'I'm a doctor - use one product morning and night for plump, hydrated skin'

Global skin doctor and cosmetic formulator at SkincarebyDrV Dr Vanita Rattan said it is good to use moisturiser in the morning and evening.

She told GB News: "Moisturiser is an essential part of your nighttime skin care routine because it helps lock in moisture, repair the skin barrier and support skin regeneration while you sleep.

"During the night, your skin undergoes a natural repair process, and a good moisturiser provides the necessary hydration to help this process.

"Moisturisers used during the day and night can differ in their formulations, especially if the nighttime moisturiser is targeted for treatment."

A good moisturiser is a staple in any routine, but look for different ingredients depending on what time of day you are applying it, the doctor explained.

She continued: "For example, if your moisturiser contains any form of vitamin A (retinol, retinaldehyde, retinoic acid, retinyl palmitate etc) it is essential to apply it only at night because vitamin A in skin care is a photosensitive ingredient.

"Exposure to sunlight can degrade its effectiveness and potentially cause skin irritation. Your morning moisturiser should contain UV-stable ingredients that protect and nourish the skin throughout the day.

"Ingredients like niacinamide and vitamin C are great choices as Niacinamide helps improve the skin’s barrier, while vitamin C provides antioxidant protection and brightens the skin."

There are also some important ingredients to look for in all your skin care products.

The expert suggested ceramides and peptides can help with skin's elasticity. This can help you maintain a youthful look.

Dr Rattan continued: "Both your AM and PM moisturisers should contain ceramides and peptides to help prevent moisture loss and maintain your skin's elasticity.

"As well as this, both moisturisers should ideally be in airless pumps to prevent exposure to air, which can reduce the effectiveness of certain ingredients, like antioxidants, retinol, and other sensitive compounds."

When applying skin care, the doctor suggested putting this on at least two hours before bed to avoid it from rubbing off.

She said: "The reason we should do our skin care routine two hours before bed is to allow enough time for all the active ingredients to penetrate the skin before going to sleep.

"Many of us sleep with our faces pressed against the pillow, so if you go to bed too soon after applying serums and creams, there's a higher chance that the products will transfer onto your pillow rather than being absorbed by your skin."
