Lightweight, Quick-Drying, Broad-Spectrum, Anti-Aging Sunscreen oh!oh! RK Defense Sunscreen 45g (with 3,000ppm MSR™ Blend, B-Circadin™ & Defensil®-Soft Pres)
oh!oh! RK Defense Sunscreen is a daily sunscreen with SPF50+ PA++++, which helps protect the skin from UVA/UVB rays, while also reducing the effects of blue light, infrared radiation, and environmental factors that can accelerate photoaging.
The product uses a broad-spectrum UV filter system combined with intelligent protective film technology, which helps the sunscreen layer distribute more evenly on the skin's surface, limiting the phenomenon of film breakage during use. The lightweight, easy-to-spread texture quickly stabilizes on the skin, creating a dry, non-sticky finish suitable for hot and humid climates.
The formula is also supplemented with Niacinamide, MSR™ Blend, an antioxidant system, and soothing ingredients, which help support the skin's protective barrier, reduce the effects of oxidative stress from sunlight, and maintain a healthier, smoother skin surface with daily use. The natural pink tint helps correct dullness, bringing a brighter, more radiant, and vital complexion.
Main Ingredients and Uses:
1. Broad-spectrum UV filter system
The formula uses a broad-spectrum UV filter system with a combination of Zinc Oxide, Bis-Ethylhexyloxyphenol Methoxyphenyl Triazine, Ethylhexyl Triazone, and Polysilicone-15, helping to protect the skin from both UVA and UVB rays. UVB rays are typically associated with redness and sunburn on the skin's surface, while UVA rays can penetrate deeper, promoting oxidative stress and contributing to the degradation of collagen, elastin, and skin elasticity over time.
The product helps enhance skin protection in daily activities, especially for skin prone to dullness, hyperpigmentation, or those undergoing treatment routines. Simultaneous protection against UVA and UVB is an important foundation for limiting signs of photoaging such as uneven skin tone, rough surface, fine lines, and reduced firmness.
2. Smart sunscreen film system
The smart sunscreen film system was developed to help UV filters spread more evenly on the skin's surface before the film fully stabilizes. This helps the sunscreen layer, once set on the skin, become thin, even, and reduces the heavy feeling.
Thanks to the structural support and film-forming system, the product is easy to spread, quickly stabilizes on the skin, and maintains a more comfortable protective layer for daily use.
3. 3,000ppm MSR™ Blend
MSR™ Blend is a peptide complex including Acetyl Hexapeptide-8, Acetyl Tetrapeptide-2, and Acetyl Octapeptide-3, added to help protect the skin from signs of photoaging caused by UV rays and accumulated oxidative stress every day.
Photoaging is not only manifested in wrinkles but also involves a decrease in elasticity, a rougher skin surface, and less stable skin quality over time. This peptide group helps improve the appearance of fine lines, contributes to maintaining firmness, and helps the skin surface look smoother and healthier with regular use.
4. B-Circadin™
B-Circadin™ is an active ingredient that helps protect the skin from oxidative stress and adverse effects from the daily environment. In sunscreen, this ingredient supports the skin's protective mechanism against sunlight, pollution, and factors that can make the skin dull, tired, or lack vitality.
The presence of B-Circadin™ means the formula not only offers broad-spectrum sun protection but also helps maintain a brighter, healthier, and more stable appearance for the skin when exposed to urban environments.
5. Defensil®-Soft Pres
Defensil®-Soft Pres is a complex that helps soothe and strengthen skin stability, especially suitable for skin that is easily sensitive, irritated, or frequently exposed to sunlight, dust, and air conditioning.
This ingredient helps reduce feelings of tightness and discomfort, while supporting the skin's protective barrier to maintain a more balanced state. When combined with a broad-spectrum sun protection system and antioxidant active ingredients, Defensil®-Soft Pres makes the product more suitable for daily use on various skin types.
6. Iron Oxides
Iron Oxides (CI 77491) create a natural light pink tint, helping to correct dullness and provide brighter skin after application. Unlike a white cast, the pink tint in the formula makes the skin surface look more radiant and vital, suitable for daily use or before makeup.
In addition to its role in correcting skin tone, Iron Oxides are often used in tinted sunscreen formulas to help enhance protection against visible light. This is an important factor for skin that is prone to tanning, dullness, or at risk of hyperpigmentation with frequent exposure to sunlight, blue light, and urban environments.
7. Niacinamide & skin stability support system
Niacinamide is a multi-tasking active ingredient often used in skincare formulas due to its ability to support the strengthening of the skin's protective barrier, improve dull complexion, and help the skin look healthier. In the sunscreen formula, Niacinamide contributes to supporting the skin against the effects of sunlight, pollution, and environmental stress, while helping to maintain a more stable skin surface with daily use.
In addition, Hydroxyacetophenone, Dipotassium Glycyrrhizate, Adenosine, Albatrellus Confluens Extract, and Lespedeza Capitata Leaf/Stem Extract provide antioxidant and soothing properties. Hydroxyacetophenone helps reduce the effects of oxidative stress and low-level inflammatory reactions on the skin's surface. Dipotassium Glycyrrhizate, derived from licorice, is suitable for sensitive skin due to its ability to soothe discomfort. Adenosine helps improve the appearance of fine lines, while plant extracts help the skin maintain a more stable state against environmental aggressors.
Instructions for use:
Use in the morning, as the last step of your skincare routine and before makeup.
Take an adequate amount of sunscreen and apply it evenly over your entire face, neck, and areas of skin that are easily exposed to sunlight.
Apply approximately 15–20 minutes before going outside for the sunscreen layer to stabilize on the skin.
Reapply every 2–3 hours when outdoors, sweating heavily, or after wiping/washing your face.
