It’s true—skin treatments can give you healthier, more radiant, and glowing skin. But without the right aftercare, you might not get the full benefits.
One of the easiest and most important aftercare steps is applying sunscreen. This article explains why sunscreen is still a must after treatments like Botox, fillers, or skin boosters, and how to pick one that works best for your post-treatment skin.
Why do you need sunscreen after skin treatments?
After treatments like Botox, fillers, or skin tightening devices, your skin may feel irritated, tender, or slightly sensitive. During this time, sunlight and UV rays are your skin’s worst enemy. They can trigger inflammation, dullness, or slow down healing—ultimately weakening the results of your treatment, especially those that boost collagen.
That’s why sunscreen is a simple yet powerful way to protect your skin at a cellular level and maintain your results longer.
Which treatments require special attention to sunscreen use?
Botox and fillers
Although these don’t directly affect the skin surface, UV rays can still damage the collagen underneath, making it easier for new wrinkles to form. Sunscreen acts as a protective barrier that helps slow down aging and maintain skin smoothness.
MADE Collagen, AuraWhite, and skin booster treatments
After injecting vitamins or skin nutrients, external protection is just as important as internal repair. Sunlight can damage newly revived collagen, so sunscreen helps preserve that glow and moisture for longer.
Energy-based lifting devices
These treatments aim to stimulate collagen and tighten the skin. Some people may feel minor skin soreness afterward. Skipping sunscreen could expose your recovering skin to UV damage, possibly causing new wrinkles.
How to apply sunscreen properly after treatments
Wait 3 hours for needle marks to close
Avoid applying skincare or cosmetics right after a procedure. Let the needle marks or swelling subside before putting on sunscreen.
Choose gentle formulas – Fragrance-free and alcohol-free
Go for mild, non-irritating sunscreens suitable for sensitive, post-treatment skin. Look for lightweight textures that spread easily and won’t clog your pores—like formulas designed for sensitive skin.
Use sunscreen with SPF50 PA+++ or higher
High-SPF sunscreen provides better protection against both UVA and UVB rays, which cause wrinkles, dark spots, and pigmentation.
Apply daily – Rain or shine, indoors or outdoors
Even if it’s cloudy or you stay indoors, UV rays are still present. Apply sunscreen every morning using enough product—about two finger lengths, as commonly recommended.
Reapply every 2–3 hours in the sun or when sweating
Especially on days when you're outside, reapplying ensures consistent protection throughout the day.

What happens if you skip sunscreen?
- You may experience sunburn, redness, or peeling after long sun exposure.
- Your skin tone could become uneven, with dark spots, freckles, or dullness.
- Treatment results won’t last as long compared to those who use sunscreen regularly.
- You could waste money on treatments but not get the full effect due to poor aftercare.
Post-treatment skincare starts with sun protection
As you can see, taking care of your skin after a treatment starts with something simple—using a high-SPF, gentle sunscreen every day in the right amount. This helps your skin heal, reduces side effects, and protects it from one of the biggest threats in Thailand: the sun.
