I'm 33 and just in the last couple of months I've developed really deep laughter lines. They're very noticeable even with a straight face. There is a permanent crease, which is lightly worse on the left side.
I've been using a collagen serum and retinol moisturiser at night and a collagen moisturiser in the morning for a while now but haven't noticed much improvement. Is there anything else I can do? I've been reading up online, and it says it's usually due to volume loss in the cheeks and round the nose, but apart from getting filler/botox, is there anything else I can try?
