Sulwhasoo is a luxury Korean skincare brand that's recently become popular worldwide. The brand claims to sell "Targeted Solutions For All Skin Concerns."
But does Sulwhasoo use research-backed ingredients for reducing wrinkles and improving skin? Does the brand use any unhealthy additives? How do real users rate its effects? And how does Sulwhasoo compare to other luxury skincare brands?
In this article we'll answer all of these questions and more, as we analyze the ingredients in Sulwhasoo's most popular product (First Care Activating Serum) to give our take on whether or not it's likely to be effective.
We'll also share our concerns with the company's research claims, feature real user reviews, and compare Sulwhasoo to other luxury skincare brands like Depology.
Key takeaways:
- Highly potent formulation
- Contains fragrance ingredients we consider unhealthy
- We do not currently recommend Sulwhasoo
Ingredient Analysis
The ingredients in Sulwhatsoo First Care Activating Serum VI are shown below:
Panax ginseng root extract is the key active ingredient, and this root was shown to have anti-aging and skin whitening effects in a 2022 .
While ginseng is the ingredient that the brand centers much of its marketing on, there are other active ingredients in this formulation with research backing.
Nelumbo nucifera flower extract is clinically shown to have anti-aging effects, as we documented in our Rare Beauty Blush reviews article.
Madecassoside is another ingredient with skin whitening effects, having been shown in a medical review published in the Molecules journal to inhibit melanin synthesis.
Ascorbic acid, better known as vitamin C, is to significantly reduce wrinkles when applied topically.
While this formulation is impressive in regard to potential anti-aging effects, it also contains several ingredients that we consider to be questionable from a health perspective.
Fragrance is included, and a on fragranced consumer products published in the Air Quality, Atmosphere & Health journal concluded the following:
“Results of this study provide compelling evidence that everyday fragranced products can impose serious risks to human health, environmental quality, businesses, and society.”
Linalool, citronellol, citral and geraniol are additional fragrance compounds.
Overall, we consider Sulwhasoo likely to be effective for anti-aging, but we do not currently recommend this product due to the fragrance ingredients described above.
Questionable Research Citations
The First Care Activating Serum product page has a number of research call-outs, such as the suggestion that the product increases skin hydration by 14.5%.
However, the fine print for this claim has the below citation:
There is no link to the study, and we can't find any clinical trials on any Sulwhasoo products in peer-reviewed journals, so we'll assume this is a privately-funded and unpublished clinical study.
As we've stated in many other Illuminate Health articles, we recommend that consumers entirely disregard clinical claims based on research not published in peer-reviewed journals, due to the high risk of bias.

Sulwhasoo vs. the Competition
Here's our take on Sulwhasoo versus other luxury skincare brands:
Depology
Matrixyl 3000 (the brand's best-seller) has a similarly potent formulation but no unhealthy additives in our view, as we documented in our Depology reviews article.
Winner: Depology
VouPre
Like Sulwhasoo, contains many research-backed active ingredients, and some inactive ingredients we consider unhealthy. Significantly more expensive (with some products pushing $1,000).
Winner: Sulwhasoo
DRMTLGY
Needle-Less Serum should be similarly effective to First Care Activating Serum. Contains some inactive ingredients we consider unhealthy (two preservatives in combination), but we consider these ingredients to be better than the fragrance additives in Sulwhasoo.
Winner: DRMTLGY
