Frequently Asked Questions

What is a face serum, and how is it different from a moisturiser?

A face serum is a lightweight, fast-absorbing skincare product designed to deliver a high concentration of active ingredients deep into the skin. Serums typically target specific concerns like pigmentation, brightening, dehydration, or ageing, with potent actives such as vitamin C, peptides, or vitamin A. Unlike moisturisers, which focus on hydration and creating a barrier, serums are formulated to treat and boost skin health at a deeper level. For best results, we recommend using both; apply serum first, then follow with moisturiser.

What is the best serum for glowing skin?

To brighten the complexion, look for ingredients like vitamin C, a powerful antioxidant that helps revive dull skin and enhance natural glow. For uneven skin tone, actives such as niacinamide are proven to visibly reduce dark spots and discolouration.

At Medik8, our brightening serums are expertly formulated to tackle both concerns at once. By improving uneven tone, skin appears clearer and more luminous, unlocking a visibly radiant, glowing complexion over time. C-Tetra Luxe is packed with stabilised vitamin C to boost radiance, reduce pigmentation, and protect against environmental damage, leaving the skin visibly brighter and more radiant.

What is the best night serum to use?

The best night serum depends on your skin concerns, but serums containing retinoids or peptides are perfect for nighttime repair. Medik8’s Crystal Retinal is a powerful retinal-based night serum that helps smooth wrinkles and brighten the complexion while you sleep.

Should I use a serum before or after moisturiser?

Serums should be applied after cleansing and before moisturising. They deliver active ingredients deep into the skin, and a moisturiser can then lock in hydration and provide an extra layer of protection.

How do I choose the right face serum for my skin type?

Choose a serum based on your skin concerns. For hydration, try Hydr8 B5 Intense. For mature skin and ageing concerns, Crystal Retinal and Liquid Peptides Advanced MP are ideal for smoothing wrinkles. For brightening and radiance, opt for C-Tetra Luxe. If you have combination or oily skin, look for lightweight, non-comedogenic serums that hydrate without clogging pores, such as Clarity Peptides: a gentle, balancing formula ideal for blemish-prone skin.

At Medik8, we formulate each serum with specific skin concerns in mind, so you can build a targeted routine with confidence and ease.

Are Medik8 face serums vegan?

Yes, many of Medik8’s serums are certified by the Vegan Society. Serums like C-Tetra and Super C Ferulic are formulated without animal-derived ingredients, making them suitable for those seeking a vegan-friendly skincare routine.
