Skincare Science: Real Treatments That Work
Don't let viral hacks damage your skin barrier. I focus on evidence-based dermatology advice that is safe, effective, and tailored to you—no trends, just facts.
Do collagen supplements work? In this video, I break down the science. I explain how your body digests collagen and that while it can improve skin hydration and hair strength, it's a support system, not a magic solution for wrinkles or baldness.
Choosing the right sunscreen can be confusing. I explain how to read the label, including what SPF and PA+ ratings mean, the difference between physical and chemical sunscreens, and how to pick the right texture for your skin type.
We all know sunscreen reapplication is important, but it can be tricky. Here, I demonstrate practical ways to reapply it throughout the day, using tools like sunscreen sticks, powders with SPF, and sprays to stay protected on the go.
Retinoids are a gold standard in skincare, but they can be confusing. This video introduces four simple rules to help you use them correctly and avoid common mistakes for the best results.
Rule number one for retinoids: only use them at night. Sunlight can degrade the active ingredient, making it less potent and effective.
Rule number two for retinoids is to use only a pea-sized amount and always follow with a moisturizer. I also explain the "sandwich method" to minimize irritation and dryness.
Rule number three is non-negotiable: wear sunscreen every single morning. Retinoids can make your skin more sensitive to the sun, so daily SPF is essential for protection.
Rule number four for retinoids is to start slow. I recommend using a low-concentration formula just twice a week initially to allow your skin to build tolerance and reduce potential side effects.
Using too many active ingredients at once can overwhelm your skin. I explain the importance of mindful layering and provide a helpful screenshot guide of good and bad ingredient pairings, like not mixing retinoids with AHAs in the same routine.
More is not always better when it comes to active ingredients. Overusing products like retinol or exfoliating acids can damage your skin barrier, leading to redness and irritation. Your skin needs rest days to heal.
About Skincare Science: Your Guide to What Works
You might be tempted to layer five different serums because you saw a reel that promised instant glass skin. But please, stop. Combining too many potent ingredients—like mixing retinoids with strong AHAs—doesn't speed up results; it destroys your skin barrier, leading to redness and irritation. Your skin needs simplicity and rest, not an overload of actives. Let’s build a routine that actually supports your skin health instead of stressing it out.
Why Your Skin Needs a Break
Social media often pushes the idea that 'more is better.' You see an influencer using a peel, a retinol, and a brightening serum all at the same time, and you want to follow suit. In reality, your skin barrier acts as a shield. When you bombard it with too many active ingredients, that shield cracks. The result is chronic sensitivity, breakouts, and redness that can take weeks to reverse.
The Science of "Skin Cycling"
Instead of aggressive layering, I recommend skin cycling. This is simply rotating your active ingredients to give your skin recovery time:
- Night 1: Retinoid/Retinol.
- Night 2: Exfoliation (AHAs or BHAs).
- Night 3 & 4: Rest and hydration (focus on ceramides and moisturizers).
This method allows your skin to repair itself between treatments, ensuring you get the benefits of the ingredients without the side effects.
Common Skincare Myths I'm Often Asked:
- "Do collagen supplements replace topicals?" They aren't magic. Your body breaks them down into amino acids. They might support hydration, but they aren't a replacement for your daily skincare.
- "Is it okay to skip sunscreen indoors?" Absolutely not. UVA rays penetrate glass. If there is daylight, you need SPF. It is your best tool against premature aging.
- "Can I use chili to plump my lips?" Please, no. This is a dangerous trend that causes inflammation, not collagen production. It will only lead to long-term pigmentation and damage.
My advice is always: Keep it simple. If you are struggling with a routine that is causing more harm than good, let’s talk and fix it.
