The full review.
The idea is deceptively simple: if a sunscreen’s base is mostly water anyway, why not replace that water with something that actually does something for the skin? Numbuzin’s No. 1 Clear Filter Sun Essence takes this premise and runs with it, using 20.55% licorice root water, 15% centella asiatica extract, and 14.25% houttuynia cordata extract as the foundational liquid base. That is nearly fifty percent of the formula dedicated to calming, anti-inflammatory botanicals before you even get to the UV filters.
This is not merely a marketing gimmick. These are three of the most well-studied anti-inflammatory plant extracts in Asian skincare science, each with documented mechanisms of action. Licorice root provides glabridin, a tyrosinase inhibitor that addresses hyperpigmentation. Centella asiatica delivers madecassoside and asiaticoside, compounds shown to promote collagen synthesis and reduce redness. Houttuynia cordata, sometimes called heartleaf, offers antioxidant and anti-inflammatory properties that Korean dermatology has valued for decades. Together, they create a base that actively works to calm and protect the skin rather than simply holding the UV filters in suspension.
The UV filter system itself is thoroughly modern. Ethylhexyl Triazone, Terephthalylidene Dicamphor Sulfonic Acid (Mexoryl SX), Diethylamino Hydroxybenzoyl Hexyl Benzoate (DHHB), Bis-Ethylhexyloxyphenol Methoxyphenyl Triazine (Tinosorb S), and Polysilicone-15 — this is a five-filter cocktail that covers both UVA and UVB with excellent photostability. Unlike formulas built around avobenzone, which degrades under UV exposure and needs to be stabilized, these newer-generation filters maintain their protective capacity throughout the day. The PA++++ rating, the highest possible under the Japanese/Korean system, confirms robust UVA protection.
The texture is where this sunscreen earns its devoted following. It is genuinely essence-like — watery, almost weightless, with a slight greenish tint that vanishes on contact with skin. There is no drag during application, no white cast afterward, no greasy residue that announces to the world that you are wearing sunscreen. Within seconds of application, the finish settles into a natural, dewy glow that looks like good skin rather than a protective layer. For anyone who has struggled to find a sunscreen that does not compromise the look and feel of their morning skincare routine, this is a revelation.
Niacinamide makes an appearance mid-formula, adding brightening and barrier-supporting properties that complement the botanical base. An eight-type hyaluronic acid complex provides layered hydration at different molecular weights — standard sodium hyaluronate for surface moisture, hydrolyzed forms for deeper penetration, and a crosspolymer that creates a sustained-release moisture depot. For a sunscreen, this is an unusually generous hydration system.
Under makeup, the performance is excellent. The essence absorbs cleanly without leaving a tacky layer, so primers and foundations apply smoothly on top. Users report no pilling or separation throughout the day, though there is a caveat — applying the sunscreen immediately over heavier serums or oils without allowing absorption time can cause some balling. The solution is simple: let your skincare settle for a minute or two before applying.
The limitations are practical rather than formulation-related. Fifty milliliters is not a lot of sunscreen, especially when you are applying the recommended two-finger-length amount daily. At roughly eighteen dollars, you are looking at a monthly repurchase, which adds up over time. This is typical of Korean sunscreens — elegant texture comes at the cost of smaller packaging — but it is worth factoring into the value calculation.
For very dry skin in winter, this sunscreen alone may not provide enough moisture. It layers well over a richer moisturizer, but by itself, it is better suited to combination, normal, and oily skin types that appreciate the lightweight feel. In warmer months, it is a perfect standalone option for all but the driest skin.
Numberzin is still a young brand — founded in 2019, with this product launching around 2023. There is no decades-long track record to point to, no body of independent clinical research on the specific formula. What exists is a smart, well-constructed product built with ingredients that are individually well-validated, packaged in a texture that makes daily sunscreen use feel like a pleasure rather than a chore. The formula itself speaks to a team that understands modern sunscreen chemistry and is not cutting corners on either the UV protection or the skincare components.
For anyone in the market for an elegant daily sunscreen that calms sensitive skin, leaves no white cast, plays nicely under makeup, and treats the UV protection step as an opportunity to deliver skincare benefits — this is one of the strongest options currently available in the K-beauty space.

The science.
The Science
This sunscreen uses a botanical base backed by research. Centella asiatica at 15% contains madecassoside and asiaticoside, triterpenoid saponins studied for wound-healing and anti-inflammatory effects. A 2012 study in the International Journal of Molecular Sciences shows madecassoside inhibits the NF-kB inflammatory pathway and promotes type I collagen synthesis—helping calm irritation and protect against UV-induced collagen degradation.
Glycyrrhiza glabra (licorice) root water at 20.55% provides glabridin, which inhibits tyrosinase activity and melanin transfer. Research in the Journal of Agricultural and Food Chemistry (2003) confirmed glabridin inhibits UVB-induced pigmentation in vivo at concentrations as low as 0.1%. This makes it an appropriate ingredient for sunscreens targeting UV-induced hyperpigmentation prevention.
The UV filter system uses five modern organic filters. Tinosorb S (Bis-Ethylhexyloxyphenol Methoxyphenyl Triazine) is a broad-spectrum filter that absorbs UVA and UVB and stabilizes other less photostable filters in the system. DHHB (Diethylamino Hydroxybenzoyl Hexyl Benzoate) provides UVA I protection (340-400nm), the wavelength range most responsible for photoaging. A 2007 study in Photochemical & Photobiological Sciences shows Tinosorb S works synergistically with complementary filters to achieve higher SPF than each filter alone.
The eight-type hyaluronic acid complex uses different molecular weights to target different skin layers. Hydrolyzed hyaluronic acid (low MW, <10 kDa) penetrates deeper into the epidermis, while sodium hyaluronate crosspolymer forms a sustained-release reservoir on the surface.

