Thanks for speaking slowly. Some of these skincare peeps talk way too fast

[kym.etherington]

i thought i had PIH & i literally have PIE, it's literally identical to the pictures, i feel so so much more knowledgable! i had roaccutane & doxycycline for my skin & ever since i stoppped ive had the redness so hopefully i can try some of this!💙

[realquick]

Ive had PIE for about 2 years and it still hasnt faded. Im gonna start using products now

[micaelaisabelle]

My acne/PIE started getting really bad due to picking my face, diet, stress and sun exposure. I’m taking a pill my dermatologist prescribed to help reduce oil production since I have oily skin. I cut dairy out of my diet and created a skincare routine using cerave foaming face wash in the morning then moisturizer and sunscreen and nighttime youth to people green cleanser, ordinary niacinimide then moisturizer and my skin is visible looking better. Thank you for the advice, I can see a difference with my PIE!

when you said get acne under control first 😭😭 if only i knew how

[MegaGabby]

tysm for this video! i have acne under control and don’t really get new pimples but my skin is covered in both pie & pih, it’ll take forever for the marks to fade bc i used to not do anything to protect my skin from the sun :( wish me luck hopefully they’ll fade by the end of the year

[chaelisa]

Omg 😱
You’re so educated about skincare
I have Indian skin
I mean my skin is not entirely black or white
It’s in between!
But today I looked closely that my dark spots are actually in pink & purple.
That means I have PIE 🤭
Edit: I realised I have both pih & pie

[EliannedeJong]

I love the chapters!
Also just found out I have PIE instead of PIH lol

[commenter]

Your channel is a skincare goldmine! I really appreciate the knowledge you’re passing on.

[inaya]

Great video! If you're a person of colour suffering with hyperpigmentation, I would say go for mandelic acid rather than glycolic acid. It''s much gentler than glycolic acid, whereas glycolic acid is much harsher and could cause irritation because of how vulnerable it makes your skin. They're both brilliant AHAs but mandelic acid is generally a better option for poc.

[msEPIC]

I bought a bunch of the ordinary products and you’ve mentioned most of it. 🤩 hope it works for me

[briantavarez]

guys the comfy water leaves a bad white cast on my skin, get the purito centella one!

UPDATE: DONT GET PURITO CENTELLA LOL ITS BEEN PROVEN A SPF 19 NOT 50 😔

[silviadelacera]

what if i still have acne but also have hyperpigmentation from previous pimples?

[angeloscofield]

Girl, are you new on YouTube, damn I'm glad I found you! You're gooood .

[britt]

Thank you for this. I ended up using a lot of new skincare for the first time and broke out with cystic acne and I stopped but since then Iv had the red marks on my face for 4 mos now, I’ll def be trying what you said in the videos!
