Welcome to Skin Insights by YSBB. Facial redness can feel like a red card from your skin. Whether it’s heat, stinging, or just persistent flushing, many patients struggle to tell if it’s rosacea or seborrheic dermatitis.

Let’s break down how to tell them apart — and how we treat each one. 1. Same redness, completely different causes

Welcome to Skin Insights by YSBB. With collagen products flooding the market, which ones truly benefit your skin? Collagen is a vital structural protein that makes up about 70% of the dermis, playing a key role in maintaining skin elasticity and firmness. From collagen creams and drinks to jellies, products touting anti-aging benefits are everywhere. But can these actually boost collagen in the deeper layers of your skin? Today, we'll explore the science behind collagen absorption and production—clarifying the effects of topical and oral collagen, and introducing dermatologist-approved clinical strategies to support skin health. 1. Can Topical Collagen Penetrate the Dermis? Collagen has a large molecular weight, approximately 300,000 Da. The outermost layer of the skin, the stratum corneum, blocks penetration of molecules larger than 500 Da. Therefore, it is widely accepted that topically applied collagen cannot reach the dermis.
2. Can Ingested Collagen Reach the Skin? When taken orally, collagen is broken down in the stomach and absorbed as peptides through the small intestine into the bloodstream. Studies suggest that certain low-molecular collagen peptides may reach the dermis and stimulate fibroblasts to produce new collagen.
However, absorption rates vary significantly between individuals. Oral collagen is better viewed as a supportive measure, not a primary treatment. 3. What Scientifically Proven Methods Stimulate Collagen? As we age, collagen naturally declines, and factors like UV exposure, oxidative stress, and inflammation accelerate its breakdown. In dermatology, various treatments are designed to stimulate natural collagen production in the dermis—targeting the root cause of skin aging.
These techniques work from the inside out, promoting natural regeneration rather than superficially adding substances—offering more lasting and authentic improvement. Final Thoughts Collagen doesn’t get stored in your skin just because you apply or consume it. From a dermatologist’s perspective:
At YSBB Skin Clinic, we offer personalized collagen renewal programs based on precise skin structure and elasticity diagnostics. YSBB Skin Clinic, Seoul, Korea

Welcome to Skin Insights by YSBB. As the temperature rises, air conditioning becomes a daily necessity. But while the cool breeze brings comfort, it may be quietly stressing your skin. Today, let’s explore how air conditioning affects your skin—and what you can do to protect it. 1. Why Does AC Air Dry Out the Skin? When the AC runs, both the temperature and humidity levels in the room drop. This leads to faster evaporation of moisture from the skin. If cold air hits your face directly, skin temperature drops, blood circulation slows, and sebum secretion decreases. This chain reaction weakens the skin barrier and makes your skin more prone to dryness and irritation—especially for those with already dry or sensitive skin. 2. Signs Your Skin Is Stressed by Air Conditioning
