The number on the bottle is the number in the bottle. 0.2% pure retinol — not a "complex," not an encapsulated raw material, not a blend padded out with things that are not retinoids. Given how much of this category plays games with percentages, that plainness is the product's best feature.
$8. For a real retinoid at a real, disclosed dose, that is the value benchmark.
The squalane base is well chosen — it is a gentle, non-irritating emollient, and it suits dry skin that would struggle with an alcohol-based serum.
0.2% is genuinely the right place to start. Most people who fail with retinoids fail because they started too strong.
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.
