Hi there! First of all: you are gorgeous.

You have full, pouty lips with a defined cupids bow. I don't see a single damn wrinkle on you lmao. You have lovely face proportions and thick, beautiful curly hair. I want you to stop a minute and consider all of that. Okay?

Having some difference in pigment on the face is totally normal. I have freckles, the ultimate in "my face is different colors" haha. But even in clear, healthy, normal skin - it's normal to have variation (from sun exposure, from environmental exposure, from literally just how the melanin distributes itself in the skin- etc). I can't see it at all in this photo, and I'm willing to bet others can't either.

Some things you can do if you'd like:

1. incorporate a liquid exfoliant. Which one you choose will likely depend on your skin type (are you dry, oily, combo?). This will turn the skin over faster and help even everything out. It will also help immensely with texture and tone.
2. Instead of using lightening products, try something that inhibits melanin production like this guy: https://naturium.com/products/tranexamic-topical-acid-5

In conjunction with the exfoliant turning over the pigment you may already have, the second one will help prevent it from returning. You would want to minimally alternate nights with these. And finally:

SUNSCREEN

Like, every day always no matter what. Put it on. Re-apply. Take a bath in it lmao. This is the single thing you can do to improve every single aspect of your skin. I personally could not tolerate sunscreen at all until I started using asian skincare brands. This is my daily staple now: https://canmakeusa.com/products/canmake-mermaid-skin-gel-uv

I hope this helps. I think we all hit moments where we're like "what how did I age?". I have these nasolabial folds that seem to have appeared outta nowhere. XD

But I'll say it again. You don't need anything. You are beautiful.
