– A Buyer’s Guide

by: Lisa Hooper 29 Mar 2024

Dive into the world of Retinol, a game-changing ingredient in skincare, with us, Habitual Skin.

We're here to guide you through understanding this powerful component, known scientifically as a form of vitamin A, which plays a key role in renewing skin cells and enhancing elasticity. Retinol is our go-to because it transforms the skin, promoting a younger-looking, radiant complexion. But remember, it's strong stuff! That’s why we, at Habitual Skin, carefully select serums that marry Retinol with soothing, moisturising elements to ensure your skin is treated with love and care.

What is Retinol?

Retinol is a superstar in the skincare universe for a good reason: it works wonders in rejuvenating your skin, tackling everything from fine lines to acne. But, it's not just about using any Retinol product; it’s about finding the right one. That's where Habitual Skin steps in. We're your trusted ally, committed to finding formulations that are not only effective but also gentle on your skin. We believe in the power of pure, result-driven skincare, and we've applied this belief to our own products while also evaluating others in the market to give you the best advice.

Benefits of Retinol Serum

  • Reduces wrinkles and fine lines.
  • Improves skin texture.
  • Treats acne and reduces breakouts.
  • Fades age spots and hyperpigmentation.
  • Enhances skin elasticity.
  • Boosts skin hydration.

Why It's Crucial for Retinol Serums to Include Moisturising Ingredients

In Retinol formulations, ingredients like Hyaluronic Acid and Ceramides are vital. They combat Retinol-associated dryness, maintaining skin health and enhancing the serum’s effectiveness, making it a staple for all skin types.

Retinol has long been a staple in skincare routines. With countless options available, it's challenging to find the right one. That's why we've gathered the top Retinol Serums in the market, focusing on quality and results. Keep reading to find out our top 5 picks that you should buy.

What Should I Look For?

Navigating the vast sea of skincare choices can be overwhelming. We get it! At Habitual Skin, we've done the heavy lifting for you. We're here to help you decode the world of Retinol serums, making it easy and understandable. Here’s what to keep an eye out for:

Ingredients Matter

We stress the importance of genuine, active ingredients. It's not just about having Retinol listed somewhere on the bottle; it's about ensuring it's potent enough to make a real difference to your skin, without overwhelming it.

Strength and Sensitivity

Finding the right balance is key. Our Habitual Skin selection focuses on the perfect strength that delivers results while respecting your skin's natural balance.

Natural and Nurturing

We lean towards products made from the heart, with natural and safe ingredients, steering clear of harsh chemicals and unnecessary synthetics.

Dermatologist Tested

Products recommended or approved by dermatologists guarantee safety and effectiveness, providing assurance that these products are beneficial for the skin.

Money-back Guarantee

Ensure that the product you buy comes with a clear money-back guarantee on all purchases. It takes 1-3 months to see tangible results with new skincare products, so select a brand that allows you enough time to test & see if this product is best for your skincare needs.

What to Watch Out For in Retinol Serums

Prioritise Potency Over Quantity:

When choosing a Retinol serum, a lean ingredient list can often be more effective than one overflowing with fillers. Excessive ingredients can dilute the Retinol's strength, undermining the serum's ability to address your skin concerns effectively.

Avoid Fillers and Unnecessary Additives:

Beware of products laden with fillers and bulking agents. These components may diminish the effectiveness of Retinol and other active ingredients, impacting the health and appearance of your skin.

Choose Cruelty-Free Products:

Ethical considerations are paramount. Opt for Retinol serums not tested on animals to align with cruelty-free practices, contributing positively to the industry's humane standards.

Steer Clear of Fragrances:

Fragrances, though aesthetically pleasing, can lead to skin irritation or allergic reactions, especially in sensitive skin types. Opt for fragrance-free serums to focus solely on the benefits of Retinol without unnecessary side effects.

Value Over Price:

Higher price tags do not necessarily equate to higher quality. Assess whether a product's cost is justified by its formulation, effectiveness, and packaging, avoiding those that are expensive due to branding or marketing rather than substantive content.

2.  Medik8

by Medik8


Overall Grade


  • Enhanced retinol with climbazole
  • Three strength levels for customised use
  • Uses Time Release technology
  • Squalane and vitamin E for moisture without heaviness
  • UK-made


  • High retinol concentration may irritate sensitive skin
  • Requires additional skincare products for hydration
  • Returns only accepted for half-full products within 30 days of purchase

The Bottom Line

Medik8 Intelligent Retinol 10TR stands out as one of the top-tier choices for those pursuing an effective anti-ageing solution. Its formulation is a careful blend of potent retinol and climbazole, ensuring maximum age-defying benefits. With the flexibility of three strengths, it allows users to tailor their regimens. The incorporation of Time Release technology and ingredients like squalane and vitamin E addresses the common issue of skin irritation.

