this retinol trial set is actually really useful, especially for trying out retinol without committing to full sizes. good for when skin starts feeling uneven or a bit tired looking from long weeks or lack of sleep. the night cream works well if skin gets dull from too much sun or stress. the collagen one adds back a bit of bounce, nice after a few nights out or traveling. the cleanser’s great when makeup and sunscreen build up. all three fit in a tiny bag, easy to take for weekend trips or just testing before buying more.
