Anua Nano Retinol 0.3% + Niacin Renewing Serum

The name says 0.3%. Anua's own ingredient list says the retinol is 0.11%. Both are true — and that is the problem.
At a Glance
Mixed

This is the most common label trick in the category. A percentage like "0.3%" usually describes the encapsulated retinol raw material, not the pure active. Anua's own ingredient list states retinol at 0.11%, so the number on the front of the box is nearly three times the number in the bottle.

Both figures are technically honest, which is what makes it confusing. To find the real dose, read the ingredient list rather than the product name.

The rest of the formula is thoughtful. Niacinamide at 5% is the studied level and supports the barrier, and the ceramides and peptides help. For a beginner, 0.11% is a reasonable starting strength.

How it works

Niacinamide at 5% is exactly the studied dose, and it is a genuinely good pairing — niacinamide supports the barrier, which is the thing retinoids compromise.

The supporting formula is thoughtful — ceramides, peptides, centella. For a first retinol, having barrier support built in is sensible.

$25, and the actual retinol dose (0.11%) is a reasonable beginner strength.

And to Anua's credit, the real number is in their ingredient list. You just have to go looking for it.

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.

Everyday habits

How to use it
  • When: Start 2 to 3 nights a week, always at night.How much: Use a pea-sized amount for the whole face. Steps: Apply to clean, dry skin. To reduce irritation, you can buffer by applying moisturizer first, then the product, then more moisturizer. Sunscreen: Wear sunscreen every morning. Retinoids make skin more sensitive to the sun. What to expect: This is a low dose, so early dryness is usually mild. Build up the number of nights slowly. Careful: Avoid the immediate eye area. Do not layer it with other strong actives at first.
Who should be careful+

The "0.3%" in the product name is not 0.3% retinol. Anua's own published ingredient list states retinol 0.11%.

The 0.3% refers to the nano-encapsulated retinol raw material — the complex, not the active. Both numbers are honest in isolation. Together, the one on the front of the box is nearly three times the one in the bottle.

This is the single most common trick in this category, and it is worth learning to spot: when a brand says "0.3% retinol complex" or "0.5% retinol complex," the percentage almost always describes the encapsulated ingredient, not pure retinoid.

It contains tea tree oil and lavender extract — essential-oil components, in a product aimed at skin that is about to become irritated.

The ingredient list runs to over 90 items. More is not better; it is more things to react to.

Questions people ask+
Is it really 0.3% retinol?No. The ingredient list states retinol 0.11%. The 0.3% refers to the encapsulated material.
Is it fragrance-free?No. It contains tea tree oil and lavender extract.
Is it good for beginners?Yes. The low dose and barrier support suit beginners, aside from the essential oils.
Why is the ingredient list so long?It runs to over 90 items. More ingredients means more things to potentially react to.
Is the niacinamide dose meaningful?Yes. 5% is the studied level.
