I only stay indoors. Do I really need sunscreen after treatment?
This is a question often asked by people who say they are hardly ever outdoors apart from commuting. It can feel like a hassle, and you may worry about the burden on your skin.
After treatment, ultraviolet exposure can affect pigment changes, so it is good to review how you manage it even if you live indoors.
You are exposed even indoors
Ordinary window glass lets some ultraviolet light (UVA, etc.) through. If you work by a window or spend long hours driving, the exposure is not small.
On top of that, after a treatment that applies heat or irritation (depending on the type of treatment), the skin may become more sensitive to pigment changes than usual.
How should I apply it?
It depends on the type of treatment, but starting the day after treatment with a gentle product is common. If the amount is too small, the level of protection may be lower, so it is good to apply a sufficient amount evenly. If you are out for a long time, reapplying as advised is generally recommended.
If choosing a product is hard, start with one that has simple ingredients and no fragrance. The timing of use can differ depending on the condition of the treated area, so please also check the guidance from the clinic where you were treated.
Frequently asked questions
Q. Can I apply it from the day of treatment?
A. It depends on the type of treatment. If the skin barrier is damaged, starting from the next day is often recommended.
Q. When I reapply sunscreen, do I have to remove the old layer first?
A. If you are going out repeatedly, you can reapply over it. In the evening, it is good to cleanse thoroughly in a gentle way.
Q. What if sunscreen causes breakouts?
A. Try switching products, and if it keeps happening, the ingredients need to be checked. If stinging, redness, or itching after applying persists or gets worse, stop using it and contact the clinic. Finding a product that suits you is better than stopping protection altogether.
