levels, making them less effective and potentially irritating when used together. Use vitamin C serum in the morning and retinol products at night.
- Retinol + AHAs/BHAs: Double exfoliation can overstrip your skin, leading to redness and irritation especially if you have sensitive skin. Alternate nights if you need both.
- Benzoyl Peroxide + Retinol: Both are strong actives that can cancel each other out and leave your skin dry and sensitive.
Serum Routine for Aging Concerns
If fine lines, loss of firmness, and uneven tone are your main concerns, learning how to layer serums can ensure your products work together to give the best results.
Here’s how to structure your anti-aging routine:
Morning Routine
- Vitamin C: Brightens skin, and boosts collagen production.
- Peptides: Supports skin elasticity and firmness.
- Hyaluronic Acid: Hydrates and plumps the skin.
Evening Routine
- Retinol or Bakuchiol: Reduces wrinkles and improves skin texture.
- Or AHAs/BHAs: gently exfoliating the skin’s surface, improving texture, and a brighter complexion. We don’t recommend pairing retinols with acids so alternate days if you use both.
- Niacinamide Serum: Calms and strengthens the skin barrier.
- Ceramides: Repairs and restores overnight.
The Best Products to Try
Now that you know how to layer serums, it’s time to find the best products for you!
However, navigating the sea of serums can feel overwhelming. Here are some tried-and-true favorites to add to your routine:
Vitamin C Serums
- SkinCeuticals C E Ferulic: A cult favorite with a high concentration of active ingredients. It’s pricey so I like to alternate with a more affordable option like the Timeless.
- Timeless 20% Vitamin C + E Ferulic Acid Serum: Affordable and effective for brightening.
Hydrating Serums
- Vichy Minéral 89 Hyaluronic Acid Booster: Lightweight and ultra-hydrating.

Exfoliating Serums
- Sunday Riley Good Genes All-In-One Lactic Acid Treatment: Reduces hyperpigmentation.
- Pixi Overnight Glow Serum: Has added aloe for a gentle exfoliation.
Mistakes to Avoid When Layering Serums
- Using Too Many Actives: More isn’t better. Limit yourself to 2–3 face serums per routine.
- Skipping a Patch Test: Always test new serums on a small area before applying them to your face.
- Ignoring Skin’s Reaction: If your skin feels tight, stings, or peels, dial back your actives and focus on hydration and repair.
Build a Routine That Works for You
Layering serums doesn’t have to be complicated. Focus on your skin concerns, pick compatible actives, and stick to a consistent AM/PM routine. Remember, your skin is unique—what works for someone else might not work for you, so pay attention to how your skin responds.
