Skincare ingredients you can and can’t mix

Hey dear readers! Happy Fall! I’m back in both languages, so enjoy there my fellow foreign followers! I feel the blogging world is so saturated with everything beauty-related I decided to take a step away from that. That’s why I won’t be doing this much of New in posts anymore, but only some of the more educational ones related to beauty. You can always see my new bits and pieces on my Instagram here, click. So today, to open the English side of my blog, I have some info for you about mixing the cosmetic ingredients together. What can you use together and what should you stay away from mixing?

Mix together for the perfect skin results:


  1. AHA/BHA and Hyaluron:  Hyaluronic acid is basically a moisturizer and works really well with all skin types. You can for sure use it in skincare combination with AHAs and BHAs, because they clean pores and prepare your skin for the moist bomb!Note: AHAs should be at first used up to two times a week (for beginners). Both AHA or BHA can remove the top skin layer, so you are more prone to UV damage. You should always wear at least 30 SPF protection whilst using AHA/BHA! Most AHA sources are fruit, milk and sugar, so you can find AHAs under the name: Glycolic acid, Lactic acid and Malic acid. BHAs are perfect for oily skin with more sebum, blackheads, etc. The most common known BHA is salicylic acid.
  2. AHA and BHA: Like mentioned before, BHA acids work in deeper skin layers, AHA are best for top/surface skin layer. Used both together you can be prone to more dry skin, so make sure you moisture your skin afterward.
  3. Hyaluronic acid and Retinol: Retinol is great for reducing aging signs like fine lines and wrinkles because they increase collagen production. For beginners, retinol can cause irritation, so mixing it with hyaluronic acid in you skincare routine can calm the irritated skin.
  4. Retinol and SPF: Retinol is best for the night time skincare, because it stimulates the travel of skin cells and can make your skin more sensitive to UV. Same as with AHA/BHAs, if used during the day, make sure you apply a good amount of SPF on your skin afterward.
  5. Vitamins (for example C and E): they work really good for pollution defense, so they can be used together. VIT C is water-soluble and E is oil-soluble they work in different skin layers. Oil-soluble skincare works on deeper skin levels and water-soluble on the surface layer.
Don’t try mixing these together, like EVER:
    1. Retinol and VIT C: They both increase the UV sensibility, so used together can cause also irritation, redness, skin peel, etc. You can use them on the same day of course, Retinol at night and Vit C in the morning. Careful with Retinol if you have sensitive skin.
    2. Glycolic and salicylic acid: Alltough you can mix AHAs and BHAs, these two both work for removing dead skin cells on the top layer of the skin, so together can cause biiiiig irritation and strip your skin.
    3. VIT C and Niacinamide: Niacinamide works magic on oily skin, acne, redness, etc., but it also stops VIT C to work properly and can together cause major redness and acne breakouts.
    4. Retinol and AHA/BHAs: even reading this together is hard. Mixing those can “damage” the skin barrier leaving your skin sensitive and inflamed. AHAs and BHAs don’ deactivate retinol, although AHAs and BHAs are exfoliants and Retinol is an antioxidant. Some research on resilient skin says they can be used together, but I wouldn’t try.
