This serum contain 0.2% retinol, which is one of the most effective ingredient for anti-wrinkles. I really cannot find any retinol product at lower price.
However, 0.2% is a little bit high and irritating. Some people may need a week or two to accustom to it.
I don't know why they are not very popular in countdown. Does anybody have better serum choice?
This is available at The Warehouse for $46 so you could try a pricebeat and get another 10% off Countdown's price (making it $29.70). May be hard as they are doing a buy one get one half price offer.
However, if the pricebeat fails and you use it a lot you could buy two for $69 with the offer and then get another $5 off $50 in the App.
Makes it $64 for two.
