No problem, @LannaW ! Yeah, definitely use sunscreen all year long during daylight hours. The sun doesn't stop beaming UV rays once summer ends, and overcast weather doesn't block 'em all—especially not UVA rays. You should also wear sunscreen if you'll be sitting beside a window with open curtains/blinds, or riding in a car/bus/train/etc. that doesn't have UV-tinted windows. UVB rays are blocked by windows, but not UVA rays.
The right sunscreen for your skin depends a lot on your personal preferences. Which sunscreen do you use in the summer?
Many people (including me) love Supergoop! Unseen Sunscreen SPF 40 PA+++ , but some folks don't like how siliconey it feels when first applied. On my mostly-dry combo skin, this sunscreen always settles down to a natural skin finish that doesn't feel greasy. My skin's quite reactive/inflammation-prone and I've yet to have issues using this sunscreen. Your experience could be different, of course.
La Roche-Posay makes very good sunscreens, but some of them can feel greasy, especially their Anthelios SPF 100 which I love to use in the winter: it's an extra layer of moisturization (in Chicago winter, I always need a separate moisturizer under my sunscreen; in summer, I can get away with skipping moisturizer and relying on a moisturizing sunscreen), plus it makes my skin super glowy in below-freezing weather. 😄 I can't use that sunscreen in summer though: it just feels too heavy on my skin in hot weather.
A good mineral sunscreen that doesn't feel heavy and greasy on me is Dermstore Daily Mineral Sunscreen Sheer Tint SPF 40. This one's tinted but not heavily; the tint's just meant to mask the white cast zinc oxide leaves on skin. This sunscreen's available only at Dermstore's site. I also love Native Unscented Face Sunscreen SPF 30, though some folks might find it feels a bit heavy on their skin.
Another option is ordering a Japanese or Korean sunscreen from places like YesStyle, Olive Young, Stylevana, Pink n Blossom (they're based in Canada), Jolse, etc. These sunscreens tend to use newer, more innovative, and apparently more effective UV filters (like newer uvinals and tinosorbs) than the ones allowed in US sunscreens. Beauty of Joseon Relief Sun SPF 50 is one of those Korean sunscreens. The only downside, particularly for Japanese sunscreens, is frequent product reformulation: for some reason, skincare brands in Japan like to reformulate their products seemingly every year or two. One of my favorite sunscreens was the Canmake Mermaid Skin Gel UV SPF 50 (the clear version), until Canmake reformulated it to something I can't use on my skin (they added an ingredient my facial skin hates).
If you want to try a tinted moisturizer type of sunscreen (something with a stronger tint than the Dermstore sunscreen I mentioned, strong enough to work as a sheer to medium coverage skin tint), remember that you'll still need to apply it generously to get adequate protection. There's no such thing as "a little goes a long way" with sunscreen, and you want at least SPF 30. If you have a local Sephora, see if they have
Saie Slip Tint Dewy Tinted Moisturizer Five
(can't tag it without a specific shade) in-store so you can swatch different shades in person. Some people love
ILIA Super Serum Skin Tint SPF 40 Foundation Dominica ST14
; I didn't like it at all, but again, it's all about personal preference.
