A Retrospective Survey to Assess the Skin Lightening, Skin Moisturization and Sensorial Properties of a Broad Spectrum Sunscreen Formulation in Indian Patients
Journal Title: INTERNATIONAL JOURNAL OF SCIENTIFIC STUDY - Year 2017, Vol 5, Issue 7
Abstract
Introduction: Indian people primarily use sunscreens to prevent tanning and maintain a fair complexion rather than preventing sunburns and cancers which are the internationally recommended reasons for use of sunscreens. Considering these factors, a broad spectrum sunscreen formulation with anti-tanning and skin lightening properties will be an ideal formulation for Indian skin types. Materials and Methods: A retrospective survey was conducted to assess the skin lightening, skin moisturization, and sensorial properties of a broad spectrum sunscreen formulation (octinoxate + diethylamino hydroxybenzoyl hexyl benzoate + bis-ethylhexyloxyphenol methoxyphenyl triazine + titanium dioxide, silicon dioxide, and dimethicone + diethylhexyl butamido triazone + melanostatine + tyrostat) in 30 patients at a single dermatology and cosmetology center at Amritsar. Both the patients and the treating physician rated the skin lightening, skin moisturization and sensorial properties of the sunscreen at 6 and 12 weeks. Results: The patient’s and physicians positive rating for skin lightening and skin moisturization had increased significantly at the end of 12 weeks compared to that of 6 weeks. The patients rating for sensorial properties at the end of 12 weeks were as follows: Non-irritation in 83.32% (n = 24), non-greasiness in 89.99% (n = 26), compatibility with other cosmetics in 90% (n = 27), non-interference with outdoor activity in 85.72% (n = 25), spreadability in 93.33% (n = 27), and sensation of softness and freshness in 89.99% (n = 26) at 12 weeks. Discussion: Indian skin types react differently to chronic ultraviolet exposure compared to Caucasian skin. Uneven skin tone due to persistent pigmentation and tanning are major concerns in Indian patients; therefore, it requires a broad spectrum sunscreen with additional skin lightening (anti-tanning) properties. The sunscreen used in this survey contains two skin lightening agents’ melanostatine and tyrostat which indicates why patients rating was positive for skin lightening effect for the sunscreen in this survey. It is also made in silicone base which imparts good sensorial properties. Conclusion: A broad spectrum sunscreen with skin lightening properties may increase the adherence of patients to use sunblock regularly. Long-term, comparative studies are required.
