Lactic Acid

Q. How to use Lactic Acid?

Before using Lactic Acid, clean and dry the affected area. Gently and thoroughly massage it into the skin. Be careful not to get the medication in your eyes or mouth. If Lactic Acid gets in your eyes accidentally, wash with plenty of water and call your doctor if your eyes are irritated.

Q. What should prompt me to discontinue Lactic Acid?

You should discontinue Lactic Acid and consult your doctor if you experience severe local irritation, which means severe redness, dryness and itching and stinging/burning sensation.

Q. What precautions should be followed while applying Lactic Acid?

Use Lactic Acid only on your skin. Keep it away from areas like your eyes, eyelids, lips, mouth and inside of the nose. If the medicine comes in contact with any of these areas, wash the affected area with water immediately. Avoid using Lactic Acid on scratched or eroded skin and open wounds. Take care when using Lactic Acid on sensitive areas of skin such as your neck. Lactic Acid can make your skin more sensitive to the harmful effects of the sunlight. So, avoid the use of sunbeds/lamps and minimize the time you spend in the sun. You should use sunscreen and wear protective clothing while using Lactic Acid. Avoid contact with hair as Lactic Acid has bleaching properties. It can even bleach dyed or colored fabric, furniture or carpeting.

Q. How often should I apply Lactic Acid?

The initial dose is preferably once daily in the evening. Later, the doctor will gradually increase the dose to twice daily (most probably morning and evening).

Q. How long does Lactic Acid take to show its effects?

You may see an improvement after 4-6 weeks of treatment. You may need to use this treatment for longer to see the full benefits. This is normal for such skin treatments. If your condition does not get better after 1 month or if it gets worse, talk to your doctor immediately.

Q. Do you apply moisturizer before or after Lactic Acid?

You may apply moisturizer an hour after applying Lactic Acid. Consult your doctor in case of any doubt or concern.
