According to a 2023 survey on sunscreen use released by the Korea Consumer Agency, 68% of consumers check only the SPF number when buying sunscreen and do not look at the UVA protection rating. UVA penetrates deep into the skin and causes pigmentation and skin aging, so the SPF number alone cannot provide complete protection. This is why choosing a single sunscreen requires more careful attention than many people expect.
Why SPF and PA should be checked together
When choosing sunscreen, it is important to make a habit of checking both SPF and PA. SPF shows how well the product blocks UVB, which causes sunburn and acute skin damage, while PA separately measures protection against UVA, the main cause of skin aging and pigmentation.
The PA rating is an independent UVA protection indicator developed in Japan and is divided into four levels from PA+ to PA++++ based on PPD, which measures persistent pigment darkening caused by ultraviolet rays. Among them, PA++++ corresponds to a PPD value of 16 or higher and is considered the highest protection level for daily use, blocking more than 94% of UVA.
Both indicators need to be high in order to help prevent burns caused by UVB and long term skin damage caused by UVA at the same time. No matter how high the SPF is, if the PA rating is low, the sunscreen is only doing half the job. The key to choosing sunscreen is looking at SPF and PA together.
Why hybrid formulas are gaining attention
The growing interest in hybrid sunscreen is not just a trend, but the result of advances in formula technology. Organic sunscreen filters, also known as chemical filters, absorb ultraviolet energy in the inner layers of the skin and convert it into heat. They usually have a lightweight texture, absorb quickly, and are suitable for layering under makeup. However, it is important to consider that they take 15 to 20 minutes to become active after application and may irritate sensitive skin.
Inorganic sunscreen filters, also known as physical filters, work by scattering ultraviolet rays on the outer layer of the skin, and their strength lies in their stable performance across a broad range of wavelengths. Hybrid formulas that combine both types of filters compensate for the weaknesses of each and create a synergistic effect that delivers much higher SPF performance than simply adding individual ingredients together.
According to an analysis by Croda Beauty, hybrid formulas that blend organic and inorganic sunscreen filters can achieve a significantly higher sun protection factor than inorganic filters used alone. Tone up sunscreens continue to establish themselves as multifunctional formulas that provide UV protection and skin tone correction at the same time based on this hybrid design.
How to use YURICO5 Pocket Tone Up Sunscreen in daily life
After finishing morning skin care and getting ready to go out, there are days when you want one sunscreen to handle both UV protection and a smoother looking skin texture. YURICO5 Pocket Tone Up Sunscreen was created from this everyday need.
Developed with cosmeceutical based technology, it leaves the skin texture looking more even after application, making it easy to use as a base step before makeup. In actual use, this product is often mentioned for the following points.
- It feels moisturizing without stickiness, so it is comfortable to use even in summer.
- After applying it, the skin texture looks more refined, making it perfect before foundation.
- Even on days when my skin feels sensitive, I can use it comfortably without irritation, so I keep reaching for it.
- The pocket size makes it easy to carry in a bag and reapply while out.
YURICO5 plans its products under the principle of using premium level ingredients at a reasonable price and has carefully managed the entire process from formula research to product development. The answer to how UV protection and natural tone correction can work together in daily life is contained in this product.
Choosing one sunscreen has become this complex because, paradoxically, our understanding of the skin has become that much deeper. SPF that blocks UVB, PA that protects against UVA, and attempts to include texture and tone correction in one product are not simply about convenience, but come from accumulated skin science. The direction in which YURICO5 designed its tone up sunscreen based on cosmeceutical expertise is part of that same progression. A choice that considers both protection performance and everyday ease of use is becoming the new standard for sunscreen.
