FAQS

What does iS Clinical Hydra-Cool Serum do? +

Hydra-Cool Serum provides deep, cooling hydration whilst soothing and calming the skin. It combines hyaluronic acid for intense moisture with centella asiatica for antioxidant protection, vitamin B5 for skin nourishment, and mushroom extract for a brighter, more even complexion. It's designed to comfort irritated, dehydrated, or reactive skin on contact.

Is this the best hydrating serum for sensitive skin? +

Hydra-Cool Serum is an excellent choice for sensitive skin. Its gentle, minimalist formula contains no harsh actives, fragrances, or common irritants. The cooling menthol provides immediate comfort, whilst hyaluronic acid and centella asiatica work together to hydrate and protect without triggering sensitivity. It's trusted by dermatologists and aestheticians worldwide for even the most reactive skin types.

Can I use Hydra-Cool Serum with other iS Clinical products? +

Absolutely. Hydra-Cool Serum layers beautifully with the rest of the iS Clinical range. Apply it after your treatment serums (such as Active Serum or Pro-Heal Serum Advance+) to add hydration and help buffer any potential irritation from active ingredients. It can also be used on its own as a standalone hydrator for days when your skin needs something simple and soothing.

Does iS Clinical Hydra-Cool Serum help with redness and rosacea? +

Yes. The cooling, soothing formula is particularly beneficial for redness-prone and rosacea skin. Centella asiatica provides powerful antioxidant support, whilst the menthol cools and calms visible irritation. Many users with rosacea report noticeable comfort and reduced redness with regular use. However, if you have a diagnosed skin condition, it's always worth consulting your dermatologist.

Can I use Hydra-Cool Serum on sunburnt skin? +

Hydra-Cool Serum is excellent for soothing sunburnt skin. The menthol delivers an immediate cooling sensation that provides comfort, whilst hyaluronic acid helps replenish lost moisture. It's also a great option for calming skin after laser treatments, chemical peels, or microneedling. Apply generously and reapply as needed for relief.

Is Hydra-Cool Serum suitable for oily or acne-prone skin? +

Yes. The lightweight, oil-free gel texture absorbs quickly without leaving any greasy residue, making it ideal for oily and blemish-prone skin types. It provides essential hydration without clogging pores or contributing to excess oil production. On oilier skin types, it can be used alone without a moisturiser on top.

When should I apply Hydra-Cool Serum in my skincare routine? +

Apply Hydra-Cool Serum after cleansing and toning, and after any treatment serums (such as vitamin C or retinol). Follow with your moisturiser if needed, and always finish with SPF in the morning. It can be used both morning and evening as part of your daily routine.

Is Hydra-Cool Serum good for travel? +

Hydra-Cool Serum is a travel essential. Air-conditioned cabins and dry hotel rooms can leave skin feeling dehydrated and uncomfortable. This serum works to replenish moisture lost during air travel and helps keep skin calm and hydrated in changing climates. The 15ml travel size is also available for on-the-go convenience.

Is iS Clinical Hydra-Cool Serum safe during pregnancy and breastfeeding? +

Yes. Hydra-Cool Serum is considered safe for use during pregnancy and breastfeeding. It contains no retinoids, high-dose salicylic acid, or other ingredients commonly advised against during pregnancy. The formula uses gentle, skin-friendly ingredients including hyaluronic acid, centella asiatica, and vitamin B5. As with any skincare product, consult your GP or midwife if you have specific concerns.
