What the gurus are saying

The packaging and potency create real friction here. The open-air dropper bottle lets heat and light degrade retinol quickly, which matters most in warm climates or without constant refrigeration. The 0.5% concentration sits awkwardly in the middle: strong enough to irritate beginners, yet now restricted to 0.3% maximum in the EU and UK, so reformulation is coming. Those new to retinol or with sensitive skin may find it irritating without easing in gradually (start a few times a week, not daily), while people already using tretinoin or those with oily skin tolerate it better. The squalane base does cushion irritation, but gurus split on whether the formulation itself feels greasy and whether that much retinol delivers real benefit at all, and the product has since been discontinued in favor of the brand's retinol emulsion.

"What lets it down is the packaging. [...] Heat accelerates retinol degradation significantly, and being in a warm climate like India isn't really going to be suitable for this, and most of us don't have time to keep it in [...] the fridge. [...] So for India, I think this product is just a no. I love The Ordinary for so many other products, but this isn't going to be one of them. This one unfortunately gets a three out of 10."

"The downside here is the packaging. It is nave safe. You know, even looks very similar, comes out the blends the same into the skin. However, this is 0.5%. So, this actually would now not be allowed in the UK and EU. 0.3% is going to be the max. So, they are going to have to reformulate this product. Again, not in Ella's palm. We just don't know how effective it is. So, for me, it's a no for skin of color."

"I just think the whole collection of the ordinary retinols is doomed. The formulations are greasy, they're not great, and of course we've now had the European Union retinol ban. [...] That ban restricts the use of retinol in over-the-counter products to 0.3%, and 0.3% retinol is going to do next to nothing unless you're a beginner or have super sensitive skin."

"Retinol is getting far too confusing, it's far too hard to formulate with, and consumers increasingly are not really wanting it as part of their skincare routine. This is why The Ordinary Retinol 0.5% in Squalane no longer exists. It was discontinued and was replaced by their retinol emulsion, which is now one of the brand's best sellers."

"The Ordinary Retinol 0.5% in Squalane uses a moderate concentration of retinol to improve skin texture, reduce the appearance of fine lines, and boost collagen production. The addition of squalane will help hydrate and soothe, reducing the potential for irritation. The key ingredient is of course retinol 0.5%, which helps accelerate skin cell turnover, enhancing skin texture and reducing signs of aging."

"This can be a little bit more irritating than the 0.2%. If you've got oily skin, you might use the 0.5% rather than 0.2% because it won't irritate you as much. But if you've got irritated skin or a compromised skin barrier, repair that first and then start on 0.2%. If you've gone up the ladder, this is a great thing, but still be careful. Don't just start using this every day. Start using it alternately or even three days a week, and then week on week increase."

Adapalene vs Tretinoin - Which Is The Best ANTI-ACNE and ANTI-AGING Ingredient?
"The Ordinary has retinol and squalane. Remember, retinol is the most basic thing that you can get and you don't need a prescription for it, but it's really not that potent and it needs to oxidize twice to become the active form. This is a zero point five percent and they also have a one percent, and you can kind of graduate up if that's something that you're looking for."

What the evidence says.

Independent of what the gurus think, this is what the published research supports about the main active ingredients here.

Retinoids

Retinoids are among the best studied ingredients in dermatology, with solid evidence for acne and for the fine lines and rough texture that come from sun exposure. Dryness and flaking in the first few weeks are common and usually settle.

Humectants and emollients

Ingredients like these draw water into the surface layers and slow how fast it leaves. The evidence is for comfort, softness and hydration rather than for changing the structure of the skin.
