Retinol explained – everything you need to know before adding it to your skincare routine

Beauty Shelf with Emily Darlow

If you’ve spent any time browsing the skincare aisle recently, chances are you’ve noticed retinol popping up everywhere. From serums and creams to eye treatments and moisturisers, it’s become one of the most talked-about ingredients in skincare, and for good reason.

Retinol has long been considered the gold standard for addressing the visible signs of ageing. While it won’t erase wrinkles overnight, consistent use can help improve skin texture, soften fine lines, even out skin tone and restore some of the radiance that naturally diminishes as we get older.

So, what exactly is it?

Retinol is a derivative of vitamin A. Once applied to the skin, it’s converted into retinoic acid, the active form that encourages skin cells to renew more quickly. As we age, our natural skin cell turnover slows down, meaning dull skin cells linger on the surface for longer while collagen production also declines.

By speeding up cell turnover and stimulating collagen production, retinol helps reveal fresher skin underneath while supporting firmer, smoother-looking skin over time. It can also help fade age spots and sun damage, improve uneven texture and minimise the appearance of enlarged pores.

The key word, however, is time.

Unlike some skincare ingredients that offer immediate hydration or plumping, retinol works gradually. Most people begin noticing improvements after around eight to 12 weeks of regular use, with continued improvements over several months.

If you’re using retinol for the first time, it’s best to introduce it slowly. Start by applying it just two or three nights a week before gradually increasing frequency if your skin tolerates it well. Mild dryness, flaking or redness during the adjustment period is common, particularly with stronger formulations.

Because retinol encourages faster skin renewal, it also makes skin more sensitive to ultraviolet (UV) rays. That’s why dermatologists recommend applying retinol at night and wearing a broad-spectrum SPF30 or higher sunscreen every morning to help protect your skin and preserve your results.

It’s also worth checking with your doctor or pharmacist before introducing retinol if you’re using prescription retinoids or other active skincare ingredients, as combining certain products can increase irritation. If you have particularly sensitive skin or an existing skin condition, professional advice can help you choose the most suitable product.

Whether you’re just starting out or looking to upgrade your routine, here are a few products worth considering.

No7 Pure Retinol 1% Concentrate
Price: $69.99

Designed for experienced retinol users, this concentrated serum contains 1% pure retinol to target fine lines, wrinkles and uneven skin texture. Its lightweight formula absorbs quickly and is intended to help improve skin firmness and radiance with ongoing use. Because it is a relatively high-strength retinol, it’s best introduced gradually and used at night.

Elizabeth Arden Retinol + HPR Ceramide Rapid Skin Renewing Eye Cream
Price: $125

The delicate eye area is often where signs of ageing first appear. This eye cream combines traditional retinol with HPR (Hydroxypinacolone Retinoate), a newer-generation retinoid that is designed to deliver retinoid benefits while being gentler on the skin. Ceramides help strengthen the skin’s natural barrier and lock in moisture, helping to minimise the dryness that retinol can sometimes cause. The result is smoother-looking skin and a reduction in the appearance of crow’s feet and fine lines.

Elizabeth Arden Retinol + HPR Ceramide Capsules Rapid Skin Renewing Serum
Price: $90

These single-dose capsules combine retinol, HPR and ceramides in a fragrance-free serum designed to improve skin texture, firmness and brightness. The capsules help keep the ingredients fresh while delivering the right amount for each application. The addition of ceramides supports hydration and helps reinforce the skin barrier, making the formula suitable for those wanting the benefits of retinoids with added nourishment.

RoC Derm Correxion Firming Serum Stick
Price: $59.99

Rather than a traditional serum, this innovative stick allows you to target areas that have begun to lose firmness, including the face, neck and jawline. It combines RoC’s retinol technology with ingredients that support skin elasticity in an easy-to-apply solid serum format, making it ideal for touch-ups or travel while helping improve the appearance of sagging skin over time.

La Roche-Posay Retinol B3 Serum
Price: $75.99
Buy it here

A favourite among those with sensitive skin, this serum combines pure retinol with vitamin B3 (niacinamide). While the retinol works to smooth wrinkles and refine skin texture, niacinamide helps calm the skin and strengthen its protective barrier, reducing the likelihood of irritation. It’s an excellent option for anyone looking to begin using retinol without jumping straight into a higher-strength product.

Nivea Men Active Age Moisturising Cream SPF15
Price: $23
Buy it here

Designed specifically for men’s skin, this daily moisturiser contains Pro-Retinol, a vitamin A derivative that offers anti-ageing benefits in a gentler formulation than pure retinol. It helps reduce the appearance of fine lines while providing all-day hydration, and the addition of SPF15 offers everyday sun protection. While SPF15 provides some defence against UV rays, anyone using stronger retinol products at night should still apply a dedicated broad-spectrum SPF30 or SPF50 sunscreen each morning for optimal protection.

Retinol has earned its reputation as one of skincare’s most effective ingredients. While it requires patience and consistency, the long-term benefits can be significant, particularly for mature skin. Start slowly, moisturise well, wear sunscreen every day and give your skin time to respond. With the right product and a little persistence, retinol can become one of the hardest-working steps in your skincare routine.
