Perfect match! I've been wanting to try @shiseidoid #Ultimune but I'm unsure whether it would suit me or not. So I decided to get a sample size from @skiicorner before committing to a full bottle purchase.First of all, you need alot of this product for your whole face so 10ml can probably only lasts for 3 weeks if you're lucky. So a full bottle of 30ml can only lasts for 1,5 months. It's a good product that provide what you want from a booster. Although the texture is a thin lotion cream, but it absorbs real quick. Hence, you need to be real generous in application.I'm certainly considering buying full size.
