When it comes to anti-aging skincare, few ingredients are as well-researched and effective as retinol. The Ordinary, a brand known for its science-backed, affordable formulations, offers one of the most cost-effective retinol serums on the market: The Ordinary Retinol 0.5% in Squalane.
After weeks of testing and comparing it to higher-end alternatives, I can confidently say that this budget-friendly option delivers impressive results—if you know how to use it correctly. Below, I’ll break down everything you need to know, from its key benefits to potential drawbacks and who should (or shouldn’t) use it.
Why We Recommend The Ordinary Retinol 0.5% in Squalane
1. High-Quality Retinol at a Fraction of the Price
Most dermatologist-recommended retinol serums cost upwards of $50, but The Ordinary’s version comes in at under $15 for a 30ml bottle. Despite the low price, it doesn’t cut corners—this formula contains 0.5% pure retinol, a concentration that’s strong enough to deliver visible anti-aging benefits without being overly harsh for most users (once tolerance is built)28.
2. Stable, Water-Free Formula for Maximum Potency
Retinol is notoriously unstable when exposed to water, light, or air. The Ordinary avoids this issue by formulating this serum in anhydrous (water-free) squalane oil, which helps preserve the retinol’s efficacy over time2. Squalane, a lightweight emollient derived from plants, also provides hydration, making this a great option for dry or combination skin types.
3. Gradual Strength Options for Building Tolerance
If you’re new to retinol, The Ordinary offers a step-up system with three concentrations:
0.2% Retinol in Squalane (for beginners)
0.5% Retinol in Squalane (intermediate)
1% Retinol in Squalane (advanced)
This makes it easy to start low and gradually increase strength as your skin adapts, minimizing irritation8.
4. Targets Multiple Skin Concerns
Retinol is a multitasker, and this serum helps with:
Fine lines & wrinkles (by boosting collagen production)
Uneven skin tone & hyperpigmentation (by accelerating cell turnover)
Acne & clogged pores (by regulating sebum production)10
Potential Downsides to Consider
1. Can Cause Initial Irritation (Redness, Peeling, Sensitivity)
As with any retinol product, this serum can cause dryness, redness, and flaking—especially in the first few weeks of use. The Ordinary explicitly warns that new users may experience temporary purging (breakouts) as the skin adjusts2.
How to mitigate this:
Start by applying it 2-3 times per week, gradually increasing frequency.
Always follow with a rich moisturizer to combat dryness.
Avoid combining it with other exfoliating acids (like AHAs/BHAs) to prevent over-exfoliation10.
2. Oily Texture May Not Suit Everyone
Since this formula is suspended in squalane oil, it has a slightly greasy feel that may not appeal to those with oily skin. However, the oil absorbs within a few minutes and doesn’t leave a heavy residue.
3. Strictly Night-Use Only + Must Wear Sunscreen
Retinol increases photosensitivity, meaning your skin becomes more prone to sun damage. This product must be used at night, and daily sunscreen is non-negotiable the next morning38.
Who Should (and Shouldn’t) Use This Product?
Best For:
✔ Beginners to retinol (after starting with 0.2%)
✔ Those with dry or combination skin (thanks to squalane’s hydrating properties)
✔ Budget-conscious shoppers who want clinical-grade anti-aging without luxury prices
Not Recommended For:
✖ Extremely sensitive or reactive skin (consider The Ordinary’s gentler Granactive Retinoid 2% instead)6
✖ Pregnant or breastfeeding individuals (retinol is not considered safe during pregnancy)
✖ Those who skip sunscreen (retinol + sun exposure = bad news)
How to Use The Ordinary Retinol 0.5% in Squalane for Best Results
Start slow: Apply 2-3 nights per week for the first 2 weeks.
Apply to dry skin: After cleansing and toning, but before heavier creams.
Use only a few drops: A little goes a long way—overuse increases irritation risk.
Follow with moisturizer: Lock in hydration with a barrier-repairing cream.
Always wear SPF 30+ the next day: Non-negotiable for preventing sun damage.
Final Verdict: Is It Worth Buying?
If you’re looking for a budget-friendly, effective retinol serum and are willing to endure a short adjustment period, The Ordinary Retinol 0.5% in Squalane is an excellent choice. It’s not the most luxurious-feeling product, and the oily texture may not suit everyone, but the results speak for themselves.
For under $15, you’re getting a dermatologist-approved anti-aging powerhouse—just be patient, follow the instructions, and don’t skip sunscreen!
