Supergoop Unseen Sunscreen Review: The Invisible SPF Explained

Supergoop Unseen Sunscreen SPF 40 is a clear, oil-free-feeling gel that works well as a makeup primer because it has no mineral filters and no water in its formula. Its Drug Facts label lists four chemical filters (avobenzone 3%, homosalate 8%, octisalate 5%, octocrylene 4%) in a base led by isododecane and silicone crosspolymers. It suits oily and combination skin best; very sensitive skin may do better with zinc oxide.

If you want to see how its ingredients line up with your own skin type, you can scan the barcode or photograph the label with the ingredient scanner in Pori (a Pro feature). Below we go through what is in the tube, why it disappears on skin, how it behaves under makeup, who it may irritate, what a full face of it really costs, and a cheaper formula with a near-identical base. This is an ingredient-and-evidence review; we didn't wear-test it ourselves.

What's in Supergoop Unseen Sunscreen?

Unseen is a chemical sunscreen with a silicone base. The current SPF 40 label lists avobenzone 3%, homosalate 8%, octocrylene 4% and octisalate 5% as the active ingredients. The inactive list starts with isododecane, dimethicone crosspolymer, dimethicone/bis-isobutyl PPG-20 crosspolymer and polymethylsilsesquioxane, then adds smaller amounts of caprylic/capric triglyceride, shea butter, meadowfoam estolide, red algae (Lithothamnion calcareum) extract, Boswellia serrata resin extract and tocopherol. There is no water and no fragrance on the published list.

Supergoop has also filed a newer Unseen Sunscreen SPF 50 label, dated June 2026, which raises octocrylene to 9%, sets homosalate at 7%, and keeps avobenzone 3% and octisalate 5%. That carton also shows a PA+++ UVA grade, the plus-sign system used on Japanese and other Asian sunscreens. Check which version you're buying, because the tubes look alike.

Why does Supergoop Unseen look invisible?

It goes on clear because none of its filters are white pigments. The American Academy of Dermatology (AAD) explains that sunscreens with titanium dioxide or zinc oxide are physical (mineral) sunscreens, and those are the ones that can leave a white residue; everything else is a chemical sunscreen. Unseen's four filters all dissolve into the base, so there are no particles to scatter light.

The texture comes from the base. Isododecane is a light, quick-drying solvent, and dimethicone crosspolymers are the same kind of silicone gels used in many face primers, which is why the finish feels velvety and slightly blurring instead of wet. Our explainer on dimethicone and silicones covers why these ingredients feel so different from creams and whether they clog pores. Because there's no water, there's also nothing to "dry down" in the way a lotion does, so it sets almost as soon as you spread it.

Can you use Supergoop Unseen as a primer?

Yes, and that's the main reason people buy it. A silicone gel fills in texture slightly and gives foundation a smooth surface to grip. The catch is pilling, those little rolls that appear when you rub one layer over another. Silicone gels tend to pill when they meet a layer that hasn't absorbed yet or that's built on a very different base.

• Give your moisturizer a few minutes before Unseen goes on, especially a water-based gel cream.
• Press, don't scrub. Spread it in one pass and pat the rest in instead of working it back and forth.
• Watch the base of your foundation. If one foundation pills over it and another doesn't, the foundation's base is the likely reason.
• Don't cut the amount to stop pilling. Using a thin smear makes it behave better under makeup and protect worse in the sun.

Is Supergoop Unseen good for oily skin?

For most oily and combination skin, the formula is a reasonable fit. The first four inactive ingredients are a volatile solvent and silicones, and the plant oils and butters (caprylic/capric triglyceride, shea) sit further down the ingredient list. There's no greasy cream base, and the silicone gel reads as matte-to-satin. That doesn't make it a guaranteed non-breakout product: acne response is individual, and the label makes no non-comedogenic claim. If oil control is your main goal, see our roundup of sunscreens for oily skin.

