Impact of AHA on Laser Mole Removal and Acne Treatment Duration

Laser mole removal and issues related to retinoic acid?

Hello, doctor.
I had laser mole removal, but there are some pimples around the wound.
I am currently using a third-generation topical retinoid, but I accidentally applied it to the laser wound.
What impact could this have on the wound? Also, how long does it usually take for topical retinoids to completely treat acne? Thank you, doctor.

Applying A acid to wounds primarily causes irritation, and doing so once or twice should not pose significant issues.
As for how long it takes to treat acne, there is no definitive answer.
The treatment of acne is more about management rather than complete eradication, as there are numerous factors influencing acne, many of which are related to lifestyle, dietary habits, and individual constitution.
It is important to evaluate the underlying causes of your acne and focus on controlling those factors.

When considering the impact of topical retinoids, such as third-generation retinoids (like adapalene), on laser mole removal and the treatment of acne, it is essential to understand both the healing process of the skin and the nature of these medications.

First, regarding the application of topical retinoids on the area surrounding a laser mole removal site, caution is advised. Retinoids work by promoting cell turnover and can cause skin irritation, dryness, and increased sensitivity. Applying a retinoid to a fresh laser treatment site may exacerbate irritation and delay healing. The laser procedure creates a controlled injury to the skin, and the surrounding area is already in a sensitive state. Therefore, it is generally recommended to avoid applying any active ingredients, including retinoids, directly on the treated area until it has fully healed. This healing period can vary depending on the depth of the laser treatment but typically ranges from a few days to a couple of weeks. It is crucial to follow your dermatologist's post-procedure care instructions to ensure optimal healing and minimize complications.

As for the duration of acne treatment with topical retinoids, the timeline can vary significantly based on several factors, including the severity of the acne, the specific retinoid used, and individual skin response. Generally, patients may begin to see improvements within 4 to 12 weeks of consistent use. However, complete resolution of acne may take several months, and it is essential to maintain a regular application schedule. Most dermatologists recommend using topical retinoids nightly, starting with a pea-sized amount to minimize irritation. If irritation occurs, it may be beneficial to reduce the frequency of application or consult with your dermatologist for personalized advice.

In summary, while topical retinoids are effective for treating acne, they should be used cautiously around areas that have undergone laser treatment. Avoid applying them directly to the treated area until it has healed completely. For acne treatment, patience is key, as it may take several weeks to months to achieve the desired results. Always consult with your dermatologist for tailored advice and to ensure that your treatment plan is safe and effective.
