Aquatherm FAQs

Everything you need to know about caring for sensitive, reactive skin with Aquatherm

Button label
Can I use Aquatherm with other active ingredients like retinol?

Yes, but introduce gradually. Aquatherm strengthens your barrier so you can better tolerate actives. Start with Aquatherm alone for 2-4 weeks, then slowly introduce other treatments. Many clients use Aquatherm in the morning and retinol at night once their skin is stabilized.

Is Aquatherm suitable for acne-prone sensitive skin?

Absolutely. The lightweight, non-comedogenic formulas won't clog pores. Many clients with both acne AND sensitivity find success combining Aquatherm with our Clear Balance range. The barrier-strengthening benefits actually help prevent the sensitivity that can trigger breakouts.

How quickly will I see results?

Most clients report immediate soothing relief from the first application. Visible redness reduction typically occurs within 7-14 days of consistent use, with barrier strength improvements noticeable by week 3-4. Clinical studies show 63% redness reduction in 28 days.

Can I use Aquatherm after cosmetic procedures?

Yes! Aquatherm is clinically tested for post-procedure use and recommended by dermatologists. Consult your practitioner, but most recommend starting Aquatherm 24-48 hours post-treatment. The thermal water and ceramides support healing and prevent irritation.

What makes the thermal water special?

Aquatherm's thermal water comes from a specific geothermal source in Salies-de-Béarn, French Pyrenees. It contains a unique composition of 25+ minerals (including magnesium, calcium, potassium) at specific concentrations clinically proven to calm reactive skin and strengthen barriers. It's not just 'water' — it's pharmaceutical-grade thermal water with documented therapeutic properties.
