When To Apply Sunscreen? A Complete Guide

Sunscreen is a crucial part of any skincare routine, protecting from harmful UV rays that can lead to skin damage, premature ageing, and an increased risk of skin cancer. But the question often arises—when exactly should you apply sunscreen? Should it only be a part of your morning routine, or can I apply sunscreen at night? In this blog, we’ll answer these questions and break down the importance of sunscreen application during different times of the day.

When To Apply Sunscreen On Face – AM Application

The morning is undoubtedly the most essential time to apply sunscreen. When you step outside, whether it's sunny, cloudy, or even raining, your skin is exposed to UV radiation. Even indoors, UV rays can penetrate through windows and affect your skin.

1. When To Apply?

It’s ideal to apply sunscreen every morning as the last step in your skincare routine, right before makeup. Apply it at least 15–30 minutes before you step out so that the formula has time to absorb into your skin.

2. Why Is It Important?

• Protection From UVB & UVA Rays: UVB rays cause sunburn, while UVA rays penetrate deeper, contributing to premature ageing and skin cancer. Sunscreen shields your skin from both.

• Daily Exposure: Whether you’re commuting to work or sitting near a sunny window at home, UV exposure adds up over time, leading to long-term damage.

3. Reapplication

If you spend extended periods outside or sweat a lot, it’s recommended to reapply sunscreen every two to three hours. For regular daily activities, one-morning application is fine. However, it is recommended to keep your exposure levels in mind for reapplication.

When To Apply Sunscreen On Face – PM Application

While it's commonly known that sunscreen is a must for the daytime, is there any need to apply sunscreen in the evening or at night? Generally, it isn’t required once the sun has set, but there are a few exceptions.

1. Exceptions To Apply Sunscreen At Night

• Evening Outdoor Activities: If you're heading out for a late afternoon or evening run, picnic, or any other outdoor event, you might still need sunscreen. In some regions, UV radiation remains strong until the evening, and your skin can still get sun exposure.

• Under Artificial Lights: For those concerned about visible light from screens or certain types of indoor lighting that can emit low levels of UV radiation, you might consider applying sunscreen even during the evening. However, most experts agree that standard nighttime skincare routines don't require sunscreen unless you're still exposed to sunlight.

2. When Not To Apply Sunscreen At Night?

Once the sun has set and you're spending your time indoors, it's safe to skip sunscreen. Instead, focus on hydrating and repairing your skin with night creams or serums that contain antioxidants, peptides, or retinoids to counteract any sun damage from the day.

What Is The Correct Order Of Using Sunscreen?

Applying sunscreen in the right order within your skincare routine ensures that you get the full benefits of all your products without compromising protection.

• Step 1: Start with a clean face by using a gentle face wash to remove any dirt, oil, or makeup.

• Step 2: If you use a toner, apply it next. A face toner helps in prepping your skin for further steps and balancing pH levels.

• Step 3: Follow up with any targeted treatments like hyaluronic acid or vitamin C and niacinamide serum. These are lightweight and should go underneath heavier products.

• Step 4: Apply your day cream to hydrate and protect your skin barrier.

• Step 5: Finish your skincare routine with a broad-spectrum sunscreen. This ensures that it forms a protective layer over your skin, without being diluted or disrupted by other products.

• Pro Tip: When using sunscreen, make sure to apply enough—approximately a quarter-sized amount for your face and neck. Don’t forget often-missed areas like the ears, back of the neck, and hands.

Sunscreen is non-negotiable when it comes to protecting your skin from UV rays and maintaining a youthful, healthy complexion. The best time to apply sunscreen is every morning as part of your skincare routine, and don't hesitate to reapply during the day, especially if you're spending time outdoors. While PM application is less common, it’s essential for evening activities where UV exposure may still be a risk. By using sunscreen consistently and correctly, you’ll be giving your skin the protection it needs to stay healthy and radiant for years to come.
