Don't Mix: AHA/BHA acids with retinol. "I strongly caution those also using retinoids for acne or anti-aging as the combination with various acids may cause excessive skin sensitivity, irritation, and redness. In fact, AHA and BHA should not typically be used together with retinoids on the same day," explains Dr.
Short answer is: Yes! You certainly can. To make niacinamide and AHAs/BHA work together, layer them on your cleansed face—just 30 minutes apart. You can also use them at different times of day, use niacinamide in the morning and AHAs/BHA at night.
Can you use an AHA or a BHA together? “It is indeed safe to use AHAs and BHAs together. They target different actions (as discussed above) so they have different benefits. In essence, BHAs disrupt the connections between dead cells whilst AHAs cause dead cells to detach and slough away.
It's possible to use Niacinamide and BHA apart. First, apply BHA, wait at least 30 minutes, then Niacinamide. That should give it appropriate time so both products can work at their intended pH level. When layering skincare products, always go from lowest to highest pH.
“AHA, BHA, retinol, and benzoyl peroxide can be mixed with moisturizing ingredients like hyaluronic acid, ceramides, and rosehip oil to get effective results — just ensure you are not using retinol as well as AHA or BHA's during the day," says Graf.
The short answer is yes you certainly can! The longer, more detailed answer, is there are a couple of ways to truly benefit from using niacinamide after using AHA and BHA. To avoid any redness or irritation from overusing potent skincare ingredients you can alternate which time of day you use them.
Can I Combine AHA/BHA With Hyaluronic Acid? Yes! In fact, this is an ideal combination. Hyaluronic acid doesn't function like an AHA or BHA in that it does not strip your skin — it's actually highly nourishing and hydrating, so having “acid” in the name is a bit misleading.
To fight the good fight against acne, you may also use salicylic acid, a beta hydroxy acid (BHA) that increases skin cell turnover, to keep pores clear. But on its own, each can dry out the skin, so together they should be combined with caution.
Can you use BHA and vitamin C together? Yes, you can, but only if you use each ingredient properly in your routine.
Niacinamide & Acidic Ingredients. It's the same rule as above, just switch retinol for niacinamide. Don't mix niacinamide with acidic skincare ingredients like AHA's/BHA's and vitamin C.
Can niacinamide and salicylic acid be used together? The simple answer is yes. They complement each other well. Being oil soluble, salicylic acid can penetrate deeper into the skin layers, but it can also dehydrate and irritate skin.
It is considered the best idea to apply niacinamide before salicylic acid. This is because the humectant traits of niacinamide ensure the natural skin barrier contains the correct levels of water. When the skin barrier is moisturised and healthy it can keep itself protected from exposure to free radical damage.
Niacinamide tends to work best in an environment with a neutral pH and because salicylic acid is, well, an acid it does not have a netural pH – it has an acidic one. If you want to use them both one after the other, the best thing to do is apply your salicylic acid, wait 10-30 minutes then apply your niacinamide.
Hyaluronic acid is a skin hydrator, not an exfoliant like salicylic acid. You can definitely use both. In fact, applying hyaluronic acid with your salicylic acid is a very good idea. Salicylic acid can be a little drying to the skin because it's job is to absord excess oil.
