i bought this in taiwan, so the price was a bit heftier than i would have paid in hong kong (but i haven't seen this product here as of yet!), but it's still cheap like many BP products. it's bigger than the milky base and i got this in light beige. it seems to have the bonus of more colour correction than the milky base because of it's tint. it evens out skin tone, but i think the milky base holds makeup better during the day! it also has this very plasticy smell which i don't really like, but it's nothing major. not sure whether i would buy this again, because i think for me, the milky base is a better product.
Haidaro base is similar to Milky/Jelly Base but it's tinted in 2 shades - light Beige? and Natural Beige. This can be use as primer base or tinted moisturiser. I use this base on top of my sunscreen and this base makes my skin smoother, moisturises and evens out my skintone.
