I'm Very Memorable, But I'll Make You Forgettable

Do you think that I can hide you from your friends?
I'll have them seeing you through a different lens.

So don't be surprised if you can't recognize,
Given that I'm a very familiar guise.

Underneath all these lies, I'll protect what you hide,
I'll convince all their eyes, your secret is what I pride.

So beware what you see, this face smiling happily.
Ere what you were, will be forced upon you unhappily.

What am I?

• @maxathousand, very interesting theory. Maybe I'll make a future puzzle about that. Commented Sep 10, 2018 at 16:34
• Love this riddle, especially the title. Also, looking forward to your potential future puzzle! DVL2 $\color{darkorange}{\bigstar}$ :D Commented Sep 10, 2018 at 21:32

Third try!

Makeup

Do you think that I can hide you from your friends? I'll have them seeing you through a different lens.

People look totally different with makeup on.

So don't be surprised if you can't recognize, Given that I'm a very familiar guise.

Celebrities with no make are almost unrecognizable

Underneath all these lies, I'll protect what you hide,

Maybe dark circles under your eyes.

I'll convince all their eyes, your secret is what I pride.

People put a lot on.

So beware what you see, this face smiling happily. Ere what you were, will be forced upon you unhappily.

They think they have to in this society. (and makeup can run if you cry).

Hidden hint

The first letter of each line spells disguise.

I think the answer might be

Sunglasses

As Shahriar pointed out

The acrostic spells DISGUISE

Do you think that I can hide you from your friends?

Sunglasses can be used as part of a disguise.

I'll have them seeing you through a different lens.

Glasses have lenses

So don't be surprised if you can't recognize,

It's not always easy to recognise a person if they are wearing sunglasses.

Given that I'm a very familiar guise.

Sunglasses are worn by people in many different situations, especially on a sunny day.

Underneath all these lies, I'll protect what you hide,

Your eyes, the windows to the soul.

I'll convince all their eyes, your secret is what I pride.

Your eyes can often give away what you are thinking.

So beware what you see, this face smiling happily.
Ere what you were, will be forced upon you unhappily.

Even though somebody appears to be smiling, you cannot always tell their state of mind unless you see there eyes.

• Another really good guess. This one is the closest yet, though not quite what I'm searching for. Commented Sep 10, 2018 at 15:44

Are you

Photographs?

quite old photographs of people are almost unrecognizable

Underneath all these lies, I'll protect what you hide, I'll convince all their eyes, your secret is what I pride.

There's a saying "People change, photos doesn't"

So beware what you see, this face smiling happily. Ere what you were, will be forced upon you unhappily.

Say cheese doesn't always mean that you are happy to be clicked

• Whoa great answer! Commented Sep 10, 2018 at 15:53

• @Joe-You-Know I am now thinking of rot13(Qvffbpvngvir Vqragvgl Qvfbeqre). What do you think? Commented Sep 10, 2018 at 16:00
• Ooh, that's another good answer. However, QuantumTwinkie got the right answer. Commented Sep 10, 2018 at 16:01
• Oh. That's great! Commented Sep 10, 2018 at 16:01

Is it-

Disguise , that is written in the acrostic.

• It is a type of one, though much more specific. Commented Sep 10, 2018 at 15:32

Are you a

Costume

Umm, a creepy clown smile/face paint.

Halloween costumes?

Hidden hint

• Not the answer I'm looking for, but a great guess nonetheless. It's in the right direction. Commented Sep 10, 2018 at 15:33
• Is it a type of rot13(Pbfghzr)? @Joe-You-Know Commented Sep 10, 2018 at 15:35
• In the strict definition, I would say no. It's something everyone sees every day. Commented Sep 10, 2018 at 15:35

Well, perhaps many answers are provided, but I prefer going with

Which hides one's identity and also gives a memorable experience.

• The true answer is a type of this, but really good guess. Commented Sep 10, 2018 at 16:34

Are you

Alcohol?

Do you think that I can hide you from your friends?

People often drink in social situations to "loosen up", which could be thought of as hiding your true personality.

I'll have them seeing you through a different lens.

You act different when you consume alcohol.

So don't be surprised if you can't recognize, Given that I'm a very familiar guise.

People don't realize how it is affecting them in the moment.

Underneath all these lies, I'll protect what you hide, I'll convince all their eyes, your secret is what I pride.

So beware what you see, this face smiling happily.

Ere what you were, will be forced upon you unhappily.

The alcohol eventually wears off and you go back to normal. Possibly with a hangover, which could make someone unhappy.

• An interesting interpretation. The answer is a little more directly related to the hints than this. Commented Sep 10, 2018 at 15:42

Another Guess

Contacts

Do you think that I can hide you from your friends? I'll have them seeing you through a different lens.

They might not know you need glasses.

So don't be surprised if you can't recognize, Given that I'm a very familiar guise.

Lots of people have them!

Underneath all these lies, I'll protect what you hide, I'll convince all their eyes, your secret is what I pride.

You can hide your eye color or that you have bad eye sight.

So beware what you see, this face smiling happily. Ere what you were, will be forced upon you unhappily.

It hurts to put them in???

• I'm glad the answers are starting to get much closer to what I intended it to, but these answers are focusing too much on the eyes alone. It's something people see everyday, that constantly lies to people, which may be covering up for some sort of unhappiness. Commented Sep 10, 2018 at 15:50
• Could it be rot13(Znxrhc)? @Joe-You-Know Commented Sep 10, 2018 at 15:52
• Yes, yes it very well could be. Commented Sep 10, 2018 at 15:53
• Should I answer with it or edit my post? @Joe-You-Know or is it wrong? :) Commented Sep 10, 2018 at 15:54
• It's different enough where you can post it as a different answer. It's right. Commented Sep 10, 2018 at 15:54

Well, this is my first post, and this riddle is nice.

My first guess is

death. It is a sort of mask, may make your friends see you through a different lens, can be familiar, and protect your secrets...

My second guess, probably better, is

any social media platform.

• Hello! Welcome to the Puzzling Stack Exchange (Puzzling.SE)! Congratulations on your very first post! I am glad it contains spoiler tags/quotes (so as to not, well, spoil an idea or potential answer to users who might be attempting to solve the riddle). However, since you are new to the Stack Exchange community (let alone this site!), I strongly suggest you visit the Help Center; and since you have already answered well, I suppose you can skip that part and head here.
