Axis-Y Dark Spot Correcting Glow Serum
A niacinamide serum with squalane and fruit extracts, and the product that carried a small brand into international rotation. Niacinamide is the working ingredient and one of the few with a decent evidence base for the appearance of uneven tone, texture and pore visibility; squalane keeps the finish comfortable rather than dry. The texture is a light lotion that leaves a soft sheen, which is where the glow in the name comes from.
What it is built around
Who it suits
Combination, oily and normal skin working on the look of post-blemish marks and general unevenness, and dry skin that finds most tone serums stripping. It is a reasonable everyday step rather than a corrective one. People who flush from niacinamide should be careful, and anyone with a bee-product allergy should check the current formula, as the brand has used honey-derived ingredients across its range.
How to use it
After toner, before moisturiser, morning or evening — once daily is enough to start. Two or three drops over the whole face. Morning use goes under sunscreen. Judge it over a couple of months; niacinamide is a slow ingredient and no serum in this category changes anything in a fortnight.

What is the difference between essence and serum?
In Korean skincare, essence is typically a thinner, hydration-focused layer that preps skin, while serum is more concentrated with targeted actives like vitamin C or niacinamide. Essence usually comes first; serum follows. The line between them blurs, and not every routine needs both.
What is the difference between essence, serum and ampoule?
Essence is the lightest and most hydration-focused, serum is more concentrated and targeted, and ampoule is the most concentrated of the three. The boundaries are marketing convention, not regulated definitions.
