Post-treatment care for laser therapy of flat warts?


Hello, I have extremely oily skin and a lot of acne.
About a month ago, I underwent laser treatment for flat warts, so I would like to ask:
1.
How can I apply sunscreen without clogging my pores and causing more acne? It seems that sunscreens with higher SPF are oilier.
Currently, my method is to use an SPF 15 sunscreen in the morning before leaving at 8 AM, and then wash my face with just water at noon.
After drying my face, I apply SPF 15 sunscreen again.
The clinic staff mentioned that washing my face with just water is sufficient, but I feel like it might not be clean enough, and on weekends when I go out, I can't wash my face.
2.
How long should I wait before using skincare products that contain L-ascorbic acid or other ingredients that may contain alpha hydroxy acids?
3.
Since flat warts can self-infect, should I wash my face towel after each use? Should I change my pillowcase daily? How often should I replace my powder puff and makeup sponges?
4.
What foods can cause hyperpigmentation, flat warts, and acne? Which foods can help prevent them?
5.
Do sunscreens marketed as "non-comedogenic" really work? If a tinted moisturizer does not have SPF, can it still provide sun protection?
Thank you for your answers; I greatly appreciate it.

1.
When selecting sunscreen products, foundations, lotions, etc., it is best to choose those labeled as non-comedogenic, non-acnegenic, or won’t clog pores, indicating a lower likelihood of causing acne.
If you feel your face isn't clean, you can use your usual facial soap.
If you can't wash your face while out on weekends, you can use oil-absorbing sheets to dab your face and then reapply sunscreen.

2.
Using L-ascorbic acid (Vitamin C) is fine.
Since your laser treatment was done a month ago, the wound should have healed.
If the alpha hydroxy acid is not too irritating, it is also acceptable.
However, do not use scrubs or exfoliating cleansers that contain granules.
3.
If your flat warts have healed, replace old sponges and makeup applicators, and wash and dry your towels and pillowcases.
If you still have flat warts, just maintain your usual habits and be a bit more diligent.
Do not share personal items with others.
4.
The impact of food is minimal.
5.
The term "non-comedogenic formula" means it is designed not to cause acne; it does not treat or reduce existing acne but prevents the formation of new acne or worsening of existing conditions.
Products without a sun protection factor (SPF) label typically have lower sun protection capabilities, often less than SPF 15.

Managing oily skin, especially after undergoing laser treatment for flat warts, requires a careful approach to skincare. Here are some tips and insights regarding your questions:
1. Sunscreen Application: It's crucial to protect your skin from UV rays, especially after laser treatment, as your skin will be more sensitive. Look for non-comedogenic sunscreens that are specifically formulated for oily or acne-prone skin. These products are designed to provide sun protection without clogging pores. A broad-spectrum sunscreen with an SPF of at least 30 is recommended. If you find that higher SPF products feel too greasy, consider using a gel-based or matte-finish sunscreen. You can also try mineral sunscreens containing zinc oxide or titanium dioxide, which tend to be less irritating and can absorb excess oil. When reapplying, consider using a powder sunscreen or a setting spray with SPF to avoid the need for washing your face multiple times a day.

2. Using Active Ingredients: After laser treatment, your skin may be more sensitive, so it's essential to wait before introducing potent active ingredients like L-ascorbic acid (Vitamin C) or alpha hydroxy acids (AHAs). Typically, it's advisable to wait at least 1-2 weeks post-treatment before reintroducing these products. Always start with a patch test to ensure your skin can tolerate them. If your skin shows no adverse reactions, you can gradually incorporate them into your routine.

3. Hygiene Practices: To prevent re-infection of flat warts, maintaining good hygiene is vital. Wash your face towels after each use, and consider using disposable options if possible. Change your pillowcases at least once a week, and if you experience any breakouts or irritation, consider changing them more frequently. For makeup tools like sponges and powder puffs, it's best to wash them weekly to minimize bacteria buildup. If you notice any signs of irritation or infection, replace these tools immediately.

4. Diet and Skin Health: Certain foods can exacerbate oily skin and contribute to acne. High-glycemic foods (like white bread and sugary snacks) can lead to increased oil production and breakouts. Dairy products have also been linked to acne in some individuals. Instead, focus on a balanced diet rich in fruits, vegetables, whole grains, and lean proteins. Foods high in antioxidants, such as berries, nuts, and green leafy vegetables, can help combat inflammation and promote skin health. Staying hydrated is also essential for maintaining skin moisture balance.

5. Non-Comedogenic Sunscreens: Many sunscreens are marketed as "non-comedogenic," which means they are formulated to not clog pores. However, the effectiveness can vary by individual. It's essential to read labels and look for products that specify they are suitable for oily or acne-prone skin. If a tinted moisturizer or primer does not have SPF, it will not provide adequate sun protection. Always layer a dedicated sunscreen underneath any makeup products for proper UV protection.

In conclusion, managing oily skin post-laser treatment involves a combination of proper sun protection, careful introduction of active ingredients, maintaining hygiene, and being mindful of your diet. Always consult with your dermatologist for personalized recommendations tailored to your specific skin type and treatment history. Regular follow-ups can help monitor your skin's response and adjust your skincare routine as needed.