However, despite its many benefits, Medik8 Intelligent Retinol 10TR may present challenges for certain users. Its lack of traditional hydrating ingredients like Hyaluronic Acid and Ceramides means that it might not provide enough hydration for some, potentially requiring additional moisturising products in one’s skincare routine. Additionally, the high retinol concentration calls for caution for those with sensitive skin. Prospective users should consider starting with a lower concentration and gradually building up to higher levels to allow their skin to adjust. It's important to note that the return policy is somewhat restrictive, accepting only half-full products within 30 days of purchase, which might deter some potential buyers who prefer more flexible return options.

3. Trinny London

by Trinny London


Overall Grade


  • Combines retinal+ and granactive retinoid® 
  • Vitamin F for nourishing and protecting the skin barrier
  • Bacillus ferment for lifting and firming
  • Cruelty-free and vegan formula
  • Suitable for all skin types
  • Refillable packaging


  • Pricier than other retinol options
  • High retinal content results in a yellow tint, which may stain fabrics
  • The distinctive smell might not be appealing to all users
  • High retinol concentration may irritate sensitive skin
  • Returns accepted within 30 days of purchase
  • Italy-made

The Bottom Line

Trinny London’s Retinal+ Serum Overnight Sensation represents cutting-edge retinoid treatment, combining retinal+ with granactive retinoid® for groundbreaking results. This serum promises to re-energise and firm up skin, diminishing wrinkles and fine lines without the peeling often associated with retinol treatments. Its formulation is a combination of advanced science and skincare, offering visible improvements in skin texture and youthfulness.

However, the serum's unique formula comes with a few caveats. Its high retinal content gives the product a yellow hue, potentially leading to staining, and its distinct aroma might not suit everyone's preferences. Additionally, the product lacks moisturising ingredients like Hyaluronic Acid or Ceramides, which might be a drawback for those seeking extra hydration. The relatively high cost and return policy condition of 30 days could also be limiting factors for some customers. Despite these drawbacks, for those seeking intensive treatment to revive their skin, this serum presents a compelling option, though its suitability for sensitive skin should be carefully considered.

Learn More


  • 1% pure retinol
  • Free from additives and parabens
  • Suitable for combination, dry, and normal skin
  • Free samples with purchase


  • Unverified claims of reducing breakouts
  • Non-encapsulated retinol
  • Challenge in distinguishing counterfeits
  • Not suitable for dehydrated or sensitive skin
  • High-cost and US-made

The Bottom Line

SkinCeuticals Retinol 1.0 is formulated for normal, oily, and combination skin types. It incorporates soothing agents derived from chamomile, enhancing skin comfort. Despite these benefits, the product may not be the best fit for those with dry or dehydrated skin, who might require additional hydration solutions. In addition, it does not include moisturising ingredients such as hyaluronic acid or ceramides, which are beneficial for hydration and skin barrier support.

The product positions itself effectively against breakouts, presumably due to the inclusion of Alcohol Denat. While this ingredient may assist in managing breakouts, its elevated presence could lead to skin irritation, particularly for those with more sensitive skin types. 

A challenge for consumers is the prevalence of counterfeit SkinCeuticals products, which raises concerns about product integrity and effectiveness. The company advises purchasing from authorised retailers, yet the difficulty in distinguishing authentic products can be daunting for buyers seeking assurance in their investment.

SkinCeuticals Retinol 1.0 is formulated without parabens and additives and uses non-encapsulated retinol. This choice may render the retinol gentler on the skin, but potentially less penetrative compared to encapsulated forms. Available in 0.3 and 0.5 concentrations, the product caters to various user experience levels but excludes those with dry or sensitive skin, a consideration for potential buyers.

5. Murad

by Murad


Overall Grade


  • Uses Retinol Tri-Active Technology
  • Fast-acting serum, clinically proven results
  • Hyaluronic Acid included for hydration and reducing dryness
  • Contains Swertia Flower Extract for enhanced skin resilience 
  • Suitable for all skin types


  • Pricier than other retinol options
  • Returns accepted within 30 days of purchase
  • May cause dryness or flaking in some users
  • Potentially too drying for certain sensitive skin types
  • US-made

The Bottom Line

Murad Retinol Youth Renewal Serum is a standout product for those seeking rapid yet gentle anti-ageing results. Its Retinol Tri-Active Technology minimises lines and wrinkles while remaining gentle to the skin. This serum is a testament to Murad's innovative approach, combining a fast-acting retinoid, delayed-release retinol, and a retinol booster to deliver impressive results. The addition of Swertia Flower Extract and moisturising Hyaluronic Acid enhances the serum's ability to improve skin resilience and provide essential hydration.

However, its premium price tag might be a deterrent for some. Additionally, despite being marketed as suitable for dry skin, there are indications that it might still lead to dryness or flaking for some users. The 30-day return policy, may not be sufficient for all users to fully assess the product's compatibility with their skin. In conclusion, Murad Retinol Youth Renewal Serum offers an advanced solution for tackling signs of ageing, though potential buyers should weigh its cost against their specific skin needs and sensitivities.
