Hello, @KaylaU8!
I used to have horrible cystic acne that I'd pick at and of course it resulted in scarring. I was Accutane for 9 months and that cleared up all the acne (and i haven't gotten a bad breakout since, just little zits here and there!) but unfortunately it hasn't done much for my scars. My derm said the scarring would heal itself after a year, but it's been 3 years since I've been off it and no change. I went back last summer and asked if anything can be prescribed, and she gave me Retinol. While that helps a little, it's incredibly drying and I'd rather not relive my Accutane days where I had peeling skin nonstop.
ANYWAY, I've done lots of comparing with products that are over the counter, i.e. found at Sephora, and I have to say Drunk Elephant's C-Firma is one of the best for this. In store, I've had a lot of SA's try to turn me onto Caudalie's VinoPerfect Serum, but the dropper + exposing the serum to air/light is a turn off to me. Also, according the BeautyPedia (I think that's the site?) the active ingredients don't even have enough potency to do much anyway. However, C-Firma's 15% Ascorbic Acid packs a punch as far as products you can find without a prescription.
Keep in mind though, whatever product you do use, it'll take weeks, even months, before you'll see a result especially if the scars have been around for a while. I cannot yet speak for C-Firma's ability (I've only been using it for about a month) to rid the worst of my cystic acne scars, but it's doing wonders on the pigmentation I get from the occasional zit.
Some qualms about C-Firma:
- Scent, there's no added fragrance to this product so what you're smelling is natural. Some describe the scent as hot-dog-like (lol!) or even pumpkin-y. Either way, the scent does not linger so don't let that deter you
- Can be drying. I have not experienced this (I have dry/normal skin), so with combo skin I think you should be fine and also incorporate a good moisturizer!
- The color. If you have an prior knowledge about vitamin C serums, you'll know that when the color starts turning yellow/orange that the product has oxidized or gone bad. The color of this serum is natural orangey so you might think the worst. However that's the natural coloring and as long as you use the bottle up in 12 months, everything should be fine.
- The price. Yes this is pretty pricey, but my prescription retinol was $100 with more adverse side effects. It's true that you don't need to spend a lot of money to get things that work, BUT for a serum, I would not trust anything from the drugstore.
Also a word of advice, to get the most out of your serum(s) or any product in general, don't forget to exfoliate 2x a week! This gets rid of dead skin lingering around and allows products to penetrate deeper so there's a better chance of healing older scars. My favorite atm is OleHenriksen's Transforming Scrub!
Since you have fair skin, I think you'd see results pretty quickly, so I'd give C-Firma a shot! Keep in mind, with any Vitamin C product to use sunscreen always!
Good luck 😄
