Lactic acid mistakes to avoid

Most lactic 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 it is too gentle to matter. In reality its larger molecule penetrates slowly, which is why it suits beginners.

Normal sensation: mild and hydrating. Lasting sting, flaking or redness is not normal. Start 1–2 nights weekly.

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

Expect three to four 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 lactic 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. One to two nights weekly is a safer opening.

Pause, hydrate and reintroduce slowly.

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

Not quite: its larger molecule penetrates slowly, which is why it suits beginners.
