In this review, we’ll break down what makes this serum unique—from its fermented ginseng extract to its lightweight, silky texture. We’ll explore what real customers report experiencing, who this product works best for, and whether it’s worth the luxury price tag. Our goal? To help you decide if this activating serum deserves a spot in your skincare routine, without the hype or unrealistic expectations.
Product Overview and Key Ingredients

We’ve been exploring the Sulwhasoo First care Activating Serum, and we need to start by explaining what makes this product unique in the skincare world. According to the manufacturer, this is designed as a first-step activating serum—meaning you apply it right after cleansing, before your other serums and treatments. The brand positions it as a preparatory step that helps your skin better absorb everything you layer on top. The star ingredient here is 500-hour aged fermented ginseng extract, which Sulwhasoo highlights as their signature Korean herbal ingredient. The formula also includes Korean herb extracts and vitamin C, targeting visible fine lines, dryness, and dullness. The texture is described as lightweight and silky, which customers consistently confirm in their reviews. We appreciate that this comes in both full-size and mini travel versions, with the standard bottle containing 60ml of product (note: some listings mistakenly reference 90ml, but verified purchases confirm the actual size is 60ml).
Looking at what’s actually in this serum and what it does for your skin, we found that customers notably mention the immediate hydration and plumping effect they experience. The fermented ginseng extract is the formulation’s hero—fermentation is a traditional Korean skincare process that breaks down ingredients into smaller molecules that can penetrate skin more effectively. While the brand mentions vitamin C in the product name, it’s worth noting that this appears to work more as a supporting ingredient rather than a primary active in the traditional vitamin C serum sense.What really stands out in reviews is how this product functions: many users describe it as creating a “hydrated base” that makes their subsequent skincare products absorb and perform better. one reviewer with mature, post-menopausal skin specifically mentioned it “helps support the skin barrier,” which is particularly important if you’re using stronger actives like retinoids or exfoliating acids.The lightweight, instantly-absorbing texture means there’s no stickiness or heaviness, making it genuinely easy to layer under other products without pilling or interfering with makeup application.

Texture, Absorption and Application Experience

We were immediately impressed by the lightweight, silky texture that Sulwhasoo describes as their signature formula. According to customer reviews, this serum has what many describe as a unique liquid-oil hybrid consistency—it’s not quite as watery as a typical essence, but it’s definitely not heavy or oily either. One reviewer with mature, post-menopausal skin noted that it “absorbs instantly with no stickiness,” which we found to be a consistent theme across hundreds of reviews. When we applied it to the back of our hand for testing,we could see how it spreads easily and melts into skin within seconds,leaving behind a smooth,hydrated base rather than any greasy residue. This makes it ideal for layering with other serums and moisturizers in your routine, which is exactly what a first-step activating serum should do—prep your skin so that everything applied afterward penetrates more effectively.
The application experience seems to vary slightly depending on how much product you use, and reviewers consistently mention that a little goes a long way. Most customers report using 2-3 drops or pumps for the entire face and neck,pressing it gently into skin rather than rubbing vigorously. One thing to note: several reviewers mention the bottle size confusion (some received 60ml instead of the listed 90ml), so double-check your product specifications before purchasing. The fermented ginseng extract and Korean herb complex give it a subtle herbal scent that most reviewers describe as pleasant and spa-like, though a few with scent sensitivities mentioned they could detect it initially before it faded.We appreciated that customers with sensitive skin reported no irritation or breakouts, and many noted their skin felt “strengthening and balancing” rather than stripped or tight. For best results, apply this immediately after cleansing on damp skin, before any treatment serums or actives in your routine.
How It Performed on Fine Lines, Dryness and Dullness

We found that customers consistently report noticeable improvements in all three areas this serum targets, though the timeline and degree of results varied based on skin type and age. According to reviews, the hydration benefits appear almost immediately—many users mention their skin feeling ”noticeably softer” and “more hydrated” from the first application, with one reviewer describing “immediate hydration, softness, and a subtle plumping effect.” For fine lines specifically,the feedback suggests more gradual betterment over consistent use.A 47-year-old reviewer noted that after approximately two weeks of use, her fine lines became “less visible,” while a customer with mature, post-menopausal skin emphasized that “over time it helps improve skin tone, texture, and overall radiance.” The 500-hour aged ginseng extract and vitamin C in the formulation work together to support skin’s resilience and brightness, which several customers described as achieving a “lovely glow” and “luminous” appearance that looks natural rather than artificially shiny.
The dullness-fighting performance stands out as perhaps the most universally praised aspect across customer reviews. One user who typically struggles with “dry and dull” skin reported that after about a month of use, their complexion became “so hydrated, plump and glowy,” expressing regret at not having before-and-after photos to document the change.Another reviewer specifically called out how their skin appeared “noticeably plumper, brighter & overall healthier” after six months of consistent use. What makes these results particularly engaging from a skincare perspective is that this serum functions as a first-step activating treatment—applied immediately after cleansing and before other serums—which customers say helps their subsequent products “penetrate better and work more effectively.” The lightweight, silky texture absorbs instantly without stickiness, creating what one mature-skinned reviewer described as “a beatiful hydrated base” that allows layering without heaviness. for those concerned about dryness specifically, reviewers with post-menopausal and mature skin found it “strengthening and balancing,” helping skin look “calmer, smoother, and more luminous,” which suggests the Korean herb extracts and fermented ginseng are delivering on their barrier-supporting properties.
Best Skin types for This Serum

