Best Retinol Serums for Every Skin Type: Your Complete Guide

If you're looking to smooth fine lines, improve uneven skin tone or give your complexion a little extra glow, retinol could be the skincare ingredient you've been searching for.

A favourite among skincare professionals, retinol is a form of vitamin A known for improving the appearance of fine lines, uneven texture and pigmentation. But with so many different strengths, formulas and brands available, choosing the best retinol serum for your skin isn't always straightforward.

Whether you're completely new to vitamin A or ready to upgrade your skincare routine, we're here to make finding your perfect match that little bit easier.

At Millies, we believe great skincare starts with understanding your skin. That's why we've put together this guide to some of our favourite retinol serums, from gentle beginner-friendly formulas to more advanced treatments.

What Are the Best Retinol Serums?

The best retinol serum depends on your skin type, experience with retinoids and main skincare concerns. Beginners may prefer a gentle, slow-release formula, while experienced users may benefit from more targeted retinol or retinal treatments.

Here's our guide to choosing the right retinol serum for your skin.

3. Best Retinol Serum for Sensitive-Feeling Skin: La Roche-Posay Retinol B3 Serum

Best for: Those concerned about fine lines and uneven tone who want a formula that also includes vitamin B3.

Retinol can feel a little intimidating when your skin is easily irritated. That's where a carefully selected formula and a gradual introduction make all the difference.

La Roche-Posay Retinol B3 Serum pairs retinol with niacinamide, also known as vitamin B3, and hydrating ingredients.

The formula is designed to improve the appearance of wrinkles, uneven skin tone and dullness.

How to Choose the Right Retinol Strength

When it comes to retinol, stronger isn't always better.

The concentration that's right for you depends on your skin's tolerance, the formulation and whether you've used retinoids before.

These ranges aren't universal rules. Encapsulation, product formulation and the type of retinoid all affect performance. Retinal percentages should not be compared directly with retinol percentages.

If you're unsure which strength to choose, our Millies skincare team can help you find a suitable option.

How to Use Retinol in Your Skincare Routine

Retinol is generally best introduced gradually as part of your evening skincare routine, followed by moisturiser and daily sun protection.

Here's a simple routine to get started:

1. Cleanse: Wash your face with a gentle facial cleanser and pat the skin dry.

2. Apply retinol: Use the amount recommended on your chosen product.

3. Moisturise: Follow with a hydrating moisturiser to help support your skin barrier.

4. Protect your skin: Apply a broad-spectrum SPF 30 or higher every morning.

For beginners, introducing retinol once or twice a week is often a sensible starting point. Increase gradually according to product directions and skin tolerance.

Avoid applying retinol to broken or irritated skin. If you experience persistent burning, significant redness or peeling, discontinue use and seek professional advice.

Daily sun protection is particularly important when using retinoids. If you're unsure which formula to choose, discover our guide to finding the best SPF for your skin type.

Retinoids should be avoided during pregnancy and when planning pregnancy. If breastfeeding, ask your healthcare professional for individual guidance.

Retinol Serum FAQs

Which retinol serum is best for beginners?

The INKEY List Starter Retinol Serum and IMAGE Skincare Ageless+ Pure Liquid Retinol 0.1% are two options to consider. Both are designed for people beginning their retinoid skincare journey, although individual tolerability varies.

Which retinol serum is best for wrinkles?

Murad Retinol Youth Renewal Serum is a targeted option for fine lines, wrinkles and loss of firmness. The best choice will also depend on your skin type, previous retinoid use and tolerance.

Can I use retinol if I have sensitive skin?

Some people with sensitive skin can tolerate carefully selected retinoid formulas introduced slowly, but others may experience irritation. Start cautiously and seek professional advice if you have rosacea, eczema or a compromised skin barrier.

How often should I use retinol?

Many beginners start with one or two evenings per week before gradually increasing frequency. Always follow the specific product instructions and reduce use if irritation occurs.

Should I use retinol before or after moisturiser?

Retinol is commonly applied after cleansing and before moisturiser. For some sensitive skin types, using moisturiser first can help reduce irritation, although you should follow the directions for your chosen product.

For more guidance on layering your products, read our article explaining whether to apply serum or moisturiser first.

Can you use retinol every day?

Some people can eventually tolerate nightly retinol use. However, daily use isn't essential for everyone and shouldn't be the starting point for most beginners.

How long does retinol take to work?

Retinol works gradually. Visible improvements in texture may appear after several weeks, while fine lines and uneven pigmentation can take approximately 8–12 weeks or longer. Results depend on the formula, frequency of use and individual skin.

If you're wondering what to expect from other active ingredients too, discover how long it takes to see results from your skincare routine.

Yes, many people use both ingredients within the same skincare routine. A straightforward approach is to use vitamin C in the morning and retinol at night, while wearing sunscreen daily.

Is retinol suitable during pregnancy?

Retinoid skincare products should not be used during pregnancy or when planning pregnancy. Speak to your healthcare professional for advice about suitable skincare alternatives.
