Let's face it: Most of us struggle with more than one skin issue from time to time—whether acne, hyperpigmentation, rosacea, uneven tone, or sun damage. The good news? Most of the active ingredients used to treat your common skin concerns work well together. In fact, many of them often help each other work even better.
The key is to pinpoint your main skin conditions, decipher which active ingredients you need, then figure out how to combine them in a manageable way to get results. Struggling with more than one skin issue doesn’t mean you need to overload on products and ingredients. “Less, but better” is always the best approach to skincare, and we’ll show you how...
Step 1: Identify all of your skin issues.
Start by writing down your skin issues from most concerning to least concerning. Get specific. Are you dealing with dehydration or dullness? Hyperpigmentation or sun damage? Acne and breakouts? If you feel that a couple are tied on your list, don’t worry about that for now. Just do your best.
Step 2: Make a list of active ingredients.
Next, identify all of the active ingredients you should be incorporating into your skincare routine. This will help you shop for the right products. Hopefully, there will be some overlapping. For example, if you suffer from hyperpigmentation and an aging complexion, Vitamin C helps to brighten and even the skin tone, while also stimulating collagen production.
Need some help? Below is a quick cheat sheet to help you figure out which ingredients help to improve certain skin issues:
- Dehydration/Dullness: Hyaluronic Acid, Ceramides
- Hyperpigmentation/Uneven Tone/Sun Damage: AHAs, Vitamin C, Niacinamide
- Breakouts: BHAs/AHAs, Niacinamide
- Redness/Sensitized: Niacinamide, Ceramides
- Aged: Retinol, Vitamin C, AHAs
Step 3: Figure out your daily + nightly routine.
The key to creating a simple routine is knowing which time of day you should be using these active ingredients. Generally speaking, active ingredients can be categorized into morning usage and nightly usage:
- Morning: Ceramides, Hyaluronic Acid, Vitamin C
- Night: Niacinamide, AHAs, BHAs, Retinol
Quick Tip: Niacinamide and Vitamin C can be used morning and night, if needed. If you struggle with pigmentation, redness, and occasional breakouts, you may want to incorporate these two ingredients twice per day. However, we strongly advise starting off with these ingredients once a day, then increase later, if necessary.
Step 4: Find the right products.
The next step is finding the right products that incorporate your active ingredients in a seamless fashion. We love serums because they’re lightweight, but usually contain higher amounts of powerful active ingredients. Here at Otto, our Go-Getter and Multitasker serums combine the right active ingredients for the right time of day and are boosted with gentle, effective plant-based extracts.
The Go-Getter Day Serum: Targets Dehydration + Fine Lines & Wrinkles + UV and Environmental Damage
A Hyaluronic Acid serum that boosts collagen and elastin for a firmer, smoother texture. It strengthens your skin barrier against moisture loss and environmental damage—all while fortifying your complexion with enhanced hydration.
Add a cleanser that contains Ceramides, and it’s the perfect routine for the skin issues above. You can also add The Fresh Start Face Oil with 20% Vitamin C at night to achieve even better results (we’ll get to that later).
The Multitasker Night Serum: Targets Breakouts + Dark Spots + Dullness
A Niacinamide serum that gently exfoliates to smooth texture, brighten skin, reduce inflammation and minimize breakouts—all while hydrating with antioxidant support.
If you struggle with breakouts, be sure to consider adding a cleanser with BHAs (salicylic acid) once daily. If your skin is oily or acne prone, adding a retinol product after The Multitasker is also beneficial. Retinol combined with AHAs can increase irritation, so start with retinol after using an AHA serum 2-3 times a week, then increase to nightly as tolerated. You may also want to alternate a retinol product with a Vitamin C oil (like The Fresh Start) every other night to reduce the risk of irritation. Using AHAs before Vitamin C has shown to help it work even better.
The Fresh Start Face Oil: Targets Redness + Premature Aging + Dehydration
A Vitamin C oil blended with antioxidants, fatty acids and nourishing oils to help brighten dark spots, boost collagen, and protect against free radical damage.
Quick Tips: The main thing to consider when combining active ingredients is irritation. Combining exfoliating acids like BAHs/AHAs with retinol or Vitamin C can be irritating and increase sensitivity, so be cautious and go slow. Vitamin C is less irritating than retinol, so you may want to alternate them after using an AHA serum nightly. It’s also extremely important to use AHAs and retinol at night and use sunscreen daily. Adding a daily moisturizer with ceramides can also help reduce irritation and maintain your skin barrier.
Frequently Asked Questions
I have more than one skin concern. Do I need a totally different product for each one?
Not necessarily. Many active ingredients address multiple issues at once, and some pair well together, so the goal is to find the fewest products that cover the most ground rather than layering on separate items for every concern.
How do I figure out which ingredients I actually need?
Start by ranking your skin concerns from most to least bothersome, then match them to ingredients known to help. As a general guide: hyaluronic acid and ceramides for dehydration/dullness; AHAs, vitamin C, and niacinamide for hyperpigmentation or sun damage; BHAs/AHAs and niacinamide for breakouts; niacinamide and ceramides for redness or sensitivity; and retinol, vitamin C, and AHAs for signs of aging.
When should I use these ingredients: morning or night?
As a rough rule, hydrating and protective ingredients (ceramides, hyaluronic acid, vitamin C) work well in the morning, while treatment ingredients (niacinamide, AHAs, BHAs, retinol) are better saved for nighttime. Niacinamide and vitamin C are flexible enough to use both morning and night if needed, though it's best to start with once-daily use before adding a second application.
Can I use retinol and AHAs together?
You can, but combining them raises the risk of irritation. A gentler approach is to introduce retinol on nights after using an AHA serum, starting at just 2–3 times a week and building up to nightly as your skin adjusts.
What about combining retinol and vitamin C?
Vitamin C is gentler than retinol, so alternating them on different nights (rather than layering both) can help minimize irritation while still getting the benefits of each.
Does the order I apply ingredients matter?
Yes, applying an AHA before vitamin C is said to help the vitamin C work more effectively.
What's the biggest risk when combining active ingredients?
Irritation, especially when mixing exfoliating acids (AHAs/BHAs) with retinol or vitamin C. Go slowly, introduce one new ingredient at a time, and pay attention to how your skin responds.
Are there other ways to reduce irritation from these actives?
Using a moisturizer with ceramides can help support your skin barrier. It's also recommended to use AHAs and retinol only at night, and to wear sunscreen daily since these ingredients can increase sun sensitivity.
What's an example of a simple routine using these principles?
A hydrating, barrier-supporting product in the morning (with hyaluronic acid and/or ceramides) paired with a treatment-focused product at night (like one with niacinamide, plus a BHA cleanser for breakouts or retinol for oily/acne-prone skin) is one way to cover multiple concerns without overcomplicating your routine.
