日間保養不只是擦上產品，更重要的是理解每一個步驟真正扮演的角色。妝前隔離與校色，可以協助修飾膚色並建立細緻底妝；面對紫外線時，則需要選擇具有明確防曬係數與測試標示的產品。當 SPF、UVA、防曬星級與廣效防護等資訊同時出現在包裝上，該如何正確判讀？今天，我們將從防曬標示出發，認識不同防護概念，並釐清 Y24 逆時．裸顏霜與 Y33 妍曦霧感防曬棒在日間保養中的不同定位。 A daytime routine is not simply about layering products—it is also about understanding the purpose of each step. A complexion primer can refine and balance the appearance of the skin, while UV exposure requires a product with clearly stated and tested sunscreen protection. When SPF, UVA, star ratings, and broad-spectrum claims all appear on the packaging, how should they be interpreted? This article explores the essentials of sunscreen labeling and clarifies the distinct roles of Y24 Rejuvenation Bare Skin Tone-Up Cream and Y33 UV & Ocean Protect All-in-One Sunscreen Stick 20g.
防曬標示的閱讀關鍵：如何判斷防護範圍？
The Essentials of Sunscreen Labels: How Is UV Coverage Evaluated?
I｜物理性與化學性防曬的配方機制 Physical and Chemical Sunscreen Formulation Mechanisms
物理性防曬主要運用二氧化鈦、氧化鋅等礦物性防曬成分，在肌膚表面形成防護；化學性防曬則透過有機防曬成分吸收紫外線能量，再將能量轉化並釋放。兩種機制各有不同的配方特性，實際質地、延展度與使用感受，也會受到粉體比例、基劑設計及整體配方影響。 Physical sunscreens primarily use mineral UV filters such as titanium dioxide and zinc oxide to provide protection on the skin’s surface. Chemical sunscreens use organic UV filters that absorb ultraviolet energy before converting and releasing it. Each mechanism has different formulation characteristics, while texture, blendability, and overall skin feel also depend on the complete formula.
II｜SPF：認識 UVB 防護係數 SPF: Understanding the UVB Protection Factor
SPF 是 Sun Protection Factor 的縮寫，主要用來表示產品對 UVB 的防護能力。UVB 與肌膚因日曬出現的泛紅、灼熱與曬傷反應密切相關。SPF 數字越高，代表經測試呈現的 UVB 防護能力越高，但防護比例並不會隨數字等比例增加。實際防護表現仍與塗抹量、均勻度、流汗情形及是否適時補擦有關。 SPF stands for Sun Protection Factor and primarily indicates a product’s tested level of UVB protection. UVB is closely associated with visible redness, burning sensations, and sunburn caused by sun exposure. A higher SPF indicates a higher tested level of UVB protection, although protection does not increase in direct proportion to the number. Actual performance also depends on application amount, even coverage, perspiration, and timely reapplication.
III｜UVA 防護：PA 與防曬星級的差異 UVA Protection: The Difference Between PA and Star Ratings
UVA 為長波紫外線，長時間累積曝曬與肌膚暗沉、彈性流失及光老化外觀有關。PA 通常以「+」號表示 UVA 防護等級；防曬星級則用來觀察 UVA 與 UVB 防護之間的相對平衡。不同標示採用的測試制度並不完全相同，因此選購時應以產品外盒所載明的實際檢測結果為準。 UVA is long-wave ultraviolet radiation, and accumulated exposure is associated with dullness, reduced elasticity, and visible photo-aging. PA commonly uses plus signs to indicate a tested UVA protection grade, while star ratings evaluate the relative balance between UVA and UVB protection. Because these labeling systems use different testing approaches, the verified information printed on the product packaging should remain the primary reference.
IV｜廣效防護與日常補擦的重要性 Broad-Spectrum Coverage and the Importance of Reapplication
廣效防護代表產品的測試結果涵蓋一定範圍的 UVA 與 UVB 防護。完整的日間防曬不能只看單一數字，也需要留意實際使用量與補擦頻率。長時間戶外活動、流汗、擦拭肌膚或妝容變化，都可能影響原有的防護覆蓋，因此便於攜帶與補擦的產品設計，也是維持日間防護的重要考量。 Broad-spectrum protection indicates that a product has been tested to provide coverage across a defined range of UVA and UVB radiation. Effective daytime protection depends not only on a single rating, but also on sufficient application and regular reapplication. Outdoor activity, perspiration, wiping, and changes in makeup may affect the original coverage, making portability and ease of touch-up important considerations.
