How To Use And Layer Vitamin C Serum

In terms of multifunctional skincare products (and amazing results), vitamin C serums sit high up on the list. Especially in New Zealand, the antioxidative benefits of vitamin C skincare help to address one of the biggest motivators of skin stress – UV radiation.

How To Use And Layer Vitamin C Serum

As with any powerful skincare step, knowing how to use vitamin C serum correctly will bring about the most benefits. It’s also important to consider which other ingredients you layer with it, to ensure your routine is complimentary.

Ahead, we deep dive into some of your biggest vitamin C application questions, like ‘can I use vitamin c and niacinamide together?’, and ‘can I layer vitamin C with retinol?’. Perfect your skin-boosting routine with Kiehl’s range of vitamin C serums.

The benefits of vitamin C serum

When we said vitamin C serums are multifunctional, we really weren’t kidding. This skincare superhero can offer three main benefits to skin, which work in unison to retain a youthful tone and texture. Knowing how to apply vitamin C serum correctly can boost your skin in the following ways:

  1. Protection against skin oxidisation. A form of cellular stress, oxidisation occurs as a result of UV radiation – and accounts for a large proportion of visible skin ageing. When used in the lightweight format of a serum, vitamin C can address oxidisation in skin.

  2. Promotes collagen production. Collagen is skin’s natural way of maintaining skin structure, but it begins to decrease in production as we age. A vitamin C serum supports collagen in the skin, helping to retain firmness and bounce.

  3. Boosts radiance. All skin types can experience dulled skin – whether it be due to weather, dryness or skin stress. A Vitamin C serum absorbs into skin deeply, evening skin tone and promoting bright complexions.

How to layer vitamin C serum

When combined correctly, multi-step skincare routines can enhance, protect and lift skin’s appearance for the long term. Some super-powered ingredients get along better than others however – and there are some combinations that we recommend you don’t mix vitamin C with. See how to layer vitamin C with your other products below.

1. Can you use retinol and vitamin C together?

Retinol (or vitamin A) is a powerful addition to a range of routines, whether it be for anti-ageing benefits or to reduce acne-prone concerns. We recommend the use of both vitamin C and retinol in your skincare regime, as they both protect skin and promote skin health. However, as the two are potent, they should be applied apart. For how to use vitamin C serum and retinol, include retinol in your evening routine, and apply vitamin C in the morning. This gives skin extra protection from oxidisation in the day and helps to prevent skin sensitivity at night. Retinol Skin-Renewing Daily Micro-Dose Serum can be used in the evening for clear, fresher skin.

2. Can you layer vitamin C and niacinamide?

Otherwise known as vitamin B3, niacinamide is another skin tone-evening nutrient. Niacinamide can improve hydration, help to reduce the appearance of skin ageing signs like fine lines, reduce breakouts and the appearance of pores. With so many benefits, it’s great news that both niacinamide and vitamin C can be layered together. If looking to support acne-prone skin, niacinamide-infused Breakout Control Targeted Acne Spot Treatment can be implemented alongside your vitamin C serum. For how to layer vitamin c and niacinamide, we recommend following with a thick moisturiser to support skin comfort.

3. Can you use vitamin C with hyaluronic acid?

A super-hydrator, hyaluronic acid supports skin throughout the use of potent ingredients like vitamin C. Hyaluronic acid is gentle enough for universal use and promotes optimum levels of hydration in skin. Layering vitamin C with hyaluronic acid ensures skin is fully supported. We recommend applying a hyaluronic acid-infused cream on top of your vitamin C serum, or using a serum formula infused with both.
