Quick Answer
Which skincare ingredients should be in your routine?
Most routines benefit from three basics: a gentle cleanser, a moisturizer with ingredients such as hyaluronic acid or ceramides, and a broad-spectrum sunscreen of SPF 30 or higher. Targeted ingredients like vitamin C, niacinamide, retinoids, peptides, and exfoliating acids can address specific concerns, but they should be introduced gradually and matched to your skin type.
A shelf full of serums can make skincare feel like chemistry homework. The truth is that a good routine rarely needs more than a few well-chosen ingredients, used consistently and introduced at a pace your skin can handle.
This guide covers the ingredients dermatologists and aestheticians talk about most, what each one generally does, who may want it, and what to watch for. It is educational, not personalized medical advice, because your skin type, history, and any skin conditions affect what is right for you.
The Foundation: Hydrate, Protect, Repeat
Hyaluronic acid and ceramides
Hyaluronic acid attracts water to the skin’s surface, while ceramides are lipids that help support the skin barrier. Both show up often in moisturizers designed for dry skin. Fragrance-free formulas are a good default if your skin is easily irritated.
Sunscreen
Daily sunscreen is one of the most effective things you can do for your skin, and Arizona’s strong sun makes it a year-round habit. The American Academy of Dermatology recommends choosing a broad-spectrum, SPF 30 or higher, water-resistant product, and its guidance on selecting sunscreen also covers options for acne-prone, sensitive, and dry skin. Reapply as directed on the label, and after swimming or sweating.
Targeted Ingredients for Specific Goals
Vitamin C
Vitamin C is an antioxidant that may help brighten the skin and protect it from environmental stress. Use it in the morning, under sunscreen. Some formulas can sting on sensitive skin, so start with a gentle concentration.
Niacinamide
Niacinamide, a form of vitamin B3, may help support the skin barrier, calm the look of redness, refine the appearance of pores and balance oil. It is generally well tolerated, which makes it a popular first active.
Retinoids
Retinoids, which are forms of vitamin A, are among the most studied ingredients for fine lines, uneven tone, texture and acne. The AAD’s explanation of retinoids and retinol recommends starting with the least intense formula, using it every other night at first, applying it at night and wearing sun protection during the day. If you are pregnant or planning to be, check with your doctor before using a retinoid.
Peptides
Peptides are short chains of amino acids that signal the skin. In creams and serums, they are generally gentle and help support firmness and smoothness over time.
AHAs and BHAs
Alpha hydroxy acids, such as glycolic and lactic acid, loosen dead surface cells for smoother, brighter-looking skin. Beta hydroxy acids, such as salicylic acid, are oil-soluble and work inside pores, which is why they are common in breakout products. The AAD lists these acids and retinoids among the common active ingredients in anti-aging products in its guide to selecting anti-aging skin care products. Both can cause dryness, irritation, and sun sensitivity.
Ingredients at a Glance
| Ingredient | What it generally does | May suit | Watch for |
| Hyaluronic acid | Draws water to the skin | Dry or dehydrated skin | Usually well tolerated |
| Ceramides | Support the skin barrier | Dry, sensitive or compromised skin | Heavy textures for very oily skin |
| Vitamin C | Antioxidant, brightening | Dullness, uneven tone | Stinging on sensitive skin |
| Niacinamide | Supports barrier, refines the look of pores | Oily, blemish-prone or uneven skin | Rare flushing or irritation |
| Retinoids | Encourage cell turnover, smooth texture | Fine lines, texture, acne | Dryness, peeling, sun sensitivity |
| Peptides | Support the look of firmness | Mature or dull skin | Usually gentle |
| AHAs | Exfoliate the surface | Dullness, rough texture | Irritation, sun sensitivity |
| BHAs | Clear oil from pores | Oily or acne-prone skin | Dryness, irritation |
| Sunscreen | Protects against UVA and UVB | Everyone | Needs daily, repeated use |
How to Introduce New Ingredients Without Irritation
- Add one new product at a time and give your skin a couple of weeks before adding another.
- Patch test on a small area first, especially with acids and retinoids.
- Start low and slow, using actives a couple of nights a week before building up.
- Avoid stacking several strong exfoliants, such as a retinoid, an AHA and a scrub, in the same routine unless a provider guides you.
- Moisturize and wear sunscreen daily to support your skin while it adjusts.
- Stop and ask for guidance if you have persistent burning, swelling or a rash.
Be patient, too. Hydrating products can improve skin within days, but most active ingredients take at least six weeks to show results, and some take up to three months.
Matching Ingredients to Your Skin Type
Understanding your unique skin profile is the foundation of any effective skincare regimen. When you tailor your daily products to your specific needs—whether that is locking in moisture, controlling excess sebum, or soothing inflammation—you maximize the benefits of active ingredients while minimizing irritation. A personalized approach ensures that every drop of serum or moisturizer works harmoniously with your skin’s natural barrier to deliver healthy, glowing results.
- Dry skin: hyaluronic acid, ceramides, and a gentle cleanser.
- Oily or acne-prone skin: a BHA, niacinamide, and non-comedogenic moisturizers and sunscreens.
- Sensitive skin: fragrance-free products, fewer actives, and a slow introduction.
- Mature skin: retinoids, peptides, and vitamin C, with daily sunscreen.
- Dark spots or uneven tone: vitamin C, niacinamide, a retinoid, and daily SPF, with professional guidance for stubborn pigment.
Where Professional Treatments Fit
Home ingredients and in-clinic treatments do different jobs. Facials and peels can refine texture and tone in ways products alone cannot, and they come with their own instructions. For example, our pre-treatment guidance asks you to pause retinol, vitamin C, and exfoliating acids for about three to five days before microneedling RF and five to seven days before a chemical peel, so tell your provider everything in your routine.
If you would like a plan built around your skin, our custom Signature Facial begins with a skin assessment and is tailored to your concerns, and our Skin Treatments menu shows other ways to support what you do at home.

Skincare Ingredient Questions, Answered
Do I need every ingredient on this list?
No. Start with a cleanser, moisturizer and sunscreen, then add one or two targeted ingredients that match your main concern.
Can I use vitamin C and a retinoid together?
Many routines keep them apart, with vitamin C in the morning and a retinoid at night. Tolerance varies, so ask your provider if your skin is sensitive.
In what order should I apply products?
A common approach is to go from the thinnest to the thickest texture and finish with sunscreen in the morning. Follow the directions on each product.
How long until I see results?
Hydration can show up in days. Most active ingredients take at least six weeks, and some take up to three months.
Should I stop active ingredients before a facial or peel?
Often, yes, for a few days. Your provider will give treatment-specific instructions, so follow those rather than a general rule.
