I have a combination skin type, and my T-zone becomes darker sometimes. I have started using aloe vera gel mixed with turmeric, lemon juice, and gram flour as a face pack, and I use it daily. Is it safe to use this pack daily? Actually, there is some tingling sensation while I apply it, and when I wash my face, some redness occurs on my face, but after some time, it fades away. Should I continue using it? It is showing some good results. Are there any serious side effects of aloe vera gel?