日間保養應先釐清產品定位。提亮、校色與妝前打底，主要處理的是膚色與妝感；紫外線防護則必須依據產品經測試標示的防曬係數與使用方式。兩者可以搭配，但不能相互取代。因此，Y24 著重於隔離打底與裸顏修飾；需要日間紫外線防護時，則應搭配具備 SPF50+ 防曬標示的 Y33。 A daytime routine begins with understanding the purpose of each product. Brightening, tone correction, and makeup priming address the appearance of the complexion, while UV protection must be supported by tested sunscreen labeling and appropriate usage. These steps can complement one another, but they cannot replace one another. Y24 is therefore positioned as a complexion-enhancing primer, while Y33 provides SPF50+ sunscreen protection whenever UV defense is required.
隔離打底與防曬對策：建立完整日間步驟
Priming and Sun Protection: Building a Complete Daytime Routine
I｜Y24 逆時．裸顏霜：隔離、校色與妝前打底 Y24 Rejuvenation Bare Skin Tone-Up Cream: Priming and Tone Correction
Y24 逆時．裸顏霜以提亮膚色、修飾暗沉與妝前打底為主要定位。滑順質地可均勻延展於肌膚，單獨使用時呈現自然裸顏光澤，也可作為後續底妝前的隔離打底。Y24 未標示防曬係數，因此不能取代具有明確 SPF 標示的防曬產品。 Y24 Rejuvenation Bare Skin Tone-Up Cream is designed to brighten the complexion, soften the appearance of dullness, and prepare the skin for makeup. Its smooth texture spreads evenly, creating a natural bare-skin glow when worn alone or a refined base beneath makeup. Y24 does not carry an SPF rating and should not replace a sunscreen product with verified UV protection.
Y33 妍曦霧感防曬棒採用純物理性防曬配方，外盒標示 SPF50+ 與防曬星級 ★★★，提供日常通勤及戶外活動所需的紫外線防護。棒狀設計方便直接塗抹，也便於隨身攜帶與適時補擦，使防曬更容易融入日常生活節奏。 Y33 UV & Ocean Protect All-in-One Sunscreen Stick 20g features a purely physical sunscreen formula. Its packaging states SPF50+ protection with a ★★★ star rating for daily commuting and outdoor activities. The portable stick format allows direct application and convenient reapplication throughout the day.
III｜三色修容：依照膚色與部位自由搭配 Three-Shade Contouring: Flexible Color Placement for Every Complexion
Y33 提供三款不同色號，可依照原生膚色、臉部部位及妝感需求自由運用。3號 蜜桃色／PEACH 可修飾暗沉並提升紅潤氣色；5號 膚色／SAND 可自然提亮並與原生膚色融合；7號 健康色／TAN 可均勻色澤，呈現自然健美光采。三色並非合併於同一支產品，而是可分別選用，也可搭配不同部位共同使用。 Y33 is available in three individual shades that can be selected according to natural skin tone, facial area, and desired makeup effect. No. 3 Peach helps soften dullness and enhance a rosy appearance. No. 5 Sand provides natural brightening and blends with the complexion. No. 7 Tan evens the overall tone for a healthy-looking glow. The three shades are offered separately and may be used individually or combined across different facial areas.
IV｜霧感質地：妝前使用與日間補擦 Matte Texture: Before-Makeup Application and Daytime Touch-Ups
Y33 採用乾爽不黏膩的棒狀質地，輕抹即可均勻延展，降低傳統物理性防曬容易顯得厚重的使用感。可於底妝前均勻塗抹，也可依照當下妝容狀態，以少量、多次的方式輕柔補擦，使防護與修容更自然地融入日間妝感。 Y33 features a dry, non-sticky stick texture that glides evenly across the skin, offering a more refined alternative to the traditionally heavy feel of physical sunscreen. It can be applied evenly before makeup or gently layered in small amounts for daytime touch-ups according to the condition of the makeup.
V｜Ocean Protect：兼顧日間防護與環境理念 Ocean Protect: Daytime Protection with Environmental Consideration
除了 SPF50+ 防護與三色修容設計，Y33 亦融入 Ocean Protect 海洋友善理念。從日常通勤到戶外活動，在維持紫外線防護與妝感修飾的同時，也將對海洋環境的溫柔考量納入產品設計之中。 In addition to SPF50+ protection and three complexion-enhancing shades, Y33 incorporates an Ocean Protect concept. From daily commuting to outdoor activities, the design brings together UV protection, tone correction, and thoughtful consideration for the marine environment.
