The PM Retinol is VITAL in your anti age regime. What RETINOL does is, it increase your cellular turn over.
To explain; when you are 18-21yrs our skin works on a 28 day cycle which is relatively fast. As we age the cycle begins to get longer and longer. 28-45 days by the time we are 30 years old. 45-60 days by the time she are 40, and 60-90+ days are we continue to age.
As cellular turnover slows, dead skin cells accumulate on the surface of the skin causing sagging and collapse of structure or what we see dry dull skin, more fine lines. Can trigger pores to enlarge and expand as they become filled or clogged. Etc.
So to answer your question, yes we 100% suggest using our PM retinol for a 34yr old. Any further questions please done hesitate to ask.
