When you started using glycolic acid on your face did you get freckles and discoloration more easily?

I know you are supposed to protect your skin from the sun when using lotions with glycolic acid, but I was out for a very short time yesterday and did not have any SPF on. This morning I think I am a little more freckled, and it happened much quicker than it normally would. I noticed about 6 months ago I had a little more discoloration on my face, or at least I thought so, and so now I am wondering if stripping away the outer, dryer, skin layer means sun damage happens faster.
