Is The Ordinary Retinol 0.5% in Squ... worth buying?

“The Ordinary Retinol 0.5% in Squalane is one of the cheapest ways to get a proper 0.5% retinol dose, with a refreshingly minimal formula that skips fragrance and alcohol entirely. The squalane base hydrates effectively, so most people find they can skip the extra moisturiser step and still maintain a comfortable routine.”

Pros

  • +Exceptional value for money — one of the most affordable 0.5% retinol serums on the market
  • +Extremely minimal, clean INCI — no fragrance, no alcohol, no unnecessary fillers or sensitisers
  • +Squalane base provides meaningful moisture occlusion; many users skip separate moisturiser entirely
  • +Effective for hyperpigmentation, post-acne scarring, and overall skin texture with consistent use
  • +30ml bottle lasts 3+ months with typical nightly use — good cost-per-use ratio

Cons

  • -0.5% is an intermediate strength — not appropriate for retinol beginners; 0.2% recommended first
  • -Oily, greasy texture from squalane base is poorly tolerated by oily and acne-prone skin types
  • -Retinol burn risk at skin folds (neck, eye corners) if too much product pools during sleep
  • -Anti-aging results for fine lines require 3–6 months of consistent use — slow payoff

Best For

intermediate retinol users stepping up from 0.2% dry and normal skin types anti-aging and fine line prevention hyperpigmentation and post-acne scarring minimalist skincare routines

Watch Out

  • !retinol beginners — strong risk of irritation at 0.5%; start with 0.2% for several weeks first
  • !oily and acne-prone skin — squalane base may worsen congestion, blackheads, and sebaceous filaments
  • !mandatory daily SPF use — retinol significantly increases UV sensitivity
  • !avoid applying on damp skin or into skin folds where pooling increases burn risk
  • !store in a cool, dark place — retinol degrades with light and heat exposure

What are the pros and cons of The Ordinary Retinol 0.5% in Squalane, Intermediate Retinol Serum for the Face That Is Anti-Aging and Skin Smoothing, 30ml?
Pros: Exceptional value for money — one of the most affordable 0.5% retinol serums on the market. Extremely minimal, clean INCI — no fragrance, no alcohol, no unnecessary fillers or sensitisers. Squalane base provides meaningful moisture occlusion; many users skip separate moisturiser entirely. Cons: 0.5% is an intermediate strength — not appropriate for retinol beginners; 0.2% recommended first. Oily, greasy texture from squalane base is poorly tolerated by oily and acne-prone skin types. Retinol burn risk at skin folds (neck, eye corners) if too much product pools during sleep.

What the Data Says About Retinol & Retinoids

Retinol vs retinaldehyde: which actually scores higher?

Retinaldehyde leads by 17.2 points on effectiveness. Across 42 retinol/retinoid products we scored, the 3 retinaldehyde products average 78.3 on effectiveness versus 61.1 for 31 retinol products.

The retinaldehyde products in our database:

  • Naturium Retinaldehyde Cream Serum 0.05% — 80 effectiveness, 83 overall
  • Paula's Choice CLINICAL Pro Retinaldehyde — 74 effectiveness, 64 overall
  • Medik8 Crystal Retinal 3 — 81 effectiveness, 79 overall (uses retinaldehyde despite the name)

All three beat the retinol average on effectiveness. The biological reason: retinaldehyde sits one conversion step closer to retinoic acid, the form your skin actually uses. Retinol requires two conversions; retinaldehyde requires one.

The honest caveat: 3 products is a small sample. The gap is wide enough to take seriously, but we'd want more retinaldehyde products on the market before calling it definitive. For now, the data favours retinaldehyde — but your options are limited.

Why do most retinol products score below average?

31 retinol products average 61.1 on effectiveness. Most land in mediocre territory. The molecule works — but the average product doesn't deliver it well.

The top retinol performers prove it can be done right:

  • Paula's Choice CLINICAL 1% Retinol — 82 effectiveness, 76 overall
  • Indeed Labs Retinol Reface — 80 effectiveness, 75 overall
  • The Ordinary Retinol 0.5% in Squalane — 75 effectiveness, 74 overall

Three factors separate winners from the rest:

  1. Concentration. Products with clearly stated, meaningful percentages (0.5%–1%) score higher. Many products list retinol without disclosing how much.
  2. Stability. Retinol degrades with light and air exposure. Good packaging (airless pumps, opaque tubes) and encapsulation technology keep the molecule intact.
  3. Supporting ingredients. Top scorers pair retinol with stabilisers, squalane, or delivery systems that protect it until it reaches your skin.

The average retinol product fails on one or more of these. A retinol label doesn't guarantee results — the formulation behind it determines whether you're getting active retinol or degraded filler.
