The Secret to Glowing Skin? It Might Be Serum

Why Should You Consider a Serum?

Serums often seem like mysterious skincare products, tucked between toners and moisturizers. Many people use them without fully understanding what they actually do for the skin.

If you’ve ever wondered whether serums are just hype or truly powerful skincare essentials, you’re not alone. We’re here to demystify the serum and explain why it deserves a spot in your routine.

Serums are not just a luxury—they can be a game-changer for your skin’s health, texture, and overall glow. So, let’s dive into what makes this small but mighty product so powerful.

What Is a Serum?

Serums are lightweight skincare products packed with high concentrations of active ingredients. They’re designed to target specific skin concerns like aging, dryness, acne, and discoloration.

The consistency of serums can vary, but most are water-based and feel light on the skin. Some serums may also have a gel-like or silky texture, depending on their formulation.

What makes them special is their small molecular structure. This allows serums to absorb deeper into the skin than creams or lotions, reaching the layers where real changes happen.

Unlike moisturizers that mostly work on the skin’s surface, serums deliver ingredients directly into the deeper layers. This is where they do their best work—repairing, restoring, and rejuvenating.

What Are the Benefits of Serums?

Serums are powerful multitaskers in your skincare routine. Their high concentration of active ingredients makes them effective at treating specific concerns with visible results.

Here are some key benefits of using serums:

1. Fight Signs of Aging

Serums with ingredients like peptides, retinol, and vitamin C boost collagen production. This helps reduce the appearance of fine lines and wrinkles over time.

By firming the skin and improving elasticity, serums can make the face look younger and more radiant. They also help prevent new lines from forming.

2. Hydrate and Plump the Skin

Hyaluronic acid is one of the most popular serum ingredients for hydration. It draws water into the skin and locks it in, keeping your face plump, dewy, and soft.

Serums are ideal for those with dry or dehydrated skin. They restore the skin’s moisture balance and prevent dryness without feeling greasy.

3. Brighten Dark Spots and Even Skin Tone

Serums with vitamin C, niacinamide, or licorice root extract help fade dark spots, acne scars, and uneven skin tone. They also prevent future pigmentation caused by UV exposure.

Over time, regular use leads to a more radiant and uniform complexion. Skin looks clearer, brighter, and more refreshed.

4. Protect Against Environmental Damage

Antioxidant-rich serums protect the skin from free radicals, which are unstable molecules caused by pollution, sun exposure, and stress. These radicals can age the skin and cause dullness.

Serums act like a shield, preventing environmental damage before it occurs. This helps preserve your skin’s youthful appearance for longer.

5. Treat and Prevent Acne

Serums with ingredients like salicylic acid, tea tree oil, or niacinamide can help control acne. They reduce inflammation, shrink active blemishes, and prevent future breakouts.

Because of their light texture, serums don’t clog pores. That makes them perfect for oily or blemish-prone skin types.

Serum vs. Moisturizer: Do You Need Both?

You might wonder: if serums hydrate and repair, do I still need a moisturizer? The answer is yes—serums and moisturizers work best together.

While a serum penetrates deeply and treats concerns, a moisturizer seals everything in. It locks in hydration and forms a barrier that protects the skin’s surface.

Using both ensures that your skin gets powerful treatment and long-lasting moisture. Think of serum as the treatment and moisturizer as the shield.

This combination helps skin stay soft, strong, and protected all day and night.

When Should You Start Using a Serum?

The best time to start using a serum? As early as possible. Prevention is always better than correction when it comes to skincare.

Whether you’re in your 20s and want to preserve your glow, or in your 40s looking to treat fine lines, there’s a serum that fits your needs.

The earlier you introduce serums into your routine, the longer your skin will stay healthy, radiant, and youthful-looking.

How to Use a Serum Properly

To get the most out of your serum, it’s important to apply it correctly and at the right time in your skincare routine. Follow these simple steps:

Step 1: Start with a Clean Face

Always begin with clean skin. Use a gentle cleanser to remove makeup, excess oil, and impurities. If needed, use a makeup remover before washing your face.

Cleansed skin ensures that the serum can absorb effectively without any barriers like dirt or leftover makeup.

Step 2: Apply Toner (Optional but Helpful)

Using a toner can help remove residual dead skin cells. This preps the skin and allows the serum to penetrate more deeply and evenly.

Choose a gentle, alcohol-free toner if your skin is sensitive. Hydrating or exfoliating toners both work well depending on your skin type.

Step 3: Apply the Serum

Use 2–4 drops and gently pat it onto your face and neck. Avoid rubbing harshly or applying too much. Focus on areas where you want the most improvement.

