Serums

What is a serum?

Skincare serums usually have a much higher concentration of active ingredients to deliver to the deeper layers of our skin. They can be more expensive than moisturisers due to their potency and efficacy.

What are the benefits?

Serums can be useful in the protection from free radical damage. Free radicals are the environmental aggressors that lead to premature ageing, sun damage and wrinkles. Vitamin C is a powerful antioxidant that can neutralise free radicals when they encounter the skin, making a Vitamin C serum perfect for keeping the skin youthful, soft and supple. Ferulic acids, Resveratrol and Vitamin E can help prevent oxidative stress that it is caused by UV exposure.

Some serums are fantastic for calming a reactive and irritated skin,  to reduce redness flare ups and breakouts. Serums can be formulated to be absorbed quickly making them beneficial for oily breakout prone skin as they will not leave a heavy residue.

Am I suitable?

There is a serum for everyone, however the potency of some active ingredients may be a little too strong for sensitive skins and may need working up to.

There are many different types of serums that can have many benefits bespoke to skin type and concern. Serums usually have hydrating acids such as hyaluronic acid and vitamins. Apply post cleanse and before moisturising.

Top Tips
  • Apply after cleansing and before moisturising
  • Check when to use your serum. Some are for use in the morning and others only at night.
