One of the most common mistakes clients make after an aesthetic treatment is underestimating the sun. Whether you have just had a chemical peel, a Dermapen microneedling session or a carboxytherapy treatment, your skin enters a heightened state of sensitivity — and UV exposure during this window can permanently compromise your results.
Why Treated Skin Burns Faster
Aesthetic treatments work by triggering controlled changes in the skin — removing surface layers, stimulating collagen, or disrupting pigment. During healing, the skin's protective melanin barrier is temporarily compromised, meaning UV rays penetrate deeper and cause more damage than they would on untreated skin. Even ten minutes of unprotected sun exposure can cause hyperpigmentation that takes months to fade.
SPF 50 Is the Minimum, Not the Maximum
We recommend SPF 50+ broad-spectrum sunscreen for at least four weeks after any resurfacing treatment, reapplied every two hours when outdoors. Choose a mineral formula (zinc oxide or titanium dioxide) rather than chemical filters — mineral SPF sits on top of the skin and reflects UV rather than absorbing it, which is gentler on a compromised barrier.
The Estonia Factor
Clients often assume that Baltic weather means lower UV risk. This is a myth. UVA rays — responsible for pigmentation and ageing — penetrate cloud cover and glass year-round. In Tallinn, we see clients experiencing post-inflammatory hyperpigmentation in February just as often as in July. Sunscreen is a twelve-month commitment after treatment, not a summer one.
Practical Tips From Our Team
Apply SPF as the very last step of your morning routine, after moisturiser. Wear a wide-brimmed hat if you will be outdoors for more than fifteen minutes. Avoid saunas, steam rooms and intense heat for the first week after treatment. And if you must be in the sun, seek shade between 10am and 4pm when the UV index peaks.