Based on customer feedback and the serum’s formulation with fermented ginseng extract and Korean herbal complexes, we’ve found that this activating treatment works beautifully across multiple skin types, though it truly shines for specific concerns. According to reviewers, those with mature, dry, or dehydrated skin see the most dramatic results.One 52-year-old customer with post-menopausal skin shared that this serum feels “strengthening and balancing,” helping her skin look “calmer,smoother,and more luminous.” Many customers with dry skin report that the lightweight, silky texture delivers immediate hydration without any heaviness or greasiness, creating what they describe as a “plumped” and healthy-looking complexion. If you’re dealing with dullness or uneven texture, reviewers consistently mention improvements in radiance and skin tone—one user noted her complexion became “more even” after just two weeks of use.
We’ve also noticed that customers with combination skin appreciate how this serum absorbs instantly without leaving a sticky residue, making it easy to layer under other products and makeup. the formula’s barrier-supporting properties make it particularly valuable if you’re using active ingredients like retinoids or exfoliating acids, as several reviewers mention it helps their skin feel less stressed and more resilient. However, we should note that if you have very oily skin, you might find the formula’s hydrating focus more than you need, though some customers do use it successfully as a foundational step. The manufacturer positions this as suitable for skin concerns including dryness, dullness, and skin texture, and customer experiences largely confirm these claims. As with any new serum, we always recommend patch testing first, especially if you have sensitive skin, though reviewers generally describe this as gentle and well-tolerated across different skin types.

Q&A

When should I apply this in my routine?
This is a true first-step activating serum,which means you apply it immediately after cleansing and toning,before any other serums or treatments. It’s designed to prep your skin and help subsequent products absorb better.The typical order would be: cleanse → tone (if using) → Sulwhasoo First Care Activating serum → other serums → moisturizer. Many reviewers note that their entire routine seems to work better when they use this as their foundation step.
Is this suitable for mature or dry skin?
Yes, this serum is particularly well-suited for mature and dry skin types. Customer reviews consistently highlight that it works beautifully on post-menopausal, dry, and dehydrated skin, providing immediate hydration and a subtle plumping effect. The lightweight, silky texture absorbs quickly without feeling heavy or greasy, while still delivering the deep hydration mature skin needs. It also helps strengthen the skin barrier, which becomes increasingly important as skin ages and becomes more fragile.
Can I use this morning, evening, or both?
You can use this serum both morning and evening for maximum benefits. Reviewers who use it daily (twice a day) report the best results. It works beautifully under makeup according to multiple customers, causing no pilling or interference with foundation application. The lightweight texture makes it ideal for AM use, while its hydrating and barrier-supporting properties make it equally beneficial in your evening routine.
Can I use this with retinol or vitamin C?
Yes,this serum is generally compatible with active ingredients like retinol and vitamin C—actually,it contains vitamin C itself along with fermented ginseng extract. Many reviewers mention it helps support the skin barrier, which is especially beneficial when using potent actives like retinoids or exfoliating acids. Apply this first after cleansing, then follow with your retinol or other treatment serums. As always, introduce new products gradually and consider using retinol at night with daily SPF during the day.
How long before I see results?
Based on customer reviews,you can expect to see immediate benefits like improved hydration and softness within the first few applications. More noticeable improvements in skin texture,radiance,and evenness typically appear within 2-4 weeks of consistent use. For addressing fine lines, plumping, and overall skin health, reviewers mention seeing significant results around the 4-6 week mark and continuing improvement with ongoing use. One reviewer specifically noted visible improvements in fine lines and discoloration after just two weeks.
How much product should I use per application?
A little goes a long way with this serum. Reviewers consistently mention that even the mini travel size lasts surprisingly long because you only need a small amount per application.The texture is a mixture of lightweight liquid and oil that spreads easily across the face. Typically, 2-3 drops or about a nickel-sized amount is sufficient for the entire face and neck. The product absorbs instantly, so you’ll know quickly if you’ve used too much.
What are the key active ingredients?
The star ingredient is fermented ginseng extract that has been aged for 500 hours, which is Sulwhasoo’s signature technology. This fermentation process makes the ginseng’s beneficial compounds more bioavailable to the skin. the formula also contains Korean herbal extracts and vitamin C to target fine lines, dryness, and dullness. The fermented ginseng works to improve skin texture, radiance, and overall barrier health, while the vitamin C addresses brightness and preventative anti-aging concerns.
What’s the texture like and does it have a scent?
The serum has a lightweight, silky texture that’s a hybrid between a liquid and an oil. It absorbs instantly into the skin with no sticky or greasy residue, making it perfect for layering other products on top. Reviewers describe it as elegant and luxurious-feeling without being heavy. It does have a noticeable herbal scent from the ginseng and Korean botanical extracts, which customers describe as pleasant and spa-like. If you’re sensitive to fragrance, you may want to sample it first, though the scent dissipates quickly after application.
