iS Clinical Hydra Intensive Cooling Masque Review
The Verdict
Hydra Intensive Cooling Masque is a well-built hydrating gel mask for anyone whose skin needs a calm, cooling moisture hit rather than an active treatment — dehydrated, sensitised, or sun-stressed skin is exactly what it's aimed at. It sits at the professional end of the price spectrum, which is worth knowing going in, but the formula itself is straightforward and low-risk: humectants and calming botanicals rather than exfoliants or actives. It's not a substitute for SPF, a barrier balm, or your practitioner's specific aftercare advice, but as an occasional or nightly hydrating step it does the job well.

How to use it
Apply a generous layer to cleansed skin, avoiding the eye area. Leave on for around 10 minutes as a quick treatment, then remove with a damp cloth or rinse off — or, for more intensive hydration, leave it on overnight and let it absorb fully rather than rinsing. It layers well before a serum and moisturiser the following morning, and can be used a few times a week depending on how your skin responds.
Key ingredients
The formula is built around botanically-derived hyaluronic acid, a humectant capable of holding many times its own weight in water at the skin's surface, which is what gives the masque its intensive, plumping hydration. Alongside it sits a Centella Asiatica complex — derivatives including asiaticoside, asiatic acid and madecassic acid — long used in skincare to help calm and soothe stressed-looking, reactive skin, which is why this masque is positioned for sensitive and post-sun use.
The rest of the formula leans on antioxidant-rich botanicals: green tea, resveratrol, grape seed extract, aloe vera and rosemary. These are included to help protect skin from everyday environmental stressors and to support the calming, refreshing feel of the mask, rather than to deliver a targeted treatment effect on pigmentation, lines or breakouts.
Because the formula is hydration- and calming-led rather than exfoliating or actives-led, it's a genuinely low-risk product to introduce, even into routines that already include stronger treatment serums elsewhere in the week.
What it won't do
This is a hydrating and soothing mask, not a treatment product — it isn't formulated to exfoliate, target pigmentation, or replace a dedicated vitamin C or retinoid serum in your routine. If your main concern is texture, tone or fine lines specifically, this masque supports the skin around those treatments rather than doing that job itself.
Pregnancy and breastfeeding
If you're pregnant or breastfeeding, please contact our team for advice before use.
Where it fits in an iS Clinical routine
For a lighter, everyday hydrating layer with a similar cooling effect, the Hydra-Cool Serum is a natural companion — use the serum daily and this masque as a weekly or as-needed intensive top-up. For very dry, compromised or barrier-stressed skin, pairing it with the richer Sheald Recovery Balm gives you both an intensive hydrating step and an occlusive barrier layer. You can browse the full iS Clinical range on Skintique Academy, or see the product itself on the Skintique product page.
