How to Use Retinol: Benefits, Application, and Best Practices

Retinol has earned its place as a modern skincare essential. Celebrated for its ability to smooth fine lines, refine uneven texture, and reduce the appearance of blemishes, it remains one of the most effective ingredients for achieving youthful, healthy-looking skin. Yet with so much advice available, often contradictory, getting started can feel confusing.

If you are wondering how to apply retinol correctly or want to avoid common missteps, consider this your straightforward and science-driven guide. Whether you are new to retinol or refining your routine, you will learn how retinol works, how often to use it, and how to maximise visible results. Plus, we’ll introduce some of Perricone MD’s expertly formulated products, like our High Potency Triple Retinol Renewal Serum, which makes incorporating retinol easy and effective. 

What is Retinol and How Does It Work?

Retinol is a derivative of vitamin A. It is a powerful chemical exfoliating ingredient that encourages the quicker removal of dead skin cells from the surface for optimal skin renewal. It supports the natural cell-turnover process that keeps skin looking fresh, smooth, and healthy. With consistent use this process helps improve texture, unclog pores, and enhance radiance. 

That’s just the beginning, retinol also boosts the look of collagen, working hard to maintain the appearance of firm, plump and youthful skin. Collagen provides structure and elastin keeps skin supple. With time, regular retinol use visibly reduces fine lines, wrinkles and enlarged pores. 

Why is Retinol So Effective?

• Smooths Skin Texture: Accelerates the shedding of dead skin cells for an optimally renewed and more refined complexion. 
• Unclogs Pores: Helps prevent breakouts by keeping pores clear of the feeling of excess oil and debris. 
• Boosts Collagen Production: Improves the appearance of elasticity while reducing the look of fine lines and wrinkles.
• Fades Dark Spots: Minimises the appearance of hyperpigmentation caused by environmental stressors or blemishes.

For those seeking visible results without unnecessary irritation, our Triple Retinol Renewal Collection combines three distinct types of retinols for a gradual yet powerful effect. This makes it suitable for most skin types. 

When To Start Using Retinol?

The ideal time to introduce retinol depends on your personal skin goals. Many experts recommend beginning in your mid-to-late 20s when collagen production naturally begins to slow. However, if you are experiencing blemishes, uneven texture or uneven pigmentation earlier, retinol can help address the appearance of these concerns before they progress.

When to Start Based on Your Skin Goals:

• In Your 20s: Preserve the look of naturally collagen-rich skin, maintain brightness and prevent early signs of ageing.
• In Your 30s: Target fine lines and support improved elasticity.
• In Your 40s and Beyond: Focus on enhancing firmness, reducing the appearance of wrinkles and restoring a smoother and more radiant complexion.

If you are new to retinol, start with a lower concentration and gradually increase strength as your skin builds tolerance. Perricone MD offers a range of retinol products to suit every stage of your skincare journey. 

How to Use Retinol Correctly

Using retinol properly is essential for maximising benefits while minimising potential irritation. A slow and steady introduction allows your skin to adjust comfortably and build a tolerance.

Step-by-Step Retinol Application Guide:

1. Cleanse Your Skin: Use a gentle, non-stripping cleanser to remove impurities without disrupting the skin barrier.
2. Apply Retinol: Use a pea-sized amount and smooth it evenly across the face, avoiding the eyes, nostrils and mouth. Apply in upward motions across the face and neck.
3. Wait and Moisturise: Allow the formula to absorb for 5 to 10 minutes. Then follow with a hydrating moisturiser to soothe and nourish the skin.
4. Use Sunscreen Daily: Retinol increases UV sensitivity. An SPF 30 or higher every morning is essential for preventing sunburn, hyperpigmentation and premature ageing

For the delicate eye area, our Triple Retinol Renewal Eye Serum targets fine lines, wrinkles and crow’s feet with a formula gentle enough for daily use. 

How Often Should You Use Retinol?

Building a retinol routine is a gradual process. Giving your skin time to adapt ensures long-term success without unnecessary irritation. 

Beginner’s Schedule for Retinol:

• Week 1 to 2: Use 1 to 2 times per week on non-consecutive days.
• Week 3 to 4: Increase to 3 times per week if well tolerated.
• Week 5 and Beyond: Progress to every other night or nightly, depending on your skin’s response.

If redness, peeling or irritation occurs, scale back and incorporate a soothing, hydrating product such as our Hypoallergenic Moisturiser to help restore balance.

Retinol vs. Retinoids: What’s the Difference?

The terms are often used interchangeably but they are not identical. Retinol is a type of retinoid that is available over the counter. It converts to retinoic acid in the skin, which makes it gentler. Prescription-strength retinoids, such as tretinoin, act faster but may cause more irritation.

Key Differences between Retinol and Retinoids:

• Retinol: Available over the counter, converts to retinoic acid, gentler on skin.
• Retinoids: Prescription strength, faster results, higher potential for irritation.

Perricone MD’s Triple Retinol Renewal Serum blends encapsulated retinol, retinol ester and phyto-retinol to visibly reduce lines and wrinkles while accelerating surface exfoliation and renewal for the look of collagen-rich skin. 

Common Side Effects and How to Minimise Them

Mild redness, dryness and flaking are common when starting retinol. This adjustment period, often called the ‘retinol purge’, is temporary as your skin adapts.

How to Reduce Irritation:

• Start with a low concentration and increase gradually. 
• Use a hydrating, fragrance-free moisturiser to support the skin barrier.
• Avoid other exfoliating acids such as AHAs and BHAs on the same nights as retinol. 

To calm discomfort and replenish moisture, apply Cold Plasma Plus+ Advanced Hydrating Complex after retinol. 

How Long Does It Take for Retinol to Work?

Retinol rewards consistency. While you may notice smoother texture and subtle radiance within 4 to 6 weeks, more visible improvements typically take longer.

What to Expect Over Time when Using Retinol:

• 4-6 weeks: Smoother skin texture and fewer blemishes.
• 8-12 weeks: More even tone and a visible reduction in fine lines.
• 3-6 months: Firmer, collagen-rich-looking skin and long-term radiance.

With consistent use, retinol gradually transforms the complexion.

What Not to Use with Retinol

Retinol is powerful, so pairing it with the wrong ingredients can lead to irritation or reduced effectiveness.

Ingredients to Avoid When Using Retinol:

• AHAs and BHAs: Can cause over-exfoliation and sensitivity.
• Benzoyl Peroxide: May deactivate retinol and reduce its effectiveness.
• Vitamin C: Best used separately. Apply vitamin C in the morning and retinol at night.

A simple and hydrating routine is the best companion to retinol.

Perfect Pairs: Ingredients That Work Well with Retinol

Retinol performs best when paired with ingredients that hydrate, soothe and protect.

Best Ingredients to Pair with Retinol:

• Hyaluronic Acid: Provides lasting hydration for plump and comfortable skin.
• Niacinamide: Strengthens the skin barrier and soothes visible redness.
• CoQ10: Supports antioxidant protection. 

For optimal balance, pair our Triple Retinol Renewal Serum with High Potency Hyaluronic Intensive Hydrating Serum to help minimise dryness.
