Buying Guide: How to Choose the Best Moisturizer With Spf

A moisturiser with SPF is arguably the most important step in any skincare routine. It simplifies your morning by combining hydration and sun protection into one product. But with so many options, choosing the right one can be tricky. Here’s what to consider to make an informed choice.

Understand SPF and Broad-Spectrum Protection

SPF (Sun Protection Factor) primarily measures protection against UVB rays, which are responsible for sunburn. For daily use, an SPF of 30 is the minimum recommended by dermatologists, but SPF 50 or 50+ provides a higher margin of safety.

Broad-Spectrum Protection is non-negotiable. This means the product also protects against UVA rays, which penetrate deeper into the skin and are the main cause of premature ageing (wrinkles, fine lines) and can contribute to skin cancer. In the UK and EU, look for the letters "UVA" in a circle on the packaging, which indicates it meets the standard.

Chemical vs. Mineral Sunscreen Filters

Sunscreens work using two types of filters, and many moisturisers use a combination of both.

• Chemical Filters: Ingredients like Avobenzone, Octocrylene, and Mexoryl work by absorbing UV radiation and converting it into heat, which is then released from the skin. They tend to be more lightweight and sheer, leaving no white cast. However, they can sometimes cause irritation in very sensitive skin.
• Mineral Filters: Ingredients like Zinc Oxide and Titanium Dioxide create a physical barrier on the skin that reflects UV rays. They are generally better tolerated by sensitive or reactive skin but can sometimes feel heavier or leave a visible white cast, although modern formulas have improved significantly.

Select for Your Skin Type

The "moisturiser" part of the product is just as important as the SPF. The base formula should suit your skin's needs.

• Oily or Acne-Prone Skin: Look for labels like "oil-free," "non-comedogenic" (won't clog pores), and "mattifying." Lightweight lotions or fluid textures are ideal. Ingredients like niacinamide can help regulate oil production.
• Dry Skin: Choose creamier, richer textures with hydrating ingredients like hyaluronic acid, glycerin, ceramides, and squalane to lock in moisture and prevent dryness throughout the day.
• Sensitive Skin: Opt for fragrance-free formulas. Mineral-based sunscreens are often a safer bet. Look for soothing ingredients like Avene's Thermal Spring Water, oat extract, or calendula.
• Combination Skin: A lightweight lotion that provides balanced hydration without being too heavy is usually the best choice. The CeraVe AM Lotion is a great example of a product that works well for this skin type.

Consider Additional Skincare Benefits

Many modern SPF moisturisers are packed with extra ingredients to target specific concerns, allowing you to streamline your routine even further.

• Antioxidants: Vitamins C and E help protect the skin from damage caused by free radicals and pollution.
• Niacinamide (Vitamin B3): A versatile ingredient that can help with redness, pore size, oil control, and improving the skin barrier.
• Hyaluronic Acid: A powerful humectant that draws moisture into the skin, keeping it plump and hydrated.
• Peptides: Amino acid chains that can help to firm the skin and stimulate collagen production, providing anti-ageing benefits.

Application is Key

To get the advertised SPF rating, you need to apply enough product. A common guideline is the "two-finger rule": squeeze a line of product onto your index and middle fingers, and apply that amount to your face and neck. Remember to reapply every two hours if you are in direct sun, sweating, or swimming.
