How Much Skincare Product Should You Really Be Using? Let’s Talk Dosage, Timing, and Shelf Life

Recently, a client came in for a non-skincare service, and for the second time in a row, I noticed something: she had buildup on her skin. Naturally, I asked about her routine. She mentioned a particular product she’d been using regularly. It didn’t take long to figure out what was likely happening—she was using too much of it.

Let’s set the record straight: your skin is like a sponge—it can only absorb so much. Once it’s saturated, more product just sits on top, leading to buildup, clogged pores, or wasted product.

So, how much skincare product should you be using? And how long should it last? Let’s break it down—visually, in terms you’ll recognize (like coins and teaspoons), and practically, so you get the best from your routine without overusing or underusing.

Step-by-Step Product Amounts (Think Coins!)

Here’s a quick guideline using US coin-size references or standard kitchen measures:

  • Cleanser: Use a nickel-sized amount. More doesn’t mean a deeper clean.

  • Toner (if liquid): A few drops on a cotton round or palm is plenty.

  • Serum: A dime-sized amount. These are potent; more isn't better.

  • Moisturizer: About a nickel-sized dollop for the face, more if applying to neck.

  • Eye Cream: A grain of rice per eye is enough. Gently pat, don’t rub.

  • Sunscreen: For your face and neck, use about 1/2 teaspoon or a quarter-sized amount. For the body, around 1 oz (a shot glass) is standard.

Timing Matters: Let It Absorb

Give each product about 30–60 seconds to absorb before layering the next. This helps prevent pilling (those annoying flakes of product that roll off your skin) and ensures your skin is absorbing each step fully.

Start With a Clean Face

Before applying any product, always cleanse your skin properly. If yesterday’s products or makeup are still sitting in your pores, today’s serum isn’t going anywhere helpful. Think of it as prepping a canvas—clean and clear skin allows products to penetrate and perform as intended.

Read the Directions (Seriously!)

Each skincare product is unique. While general rules help, always read the instructions. Some serums may suggest nightly use only; some creams are designed for spot treatment. Directions also often recommend how much to use—which helps you avoid overuse and waste.

How Long Should Products Last?

Understanding shelf life helps with budgeting, planning, and ensuring your products stay effective. Here’s a rough idea:

Product Size Typical Usage Frequency Should Last
Cleanser 8 oz 2x daily 3–4 months
Toner 4–8 oz 2x daily 3–5 months
Serum 1 oz 2x daily ~3 months
Moisturizer 1–2 oz 2x daily 2–3 months
Sunscreen 3–4 oz Daily body use ~1 month if used properly
Eye Cream 0.5 oz 2x daily 4–6 months

Product Expiry Guidelines: When to Toss

Yes, the expiration date on the bottle matters—but the countdown really starts once it’s opened. For example, if the expiration date is Jan 2027, but you opened the product in Jan 2025, you need to follow the guidelines listed on the back of your product.  If none are listed on your bottles, you can use the ones below as a general guideline.

Here’s a general guideline:

  • Natural or low-preservative products (like Victoria DeAnn): Use within 3 months, definitely no more than 6 months after opening.

  • Most creams or lotions: Use within 6–12 months after opening.

  • SPF products: Check the printed expiry date, but toss after 12 months from opening, especially if exposed to heat or light.

Tip: Write the opening date on the bottle with a permanent marker—it’s a game-changer for product tracking. Or, you can even set a calendar reminder on your phone.  

 

Using the right amount of skincare product is just as important as choosing the right product. A little goes a long way when applied correctly and consistently. Overusing not only wastes product but can also lead to skin congestion or irritation.

Let your skincare routine be smart, simple, and effective—and if you're ever unsure, don't hesitate to ask your esthetician. We’re here to guide you, one drop at a time.
