The best radiance serums to brighten dull skin | Our top picks

Skin acts as the body's first line of defence, protecting it against many external factors. Therefore, taking good care of our skin and striving to keep it healthy and radiant is vital. We all aspire to have glowing skin and this is partly due to its strong connection within the health and beauty industry, and the world of celebrity.

Radiance serums are beneficial in this regard, as they focus on brightening dull skin to create a healthy glow. However, when choosing brightening and radiance serums, it is important to be aware of certain characteristics, their key ingredients (known as active ingredients), and potential side effects to find one suitable for your skin type.

How does serum brighten skin?

Face serums, such as radiance and hydrating serums, are lightweight, concentrated formulas concocted to deliver active ingredients topically. With a high concentration of ingredients such as vitamin C, these serums target certain issues due to their molecular structure and penetrate the deepest layers to create a smooth complexion.

Brightening serums contain key ingredients targeting discolouration or pigmented areas that dull the skin, including common issues like redness. These hydrating elements can help soothe and improve skin tone, creating a youthful, healthy-looking glow and reducing blemishes on the face.

What are the key ingredients to look for in radiance and brightening serums?

With various options available, understanding the active ingredients can help you choose a serum. To help brighten dull skin and create a glow, look for these key ingredients in your next radiance serum:

  • Vitamin C: This ingredient keeps the skin bright and clear by blocking further pigment production. Vitamin C is a common ingredient in radiance and other serums for different purposes. Try this Murad Vita-C Brightening Serum, featuring vitamin C and glycolic acid.

  • Niacinamide: A construct of vitamin B3, niacinamide targets redness and enlarged pores, making it an ideal hero for those with oily skin. Similar to hyaluronic acid, this is a water-soluble moisturiser that helps correct uneven skin tone and promotes skin elasticity to make skin appear youthful. Try this Niacinamide Serum by The Inkey List if you have oily skin.

  • Retinol: Perfect for anti-ageing in addition to dull skin, retinol helps increase cell turnover and prompts an exfoliation effect to make skin brighter and clearer. Try this La Roche-Posay Retinol Serum.

  • Azelaic acid: This active ingredient has anti-inflammatory properties and is a natural skin brightener. Serums containing azelaic acid are often good for treating acne and rosacea, evening skin tone, and decreasing pigmentation.

Frequently asked questions

How do you apply a face serum?

Dispense a small amount (pea-sized) into your palms and lightly press your face and neck, making outward and upward motions. Remember that a little goes a long way.

What other skincare products can be used along with radiance serums?

Finding a skincare routine that complements your skin type and the specific concerns you are looking to address can be difficult. Apply a cleanser and a water-based toner before a brightening serum to help hydrate and prepare the skin for the serum.

Ensure you give enough time after applying a serum for it to absorb into the skin and follow this with a moisturiser.

When should you use a radiance serum?

This simple routine can be used both in the morning and at night with slight adjustments. In the morning, follow the serum with a moisturiser and SPF to protect the skin from UV damage.

However, it is important to remember that certain active ingredients should not be mixed, as they can counteract each other. Make sure you check the ingredients of your skincare products carefully.
