Physical sunscreen with high zinc oxide in India?

Check out these 2 sunscreens with high zinc oxide in India:

Dermalogica Super Sensitive Faceblock SPF 30 (9.2% zinc oxide, 6.7 % titanium dioxide) a non-chemical based sunscreen. It is available at medplusbeauty.com and Dermalogica outlets in India at Rs. 3490 for 50 ml.

Clinique Super City Block  Oil-free Daily Face Protector SPF 40 contains 8.8% zinc oxide but is not an entirely physical sunblock. It is available from Indian online shopping websites and Clinique counters at approximately Rs. 1500 for 40 ml.

Do  we  need  to  double  cleanse  even  after  using  physical  sunscreens  and  lotions  like  Lacto  Calamine  or  Calak  lotion (Shalaks  Pharmaceuticals)?And  can  the  Dermalogica  and  Clinique  sunscreens  be  used  on  oily  and  acne  prone  skin?

Between the two, Clinique Super City Block  Oil-free Daily Face Protector SPF 40 is safer for oily acne prone skin. Dermalogica Super Sensitive Faceblock SPF 30 is not exactly targeted at acne prone skin but sensitive skin.

Irrespective of what products you use, double cleansing can always be added as an additional cleansing step to remove all traces of all products. Assuming it suits your skin.
