A question
Hi! It says that you shouldn't mix this with retinol. Is there any special ingredient that clashes with it? I've read that it's good to mix, and I also use Niacinamide every day and a retinal serum twice a week that works fine. Can this serum be used together with Estelle & Thild's Super BioAdvanced Vitamin-A 1% Power Booster in the evening?1 product in post A question85 views- The user's roll: Customer service at Lyko.

Therefore, I would recommend using this product and the serum from Estelle & Thild in different routines 🩷 Take care! 🌸1 likes
