AI Skincare Analysis: Benefits and Innovations in 2024

A few years ago, I started caring more about my skin and the use of skincare products. However, the endless stream of products and advertisements online can be overwhelming. Every influencer seems to have a new ‘must-have’ product every other week, and every brand claims to be backed up by science. I wanted to take better care of my skin, but as a student, a dermatologist felt too far out of reach and too expensive to justify.  

I didn’t have any expectations but thought I could ask ChatGPT. I assumed it would just list random products or repeat basic advice like ‘drink more water’ or ‘get more sleep’. Instead, it surprised me. First, it asked for more details about my skin type, sleep pattern and eating habits. After answering these questions, it came back with a full plan: cleansing, moisturising, exfoliating and even ingredients I should avoid. The recommendations were supported by user experiences, dermatological sources and logic that felt personal.

Over time, it began to feel like my own digital dermatologist. I’d ask why my skin was drier when seasons changed or whether stress could trigger breakouts. The explanations helped me become more aware how my lifestyle affects my skin.

I know that ChatGPT isn’t a replacement for medical or professional advice, and I double-checked all products before trying anything new. But it gave me something more valuable than just recommendations: clarity and confidence in my choices. It helped me see through the marketing noise and understand what my skin actually needs.

Maybe that’s the real potential of Generative AI tools: not to replace experts, but to make knowledge more accessible and help us build the confidence to approach professional care with greater awareness.

Scrolling to the Top: TikTok and the Power of Network Effects

TikTok Launches Auto Scrolling. Will It Replace Doomscrolling?

When I originally downloaded TikTok, I assumed it was primarily about dances and funny sketches. It didn’t feel like something deeper, but rather like a distraction or something to do when I didn’t feel like studying. But as I began my master’s degree, it became evident to me that TikTok is more than simply entertainment; it is an immense platform that leverages network effects better than any other.
Eisenmann, Parker and Van Alstyne (2006) define network effects as situations in which a product’s value increases as more people use it. TikTok is a perfect example of this: as more people sign up and create accounts, more content is generated. The more content there is, the better the algorithm develops at offering exactly what someone wants. This cycle is so powerful that TikTok has expanded into a global platform.
Van Alstyne, Parker and Choudary (2016) argue that platforms succeed by arranging interactions rather than generating everything themselves. TikTok’s innovation is not the never-ending stream of different types of videos, but the way in which creators and viewers around the world are connected. A trend that starts overnight in New York can go viral in Rotterdam the next morning.
However, not all network effects are positive. TikTok’s popularity comes from its abundance, but it also contains numerous risks. Dangerous challenges spread almost as quickly, if not quicker, than harmless memes. The constant stream of content can be overwhelming, and there are also privacy and national security issues. For example, in 2025 TikTok was fined 530 million euros by the European regulator for violating GDPR (Reuters, 2025). TikTok demonstrates that network effects can cause platforms to grow rapidly, but their existence ultimately rests on how well they ensure security, privacy and trust.

Do you believe TikTok’s success will continue, or will the negative side of network effects eventually undermine its growth?