Let the serum absorb into the skin for a few minutes before moving on to the next step.

Step 4: Follow with Moisturizer

Apply your favorite moisturizer to lock in the serum and add extra hydration. This helps form a barrier that prevents moisture from escaping.

Moisturizer ensures the active ingredients stay where they’re needed while protecting your skin’s surface.

Step 5: Apply Sunscreen (Morning Routine Only)

If you’re using a serum during the day, always finish with SPF 30 or higher. This protects your skin from UV damage and helps maintain the benefits of your serum.

Sun protection is a must—especially if your serum contains ingredients like vitamin C or retinol that make skin more sensitive to the sun.

When and How Often Should You Use a Serum?

Most serums are safe for daily use. In fact, many are designed for use both morning and night. However, always check the label and instructions for the best results.

Some serums, like those with retinol, are best used at night due to their sensitivity to sunlight. Daytime serums often focus on protection and hydration.

Start by using your serum once a day and build up to twice a day if your skin tolerates it well. You can also alternate serums depending on your skin’s needs.

Are Serums Right for Every Skin Type?

Yes—serums can be used by all skin types. The key is finding the right formula for your individual skin concerns and sensitivities.

Here are tips on choosing the best serum for your skin type:

Oily/Acne-Prone Skin: Look for lightweight, oil-free serums with salicylic acid or niacinamide to reduce breakouts.

Dry Skin: Choose serums rich in hyaluronic acid and ceramides to deeply hydrate and repair the moisture barrier.

Sensitive Skin: Avoid fragrances and harsh actives. Opt for calming ingredients like chamomile, green tea, or aloe vera.

Dull Skin: Try serums with vitamin C or ferulic acid to brighten and even skin tone.

Aging Skin: Use retinol, peptides, or growth factors to firm, plump, and smooth fine lines and wrinkles.

Always do a patch test before using a new serum, especially if you have sensitive or reactive skin. Apply a small amount to your inner arm or jawline and wait 24 hours.

Are Serums Worth the Cost?

Serums can be more expensive than other skincare products, but they’re also more concentrated. A little goes a long way—and the results can be transformative.

Think of a serum as an investment in your skin’s future. With regular use and the right formula, you’ll notice improvements in texture, clarity, and overall health.

High-quality serums are designed to deliver visible results with minimal product. One bottle often lasts several months when used correctly.

In Summary: Why You Should Use a Serum

Serums offer intensive, targeted care for a wide variety of skin issues. Whether you’re trying to hydrate, brighten, calm, or fight signs of aging—there’s a serum for that.

Adding a serum to your routine could be the missing piece your skin needs. It’s a simple step that makes a big difference when used consistently.

You don’t have to change your whole routine. Start with one serum that fits your goals and build from there. Over time, your skin will thank you.

