What a Face Serum Does
A face serum is a concentrated treatment. Compared with a moisturizer, it has a thinner, often watery texture and a higher concentration of active ingredients, so it can deliver more of what your skin needs in a few drops. Moisturizers mostly protect and seal in hydration. Facial serums are where you target specific skin concerns like dullness, fine lines, dark spots or congestion.
Serums go on after cleansing and toning and before moisturizer. Because the texture is light, they fully absorb in a minute or two, so they layer well under creams and sunscreen and won't pill under makeup.
Sonya Dakar has spent more than four decades formulating with botanical extracts and nourishing oils, and her serums follow the same idea: concentrated ingredients, gentle enough to use every day. Each one is built around a clear purpose, so it's easy to choose the right face serum for your skin.
Hyaluronic Acid Serum for Hydration
Hyaluronic acid is a humectant that can hold many times its weight in water. A hyaluronic acid serum draws moisture into the skin so it looks plumper and smoother, and fine lines caused by dehydration soften almost right away.
Barrier Bliss is our hydrating serum. It's a water-based, lightweight texture made with sodium hyaluronate, glycerin, panthenol and allantoin, plus antioxidant plant extracts. It's free of fragrance and essential oils, which makes it a safe choice for sensitive skin, and it works for every skin type.
Hyaluronic acid works best on damp skin. Apply it right after cleansing, then follow with moisturizer to lock in the water it pulls in. Ultima C Serum and Stem Cell Transformer also contain hyaluronic acid, so you get hydration with every serum in this collection.
Hydrating Serum for Dry Skin
Dry skin needs more than a single layer of moisture. Apply a hydrating serum to damp skin, follow with a rich moisturizer, then seal with a face oil or balm on very dry nights. If your skin feels tight within an hour of moisturizing, add a second thin layer of serum before your cream. Our hydrating moisturizers pair well with Barrier Bliss.
Vitamin C Serum for Brightness
A vitamin C serum is one of the most useful additions to a morning routine. Vitamin C is an antioxidant that helps protect skin from free radicals caused by sun exposure and pollution, and it helps even out skin tone and fade dark spots over time.
Ultima C Serum delivers 15% vitamin C from two stable forms, magnesium ascorbyl phosphate and 3-glyceryl ascorbate, along with hyaluronic acid and antioxidant extracts from Kakadu plum, goji, hibiscus and green tea. It's formulated for every skin type, including oily, combination and sensitive skin.
Many vitamin C products use L-ascorbic acid, the pure form. It's effective, but it breaks down quickly when exposed to air and light, and higher concentrations can sting. Stable forms like the ones in Ultima C hold up better, which matters for a product you'll use every morning. Store any c serum in a cool, dark place and close the cap tightly.
Brightening Serum for Dark Spots and Uneven Tone
A brightening serum helps fade dark spots, post-breakout marks and uneven tone. Vitamin C is the most common brightening ingredient, and gentle exfoliation helps by clearing away the dull surface cells that hold pigment.
For targeted dark spots, add Fade Away after your serum. It combines a vitamin C derivative with daisy flower extract and brightening peptides, and it's free of hydroquinone and tretinoin. Wear sunscreen every morning, since sun exposure darkens existing spots and causes new ones. For more options, browse our dark spot correctors.
Anti Aging Serum for Fine Lines and Firmness
An anti aging serum focuses on the visible signs of aging skin: fine lines, wrinkles, loss of firmness and rough texture. The most useful active ingredients for this are retinoids, peptides and antioxidants.
Retinu is our retinoid serum. It uses hydroxypinacolone retinoate (HPR), a gentle retinoid that doesn't need the same conversion steps as retinol, paired with ceramides, squalane, resveratrol and a stable form of vitamin C. That makes it a good fit for people who've found retinol too irritating. Start two or three nights a week and increase as your skin adjusts.
Stem Cell Transformer is a concentrated serum with green apple stem cells, a peptide, sodium hyaluronate, vitamin C and antioxidant oils. It works as a peptide serum for skin that's losing firmness and needs hydration at the same time.
Research links retinoids and vitamin C to increased collagen production over time, which is why they're the backbone of most anti-aging routines. Stubborn wrinkles take time, so plan on 8 to 12 weeks of consistent use before judging results. For more targeted picks, see our anti-aging serum for wrinkles and serums for aging skin collections.