Dry skin may find it less comfortable on its own. A silicone gel gives slip, not much moisture, so it works best over a moisturizer.

Who might Supergoop Unseen irritate?

The people most likely to react are those who are sensitive to chemical filters, octocrylene in particular. A review in Contact Dermatitis found that photocontact allergy to octocrylene is seen mainly in adults who have previously used topical ketoprofen, an anti-inflammatory gel sold in Europe, while plain contact allergy is less frequent and appears mostly in children. The SPF 50 version has more than twice the octocrylene of the SPF 40.

The AAD notes that dermatologists recommend mineral sunscreens for people with sensitive skin. So if fragrance-free chemical sunscreens have stung you before, or you have rosacea or eczema that flares easily, a zinc oxide formula is the safer first try; our list of mineral sunscreens for sensitive skin is a good place to start. The plant extracts in the SPF 40 (red algae, Boswellia) are small in amount, but anyone with known botanical allergies should patch test. If you get a rash, the label's own instruction applies: stop and ask a doctor.

Are the chemical filters in Unseen safe?

They're legal and widely used, but the FDA has asked for more data on them. In its 2021 proposed sunscreen order, the FDA listed homosalate, octisalate, octocrylene and avobenzone among the filters for which "additional data is needed" to show they are generally recognized as safe and effective; that's a request for studies, not a finding of harm. An FDA-run trial found that avobenzone and octocrylene reached the bloodstream above the agency's screening threshold when sunscreen was applied heavily over most of the body four times a day, and the authors wrote that the results do not indicate people should stop using sunscreen. If you'd rather avoid the question entirely, choose zinc oxide or titanium dioxide, the only two filters that proposed order would classify as safe and effective.

How much Supergoop Unseen do you need, and what does it cost per use?

For the SPF on the tube, you need at least a teaspoon for your face. The AAD says to use at least 1 teaspoon on the face, about the length of your index and middle fingers, and to reapply every two hours outdoors and after swimming or sweating. A teaspoon is about 5 mL, so a 50 mL tube holds roughly ten full-face applications at that amount.

That's the number to do your price math with. Prices change with sales and sizes, so check the shelf price and divide by 50 for the cost per mL, or by about 10 for the cost per full application. For comparison, Biore UV Aqua Rich SPF 50 at $15.99 for 1.7 fl oz (50 mL), as of October 2026, works out to $0.32 per mL, or about $1.60 a face. Most silicone primers feel best in a thin layer, which is why a tube of Unseen seems to last for months; if yours does, you're probably using well under the tested amount. See how much sunscreen to use for the two-finger rule and reapplication.

The Skin Cancer Foundation notes that SPF 30 blocks about 97 percent of UVB rays. Unseen's SPF 40 clears the AAD's SPF 30 or higher recommendation, so the bigger risk is under-application, not the number on the tube.

What is a cheaper Supergoop Unseen dupe?

The closest look-alike we could confirm on the label is Olay Complete Invisible Facial Primer + Sunscreen SPF 35. Its Drug Facts list the same first three inactive ingredients as Unseen (isododecane, dimethicone crosspolymer and dimethicone/bis-isobutyl PPG-20 crosspolymer), with avobenzone 3%, homosalate 10%, octisalate 5% and octocrylene 10% as filters. It comes in a 60 mL tube and adds vitamin C (tetrahexyldecyl ascorbate), vitamin E and aloe.

The trade-off is more octocrylene and no water resistance. To find other look-alikes, read the inactive list: if isododecane and a dimethicone crosspolymer come first and there's no water, the texture will be in the same family.

Is Supergoop Unseen worth it?

It's worth it if you want a sunscreen that doubles as a primer, leaves no cast on any skin tone and won't feel greasy. Skip it, or try a mineral formula first, if you react to chemical filters or have very reactive skin. Whatever you choose, use a full teaspoon on your face, because a primer-thin layer won't give you SPF 40.
