    Advantages: 1. Effective concentration of niacinamide - I've heard that niacinamide, a multi-beneficial ingredient for the skin, needs to be present at a concentration of at least 10% to be effective. This product focuses specifically on delivering a high concentration of niacinamide, making it an excellent choice for beginners. 2. Minimal irritation - Despite being a high-concentration product, which might lead one to expect skin irritation, this formula seems to be quite gentle. It has a water-like texture that leaves a slight coating feeling on the skin, but not to an uncomfortable degree.
    Disadvantages: 1. Volume - Given its high concentration of active ingredients, the product is quite expensive for its volume. I suppose that's unavoidable with such formulations. 2. Not suitable for use on broken skin - I wouldn't recommend using this if you've popped a pimple or have any open wounds on your skin. It can cause a tingling sensation.
    I recommend applying this high-concentration product immediately after toner for quicker absorption.

    While it feels a bit heavy for summer, the price is great and it absorbs well with decent application. I'd recommend it for acne-prone skin with enlarged pores.
    It's a bit heavy for summer, but still good value for money.
