Dermatologist’s verdict

Mixed

A reasonable beginner's retinol wearing a misleading number. The 0.3% counts encapsulated raw material; the ingredient list puts retinol at 0.11%. Read the list, not the box. If you have used retinol before and want a real step up, buy a plain 0.5% retinol.

What it is

Anua Nano Retinol 0.3% + Niacin Renewing Serum is a lightweight night serum, about $22 to $28. It is a starter retinoid. The 0.3% in the name is the encapsulated raw material, not the active — Anua's own ingredient list states retinol at 0.11%.

Two ingredients do the work — that retinol, in a nano-encapsulation shell that releases it gradually, and niacinamide at 5 percent, a vitamin B3 with good evidence for redness, oil and pigment. Ceramides and peptides sit underneath. The list runs past 90 items, including tea tree oil and lavender extract, the source of the herbal smell.

What it does

A retinoid is converted in the skin into retinoic acid, which binds receptors inside the cell and changes which genes that cell runs. Cells travel to the surface faster, so pore plugs loosen and pigment clears sooner, and fibroblasts below build more collagen. Strength decides how fast that happens and how much it stings.

Which makes the label the thing to read. The 0.3% on the front is the amount of encapsulated raw material, not the amount of retinol. Anua's own ingredient list says retinol 0.11%, so the number on the box is nearly three times the number in the bottle. Both figures are honest in isolation, which is what makes the trick work, and it is the most common trick in this category.

As a formula it is still a reasonable place to start. 0.11% is a real beginner dose, and niacinamide at 5 percent is the studied level for redness, oil and uneven pigment. The encapsulation releases the retinol gradually, which should soften the early sting.

What it treats

## Acne | Moderate Retinoids loosen the plug of dead cells blocking a pore before a pimple forms, which is why they are a first-line acne treatment. At 0.11% this is a slow version, but it is a dose most people can keep using, and 5 percent niacinamide cuts oil at the same time.

## Post-Inflammatory Hyperpigmentation | Moderate The brown mark after a spot heals is pigment in the surface cells. Retinol speeds how fast those cells shed, and niacinamide slows the handoff of pigment from the cells that make it. A sensible pairing for marks fading too slowly.

## Sun Damage (Photoaging) | Moderate Retinoids are the best-evidenced topical for fine lines, because they prompt the cells below to build collagen. A low dose still does this, it just takes longer. Starting low is often the difference between using a retinoid for a year and quitting in week three.

Best for

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

**The number counts the complex, not retinol:** the 0.3% is the nano-encapsulated raw material — the complex, not the active. Both numbers are honest alone. Together, the one on the box is nearly three times the one in the bottle.

**The same wording appears across the category:** this is the most common trick in the category. A "0.3% retinol complex" or "0.5% retinol complex" almost always describes the encapsulated ingredient, not pure retinoid.

**May irritate as it contains essential oils:** tea tree oil and lavender extract, in a product aimed at skin about to become irritated.

**The ingredient list is very long:** over 90 items. More is not better; it is more things to react to.

Texture

Serum A light serum that sinks in within a minute and leaves nothing behind.

It layers cleanly under a moisturizer and does not pill. At this dose early dryness is usually mild, which is the benefit of a low strength.

A faint herbal smell from the plant extracts. If essential oils are a problem for you, that smell is the warning.

How to use it

## How to use it How much: A pea-sized amount for the whole face, on clean dry skin. Water makes a retinoid go in faster and sting more. Layering: If it stings, moisturizer first, then the serum, then more moisturizer. Careful: Retinoids make you burn more easily, so sunscreen every morning is part of using one. Keep it off the immediate eye area, and skip acids on the same nights while you build up. Tea tree oil and lavender are in it, so stop if you get a rash rather than dryness. What to expect: Mild dryness for two or three weeks. Acne can look worse first, because retinoids push existing plugs up. Tone and texture change over about twelve weeks.

The rest of the line

AXIS: Strongest active | Gentlest

Anua's range splits in two — Heartleaf for soothing, and a handful of serums with a real active.

**Nano Retinol 0.3% + Niacin Renewing Serum (this one)** — The only retinoid Anua sells. Retinol at 0.11% with niacinamide, for texture and fine lines.

**Azelaic Acid 10 Hyaluron Redness Soothing Serum | anua-azelaic-acid-10-hyaluron-redness-soothing-serum** — For redness and dark marks. Gentler than a retinoid, usable in the morning.

**Dark Spot Correcting Serum | anua-dark-spot-correcting-serum** — Niacinamide and tranexamic acid, aimed at pigment, not texture.

**Peach 70% Niacinamide Serum | anua-peach-70-percent-niacinamide-serum** — Niacinamide alone. Mild enough to layer with anything.

**Heartleaf 80% Moisture Soothing Ampoule | anua-heartleaf-80-percent-moisture-soothing-ampoule** — No active. A good partner on nights off.
