Can We Apply Sunscreen at Night: Breaking Down the Facts

It is well known that sunscreen is an essential daytime shield against sunburn, premature ageing, and hyperpigmentation. But in recent years, a curious question has made its way into our skincare routines — can we apply sunscreen at night?

CodeSkin understands the confusion. After all, if sunscreen protects your skin, why not use it round the clock? Let us break this down clearly and compassionately so you can make choices that truly benefit your skin.

Understanding Sunscreen and Its Purpose

Sunscreen is designed to protect your skin from the harmful effects of ultraviolet (UV) rays — specifically UVA and UVB. These rays are responsible for DNA damage, collagen breakdown, and pigmentation issues. Broad-spectrum products like our UltraProtect Fluid Sunscreen SPF 100+ act as a barrier, either by absorbing or reflecting these rays.

During the day, especially when exposed to direct sunlight or even incidental exposure through windows, sunscreen plays a vital role. But at night, the presence of UV rays is virtually nonexistent, making its core protective function less relevant. 

Benefits of Using Sunscreen at Night

Although traditionally applied during the day, if you’re wondering can we apply sunblock at night, you can! There are a few valid reasons why many people do it; these include:

1. Added Protection from Artificial Light Exposure

Spending long hours in front of screens? Blue light can stress your skin. A formula like our UltraProtect Fluid SPF 100+ offers support during late-night screen time or meetings.

2. Support for Skin in High-Exposure Environments

Even under streetlights or bright event setups, your skin is still exposed. A quick layer of protection can help, especially with breathable textures like our UltraLite Fluid SPF 50+.

3. Hydration and Skin Comfort

Some sunscreens are light, airy, and hydrating. If you’re not in the mood for a rich night cream, a gentle, skin-cushioning SPF can feel surprisingly comforting.

4. Calming Care for Sensitised Skin

When your skin feels a bit irritated, maybe from the weather or too much cleansing, a mineral sunscreen can feel soothing. It adds comfort without weighing your skin down.

Risks of Using Sunscreen at Night

Sleep is when your skin enters its natural repair mode. Sunscreens, especially those with occlusive or water-resistant textures, may not support this process. Potential concerns include:

• Reduced skin breathability

• Product build-up leading to dullness or breakouts

• Missed opportunity to apply targeted barrier-repair treatments

Instead, this is the ideal time to use a nourishing moisturizer infused with epidermal growth factors or NAD technology. For instance, CodeSkin’s UltraIntense Moisturizer supports overnight regeneration.

Are There Any Reasons to Apply Sunscreen at Night?

If you’re still questioning do you need sunscreen at night, the answer depends on your environment. In certain scenarios, it might be worth considering, like:

• If you're exposed to high-intensity artificial light or screens for long hours

• If you're outdoors under artificial lighting for extended periods

• If your sunscreen includes added skincare benefits like antioxidants or calming agents

That said, your skin's primary need at night is restoration. Unless you fall into one of the above categories, prioritising repair-focused skincare is usually more beneficial.

When Should You Apply Sunscreen in Your Skincare Routine?

Sunscreen should always be the last step in your morning routine. It’s typically applied after moisturizer and before makeup. If you're exposed to light in the evening, reapplication may be helpful. At night, after cleansing, shift focus to hydration and repair using barrier-strengthening ingredients.

FAQs on Applying Sunscreen at Night

1. Does sunscreen work at night?

Yes, but only in limited ways. Its main purpose is UV protection, which isn't required after dark. However, formulas with antioxidants or blue-light filters may still provide benefits in certain environments.

2. Can I skip sunscreen at night if I’m indoors?

Yes. If you are indoors during the night with minimal exposure to screens or bright artificial lights, there is no reason to apply sunscreen.

3. Is there any harm in using sunscreen at night?

There’s no direct harm in using sunscreen at night. If your sunscreen is thick or not designed for long wear, then it could feel heavy or clog pores. Thus, choosing a nutrient-rich night moisturizer is usually a better option.
