When a brand shares the retinol percentage, you can compare products and choose sensibly. When it calls the number "proprietary," you are left guessing, and the position of retinol low in the ingredient list often points to a small amount.
This formula also contains glycolic acid, an exfoliating acid, alongside the retinoid. Combining strong actives can add up to more irritation, especially early on.
It uses real retinol and is widely available and inexpensive, which has value — the retinoid you keep using beats a better one you quit. Just know what you are, and are not, being told.

It contains real retinol — not an ester — and it is available in every drugstore in the country for under $30.
It has been on the market for decades, and a great many people have used it happily.
Accessibility counts for something. A retinoid you will actually keep using beats a better one you abandon.
Irritation is expected, not a sign it is "working." Redness, flaking and stinging in the first weeks are common with any real retinoid. Start twice a week and build up. If it is still angry after a few weeks, the dose is too high for you.
RoC refuses to disclose how much retinol is in it, calling the concentration "proprietary information."
That is not a real constraint — it is a choice. The Ordinary, SkinCeuticals, Peter Thomas Roth, Medik8, Drunk Elephant and Good Molecules all disclose theirs. Nothing prevents RoC from doing the same.
And the ingredient list is not reassuring: retinol sits below the fragrance, below the parabens and below the shea butter — which strongly suggests a low concentration. We will not print a number, because RoC will not, and every figure circulating online is a guess.
It contains fragrance, parabens, and glycolic acid — an acid, alongside a retinoid, in a product that will already be irritating.
It ships in a screw-top jar, exposing a light- and air-sensitive active every time you open it.
"#1 Most Awarded Retinol" and "97% saw results in 1 week" are marketing claims wrapped around a dose the company will not name.

Spectral and mass characterization of kinetic conversion from retinoids to retinoic acid in an in vitro 3-D human skin equivalent model (https://doi.org/10.1016/j.ejps.2024.106784) — Confirms that free retinol bioconverts to active retinoic acid in skin whereas retinyl palmitate (an ester) shows no such conversion, backing the claim that 'real retinol' differs from an ester. 2. Prospective, randomized, double-blind assessment of topical bakuchiol and retinol for facial photoageing (https://doi.org/10.1111/bjd.16918) — Reports that retinol users experienced significantly more facial skin scaling and stinging, supporting the claim that irritation such as flaking and stinging is common with a real retinoid. 3.
