Summary

This trial will compare how well 3 different topical anesthetics work on patients' pain during treatment for lentigines (age/liver spots) and/or photorejuvenation ( improving skin appearance).

Who is the study for?
This trial is for women aged 25-65 with skin types I-III who have moderate lentigines or photodamage and want laser treatment. They must be in good health, able to consent, and not pregnant. Exclusions include certain medical conditions, recent facial treatments, allergies to anesthetics, chronic pain conditions, liver/kidney disease, or tanned skin.
What is being tested?
The study tests how well different topical anesthetics reduce pain during Q-switched laser treatment for lentigo. It compares lidocaine/prilocaine (LPTA), lidocaine/tetracaine (LTTA), and a placebo. Patients' pain levels are measured after each treated area using a visual scale.
What are the potential side effects?
Possible side effects of the topical anesthetics may include temporary redness, swelling at the application site, itching or tingling sensations. There's also a risk of allergic reactions for those sensitive to lidocaine, tetracaine or prilocaine.
