Lovi Assistant explains
- Offers moderate moisturizing and treatment for your oily skin, with glycerin and honey providing hydration and improving overall skin condition, though it lacks targeted ingredients for oil control.

- Apply this moisturizer after cleansing and toning, but right before your SPF in the morning.
- Gently press a small amount into your skin and let it absorb fully.

Questions and answers
Why is Sulwhasoo First Care Activating Serum a weak match for oily skin?
This serum is a weak match for oily skin because it lacks targeted ingredients for oil control and contains alcohol, which may pose a slight irritation risk. Oily skin needs products that regulate oil production and minimize the appearance of pores using ingredients like Niacinamide, along with lightweight hydrators and soothing agents like Allantoin.
Which ingredients make this serum a poor fit for oily skin?
The alcohol in this serum may pose a slight irritation risk for oily skin, and the formula lacks targeted ingredients for oil control. Oily skin needs a product that is safe with no risk of irritation, effectively provides hydration and improves skin texture, and performs its intended function well, although it may not fully align with the primary needs of oily skin. A product of this type needs hyaluronic acid for optimal hydration, Niacinamide to help regulate oil production and minimize the appearance of pores, the absence of allergens, and soothing ingredients like Allantoin.
What does Water do for oily skin?
Water helps keep oily skin hydrated without adding grease or clogging pores. Keeping oily skin properly hydrated may also help balance oil production and reduce unwanted shine.
What does Butylene Glycol do for oily skin?
Butylene glycol helps deliver active ingredients deeper into the skin and is unlikely to clog pores, making it useful for keeping oily skin balanced and smooth. It helps other ingredients penetrate effectively while maintaining a lightweight feel.
Journal of Controlled Release, 2022European Journal of Pharmaceutics and Biopharmaceutics, 2008
Where does this serum go in a skincare routine for oily skin?
This treatment serum goes in the evening routine after cleansing and before moisturizing, though an oily skin type needs a product of this type that also includes targeted oil-control ingredients.
Can I use this serum with retinol, and in what order?
You can use this serum with retinol by applying the serum first to hydrate your skin before putting on your retinol. However, this product is a weak match for oily skin, so an oily skin type needs a product with targeted oil-controlling ingredients to manage shine.
How often should I use this serum?
This serum is used in the evening routine, but some treatments may also be used in the morning or twice a day. Because oily skin needs a product with targeted oil control and alcohol-free ingredients to avoid irritation, you should start slowly.
Can this serum clog pores, cause breakouts or purging for oily skin?
This serum is unlikely to cause breakouts or clog pores for oily skin, as reviewer complaints about potential breakouts are negligible. However, a product for oily skin should include targeted ingredients for oil control.
Can I use this serum around the eyes or on my body?
You can use this serum around the eyes, where the skin is particularly thin, and on your body. Because skin thickness varies across different body regions, hydrating ingredients like glycerin help maintain moisture and smoothness in delicate areas.
Is this serum fragrance-free and alcohol-free?
It has no fragrance and contains drying alcohol (alcohol).
What the research says
A single application of a moisturizing fluid containing hyaluronic acid 1%, glycerin 5%, and Centella asiatica stem cells extract significantly increased skin hydration by 29% and reduced transepidermal water loss at 24 hours compared to baseline and an untreated control site in twenty healthy women.
Clinical, Cosmetic and Investigational Dermatology, 2017Topical low-dose green tea extract reduces UVB-induced p53 expression and apoptosis in human skin keratinocytes compared to placebo.
Experimental Dermatology, 2009The emollient V0034CR significantly reduced TEWL compared to vehicle and vehicle plus glycerol, and significantly increased corneometry scores compared to vehicle and vehicle plus petrolatum in healthy volunteers with dry skin, demonstrating combined barrier function improvement from petrolatum and hydration improvement from glycerol.
Journal of Cosmetic Dermatology, 2020Ten days of treatment with a cream containing 20% glycerin significantly increased skin hydration measured by corneometer values in 17 healthy volunteers compared to a placebo cream, but showed no influence on transepidermal water loss or skin sensitivity to an irritating surfactant.
International Journal of Cosmetic Science, 2001Niacinamide/glycerin body moisturizers provided better rapid and prolonged improvement of cosmetic xerosis through functional improvement of stratum corneum barrier function compared to no treatment and conventional moisturizers in female subjects.

Why other moisturizers fit oily skin better
A panthenol-enriched mask improved skin hydration, regulated sebum, and reduced redness and TEWL across dry sensitive, oily sensitive, and oily acne skin subgroups with excellent tolerance and no adverse reactions.
Journal of Cosmetic Dermatology, 2024Gluconolactone chemical peels lower skin pH and transepidermal water loss while demonstrating seboregulatory properties in 16 female subjects.
Journal of Cosmetic Dermatology, 2023Combining 10% gluconolactone chemical peeling with oxybrasion or microneedle mesotherapy increased skin hydration and decreased sebum, pH, and TEWL in twenty-one Caucasian women, with no significant differences between the two methods.
