iS Clinical Liprotect SPF 35 Review

iS Clinical Liprotect SPF 35 is a mineral, broad-spectrum SPF treatment made specifically for the lips, combining zinc oxide and titanium dioxide with vitamin E, coconut oil and elderberry extract. It's designed to sit clear and non-sticky on the lips, with a light cherry flavour, making it suitable for daily wear alone or underneath lip colour.

What it is

Lips have thinner skin than the rest of the face and produce little of their own oil, which leaves them more exposed to UV damage and dryness. Liprotect SPF 35 addresses this with an all-physical (mineral) sunscreen base of zinc oxide and titanium dioxide, providing broad-spectrum UVA/UVB protection at SPF 35. Botanical and vitamin actives are included to condition and support the lip barrier alongside the sun protection.

Key ingredients

• Zinc oxide & titanium dioxide — physical (mineral) UV filters that sit on the skin's surface to reflect UVA and UVB rays, delivering the product's SPF 35 rating.
• Vitamin E — an antioxidant included to help condition the lips and support the skin barrier.
• Coconut oil — an emollient that helps hydrate and soften dry or chapped lips.
• Elderberry extract — a botanical antioxidant included as part of the formula's environmental-defence profile.

Because the SPF actives are mineral rather than chemical, the formula sits as a transparent film rather than absorbing into the skin, which is why the brand describes it as leaving no white cast.

Texture, finish and flavour

The formula has a smooth, balm-like texture that glides on without feeling heavy or greasy, and it's designed to leave a non-glossy, transparent finish so it can be worn on its own or layered underneath lipstick or gloss. It carries a light cherry flavour and scent as part of the formulation — worth knowing in advance if you're sensitive to flavoured lip products or generally prefer fragrance-free/unflavoured balms, as this one is not fragrance-free.

Who it's for

• Anyone whose lip care routine currently skips SPF
• Those who spend time outdoors, commuting, or are otherwise exposed to daily UV
• People who prefer mineral (physical) sunscreen formulations over chemical filters
• Anyone dealing with dry, chapped or environmentally-stressed lips who wants conditioning as well as protection

If you find cherry-flavoured or scented lip balms irritating, or you're looking for a completely unflavoured mineral lip SPF, this may not be the right match — check the full ingredient list before buying.

How to use

Apply directly to clean, dry lips as part of your morning routine, reapplying through the day as needed — particularly after eating, drinking or extended sun exposure, in line with general SPF reapplication guidance. It can be worn alone or underneath lip colour.

Pairing with the rest of an iS Clinical lip routine

For lips that need more intensive overnight repair alongside daytime SPF, iS Clinical also offers the Lip Duo treatment system — a day-and-night duo that some customers use alongside Liprotect SPF 35 as a fuller lip-care routine.
