Ole Henriksen Truth Serum Collagen Booster vs Ren Radiance Perfecting Serum
I was looking into buying two kits. One that had Ole's Truth Serum and one that had the REN Radiance Serum. Can they be used together? Are they essentially the same thing? Thank you!!
I've tried Truth Serum, it's liquidy, sinks in fast and feels good. Mmmm, they can be used together but I suggest using them separately. Just like how you can use two cleanser or two moisturizers together, but it's uneccessary. Depending on the ingredients in the two serum, they might decrease the effectiveness of each (I know retinol products and glycolic acid are both great for anti-aging, but when used together they kind of cancel each other out). If you like both, use on alternate days.
