Same SPF 50, opposite approaches: invisible chemical gel vs. gentle mineral lotion.
Supergoop Unseen is a clear, waterless gel built on four chemical filters (avobenzone, homosalate, octisalate and octocrylene). It leaves no white cast and feels like a makeup primer. Blue Lizard Sensitive is a lotion that uses only mineral filters, 10% zinc oxide and 8% titanium dioxide, with no fragrance and 80 minutes of water resistance.
So the choice comes down to your skin and where you’re putting it. For your face, especially under makeup or on deeper skin, Unseen is far easier to wear. If chemical sunscreens make your skin sting, or you’re covering kids, arms and legs at the pool, Blue Lizard is gentler, tougher in water and costs a fraction as much per ounce.

Blue Lizard is water resistant for 80 minutes; Unseen for 40. Blue Lizard also comes in a 5 fl oz tube that costs a fraction as much per ounce, which matters when you’re covering arms, legs and kids. Unseen is a face product: using it from head to toe gets expensive fast.
Water resistance tells you when to reapply after swimming, not how long the sunscreen lasts all day. Reapply every two hours outdoors, and right after toweling off.
Supergoop Unseen SPF 50: the invisible face option
Clear, primer-like face gel with no white cast.
Unseen uses four chemical filters: 3% avobenzone, 7% homosalate, 5% octisalate and 9% octocrylene. There’s no water in the formula. Isododecane and silicone crosspolymers make it a clear, slippery gel that dries to a smooth, velvety finish, so it doubles as a makeup primer.
With no mineral particles, it leaves no white cast on any skin tone. It’s water and sweat resistant for 40 minutes and has no added fragrance. Red algae extract, shea butter and vitamin E round out the list.
Skip it if chemical filters have made your skin sting or flush before. It’s also a 1.7 fl oz tube that costs far more per ounce than Blue Lizard, so keep it for your face.
- No white cast on any skin tone
- Smooth, primer-like finish under makeup
- Water and sweat resistant for 40 minutes
- Chemical filters only, not for mineral-only routines
- Costs far more per ounce than Blue Lizard
- Silicone-heavy, which some acne-prone skin dislikes
Blue Lizard Sensitive SPF 50: mineral-only and water resistant
Zinc and titanium lotion for reactive skin and body.
Blue Lizard Sensitive uses only mineral filters: 10% zinc oxide and 8% titanium dioxide. Mineral filters are the least likely to irritate, which makes this a go-to for skin that stings with chemical sunscreens, and for kids. There’s no fragrance, and it’s water resistant for 80 minutes.
The base is a classic lotion of silicones, esters such as C12-15 alkyl benzoate and ethylhexyl palmitate, and candelilla wax, with aloe and vitamin E. That makes it richer than Unseen, and 18% mineral filters leave a visible white layer that’s hardest to blend on deeper skin. The Smart Cap turns color in strong UV light as a reminder to reapply.
A 5 fl oz tube costs a fraction as much per ounce as Unseen, so it’s the practical pick for arms, legs and beach days.
- Mineral-only: 10% zinc oxide, 8% titanium dioxide
- Fragrance-free
- Water resistant for 80 minutes
- Costs a fraction as much per ounce as Unseen
- Leaves a visible white cast, especially on deeper skin
- Richer, heavier feel than a face gel
- Not designed to sit under makeup
Blue Lizard Sensitive SPF 50+ two-pack: for families
- Two 5 fl oz tubes, 10 oz total
- Mineral-only, fragrance-free and water resistant for 80 minutes
- Color-changing Smart Caps signal strong UV
- Only worth it if it costs less per tube than the single
- Occasional users may not finish both tubes
Sensitive skin, white cast and reapplying
Are chemical filters worse for sensitive skin?
Not for most people, but mineral filters are the usual first choice if your skin stings, flushes or itches with regular sunscreen. Zinc oxide and titanium dioxide rarely cause reactions, which is why Blue Lizard Sensitive uses only those two. If chemical sunscreens have never bothered you, Unseen is fine.
Will Blue Lizard leave a white cast?
Yes, some. With 10% zinc oxide and 8% titanium dioxide, it leaves a visible white layer that fades as you rub it in but rarely disappears on medium to deep skin. Unseen leaves none.
Does SPF 50 mean I can reapply less often?
No. Reapply either one every two hours outdoors. Blue Lizard is water resistant for 80 minutes and Unseen for 40, so reapply sooner after swimming, sweating or towel drying.
Is the Blue Lizard two-pack worth it?
Only if you go through a lot of sunscreen, such as a family at the pool every weekend. Compare the live price per tube with the single; if the pack isn’t cheaper, buy one tube at a time so none expires on the shelf.
Choose Supergoop Unseen SPF 50 for your face if you want sunscreen you can’t see. It’s a clear, waterless silicone gel with four chemical filters, no white cast on any skin tone and a primer-like finish that works under makeup.
Choose Blue Lizard Sensitive SPF 50 if chemical filters bother your skin, or for body, kids and beach days. It relies only on 10% zinc oxide and 8% titanium dioxide, has no fragrance, lasts 80 minutes in water and costs a fraction as much per ounce. Expect a visible white layer, especially on deeper skin.
You can also split the job: Unseen on your face, Blue Lizard everywhere else. Get the Blue Lizard two-pack only if your household goes through sunscreen fast.
