“Exposure to the ultraviolet rays of the sun causes aging of the skin,” Dr. Sylvia S. Jacinto says, citing as an example that a senior citizen who plays golf regularly would typically have a dark complexion and wrinkled face and arms that are darker than the trunk, but the buttocks are like a baby’s skin: fair and smooth with no wrinkles or dark spots.
The same is true of men and women who go outdoors a lot without the protection provided by a sunscreen lotion. Jacinto recommends applying SPF exposed to the sun, whatever your age.
But inevitably, as time goes on, the years take their toll on our skin despite the regular use of sunscreen.


Tretinoin use treats fine lines and wrinkles, brightens the complexion, and fades dark spots left by acne or sun damage. Because tretinoin is already a retinoic acid, it directly affects the skin.
How Long Does it Take
The time it takes to see the effects of tretinoin getting rid of wrinkles can differ from person to person. It's not an overnight solution, but rather a commitment to gradual improvements. Generally, people may start noticing improvements in skin texture within six to eight weeks. However significant reduction in lines and wrinkles may take months to a year of consistent use.
When it comes to using Tretinoin for reducing sun spots, dark spots, and hyperpigmentation caused by sun damage, the timeline for reducing sun spots can vary. People may notice an improvement in skin tone and a decrease in sunspots within weeks to months. Between three to six months, more significant results may become evident. Dark spots and discoloration from sun damage may start to fade, and the overall complexion can appear more even and refined. However, it's crucial to recognize that deeper sun damage which affects deeper layers of the skin will take longer to treat. Users may need to continue tretinoin therapy for a year or even longer to achieve optimal results in such cases.
It's important to remember that while tretinoin can help reduce sun spots, it's crucial to prioritize sun protection throughout the treatment process.
Using sunscreen with the right sun protection factor (SPF) should be part of your skincare regimen. It helps protect your skin from UV rays and boosts the effectiveness of tretinoin in preventing damage.
It's essential to understand that tretinoin is not a quick fix; it requires patience and commitment to your skincare routine. Initially applying tretinoin may cause some skin irritation, redness, or peeling. These side effects often decrease as the skin adapts to the treatment.
