iS Clinical Youth Body Serum Review

iS Clinical Youth Body Serum is a lightweight, fast-absorbing hydrating mist for the body, built around 0.9% Sodium Hyaluronate, the brand's Extremozymes® enzyme technology, and an antioxidant botanical blend including watermelon and blue micro algae. It comes as an aerosol spray across three sizes, suits most skin types per iS Clinical, and is lightly fragranced with Brazilian blood orange — so it isn't a fragrance-free formula.

What it is

Youth Body Serum sits in iS Clinical's Youth line, alongside facial products like Youth Serum, but this one is formulated and packaged specifically for the body — arms, chest, hands and décolletage. Rather than a traditional cream or lotion, it's dispensed as a fine aerosol mist, which iS Clinical says covers the full body in around ten pumps. It's positioned as a treatment-style hydration step rather than a heavy moisturiser, and the brand suggests it can be layered under a body cream such as Body Complex for extra richness in colder months, or used alone.

Quick facts

Key ingredients

The formula is built on Sodium Hyaluronate at 0.9%, a humectant iS Clinical says binds significant amounts of water to help hold moisture in the skin. Sitting alongside it is Imperata Cylindrica Root Extract, included by the brand to support the skin's moisture-absorption process, and Panthenol (pro-vitamin B5), a well-established humectant and barrier-support ingredient used to help improve the appearance of dryness.

The antioxidant side of the formula draws on Watermelon Fruit Extract, Blue Micro Algae (Phormidium Persicinum Extract) and Ergothioneine, included to help defend the skin against everyday environmental exposure. Aloe Barbadensis Leaf Juice and Dipotassium Glycyrrhizate (a licorice root derivative) are included for their soothing properties, which is why iS Clinical positions the mist as suitable for use after sun exposure.

iS Clinical's own copy also names its proprietary Extremozymes® technology and describes DNA-protective benefits from it; we've kept that as the brand's stated aim rather than an independently verified claim, since no supporting study data was supplied for this specific SKU. Worth noting too: the full ingredient list includes Butyl Methoxydibenzoylmethane and Ethylhexyl Salicylate, both UV-filtering compounds — present in the formula, but this isn't marketed or tested as an SPF product, so it shouldn't be relied on in place of a dedicated sunscreen.

Who it suits — and who should skip it

• Anyone wanting a fast, non-greasy way to hydrate large areas of body skin without a cream's weight or wait time
• Dehydrated or sensitive skin, per iS Clinical's own suitability claim
• Post-shower or post-sun use, where a cooling mist is more comfortable than rubbing in a lotion
• Anyone who wants to layer light hydration under a richer body cream rather than replace one

Think twice if you're avoiding fragrance — the blood orange note means this isn't fragrance-free — or if you're looking for a standalone SPF; it isn't formulated as sun protection despite containing UV-filtering ingredients.

How to use it

Hold the bottle roughly six to eight inches from the skin and spray evenly over the area, using your hands to smooth it in if you prefer. iS Clinical suggests around ten pumps for full-body coverage. It's designed to be used as often as needed through the day without buildup, and works particularly well applied to slightly damp skin straight after showering, to help seal in moisture. It can be used alone for a lightweight finish, or layered under a body cream or SPF for more coverage.

Our verdict

Youth Body Serum is a genuinely different proposition to a standard body lotion: a lightweight, fast-absorbing mist that gets Sodium Hyaluronate and an antioxidant botanical blend onto large areas of skin in seconds, without the heaviness or wait time of a cream. It won't suit anyone avoiding fragrance, and it isn't a substitute for SPF, but as a layerable hydration step — especially post-shower or post-sun — it earns its place. iS Clinical prices it within its premium treatment-serum tier, in line with the rest of the range rather than a standard drugstore body product; see the current price on the product page.

FAQs

What's the difference between Youth Body Serum and Body Complex?

They're complementary rather than interchangeable. Body Complex is a treatment-style lotion built around Retinyl Palmitate and gentle fruit-acid exfoliation for dry, rough or compromised skin. Youth Body Serum is a lighter mist focused on hydration and antioxidant protection, without any exfoliating or retinoid component — iS Clinical suggests pairing the two, using the serum first and Body Complex to seal it in.

Can I use Youth Body Serum on my face?

iS Clinical markets it primarily as a body product, though the formula is fragranced, which is worth factoring in if you're considering it for facial use. For the face, the brand's dedicated Youth Serum is the purpose-built option.