DQH Knowledge drop: In your 20s, your skin cell turnover decreases. (Cell turnover is a key component in keeping your skin youthful.) You know what else slows down? Your collagen production. Starting in your 20s, collagen decreases by about 1 percent per year. Should you want to prevent fine lines and wrinkles, start by eliminating behaviors that contribute to premature aging. “If it’s bad for you, it’s bad for your skin,” says dermatologist Michel Somenek. “Cigarette smoking reduces blood flow to the skin and causes premature wrinkling and a dull skin texture. Making the repeated pursed motion to inhale can also cause smoker’s lines. Alcohol and recreational drugs are toxins for the skin that damage its cellular structure and DNA,” Somenek tells us. “The faster you eliminate vices while you are young, the better chance your skin and body have to recuperate.” Also, adopting an anti-aging routine in your 20s is key. After all, the best offense is a good defense. We spoke to Somenek and experts Joshua Ross and Audrey Kunin to find out more. Keep reading for the best anti-aging products for your 20s, according to skincare professionals. Sunscreen “We all know that the sun is the number one cause of skin aging and starting the prevention in your 20s is very important,” Ross says. “The majority of your sun damage won’t start to appear until you’re in your 30s, so don’t wait until you see it surface or you’ll be behind the curve. Stay ahead of it with a good-quality zinc-based sunscreen worn daily.” Farmacy Green Defense Daily Mineral Sunscreen An invisible sunscreen with SPF 30, plus botanical extracts meant to protect skin with tons of antioxidants. Bonus: It’s clean and fine to use under makeup. Bareminerals Complexion Rescue™ Tinted Moisturizer Broad Spectrum SPF 30 Although we recommend you use your SPF and moisturizer separately, we also understand moments when you don’t have time or energy for that extra step. For those times, this bareMinerals moisturizer is a great thing to have on hand. Vitamin C Serum “A great introduction to anti-aging is to start with a vitamin C serum in your morning skincare routine,” Ross says. “It’s a powerful antioxidant that will neutralize free radicals and brighten the skin.” He adds that it’s a great way to counteract the effects of the sun’s harmful rays, which, as previously mentioned, are among the biggest causes of premature aging. Drunk Elephant C-Firma™ Vitamin C Day Serum The Drunk Elephant C-Firma is a lightweight serum that promises to give skin a glow by combining the brightening powers of vitamin C with ferulic acid, l-ascorbic acid, and vitamin E. The included sodium hyaluronate is meant to replace hydration loss, so you shouldn’t have to deal with any irritation. Sunday Riley C.E.O. Rapid Flash Brightening Serum This potent serum is jam-packed with vitamin C (15 percent, to be exact), which means it’s a potential superstar at both brightening skin and dousing it in antioxidants. Peptides Using peptides on your skin has many benefits, says Somenek. “The skin barrier is what defends the body against pollution, UV rays, bacteria, and toxins. It can be damaged by several everyday factors. Using topical peptides aids in building a stronger barrier,” he says. “Peptides comprise elastic fibers, which are a type of protein. These fibers help to make skin appear taut and firm. Peptides can also help repair damaged skin, relieve inflammation, and even out skin tone. Some peptides can kill acne-causing bacteria that is common in 20-somethings.” Kunin agrees, saying, “Peptides are an excellent entry point for supporting collagen.” She recommends looking for face and eye treatments that contain these collagen-boosting powerhouses. Charlotte Tilbury Magic Eye Rescue Cream This Charlotte Tilbury super-emollient eye cream has a base of coconut oil and shea butter (read: it’s incredibly hydrating). Botanicals plus peptides are meant to help reduce dark circles and boost collagen, respectively. This creamy moisturizer serves up potent collagen-boosting peptides and pycnogenol, and antioxidant-rich vitamin C. “Instead of sitting on top of the skin, peptides penetrate the outer layer so they go deep. The ‘signals’ they send tell the cells to produce elastin and collagen, which are needed for youthful-looking skin,” explains Somenek. At-Home Peel Pads Remember that skin cell turnover fiasco we talked about earlier? One way to help support it is by exfoliating. “Exfoliation is important to help keep skin fresh and luminous,” Kunin says. She recommends using at-home peel pads as an easy and effective way to exfoliate. “The goal in your 20s is to fight the slowing pace of cell turnover. It is wise to use products that gently exfoliate, yet still remove oil and other impurities. Products that have Alpha Hydroxy Acids (AHA) or Beta Hydroxy Acids (BHA) are a good choice.” According to Somenek, you should only exfoliate two to three times a week. “People of all ages are guilty of over-exfoliating and that can be too much of a good thing,” he says. Dermadoctor Kakadu C Intensive Vitamin C Peel Pad A few swipes of this Derma Doctor powerful peel pad promise to leave your skin glowing and smooth, thanks to the seven (yes, seven) types of chemical exfoliants, including AHA and BHA. It also contains vitamin C via Kakadu plum extract for added brightening and antioxidant protection. KEY INGREDIENTS Kakadu plum extract is sourced from the Kakadu plum, a fruit grown in northern Australia. It contains vitamin C, which restores the skin’s natural barrier, increases collagen production, and soothes irritation. Dr. Dennis Gross Skincare Alpha Beta® Universal Daily Peel Pads These are the gold standard of peel pads, with a cult following and over 900 five-star reviews on Sephora. They’re easy to use and contain a blend of anti-aging exfoliating acids. Emollient Night Cream “In your 20s, you need to start upping the hydration in your skincare routine. You may have been cautious of over-moisturizing because of acne in your teens, but as you enter your 20s, your skin transitions and becomes drier,” Ross says. “I recommend an emollient night cream added into your evening skincare regimen.” “Twenty-somethings need to make sure that they are not using creams that will clog their pores and cause excess oil production,” says Somenek. Opt for non-comedogenic products. Cerave Skin Renewing Night Cream One great choice is the CeraVe Skin Renewing Night Cream, which is a non-comedogenic night cream that leaves skin soft and glowy. It combines the moisturizing powers of ceramides and hyaluronic acid. RoC Retinol Correxion Max Hydration Creme “The best night cream ingredients contain retinol, benzoyl peroxide, and/or salicylic acid or hyaluronic acid. The goal is to moisturize, yet remove excess oil,” says Somenek. This Roc Retinol Correxion cream fits the bill as it contains both hyaluronic acid and retinol so it promises to moisturize while also being non-comedogenic.
