Τον χειμώνα χρησιμοποιώ ενυδατική κρέμα κάθε βράδυ, γιατί το δέρμα μου γίνεται πολύ ξηρό.

Greek often uses the accusative of time without a preposition to express when something happens.

So τον χειμώνα literally looks like the winter in the accusative, but it means in winter / during the winter.

This is a very common pattern:

• τον Αύγουστο = in August
• την Κυριακή = on Sunday
• το βράδυ = at night / in the evening

So in this sentence, Τον χειμώνα is a time expression, not the direct object.

Because the base form of the noun is ο χειμώνας = winter, but here it is in the accusative singular, after τον.

So:

• ο χειμώνας = nominative
• τον χειμώνα = accusative

The final -ς drops, which is normal for many masculine nouns in Greek when they move from nominative to accusative singular.

Χρησιμοποιώ is the 1st person singular present tense, meaning I use.

It comes from χρησιμοποιώ = to use.

So:

• χρησιμοποιώ = I use
• χρησιμοποιείς = you use
• χρησιμοποιεί = he/she/it uses

In this sentence, the present tense shows a habitual action: something the speaker regularly does in winter.

Because the speaker is talking about moisturizing cream in a general sense, not a specific previously identified cream.

So:

• χρησιμοποιώ ενυδατική κρέμα = I use moisturizing cream
• χρησιμοποιώ την ενυδατική κρέμα = I use the moisturizing cream

The second version would suggest a particular cream that is already known from the context.

Yes, it is the direct object, so it is in the accusative.

However, in this case, the forms happen to look the same as the nominative:

• η ενυδατική κρέμα = nominative
• την ενυδατική κρέμα = accusative

If there were an article, you would see the case more clearly. Without the article, ενυδατική κρέμα looks unchanged, but its role in the sentence is still that of the object of χρησιμοποιώ.

Ενυδατική means moisturizing or hydrating.

It is an adjective agreeing with κρέμα:

• κρέμα is feminine singular
• so the adjective is also feminine singular: ενυδατική

Together, ενυδατική κρέμα means moisturizing cream.

In everyday Greek, people can also shorten this and say simply ενυδατική, meaning moisturizer, if the context is clear.

Because κάθε means every / each, and with κάθε, Greek normally does not use the article.

So:

• κάθε βράδυ = every night
• not normally κάθε το βράδυ

Also, βράδυ is a neuter noun, and its nominative and accusative singular forms are the same:

• το βράδυ
• κάθε βράδυ

So the phrase is completely normal as it stands.

It can mean both, depending on how it is used.

In this sentence, γιατί means because, since it introduces the reason:

• ..., γιατί το δέρμα μου γίνεται πολύ ξηρό.
• ..., because my skin gets very dry.

As a question word, γιατί can also mean why?

For example:

• Γιατί χρησιμοποιείς ενυδατική κρέμα;
• Why do you use moisturizing cream?

So the meaning depends on whether it is introducing an explanation or asking a question.

Because γιατί introduces a subordinate clause giving the reason, and in Greek it is very normal to put a comma before such clauses.

So the structure is:

• main clause: Τον χειμώνα χρησιμοποιώ ενυδατική κρέμα κάθε βράδυ
• reason clause: γιατί το δέρμα μου γίνεται πολύ ξηρό

This punctuation is standard and natural in written Greek.

In Greek, possessive words like μου often come after the noun.

So:

• το δέρμα μου = my skin
• literally, something like the skin of me

This is the normal Greek way to express possession:

• το σπίτι μου = my house
• η αδερφή μου = my sister
• τα χέρια μου = my hands

Using the article is also normal in Greek, even where English would just say my.

Because γίνεται means becomes / gets, while είναι means is.

So:

• το δέρμα μου γίνεται πολύ ξηρό = my skin gets very dry
• το δέρμα μου είναι πολύ ξηρό = my skin is very dry

The sentence is talking about a change of condition in winter, so γίνεται is the better choice.

It looks like one, but here it is not passive in meaning.

Γίνεται comes from γίνομαι, a very common verb meaning become, happen, or be done depending on context. It uses middle/passive-type endings, but very often has an active meaning.

Here:

• γίνεται πολύ ξηρό = becomes / gets very dry

So you should understand it as gets or becomes, not as a passive like is made.

Because the adjective must agree with το δέρμα, which is neuter singular.

The forms are:

• ξηρός = masculine
• ξηρή = feminine
• ξηρό = neuter

Since δέρμα is neuter:

• το δέρμα μου γίνεται πολύ ξηρό

This is standard adjective agreement in Greek.

The word order is very natural.

Greek word order is more flexible than English, and speakers often move elements around for emphasis. Here, putting Τον χειμώνα first sets the time frame right away, which sounds very natural.

This version:

• Τον χειμώνα χρησιμοποιώ ενυδατική κρέμα κάθε βράδυ...

highlights in winter first.

You could also say something like:

• Χρησιμοποιώ ενυδατική κρέμα κάθε βράδυ τον χειμώνα...

but that sounds slightly different in emphasis. The original sentence is smooth and idiomatic.
