What Are Serums?
Serums are formulas which have a concentration of active ingredients and contain vitamins and antioxidants. They are composed of small molecules which can quickly penetrate the deeper dermis layer of the skin. Serums can help with skin concerns such as the visible signs of stress, aging, sensitivity and sun damage on the skin.
Types Of Serums
Serums for Dry Skin
Serums for dry skin often contain hydrating ingredients such as Vitamin E, Hyaluronic Acid, Niacinamide, and Squalene, as well as Vitamin C.
Serums for Skin Brightening
Brightening serums often contain vitamin C which can assist with pigmentation issues and Glycolic Acid Ferulic acid which have exfoliating properties.
Serums for acne often contain ingredients such as Retinol and Salicylic Acid which help to unclog pores. Zinc has anti-inflammatory properties and Vitamin C help with acne scarring.
Vitamin C, Plant-based Glycerin are common anti-aging serum ingredients.
Vitamin C has many positive skincare benefits and is used across all categories of serums: anti-aging, hydrating, acne and skin brightening. Learn more about Vitamin C Skincare Facts and Fiction.
Serum Vs. Moisturiser?
Moisturisers are creamier and serve to hydrate skin and help prevent moisture loss. Serums have concentrated ingredients and smaller particles which penetrate to the deeper dermis layers of your skin. When used together, moisturisers lock in your serum, and the serum can enhance the hydrating effects of your moisturiser.
How to apply a Serum?
You only need a very small amount of serum to your face. Always read the instructions on the bottle, 2-3 drops or 1-2 pumps is often recommended. Apply to clean skin after using skin toner and before your moisturiser.
Can You Mix Serums?
Yes and No. There are some ingredients which are more potent than others such as Retinol, aha (Alpha Hydroxy Acids) and some peel or acne serums which may be intended for a specific use. Speak with a skincare specialists or dermatologist to determine what’s best for your skin and the result you’re after.
Many serums, such as botanical serums mix and complement each other very well.
When layering serums, start with the thinnest, lightest formulas and apply thicker formulas over the top. (We love to layer the Midnight Recovery Concentrate – made from 99.8% natural ingredients - over the Powerful-Strength Line-Reducing Concentrate) The Vitamin C and Squalene in these formulas work well together.
When To Use A Serum?
Serums can be used in the morning or night. Different formulations are suited to different applications. Kiehl’s Daily Reviving Concentrate is a light blend of natural ingredients which nourishes the skin all day. Whereas the replenishing Midnight Recovery Concentrate is intended for night time use to restore and repair the skin. Exfoliant and Peel serums are also best suited for use at night when their active ingredients can penetrate the skin whilst you sleep.
