Likewise, benzoyl peroxide and retinol is a combination best avoided. “Benzoyl peroxide oxidises retinol, meaning it cancels out the retinol’s benefits to the skin. But as well as that, it can be irritating to the skin if they’re applied together,” adds Lucy. If a product is tingly but tolerable and effective, combine it with gentle next steps, like a nourishing vitamin E moisturiser.

Tip 9 – Leave 30 seconds between applying products

The only way we could be more guilty of this is if you caught us red-handed in the cookie jar. In a world where we get home from work and rush to the gym or sofa depending on your personality, leaving time between your skincare steps (even as little as 30 seconds) can quickly be forgotten.

“Allowing products to settle between steps helps with absorption and prevents pilling. In most cases, 30-60 seconds is enough, but if your skin still feels tacky, wait until it’s slightly drier before layering the next product,” advises Dr Patel. “For active ingredients like retinoids, waiting a little longer can improve effectiveness and reduce the risk of irritation. For sunscreen, allow this to set for at least two minutes before makeup, so it forms an even, protective film.”

Tip 10 – Apply these products to damp skin

Which is better for applying skincare products, dry skin or damp skin? The answer is both – depending on the product you’re using. “Applying certain skincare products to slightly damp skin can boost absorption and help lock in moisture. Damp skin is more permeable, allowing hydrating ingredients like hyaluronic acid to draw in and retain more water. Make sure your skin is only lightly damp, not dripping,” says Dr Patel.

But this rule doesn’t apply for all products, with Dr Patel revealing that oil-based formulas are best applied on dry skin, as they can separate and absorb less effectively on damp skin. “Retinol or acids are best applied to dry skin as well, to reduce irritation and ensure controlled absorption,” he says.

If in doubt, remember Dr Patel’s golden nugget. “In general, serums and lightweight moisturisers can be applied to damp skin, while potent actives should always go on dry skin.”

How should we structure our daytime skincare regime?

During the day, your beauty regime should focus on protecting your skin from UV rays and environmental aggressors, such as dust and pollution. “At Medik8 we like to keep it super simple,” says Daniel. “Vitamin C and sunscreen by day, and retinol by night. Then, additional products and active ingredients can be added to treat specific skin types and concerns.”

An example of a good morning routine:

1. Cleanse

Cleansing in the morning is an important step to refresh your skin and prepare it for the day ahead. It also creates a clean canvas that helps your serums, moisturiser and sunscreen absorb more effectively.

“Cleansing is the first step of any good skincare routine,” says Lucy. “Cleanse each morning with a cream or oil based cleanser to remove any dead skin, oils or sweat that may have built up overnight.”

2. Tone (optional)

Toners are an optional step, but we personally always tone – as does our expert Lucy. “Toners balance the skin’s pH, hydrate, and remove any remaining product from the skin,” she says. Toners can also offer up some exfoliating benefits. “If you want to incorporate acids into your skincare, a toner containing them is a great way to start. I would recommend a lactic acid or a mild glycolic. However, if you plan to use a retinol at night, I’d skip using acid toners and go for a balancing or calming toner instead.”

3. Vitamin C

Vitamin C is an absolute skin superfood due to its powerful antioxidant properties and ability to brighten and even skin tone. It also helps to provide an extra layer of protection (in addition to your SPF) against sun exposure and pollution, while stimulating collagen production for firmer, plumper skin. If you use a vitamin C serum regularly, it can fade dark spots, reduce dullness and promote a healthy, radiant glow.

4. Active ingredient (optional)

You can apply another serum over your vitamin C if you want to, and the ingredient Dr Patel recommends looking for is growth factors. “In my opinion, growth factors are the single most powerful and impactful ingredient you need in your routine. They can reverse signs of ageing and repair damage by triggering the process for essential cell repair,” he reveals.
