    Wow, wow, wow.... what a fun video/IG idea!!!! I had so much fun participating and then seeing how the end results compared to how I voted when you had it on your stories. By the way, I voted for retinol because I haven't tried tret. Same with matrixyl, haven't tried it. centella won for me, in the same way glycerin won for you; it soothed my skin at times I thought all hope was lost.

    • @LabMuffinBeautyScience

    • @SusanIvanova2257
      @SusanIvanova2257 5 років тому +44

      Maybe because of availability? I'm in Germany, the only way to get tret here is through a dermatologist prescription. Which has a long waitlist if you're not a urgent case. Also, other people might have more sensitive skin than you this leading them to prefer retinol. Or it might not fit their skin concerns as much, why go through the whole tret dryness dilemma if your skin is mostly good and you just want to do some prevention and hydration with your skincare. If you have next to no acne and no serious aging yet I can see why someone would choose a skincare regimen that isn't as harsh. Or someone who already has seriously dry and sensitive skin would definitely think twice about trying tret

    New subscriber. Came over from Hyram. Loved this! For me Tretinoin is much more effective than Retinol. The amount of difference in my skintone and reduction in wrinkles in the year I’ve been using it has me believing in it over everything else. I’m 42 and I think I look better now than I did when I was 35.

There was a lot of ingredients I haven’t even heard of, I want to research them and would love it if you made a video about the more uncommon ingredients.

  • @theyogainn
    @theyogainn Рік тому +1

    My final showdown would have been zinc oxide vs centella. Sunscreen is the most important, so you can’t not have a sunscreen filter in the final imo. Also, chemical sunscreens irritate my eyes. Zinc oxide is a life saver for me (when I can find it in a sunscreen that doesn’t have a white cast). And centella is just amazing. I feel like it’s soothing, helps speed up wound healing (I put it on any little cuts I get), calms down my redness, and gives me a more even skin tone. I have more dry/sensitive skin tho so I’m biased 😂

    Lol one great advantage of super dehydrated skin: you can layer so many serums, toners, essences, & moisturizers, so u can get full servings of numerous ingredients. My faves are niacinamide, urea, glycerin, squalene, ceramides, peptides, glycolic acid, lactic acid, alpha arbutin, HA, PGA, jojoba, safflower oil, lanolin, petrolatum, beeswax, witch hazel, clay, baking soda, vinegar, and aloe...and I get all of them daily except lactic & glycolic acid. But I still really need a licorice extract product.

    For an azelaic acid product with a nice texture, I've been using Paula's Choice 10% Azelaic Acid Booster - I LOVE it, look forward to putting it on every day! The lightweight, sink-into-your-skin texture was the first thing I noticed about it. I have just ever so slightly oily skin, this felt moisturizing AND not at all greasy - I think all skin types would love it. Definitely give it a try!

  • @megaliberty

    Team Glycolic here. I like it because of its multiple benefits- anti aging, anti acne, and anti hyperpigmentation. It's small molecular size makes it best for anti aging.
    I use a strong product by Organys. These pads are 20% glycolic acid/0.5% salicylic acid, plus they are cheap. My skin has gotten so much smoother, and I don't have significant acne breakouts since I've been using them. I won't use a glycolic product unless I feel a sting after I apply it, because the sting means it's ph is low enough to make a difference. Alpha Skin Care has an excellent and affordable serum as well.
    Vitamin c is my second choice. It's cheap, and easy to mix up your own serum. I keep mine in the fridge and their is never any visible oxidation before I can finish the bottle. While it helps with both anti aging and hyperpigmentation, it does not help with acne like glycolic acid does.
    Don't forget the sunscreen, especially if using a lot of glycolic acid.

    A note on petrolatum...the US does not require it to be fully refined, which results in it possibly containing carcinogens (such as PAHs) and is also known as a mild endocrine disrupter. I go out of my way to avoid it because I have Hashimoto’s Thyroiditis and don’t want to risk additional problems. There may be some petrolatum products in the US that ARE fully refined, but because it is not mandated by law, I just stay away from it altogether.

    I found it difficult because although my skincare routine is minimalist. Many ingredients came to my skin rescue with the acne when I was a teen to my now rosacea... It was indeed difficult to pick the ingredients.
    I would be very curious to find out what other people include in their daily skincare regiment; that could be fun info.

    1st round for me: glycerin, glycolic acid, mineral oil and lactic acid.

    Can you do a video on how to get the most benefits and product absorption out of our sheet masks?

    This is fun but I'm waiting for Michelle's top 10 fav skincare ingredients video.

    Finacea is a beautiful azelaic acid, I get it over the counter in QLD

    Another thing I don't like about benzoyl peroxide- wouldn't it cause free radical damage, since it is a peroxide? I would choose salicylic acid or azeleic acid first for that reason alone.
