Tight, pulling skin. Redness that just won\u2019t go away. A burning sensation at the slightest breeze. More and more users are describing these symptoms after piling on serums, acids, and anti-aging creams in routines that have become endless. The paradox is cruel: in their eagerness to do the right thing, they end up damaging what they were trying to protect.<\/p>\n\n\n\n

Layering: A Strategy That Backfires on the Skin<\/h3>\n\n\n\n

This phenomenon has a name: the multilayering<\/em>. Originating in South Korea, this approach involves layering skincare products. Double cleansing, toner, serum, ampoule, moisturizer, sunscreen. Ten steps\u2014sometimes more.<\/p>\n\n\n\n

This isn\u2019t just a matter of personal taste. Skin sensitization is a cumulative process: every preservative, every fragrance, and every excipient applied daily increases the likelihood that an allergic reaction will eventually occur. The longer the list gets, the more entry points there are.<\/p>\n\n\n\n

Two assets, the same mechanism, double the risk<\/h3>\n\n\n\n

Quantity isn't the whole story. The heart of the matter is interactions.<\/p>\n\n\n\n

Retinol (a vitamin A derivative), glycolic acid (an AHA), and salicylic acid (a BHA) all work on the same principle: accelerating cell turnover. To achieve this, they deliberately weaken the stratum corneum\u2014that thin surface barrier that retains moisture and blocks external aggressors.<\/p>\n\n\n\n

Used separately and systematically, these active ingredients are valuable. When layered on top of each other on the same night, they strip away a barrier that\u2019s already under stress.<\/p>\n\n\n\n

How can you tell when you\u2019ve reached the tipping point? Tightness, widespread redness, and a burning sensation when the skin comes into contact with water. These signs don\u2019t mean the product is \u00abworking.\u00bb They indicate that the skin\u2019s barrier is breaking down.<\/p>\n\n\n\n

Retinol rewards patience, not haste<\/h3>\n\n\n\n

Even when used on its own, retinol is often used incorrectly. The idea that a higher dose would produce faster results is biologically incorrect.<\/p>\n\n\n\n

\u00abIt\u2019s three times a week in the evening, then we increase it to a maximum of five times. And even then, it depends on the skin. On sensitive skin with rosacea, retinol would be a disaster,\u00bb warns Martine Baspeyras.<\/p>\n\n\n\n

It takes several weeks for the skin to adjust to a retinoid\u2014a phase sometimes called \u201cretinization.\u201d Rushing the process doesn\u2019t save time; it causes flaking and inflammation. Since November 2025, the European Union has regulated these concentrations, capping them at 0.3 % for the face and 0.05 % for the body.<\/p>\n\n\n\n
