Perfect HA

This is the perfect HA serum. Absorbs in the skin nicely while being hydrating. Does not make products I put on top of pill either.

Calms my skin faster than I calm myself

This serum is basically a chill pill for angry skin. Red, irritated, over-exfoliated, or just dramatic? Two pumps of Hydra-Cool and my face immediately stops filing formal complaints. It’s lightweight, sinks in fast, and doesn’t leave me shiny, sticky, or questioning my life choices. It layers beautifully under moisturizer, SPF, and actives — no pilling, no beef with retinol, no chaos. I especially love it post-treatment or on mornings when my skin wakes up choosing violence. That said… for the price, I did briefly expect it to pay my bills. The hydration is excellent but not long-lasting on its own, so you will still need a moisturizer unless you live in a rainforest or have naturally unproblematic skin (couldn’t be me). Why four stars? Because it’s amazing at calming and cooling, but it’s a supporting character, not the main hydration star. Incredible vibes, just not a one-product routine. Best for: sensitive or reactive skin, redness, post-procedure care, and people who like their skincare effective but not dramatic. Would I repurchase? Yes — while side-eyeing the price the entire time.

Really Like

I got the sample size first and like it so much I purchased the full size. It hydrates my skin without making it feel greasy. I have sensitive, acne prone skin. This product works well for my difficult skin.

Soothing

I love this product, I use it twice a day and see the results dramatically when I use this product consistently. I can also see immediately when I don’t use the product. This leaves my skin feeling soothed and smoothed.

The best

Hands down the best hydrating serum on the market. Cooling, lays well under makeup and other serums, perfect for my type 2 rosacea.

Refreshing, gentle, hydrating serum

This serum glides on my skin and feels super refreshing. I use it before a night moisturizer when my skin is feeling extra dry and in the morning layered over the pro heal serum. It feels very smooth on my sensitive skin and doesn’t cause any irritation.

Absorbs quickly

Nice serum that absorbs quickly and doesn’t leave your skin feeling oily or dry, just smooth and plumped when used with the is clinical reparative moisture emulsion.

Dehyrate

The Hydra-Cool serum feels so good on my face. It definitely helps with my dry skin. I’ve become addicted to this stuff!

Just OK

I purchased this thinking it will really hydrate my skin. I don’t feel like it hydrates as much as I expected. Perhaps it is because the menthol in it? I have been using it for about 3 weeks now. I don’t think I will repurchase this.

Wonderful

This is a great product. I had been searching for a serum that wouldn't make me breakout or cause redness. My skin is super sensitive. This is the one. My skin has smoothed, evened and glows. People who have not seen me for a while , commented on how youthful I look, and me with gray hair. They tell me I look 40/45. I am 67! Thank you iS clinical!

Hmmm

This felt nice and cooling initially but I’m not sure if it actually helped hydrate my skin more. Probably won’t repurchase but it was nice to use!

Soothing

Recommended by my aesthetician, IS CLINICAL Hydra-Cool Serum is just that. I use it in the evening to prep my skin for retinoid application. My skin used to feel dry and tight as a result, but now it feels smooth and silky.