Dermatologist Perspective
Dermatologists know sunscreen compliance depends on cosmetic elegance as much as SPF numbers; patients use sunscreens they enjoy wearing daily. Board-certified dermatologists note this formulation addresses the two main reasons patients skip sunscreen: discomfort (white cast, heaviness, stinging) and irritation on sensitive skin. The modern UV filter system is photostable and well-tolerated, the calming botanical base suits redness-prone and post-procedure skin, and the fragrance-free formulation reduces sensitization risk. Dermatologists note that PA++++ ratings come from controlled laboratory conditions; real-world protection depends on application amount and reapplication frequency.
Where it fits in your routine.
Apply generously as the last step in your morning skincare routine, after moisturizer and before makeup. Use about two finger-lengths of product for the face, neck, and ears. Let the sunscreen set for 5-10 minutes before applying makeup or going outside. Reapply every 2 hours during extended outdoor sun exposure, or after swimming or heavy perspiration. For office days with minimal sun exposure, one morning application and a midday touch-up before going outside works.
At about $18 for 50 ml, this sunscreen costs roughly $10.60 per fluid ounce. This price exceeds drugstore options but stays competitive in the K-beauty premium sunscreen category. High botanical extract concentrations, a modern UV filter system, and an eight-type HA complex show real formulation investment. However, the 50 ml size requires monthly repurchasing for proper application, so daily use costs $200+ annually. The value is strong for users who want elegant texture and skin-calming benefits. Users seeking only adequate UV protection can find cheaper options in larger formats.
This sunscreen works for people who want a daily formula that doesn't feel like sunscreen. It suits sensitive, redness-prone, or combination skin that reacts to white cast, heaviness, or irritation in other formulas. It is ideal for K-beauty enthusiasts who treat sun protection as skincare, makeup wearers needing a smooth base, and anyone with hyperpigmentation concerns wanting treatment and protection in one product.
The 50 ml format makes this expensive for body application or frequent reapplication during outdoor activities, which limits budget-conscious users needing high-volume daily sunscreen. It suits those who prefer mineral/physical sunscreens for philosophical or regulatory reasons. Users in extreme heat and humidity who need a fully matte, sweat-resistant sport sunscreen also use this.

Common myths.
Chemical sunscreens always irritate sensitive skin.
Modern chemical filters like Tinosorb S and DHHB are well-tolerated and cause less irritation than older filters like oxybenzone. This formula reduces irritation by embedding those filters in a base of centella, licorice root, and houttuynia cordata extracts.
The light texture means this sunscreen provides less protection than thicker formulas.
SPF uses a standardized application density (2mg/cm²) regardless of texture. This essence-type sunscreen provides SPF 50+ PA++++ protection at the recommended amount. Application amount determines protection, not a thicker texture.
FAQ.
Does Numbuzin No. 1 Sun Essence leave a white cast?
This is a purely chemical (organic) sunscreen. It has no mineral filters like zinc oxide or titanium dioxide, so it leaves no white cast. The formula has a faint greenish tint that disappears when applied, leaving a natural dewy finish for all skin tones.
Is Numbuzin sunscreen good for sensitive skin?
This formula targets sensitive skin. Botanical extracts make up nearly 50% of the base: 20.55% licorice root water, 15% centella asiatica, and 14.25% houttuynia cordata. These anti-inflammatory ingredients buffer the chemical UV filters. The formula is fragrance-free and alcohol-free.
Can I wear makeup over Numbuzin No. 1 Sun Essence?
The lightweight essence texture layers well under makeup. Wait 5-10 minutes for the sunscreen to set before you apply primer or foundation. Users report no pilling or separation when layered correctly, but pilling occurs if you apply it directly over certain heavy serums.
How often should I reapply Numbuzin sunscreen?
Reapply this sunscreen every 2 hours during continuous sun exposure, or right after swimming or heavy sweating. For indoor office days with minimal sun exposure, one morning application plus touch-ups before extended outdoor time works.
What UV filters does Numbuzin No. 1 Sun Essence use?
This sunscreen uses a modern photostable filter system: Ethylhexyl Triazone (Uvinul T 150), Terephthalylidene Dicamphor Sulfonic Acid (Mexoryl SX), Diethylamino Hydroxybenzoyl Hexyl Benzoate (DHHB/Uvinul A Plus), Bis-Ethylhexyloxyphenol Methoxyphenyl Triazine (Tinosorb S), and Polysilicone-15 (Parsol SLX). These newer-generation filters show superior photostability compared to older filters like avobenzone.
