The No7 Prime Forever™ Preservation Serum feels lightweight and absorbs quickly without any stickiness. My skin feels more hydrated and looks a bit smoother and brighter with regular use. It works well under moisturiser and SPF, making it easy to add to a daily routine. Overall, a solid everyday serum, though the results are gradual rather than instant.
