Hoy no llevo mucho maquillaje, solo un poco de pintalabios.

Yes. In Spanish, llevar is very commonly used to mean to wear something on your body, including clothes, accessories, perfume, and makeup.

So llevo maquillaje means I’m wearing makeup.

A few related verbs:

• llevar = to be wearing
• ponerse = to put on
• usar = to use / wear, but with makeup llevar usually sounds more natural in this kind of sentence

Examples:

• Hoy llevo vestido. = I’m wearing a dress today.
• No llevo gafas. = I’m not wearing glasses.
• Se ha puesto pintalabios rojo. = She has put on red lipstick.

In standard Spanish, no goes directly before the conjugated verb to make the sentence negative.

So:

• Llevo mucho maquillaje. = I’m wearing a lot of makeup.
• No llevo mucho maquillaje. = I’m not wearing a lot of makeup.

This is the normal pattern:

• No + verb
• No como carne.
• No tengo tiempo.
• No llevo mucho maquillaje.

Spanish often leaves out subject pronouns because the verb ending already shows who the subject is.

Here, llevo clearly means I wear / I am wearing, so yo is unnecessary.

• (Yo) llevo
• (Tú) llevas
• (Él/Ella) lleva

You could say Hoy yo no llevo mucho maquillaje if you want extra emphasis, contrast, or clarification, but in normal speech it is usually omitted.

Because maquillaje here is being treated as an uncountable noun, like makeup in English.

You normally talk about it as a substance or general amount:

• mucho maquillaje = a lot of makeup
• poco maquillaje = little makeup

You would not usually say muchos maquillajes unless you meant different kinds, styles, or products in a very specific context.

Also note:

• mucho agrees with maquillaje, which is masculine singular
• so it stays mucho

Compare:

• mucho maquillaje
• mucha crema
• muchos productos
• muchas brochas

Because un poco de is a fixed quantity expression in Spanish.

The structure is:

• un poco de + noun

So:

• un poco de agua
• un poco de tiempo
• un poco de maquillaje
• un poco de pintalabios

Without de, it would be ungrammatical in this sentence.

You can think of un poco de as meaning a little bit of.

Yes. solo and solamente can both mean only here.

So these are both possible:

• Hoy no llevo mucho maquillaje, solo un poco de pintalabios.
• Hoy no llevo mucho maquillaje, solamente un poco de pintalabios.

Solo is shorter and very common in everyday speech.

Also, modern standard spelling usually writes solo without an accent, even when it means only. You may sometimes still see sólo, especially in older texts or if a writer wants to avoid ambiguity, but solo is the normal modern form.

Not exactly.

• maquillaje = makeup in general
• pintalabios = lipstick

So the sentence contrasts:

• not much makeup overall
• only a little lipstick

In Spain, pintalabios is a very common word. In other Spanish-speaking countries, you may also hear:

• labial
• lápiz labial

But for Spain, pintalabios is perfectly natural.

Because after quantity expressions, Spanish often uses the noun without an article.

Here you have:

• mucho maquillaje
• un poco de pintalabios

That is normal.

Compare:

• Tengo mucho trabajo.
• Bebo poca agua.
• Quiero un poco de pan.

You do not need el or un before those nouns in this structure.

Yes, and it would be very natural, but the nuance is slightly different.

• Hoy llevo poco maquillaje = Today I’m wearing little makeup.
• Hoy no llevo mucho maquillaje = Today I’m not wearing much makeup.

They are very close in meaning. The version with no mucho can sound a bit softer or more conversational in some contexts.

Both are correct.

Yes, hoy is flexible.

These are all possible:

• Hoy no llevo mucho maquillaje.
• No llevo mucho maquillaje hoy.
• Hoy llevo solo un poco de pintalabios.

Putting hoy first is very common when setting the time frame right away: as for today...

So the original sentence sounds completely natural.

Yes. Spanish normally uses the present tense for current states and what someone is wearing at the moment.

• Llevo maquillaje. = I’m wearing makeup.
• Llevo una chaqueta. = I’m wearing a jacket.

Spanish does not need a special continuous form here. The simple present already works well.

It adds a contrast or clarification:

• not much makeup
• just a little lipstick

The comma helps separate the second idea, which explains what the speaker does have on.

You could think of it as:

• Today I’m not wearing much makeup, just a little lipstick.

This kind of comma is very common when adding a short corrective or limiting phrase after the main statement.

Yes. In this sentence, pintalabios is being used as an uncountable or general product noun, much like lipstick in English.

So:

• un poco de pintalabios = a little lipstick

That sounds natural.

You may also hear it as a countable item in other contexts:

• He comprado un pintalabios rojo. = I bought a red lipstick.
• Tengo varios pintalabios. = I have several lipsticks.

So it can behave both ways depending on the meaning.
