Background

CD81 is a member of the transmembrane 4 superfamily and it is a cell surface glycoprotein that is known to complex with integrins. CD81 appears to promote muscle cell fusion and support myotube maintenance. Also it may be involved in signal transduction. Moreover, CD81 plays a critical role in Hepatitis C attachment and cell entry by interacting with virus' E1/E2 glycoproteins heterodimer. The large extracellular loop of CD81 binds the hepatitis E2 glycoprotein dimer. It also appears to play a role in liver invasion by Plasmodium species.

Dry-touch but still uncomfortable to wear
It didn't rub in like regular sunblock, I suppose because the of the 'dry-touch'. But I could still feel it on my skin and was a little bit itchy. If you continue to rub it actually kind of peels away-then obviously negating putting it on in the first place. :(

It is a great sunscreen.
I love it, because it is no greasy and it feels like you don't have it on your face. It is a little expensive comparing to others but I think it is a good choice.

Have used it for years
One of the the best on the market because it is a broad spectrum sunscreen protecting against both UVA and UVB rays. But as with all lotions it must be reapplied after several hours.

Lightweight sunscreen for face, 30 spf, everyday mix with foundation
Style: Face Lotion - SPF 30, Size: 1.7 Fl Oz (Pack of 1)
Great sunscreen and it is travel size! This suscreen is 30 spf, has a yellow tint, which works well as a facial sunscreen, while toning redness. It mixes well with three types of foundations. It is not sticky, absorbs well. Smells good.

VERY GOOD, but not for me ┐('~`ˇ)┌
Style: Face Lotion - SPF 30, Size: 1.7 Fl Oz (Pack of 1)
PRODUCT [Hawaiian Tropic Weightless Hydration Lotion Sunscreen for Face SPF 30 1.7oz] PROs - Was delivered on time + well packaged + undamaged - Was a described/depicted per Amazons description (design and color is exactly as shown in the product picture) - Rubs/dissolves into face well - Felt slightly "weightless" - NO WHITE CAST - Felt moisturizing - GOOD price for the amount and value - VEGAN!! DID NOT BREAK OUT my picky, sensitive skin! CONs - Felt kinda "greasy" to me Overall, the product was GOOD, BUT JUST WASN'T FOR ME. The primary face moisturizer I use is oil based, and something that is a must for my skin (My skin loves my moisturizer). SO, having an oil based moister, and a GREASY sunscreen, is gonna be a no for me.
