Serums can seem complicated, but they don’t have to be. Think of them as concentrated formulas that deliver targeted support where your skin needs it most. In this guide, we’ll walk through when and how to use serums, how to layer them with the rest of your routine, and how to get the best results from your serum.
Serums can do a lot of good for your skin—but only if they’re used at the right time, in the right way, and with the right expectations. At JENCO, we see them not as miracle products, but as purposeful tools that help support skin health. Here’s how to make the most of them.
Start With Clean Skin
Serums should always be applied to freshly cleansed skin. If you use a toner, this is when you'd apply it—right after cleansing, before any heavier steps. Your skin should be slightly damp but not wet; this helps many serums absorb more effectively.
A Few Drops Is Enough
Serums are concentrated by design. You don’t need more than two or three drops, especially if the formula spreads easily. Applying too much can leave skin feeling sticky or overloaded, which defeats the point.
Apply Gently
You can either apply drops of serum directly onto your skin with the dropper or dispense it onto your fingertips and gently rub them together before applying. Use smooth, upward motions or simply press it in. No need to overthink the technique, just be gentle and let the product do the work.
Let It Absorb Before Moving On
Give your serum 30 seconds to a minute to settle in before you apply your next layer. This helps prevent pilling and allows the formula to absorb fully.
Follow With Oils & Moisturizer (and SPF if It’s Morning)
Serums aren’t meant to replace moisturizers; they work with them. After your serum, apply an oil and/or moisturizer to seal everything in and add a protective layer. If it’s daytime, finish with sunscreen.
When to Use Serums
Most serums can be used once or twice a day, depending on the ingredients. Our Hibiscus Hyaluronic Acid Serum is made for daily use and is especially helpful under makeup or before bed, when your skin tends to lose moisture. Typically, a serum can be used twice a day with a few notable exceptions:
- Vitamin C - Use once a day in the morning
- Retinols - Use once at night
Layering More Than One Serum
If you’re using more than one serum, the general rule is to layer from thinnest to thickest. Start with water-based formulas (like hydrating or antioxidant serums), then follow with anything slightly richer or more treatment-focused. Let each layer absorb for a few moments before applying the next. It’s best to keep it to two serums max per routine—more than that can be counterproductive.
What to Avoid
-
Don’t layer too many serums at once, it can dilute their effectiveness or irritate your skin.
-
Be careful when combining actives like vitamin C, AHAs, or retinoids in the same routine unless you’re sure they’re compatible.
-
Don’t expect instant results. Serums work best when used consistently over time.
Tips for Sensitive Skin
If your skin is reactive or easily irritated, keep your serum routine simple. Introduce one new serum at a time and give it at least a week before adding anything else. Look for formulas that focus on hydration, barrier support, or calming ingredients—and avoid layering too many actives at once. Our Hibiscus Hyaluronic Acid Serum was formulated with sensitivity in mind: no fragrance, no harsh additives—just straightforward hydration that plays well with other products.
The Bottom Line
Serums are not about perfection, they’re about support. Use them thoughtfully, pay attention to how your skin responds, and keep your routine simple. If your skin feels nourished, balanced, and comfortable, you’re doing it right.
