dc.description.abstractLatar belakang: Penuaan dini merupakan hilangnya secara perlahan kemampuan jaringan untuk memperbaiki diri yang berlangsung lebih cepat dari seharusnya yang dapat dihambat dengan menggunakan anti-aging, yaitu kosmetik yang mencegah tanda-tanda penuaan. Buah stroberi merupakan buah yang mengandung antioksidan yaitu vitamin C 60 mg per 100 g yang kerjanya menetralisir radikal bebas. Tujuan penelitian: Memformulasi krim dari konsentrat sari buah stroberi dan mengetahui efektivitas anti-aging pada kulit. Metode: Konsentrat sari buah stroberi dibuat dengan cara dijuicer dan difreeze dryer kemudian diformulasikan dalam krim dengan modifikasi dasar krim sunblock tipe m/a (propilen glikol, natrium edetat, TEA, vaselin, setil alkohol, asam stearat, gliseril monostearat, BHT, nipagin, parfum, aquadest) dengan konsentrasi konsentrat sari buah stroberi yaitu F0 (blanko), F1 (5%), F2 (7,5%), F3 (10%), dan F4 (krim Olay). Pengujian krim meliputi uji homogenitas, tipe emulsi, pengukuran pH, penentuan stabilitas selama penyimpanan 12 minggu pada suhu kamar, dan uji iritasi. Pengujian efektivitas anti-aging dilakukan terhadap formula F0 sampai F4 yang terdiri dari 15 orang. Pemakaian krim 2 kali sehari. Parameter yang diukur meliputi kadar air, kehalusan, pori, noda, keriput dan kedalaman keriput menggunakan skin analyzer pada kondisi awal dan setiap minggu selama 4 minggu. Hasil: Hasil homogenitas menunjukkan krim homogen. Hasil tipe emulsi menunjukkan tipe emulsi m/a. Hasil pengukuran pH F0, F1, F2, F3, dan F4 adalah 5,8; 5,5; 5,2; 4,9; dan 6,4. Semua krim stabil selama 4 minggu, tetapi pada penyimpanan 8 minggu terjadi perubahan warna pada F1, F2, dan F3 dari warna merah kecokelatan menjadi cokelat dan perubahan bau selama penyimpanan 12 minggu. Sediaan krim tidak mengiritasi kulit. Hasil efektivitas anti-aging diperoleh F3 memberikan hasil yang lebih baik daripada formula lain. Kesimpulan: Konsentrat sari buah stroberi dapat diformulasikan dalam krim anti-aging dan F3 (krim 10%) menunjukkan efektivitas anti-aging yang terbaik.en_US

Cream testing included homogeneity test, emulsion type test, pH measurement, determination of stability during 12 weeks of storage at room temperature, and skin irritation test. Anti-aging activity test was carried out on formula F0 to F4 which consisted of 15 volunteers. Cream was applied 2 times a day. Aging parameters measured included moisture, smoothness of skin, pores, spot, wrinkles and depth of wrinkles using a skin analyzer on the initial conditions and each week for 4 weeks of cream administration. Results: Homogeneity test results indicated that anti-aging creams was homogeneous, the type of emulsion was type O/W. pH measurement result of F0, F1, F2, F3, and F4 was 5.8; 5.5; 5.2; 4.9; and 6.4. All creams were stable for 4 weeks, but at 8 weeks of storage the color changed in F1, F2, and F3 from red-brown to brown and smell changed during storage of 12 weeks. Anti-aging cream did not irritated. F3 showed the best anti-aging effectivity compared to the other formula. Conclusion: Concentrated strawberry juice can be formulated in anti-aging creams and F3 (cream 10%) showed the best effectivity of anti-aging.en_US
