Myth Busting Common Anti-Aging Claims

Posted by Azadeh Shirazi MD on

The skincare industry is full of many bold claims and viral trends, both true and false. With so much information, and misinformation, floating around the world of skincare, it’s easy to get caught up in trends or believe myths that might be doing more harm than good. When it comes to a strong age-defying routine, I want to encourage you to be educated and empowered to make the best decisions for you. Afterall, you are More Than A Pretty Face. 

Myth #1: Collagen Drinks Help the Skin

This is such a hot topic right now. I see it all over TikTok and while it seems like a miracle fix, the science behind this is still evolving and we just don’t have enough evidence to prove drinking collagen will end up making it to the skin. When consumed, collagen is broken down into amino acids during digestion, just like any other protein. While some studies suggest that certain hydrolyzed collagen peptides might support skin elasticity and hydration, it’s not a miracle maker. The best way to support your skin's collagen is to protect it from UV damage, eat a balanced diet rich in antioxidants, and consider proven treatments. Whether those treatments are topicals like retinoids and vitamin C, or in-office treatments like microneedling and lasers, these are more beneficial and scientifically proven options—which brings me to the next 2 myths.

Myth #2: Retinol Thins the Skin

I can’t tell you how many times I’ve heard this but it’s simply not true. Retinoids actually stimulate collagen production, increasing dermal thickness, and boost cell turnover. Used correctly and consistently (and always with SPF!), retinoids are among the most effective ingredients in your anti-aging arsenal.  

We ran a 12 week, double-blinded, clinical study on our Lift + Renew that showed higher collagen density after consistent use. This directly counters the common myth that retinol thins the skin. In fact, increased collagen production leads to thicker, firmer skin over time, proving that properly formulated retinol products actually support skin integrity and resilience.

If you initially experience dryness or purging, consider Retinol Staging™.  Break up your night routine into two stages: cleanse and moisturize early in the evening (5-7pm) and wait until bedtime (hours later) to apply retinol/tretinoin on its own. Your skin will be better prepared to receive this powerful skincare active when your skin barrier is well hydrated. Unlike Retinol Sandwiching this technique doesn’t reduce the effectiveness of the retinol because the moisturizer has already been absorbed and your skin’s moisture barrier is strengthened before applying retinol on its own. 

Myth #3: Lasers Thin the Skin

Again, simply not true. Lasers work by creating controlled micro-injuries in the skin to stimulate wound healing, collagen productions, and formation of new healthy skin cells. Treatments like fractional CO2 or non-ablative lasers can actually thicken the dermis, smooth texture, and improve tone over time. As with any treatment, the key is working with a trained professional to choose the right settings for your specific skin needs. Laser treatments should be customized to the each patient’s unique skin type and needs so make sure to do your research on the provider you’re seeing.

I have a detailed Youtube video below that goes in depth on the common misconceptions on Lasers. 

Myth #4: You Don’t Need Anti-Aging Products Until Your 40s

Waiting until signs of aging appear to start caring for your skin is like waiting for a cavity to show up before brushing your teeth. Prevention is always better than correction. Incorporating basic steps, like daily sunscreen, gentle cleansers, moisturizers, and a retinoid or antioxidant serum, in your 20s or 30s can help keep your skin healthier, longer.

In-office treatments like botox, microneedling, chemical peels, and regular facial treatments can also be beneficial in slowing down the skin aging process. 

Myth #5: You Don’t Need Sunscreen on Cloudy Days or Indoors

UV rays are incredibly sneaky. Up to 80% of UV rays can penetrate through clouds, and UVA rays, the rays that contribute most to premature aging, can pass through windows and shine through even on cloudy days. That means you’re still exposed indoors or on overcast days. Daily broad-spectrum sunscreen, rain or shine, is non-negotiable if you’re serious about slowing skin aging. There are many comprehensive formulas today that act as a foundation and SPF or a moisturizer and SPF that can make the daily habit much easier. I prefer a mineral based formula like Hydratint BB SPF44, that is tinted, provides broad-spectrum SPF protection while also acting as a moisturizer to hydrate the skin.

As always, it’s best to speak directly with your dermatologist about what treatments, procedures, or skincare options are best for you. Skincare is never one-size-fits-all and should be approached with care.