Serums for Oily Skin and Breakouts
Oily skin still benefits from a serum, as long as the formula is lightweight. Super Clear is a salicylic acid serum with niacinamide that helps with oil control, clears clogged pores and calms the look of redness. Botanicals like centella asiatica and calendula keep it gentle, and it's alcohol free.
If you have combination skin, apply Super Clear to your T-zone and use a hydrating serum on drier areas. Super Clear and Ultima C can be used in the same routine: vitamin C in the morning, salicylic acid at night.
Key Ingredients in Our Facial Serums
Facial serums work because they deliver concentrated ingredients in a texture built for fast absorption. Here's what each of ours brings to your specific skin needs:
-
Vitamin C in Ultima C Serum brightens dullness, evens skin tone and adds radiance.
-
HPR retinoid in Retinu speeds up cell renewal to refine skin texture and reduce fine lines.
-
Peptides and green apple stem cells in Stem Cell Transformer help skin look firmer and smoother.
-
Hyaluronic acid in Barrier Bliss, Ultima C and Stem Cell Transformer draws in water for instant hydration.
-
Salicylic acid and niacinamide in Super Clear clear pores and help balance oil.
Barrier Bliss is fragrance free, which makes it the go to solution for reactive skin. Our other serums include botanical extracts, so check each ingredient list if you're sensitive to plant oils or essential oils.
Serums for All Skin Types
Each serum here is formulated for several skin types, so you don't need a different product for every season. If you already use other serums or beauty products with strong actives, such as alpha hydroxy acids or prescription retinoids, introduce ours one at a time so your skin isn't overloaded. For targeted results, give each serum six to eight weeks of consistent use. Retinoids and peptides combat signs of aging gradually, and wrinkle reduction builds over months, not days.
How to Choose the Best Serum for Your Skin
The best serum is the one that matches your main concern. Start there:
-
Dehydrated or dry skin: Barrier Bliss
-
Dullness, uneven tone or dark spots: Ultima C Serum, with Fade Away on spots
-
Fine lines and texture: Retinu
-
Loss of firmness: Stem Cell Transformer
-
Oily or acne prone skin: Super Clear
Most people do well with two serums: vitamin C in the morning and a treatment serum at night. Using more than two serums at once rarely helps and makes it harder to tell what's working. If you want more help narrowing it down, see our picks for the best serums for face.
How to Add a Face Serum to Your Skincare Routine
Morning routine: Cleanse, tone, then apply 3 to 4 drops of Ultima C Serum or Barrier Bliss to your face and neck. Let it absorb, then apply moisturizer and sunscreen. If you wore makeup the night before, make sure your cleanser removed all of it first, so the serum reaches clean skin.
Evening routine: Cleanse, then apply your treatment serum: Retinu, Stem Cell Transformer or Super Clear. Follow with moisturizer.
A few tips help any skincare regimen:
-
Patch test new serums on your jawline for a few days before using them on your whole face.
-
Apply serums from thinnest to thickest, and let each one absorb before the next.
-
Follow each product's directions for how often to use it, especially retinoids and acids.
-
Wear sunscreen daily when you use vitamin C, retinoids or exfoliating acids such as alpha hydroxy acids.
If you have persistent skin concerns or a skin condition, a board certified dermatologist can help you build a plan around these products.
FAQ
What does a face serum do?
A face serum delivers a high concentration of active ingredients in a lightweight texture that absorbs quickly. It targets specific concerns, such as dryness, dark spots, fine lines or breakouts, more directly than a moisturizer can.
Should I use a serum before or after moisturizer?
Before. Apply serum to clean skin after cleansing and toning, let it absorb, then follow with moisturizer. Thinner products go on first so they can reach the skin, and moisturizer seals them in.
Can I use vitamin C and retinol serums together?
Yes, but use them at different times of day. Apply a vitamin C serum like Ultima C in the morning for antioxidant protection, and use a retinoid like Retinu at night. That split lowers the chance of irritation.
Which serum is best for sensitive skin?
Barrier Bliss is free of fragrance and essential oils and focuses on hydration, so it's the gentlest place to start. Retinu uses a gentle retinoid that's easier for sensitive skin to tolerate than standard retinol. Patch test any new serum first.
