Kojic acid mistakes to avoid

Most kojic acid disappointments trace back to a few avoidable mistakes. These are the ones to check first.

The most common mistakes

Mistake number one is believing that stronger is always better. In reality low percentages combined with SPF are less irritating and effective.

Normal sensation: may sting in reactive skin. Lasting sting, flaking or redness is not normal. Patch test if sensitive.

Pause kojic acid for a week. Use only cleanser, moisturizer and SPF, then restart at half the frequency.

Expect eight to twelve weeks once the routine is stable.

The same ingredient behaves differently on different skin, so adapt the schedule rather than the product.

Here is how kojic acid could slot into a simple day, given that it is best used evening.

Write down one line per week. Skin changes slowly, and notes beat memory.

Starting too fast. Every other night is a safer opening.

Pause, hydrate and reintroduce slowly.

Mild tingling that fades quickly is common; lasting sting means reduce frequency.

Not quite: low percentages combined with SPF are less irritating and effective.
