How Long Does Sunscreen Last?

It’s important to keep in mind that if you’re using sunscreen correctly, it shouldn’t last you all that long.

Realistically, if you’re using sunscreen the way it’s directed, each bottle shouldn’t last you more than a couple of months. The recommendation is to put on a full ounce of sunscreen to cover the exposed parts of the body ― arms, legs, back, and chest.

The SPF protection found in sunscreen helps guard against:

  • Early skin aging
  • Skin damage
  • Skin cancer
  • Sunburns
  • Sunspots

An ounce is the size of a typical shot glass. And as most sunscreen bottles have about 4 ounces in them, you could be using the whole bottle in a single day or within a few weeks if you’re outside a lot.

But what about end-of-the-season sales? Most stores will offer marked-down sunblock to help get rid of inventory.

It might be okay, but you don’t know how the sunscreen was stored. It could have been kept in a hot warehouse all summer long. At that point, the active ingredients may have already gone bad.

When it comes down to it, it’s reasonable to replace sunscreen every summer ― or every month, if you’re using it often. If you don’t spend much time outside, store it in a cool, dry area over the winter.

While some manufacturers print the expiration date on the label or bottle, some don’t.

Write the date you got the sunscreen on the bottle to remember when it’s time to replace it. And remember that sunscreen can maintain its full strength for three years if stored properly.

Make sure your use sunscreen properly and practice the best skin care possible. Need more skin tips?

Caffeinated

Do Caffeinated Skincare Products Work?

When you need a morning jolt, a cup of joe typically does the trick. Can applying caffeinated creams and serums do the same for sleepy skin?

Let’s take a look at why beauty enthusiasts are abuzz about skin care products featuring caffeine and outline what exactly they can (and can’t) do for your skin.

Is caffeine good for your skin?

Caffeine has become a popular ingredient in skin care products ranging from under-eye serums to face masks to anti-cellulite creams and beyond. While marketing claims it can “wake up” your skin, here’s what that really means.

1. Protects skin from damage

Caffeine is an antioxidant, which is known to protect skin from damage caused by free radicals — molecules that break down your collagen and cause fine lines, wrinkles, and otherwise saggy, sallow skin.

2. Brightens the skin

Caffeine is a vasoconstrictor, which means it makes the blood vessels constrict, or tighten. That, in turn, reduces blood flow to the skin and makes your skin look brighter and smoother — like a real-life Instagram filter for your face!

3. De-puffs under-eye bags

Wake up with a huge hangover? Just didn’t get enough sleep last night. A caffeinated product may be just the trick to reduce the appearance of those dark circles and under-eye bags that come with general exhaustion.

That’s because it can help with microcirculation, which constricts the blood vessels and helps temporarily reduce discoloration in the skin. Say buh-bye — at least in the short term — to those dark circles under your eyes.

4. Soothes inflammation

When applied to the skin, caffeine’s anti-inflammatory properties help reduce redness and soothe skin inflamed by sun exposure (but try not to subject yourself to sun damage, to begin with!)

5. Reduces the look of stretch marks and cellulite

Caffeinated creams become particularly popular in the summer when people are preparing to bare them at the beach. That’s because they can be a quick fix to temporarily lessen the appearance of skin dimpled with cellulite and streaked with stretch marks.

Caffeine is known to stimulate enzymes that break down fats, so it can temporarily dehydrate fat cells. That results in a smoother and more firm appearance for a little while.

When using cellulite creams or stretch mark reduction products, the best way to apply them is to massage them into your skin. The massaging motion teams up with the caffeine itself to help stimulate those enzymes.

Caffeine’s benefits are short-term

Just like a cup of coffee only keeps you perked up for a few hours, so too do topical caffeinated products only provide benefits for a little while. That means they don’t cure wrinkles, fine lines, under-eye bags, and puffiness — just temporarily change their appearance.

If you’re a Harry Potter fan, think of it as a Polyjuice potion for pores: As soon as the product wears off, your face returns to its standard state. It might change the appearance of your skin in the moment, while you’re using it, but it’s not a treatment.

When to use caffeinated skin care products

Caffeinated skin care products are typically safe to use at any time, though if you’re using them for temporary tightening, brightening, and the like, it’s best to use them in the morning because remember: As the product wears off, so too will its benefits.
