iS CLINICAL Hydra-Cool Serum is a lightweight, antioxidant-rich face serum that refreshes, soothes, and delivers visible hydration without a heavy finish.

The formula is crafted for daily use under moisturizer and makeup, offering targeted comfort when skin feels reactive, dehydrated, or stressed.

How does the Hydra-Cool Serum relieve redness and sensitivity?

The serum combines antioxidant protection with calming botanicals to help skin look less reactive after environmental or daily stresses. Its soothing ingredients work with the serum's cooling texture to immediately comfort the skin while supporting a more even-looking tone over time.

• Lightweight delivery encourages quick absorption without residue.

What hydration benefits can I expect from this 0.5 fl oz serum?

Hydra-Cool Serum is formulated to bind and retain moisture, improving skin plumpness and softness without adding oily weight. Regular use helps maintain comfortable hydration between heavier creams or as a standalone lightweight boost on warmer days.

• Targets moisture retention to smooth texture and reduce dryness.
• Works beneath moisturizers and sunscreens without pilling.
• Suitable for layering in morning and evening routines.

How should I incorporate this serum into my skincare routine?

Apply the Hydra-Cool Serum after cleansing and toning, before heavier creams or oils. A small amount is enough to cover the face and neck; gently press into skin until absorbed. It pairs well with antioxidant serums or broad-spectrum SPF for daytime protection.

• Use morning and night for best hydration and calming effects.
• Apply 2–3 drops to damp skin to boost absorption and comfort.
• Layer under moisturizer and sunscreen for daytime protection.

Will this serum feel heavy or leave a residue?

No—the serum has a lightweight, cooling finish designed to absorb cleanly. It delivers comfort and hydration without tackiness, making it suitable for combination and oilier skin types that still need soothing hydration.

• Fast-absorbing texture avoids greasy or sticky film.
• Leaves skin feeling refreshed, not weighed down.
