Supergoop Unseen Sunscreen SPF 40 Review

Supergoop Unseen Sunscreen SPF 40 disappears on every skin tone because it holds no mineral filter and no pigment. Buy it for the finish under makeup, not for protection per dollar. Supergoop has since replaced the face version with an SPF 50, so anything you find now is leftover stock, and at its last brand list price of $38 for 1.7 fl oz it cost 73% more per fl oz than the Unseen body gel at the same labelled SPF.

This review covers the original SPF 40 face liquid, not the SPF 50 that replaced it, and not the Unseen body gel, stick, lip product or Mineral Unseen.

Key points

• Its last list price on supergoop.com was $38 for 1.7 fl oz, with $22 for 0.68 fl oz and $48 for 2.5 fl oz, archived 24 December 2024. That works out to $22.35 per fl oz.
• Actives are avobenzone 3%, homosalate 8%, octisalate 5% and octocrylene 4%.
• The 8% homosalate sits above the 7.34% ceiling for face products set by Commission Regulation (EU) 2022/2195. The SPF 50 replacement uses 7%.
• No zinc oxide, no titanium dioxide, no pigment, no water and no humectant anywhere in the inactive list.
• Supergoop's Unseen collection now lists the face product only as SPF 50, and the old SPF 40 face page returns a 404, checked 26 August 2026.

What is Supergoop Unseen Sunscreen SPF 40?

An anhydrous, silicone-based chemical sunscreen sold as a makeup primer. Isododecane heads the inactive list, a fast-evaporating solvent carrying three silicone elastomers that leave a dry, faintly blurred film behind. Supergoop built the brand on suncare people will actually wear daily, and Unseen is the product that won the argument.

It behaves like a smoothing primer. Clear going on, matte within a minute. Foundation then grips it instead of sliding around on it. Nothing about wearing it says sunscreen, which is both the appeal and the risk.

Has the SPF 40 been replaced by SPF 50?

Yes, for the face liquid. Checked 26 August 2026, supergoop.com lists the Unseen face product only as SPF 50, priced at $19 for 0.68 fl oz, $38 for 1.7 fl oz and $48 for 2.5 fl oz. The old SPF 40 face page returns a 404. SPF 40 survives in Unseen Sunscreen Body SPF 40 at $44 for 3.4 fl oz and Unseen Sunscreen Stick SPF 40 at $32 for 0.70 oz, both different formulas.

The SPF 50 raises octocrylene from 4% to 9%, cuts homosalate from 8% to 7%, and adds bisabolol, dipotassium glycyrrhizate and diethylhexyl syringylidenemalonate. Supergoop's own page credits its new polymers with "a lighter-weight feel and a smoother glide", footnoted as a comparison against the original SPF 40. The brand is telling you which texture was the heavier one.

What are the key ingredients in Unseen Sunscreen SPF 40?

Four filters totalling 20%: avobenzone 3% for UVA, homosalate 8% and octisalate 5% for UVB, and octocrylene 4%, there mainly to slow avobenzone's breakdown in light. That is a light photostabiliser load for a formula leaning on avobenzone alone for UVA. Supergoop more than doubled it in the replacement, which reads as the brand's own verdict on the original.

Positions two, three and four of the inactive list are dimethicone crosspolymer, dimethicone/bis-isobutyl PPG-20 crosspolymer and polymethylsilsesquioxane. Those three elastomers do the blurring. Microcrystalline cellulose, diatomaceous earth and silica sit near the very end of the list, so the oil-absorbing load behind the matte finish is small. Supergoop described the formula as free of pore-clogging oils, and shea butter, jojoba esters and meadowfoam estolide still sit mid-list as emollients.

Does Unseen Sunscreen leave a white cast?

No, and it cannot. White cast comes from mineral filters scattering light, and the inactive list holds no zinc oxide, no titanium dioxide and no pigment. There is nothing in the formula that can go grey on deep skin. That single fact built its reputation.

Does Unseen Sunscreen pill?

This is its real weakness, and it is written into the formula. Silicone elastomer gels do not disperse into water. They sit on top of water-based layers. Put this over a hyaluronic acid serum, a gel moisturiser or anything thickened with carbomer, and the film rolls into grey threads under your fingers. Letting the layer underneath dry fully, then pressing rather than rubbing, reduces it. A sunscreen at $22.35 per fl oz that needs a technique is still a sunscreen that needs a technique.

How does Unseen Sunscreen SPF 40 perform?

As a primer, well. It held 4.8 out of 5 from 4,261 reviews on supergoop.com as archived on 24 December 2024. The SPF 50 that replaced it holds 4.7 out of 5 from 5,712 reviews on the same site, checked 26 August 2026.

As sun protection, everything depends on dose. The slip invites a thin, primer-sized layer, and a thin layer of any SPF 40 delivers far less than 40. Roughly a quarter teaspoon is the face dose the rating assumes, and that much of this product feels heavy for its first minute on skin.

How much does Unseen Sunscreen SPF 40 cost?

$38 for 1.7 fl oz was the last list price on supergoop.com, archived 24 December 2024, which is $22.35 per fl oz. Unseen Sunscreen Body SPF 40 is $44 for 3.4 fl oz on supergoop.com, checked 26 August 2026, or $12.94 per fl oz. Same labelled SPF, 73% more per fl oz for the face version.

With the face formula gone from the brand's own line-up, third-party pricing moves around. Buy from a retailer with a returns policy and check the batch date. Avobenzone systems do not improve with age, and 4% octocrylene gives this one less help holding together than the replacement gets from 9%.

Is Unseen Sunscreen SPF 40 worth the price?

If you wear makeup most days and sunscreen has been wrecking it, yes. If the price is the sticking point, our guide to Supergoop Unseen Sunscreen dupes covers what matches the finish and what each alternative gives up in exchange.

As protection first, no. You are paying for cosmetic elegance on a filter system that is legal in the US but sits above the EU's face limit for homosalate. Products over that limit could not be placed on the EU market from 1 January 2025 and could not be sold there at all from 1 July 2025.

Pros and cons

Pros

• No mineral filter and no pigment, so no white cast on any skin tone
• Grips foundation rather than letting it slide
• Scentless, and matte inside a minute
• 4.8 out of 5 from 4,261 reviews on supergoop.com, archived December 2024

Cons

• $22.35 per fl oz, 73% more than the body version at the same labelled SPF
• The silicone elastomer base pills over water-based serums and gel moisturisers
• Homosalate 8%, above the EU's 7.34% face cap
• Octocrylene 4%, under half the photostabiliser load Supergoop put in the SPF 50
• No water, no humectant and no soothing agent in the formula
• Gone as a face product, so any stock you find is ageing

Who should buy Unseen Sunscreen SPF 40?

People who wear foundation most days and want one step doing two jobs. Combination and oily skin get on with it best. Anyone with deep skin who gave up on mineral formulas after years of grey flashback will see immediately why this one has the reputation it does. If you turn up leftover SPF 40 under $30 and already know the texture suits you, take it.

Who should skip it?

Skip it if your routine runs on hydrating serums or gel moisturisers, because you will be managing pilling every morning. Skip it if your skin is dry: there is no water and no humectant here, and the film sits over flaking instead of smoothing it. Skip it if you reapply over makeup during the day, since this needs a full even layer and cannot be patted on top of foundation. Skip it if you avoid homosalate or octocrylene. And skip it if you want a product still stocked next year, in which case buy the SPF 50, which is the same idea with more octocrylene and less homosalate.
