Turning 40 is a landmark birthday for many women, as they come into their own as professionals, mothers, partners, and friends. It’s a time for celebrating self and fully embracing life.

Cell turnover slows down as we age, and by the time we’re in our 40s, it takes up to 40 days.

However, there’s no getting away from the fact that our skin starts showing visible signs of ageing from around this age, as collagen production slows, and our skin finds it harder to retain moisture.

But by introducing manageable changes into their daily beauty, eating, and exercise regime, clients can help their skin retain its youthful look for longer. “As we age, our skin cells take longer to regenerate, and this can result in a dull complexion,” said Mirjana Brlecic, founder of natural skincare range Nikel Cosmetics.

“Cell turnover is the constant shedding of dead skin cells and their replacement with younger cells. It’s a natural process that begins with the production of new skin cells at the lowest layer of the epidermis; these travel to the top layer, where they’re shed. Skin-cell turnover in babies takes just two weeks.”

“This slows down as we age, and by the time we’re in our 40s, it takes up to 40 days. A great way to help boost cell turnover is to include Vitamin C in your skincare regime. Vitamin C protects the skin from the effects of ageing and plays a vital role in collagen production and maintenance.”

“Damage from too much exposure to the sun and from free radicals also begins showing in our skin when we’re in our 40s, and the potent antioxidant action of vitamin C helps with these problems too.” Brlecic recommends products with plant-activated ingredients, particularly St John’s wort extract which is rich in vitamin C.

“The oil of this medicinal plant also strengthens skin elasticity, prevents infections, and soothes damage from eczema and sunburns, reducing skin flaking and dryness induced by dehydration. “Including fruits and vegetables high in vitamin C in your diet is another way to maximise the benefits of this potent vitamin. Kiwis, guavas, broccoli, and cauliflower are all high in vitamin C, while a cup of chopped red pepper contains nearly three times more vitamin C than an orange. Eat as many of these raw as possible.

“Hyaluronic acid, a substance produced naturally by the body, can hold up to a thousand times its weight in water,” said Brlecic. “It’s what makes our skin feel and look hydrated and healthy. The occurrence of this magnet for moisture within our skin starts to decrease when we’re in our 30s. Including a moisturiser in your skincare regime that contains hyaluronic acid will definitely help to make your skin look plump and glowing again.”

Exercise is another important element of skincare. “Getting moving increases blood flow in the body, nourishing and strengthening the skin’s cells, and carrying away waste products, including free radicals,” said Brlecic. “Twenty minutes of exercise – brisk walking is fine – three times a week is all you need to keep your muscles, joints, and skin healthy.”
