New to routine - using Olive young products

I recently started the routine. Morning - Toner, eye cream, vitamin c & origin's moisturiser+uv. In the night - Toner, eye cream, peptide/ retinol, snail cream. I have a sensitive skin. First 2 weeks of using the above routine, didn't notice any acne. Since 4days, my skin is red with small acne. Is this normal or should i change something? I tried removing snail cream for a day and it slightly helped. I am thinking to give a break from routine too. If anyone had same issues, let me know what helped you. TIA
