These days, we have a somewhat more nuanced view of when skin starts to age. Researchers participating in a study for the skincare brand Olay found that cell processes change with each decade of life. As the effects of those changes accumulate, they become more noticeable.
The study analyzed the genes of more than 200 women across a range of racial backgrounds and pinpointed five cell processes that slow or decline at five milestone ages.
Milestone 1: Your 20s
During your 20s, your body’s natural antioxidant production declines, leaving your skin more sensitive to damage. Aside from moisturizing and staying hydrated, you can ease this change by eating healthy, whole foods that are rich in antioxidants.
Milestone 2: Your 30s
The collagen produced by your skin declines along with your metabolism during your 30s. Study authors suggest counteracting the flagging bioenergy of your skin with vitamin B3.
Milestone 3: Your 40s
At some point in your early 40s, the cells that make up your skin tissue stop dividing and replicating themselves. Skincare ingredients such as retinol, glycolic acid and peptides can help delay this process.
Milestone 4: Your 50s
During your 50s, your skin barrier function weakens leading to problems with skin hydration. Regular use of rich oils and moisturizers can help minimize potential damage from dry skin in your 50s.
Milestone 5: Age 60 and Older
At this point, the previous aging processes begin to accelerate. However, regular exercise can work to improve the structure of the skin, reducing the effects of the aging process.
