Sun protection after aesthetic treatments — Complete guide

The single most important aftercare factor for almost all aesthetic procedures is sun protection. Inadequate protection can ruin the result, cause pigmentation spots or, in the worst case, scarring.

Why is sun protection critical after treatment?

After aesthetic treatments the skin is in a healing phase. New skin cells and a rebuilt barrier are extra sensitive to UV:

• UVB → burns new skin → scars
• UVA → activates melanocytes → pigmentation spots
• Both → breakdown of newly formed collagen

Protocol per treatment

Botox

• 24h no direct sun
• SPF50 daily (for general reasons)

Fillers

• 48h no direct sun
• 1 week no intense sun exposure
• SPF50 daily

Laser (IPL / fractional)

• 4–6 weeks no direct sun
• SPF50 in a thick layer, reapplied every two hours outdoors
• A wide-brimmed hat is recommended

Chemical peel

• 2–4 weeks no direct sun
• SPF50 whenever you are outdoors
• Avoid sun holidays for 4 weeks

Microneedling

• 1 week no direct sun
• SPF50 from day 2
• Avoid pools/the sea for 48h

Which sunscreen?

• SPF level: At least 50
• Broad spectrum: UVA + UVB (often labelled "PA++++" or "broad spectrum")
• Mineral or chemical: Mineral (zinc oxide, titanium dioxide) is gentler after invasive treatments
• Amount: Two finger-lengths for the face — almost everyone applies too little

Reapplication

• Every two hours during sun exposure
• After bathing, swimming or heavy sweating
• Powder or spray form for make-up-free reapplication

Indoors too?

Yes, when working by a window. Glass blocks UVB but lets UVA through — which causes pigmentation and photoageing. SPF daily, even in winter.

Myths

• ❌ "SPF30 is enough" — after treatment: no
• ❌ "Cloudy = no risk" — 80% of UV passes through clouds
• ❌ "Dark skin needs less" — the risk of pigmentation is just as high or higher
• ❌ "SPF is carcinogenic" — no studies support this
