Eczema Treatment Care

Ok, I used to break out and when I did, I was left with very dark acne scars and I have brown skin (Philippines) and so the scars are very noticeable to see. I am 21 yrs old and back when I was 15, I never wore sunscreen or moisturizer while I had makeup on so, I have a very uneven skin tone due to sun damage and I’m still suffering from it. I use Olay Total Effects Night Firming Cream to get the firmness back on my face and stuff and in the morning, I use Ambi Exfoliating Wash, and then I use Bio Oil for my scars and to even out skin tone. But I need a moisturizer with SPF 30 coz I don’t want the sun to damage my skin even more. Do you think, Bio Oil is enough for moisturizer though? and I’ll just use sunscreen? I am only allowed to use the brand PRESUN from Rite Aid coz I’ll suffer from Contact Dermatitis if I use other products, I’ve been to the dermatologist when I had a bad reaction from a sunscreen or sunblock and I was told that Presun is the only one I can use. What do you all suggest for my moisturizer with SPF 30? Thanks in advance
