Dear Naresh
You have based your query on three things shat dhaut ghrit, rose water and aloe vera. Well dear self use of medicines is never recommended be it any as the causative factor or prakriti of the person may differ. Shat dhaut ghrit is made by washing butter with tap water for one hundred times, by doing so the excess greasy part of butter is washed off and it becomes an ointment. As it is made of butter which is known as builder of body or tonic so its nutrient effect is well established. It becomes one of the best moisturisers. But if your skin is already acutely oily and your prakriti is Kaphaj and your Kaph dosh is vitiated then such thing are not recommended till vitiation becomes normal. Yes when all these factors are favourable it adds to gain wrinkle free glowing skin.

Rose water is like a coolant refreshing and gives a good feeling besides being a mood elevator. Internally it balances Pit and is mildly laxative. A mixture of rose water lemon juice and glycerine is an age old skin remedy for glowing skin. It becomes a very good moisturiser.

Aloe vera is best liver tonic and laxative when taken internally. It has many more anti oxidant properties. Being in the form of gel in natural state its moisturising effect and anti oxidant effect helps skin look young and glowing.

I can not specify mantras, but pure , peaceful and happy mind is the base of good health as in our case it is mind over body, and mantras create an atmosphere of faith and self confidence joined with divine blessings. I have full faith in Gyatri mantra,and mritunjaya mantra, if you believe you can chant the same.
