Mattifying Day Serum

Without doubt one of the best day serums on the market, this day serum has been specifically formulated to create a product that is at the cutting edge of technological advances in skincare. Offering products for both day and night protection, the serums are nourishing and light.

The mattifying hydrating serum is enriched with CITYSTEM to protect against pollution and GenoFix Day for holistic cellular protection. It is consistently rated five stars by our thousands of satisfied customers, with many asking: should I use a face serum twice a day? With our product, once a day is plenty to see the benefits of the day serum for your face.

As an anti-shine serum, the serum is designed to be used daily. It is the best day serum for acne prone skin as it can be worn alone or under make up. Can you use vitamin C day serum in the day? Of course!

Is this product suitable for me?

If you suffer from oily skin or facial redness, this face day serum is a delight and is the best day serum for the skin. It’s easily absorbed, non-greasy and creates a wonderful calm base on your face.

Our Mattifying Day Serum is designed to be used in the morning after cleansing. It creates a calming barrier for the skin. We’re often asked when to apply the day serum and whether to use the serum in the day or night - we always suggest the morning after cleansing your face for optimum results. We’re also asked if you should use the serum or a day cream first. The answer is always serum first. Think of it as your first line of defence against pollutants and irritants.

Our Mattifying Day Serum is not a peptide serum.

No - our serum works wonderfully well when used daily. You don’t need to be using the vitamin C serum twice a day; the best time of day to use the vitamin c day serum is after cleansing your face.

Cleanse your skin, then gently massage a small amount of serum into the face and neck in an upward, circular motion. Apply our Vitamin D Face Cream after the serum.

Our anti ageing day serum is formulated with cutting edge technology to soothe and hydrate. Enriched with jojoba and avocado oils, this anti-wrinkle intense hydration day serum is perfect to add into your skincare regime and makes it the best day serum for wrinkles.

Should you use a serum for both the day and at night? We advise yes. Our vitamin C serum can be used day or night, but we would recommend our Intensive Night Serum for evening application, since it provides intensive hydration overnight. Using a serum once or twice a day ensures 24 hour hydration and calming relief and, because of this, the mattifying day serum is the best day serum for oily skin. Because our entire range is scientifically formulated, we find it to be the best day serum in the UK.

The mattifying day serum is enriched with sunflower seed oil, packed with antioxidants to help with premature ageing and wrinkles. This best day serum for mature skin helps to keep skin looking fresh and linoleum acid helps retain the skin’s moisture to keep dryness at bay.

The best day serum for dry skin is one that contains natural ingredients. Our mattifying day serum does not contain retinol. It is the best day serum for sensitive skin.

The mattifying day serum is an excellent choice for combination skin. Simply use as directed in the morning and combine with our Intensive Night Serum in the evenings for complete protection and hydration.

The product is designed to go on the face, rather than directly on the lashes. Because all of our skincare range is vegan and cruelty free, you can be assured that our ingredients are gentle and calming near the sensitive eye area.
