Innovative organic sunscreen formulation for sensitive skin: Potential game-changer in sun protection
If you struggle with sensitive skin, finding a sunscreen that effectively protects your skin without causing irritation can be a challenge. A recent study conducted at Kangnam Sacred Heart Hospital of Hallym University in Seoul, Korea, offers promising insights into a novel organic sunscreen formulation specifically designed for sensitive skin. This innovative product aims to address the unique needs of those who struggle with discomfort from conventional sunscreens.
Key Takeaways
Novel, organic filter-based sunscreen demonstrated improvements in skin sensitivity and hydration in 15 research subjects.
Highlights potential of a new sunscreen formulation for those with sensitive skin, prone to irritation from traditional sunscreens.
The Study: Design and Outcomes
The clinical trial, conducted between December 2022 and July 2023, involved 15 participants (13 females and 2 males) with an average age of 33. All participants experienced sensitive facial skin symptoms for at least six weeks. They applied the SPF43 and PA+++ sunscreen, branded as Bariderm Shield Cream MD, twice daily for eight weeks.
Key assessments included:
Sensitive Scale-10 (SS-10) Questionnaire
Measurements of transepidermal water loss (TEWL) and stratum corneum hydration (SCH)
Clinical evaluation of erythema, papules, pustules, and scaling
At baseline, participants reported high skin sensitivity and discomfort. However, significant improvements were observed at week four, with continued progress through week eight.
Results: A New Standard for Sensitive Skin Protection
Improved Skin Hydration and Barrier Function
TEWL levels decreased significantly, indicating a stronger skin barrier (14.28 ± 5.55 at four weeks and 12.33 ± 4.10 at eight weeks).
SCH increased consistently, reflecting enhanced skin moisture.
Reduced Sensitivity and Irritation
SS-10 scores dropped from 33.30 ± 24.54 at baseline to 25.33 ± 17.65 by week eight.
Erythema and other skin irritations decreased significantly, with erythema showing marked improvement as early as week four.
High Patient Satisfaction
Participants praised the product for its non-irritating formula, absence of a sticky texture, and lack of white residue—common drawbacks of inorganic sunscreens.
Safety and Patch Test Results
Among 30 individuals tested, 96.67% had no adverse reactions to the sunscreen. Only one participant experienced a mild irritant reaction, which resolved within 96 hours.
The Formula: Gentle Yet Powerful
The sunscreen contains a blend of organic UV filters, including bis-ethylhexyloxyphenolmethoxyphenyltriazine, diethylaminohydroxybenzoylhexylbenzoate, and ethylhexyltriazone. These ingredients are recognized for their anti-inflammatory properties and broad-spectrum UV protection. Additionally, moisturizing agents like ceramides and panthenol enhance the skin barrier while maintaining hydration.
A Step Forward in Dermatology
This study underscores the importance of developing sunscreens tailored to sensitive skin. By minimizing irritation and maximizing patient comfort, such formulations encourage consistent use, which is critical for effective sun protection. While the small sample size and absence of a control group highlight the need for further research, the results are a promising step forward.
As sunscreen technology evolves, products like Bariderm Shield Cream MD offer hope for those with sensitive skin, ensuring they can enjoy the benefits of sun protection without compromising comfort. From my research, the product does not appear to be on the market yet. But I would be on the lookout for this from the brand Uriage Eau Thermale in 2025.
