The world of skincare can sometimes feel like a jungle Creams, oils, masks, toners… and of course, the famous serums. But one question often comes up: at what age should you start using a face serum? Is it only for mature skin? Is it too early at 20? Too late at 40? Spoiler alert: there isn't one single right answer, but several factors to consider. Let's take a closer look!
What makes a good face serum?
Before talking about age, it is important to understand what a serum is.
A face serum is a concentrated treatment in active ingredients, designed to target a specific skin need: hydration, radiance, anti-aging, imperfections, pigment spots… Its texture is often more fluid than a cream, which allows it to penetrate quickly and deeply.
It is usually applied before moisturizer, morning and/or evening, depending on your needs. In short: serum is the superhero of facial care. It works deep down where cream works more on the surface.
What is the ideal age to start using a serum?
There's no hard and fast rule, but around 20-25 years old is often the ideal time. Why? Because collagen production starts to slow down. This is the beginning of skin aging, and this is when serum can prevent the first visible signs such as fine lines, loss of radiance, or fatigue around the eyes.
Before the age of 30, a serum can be useful for targeting specific needs: excess sebum, dehydration, blemishes, etc. You don't need a powerful anti-aging treatment, but rather a gentle product enriched with natural and hydrating ingredients to meet your skin's current needs. Using a serum won't tire your skin if you choose the right one.
At what age should I start anti-aging treatments?
From the age of 25-30, you can incorporate anti-aging serums into your routine. They will help slow down the signs of skin aging, such as loss of firmness or fine lines around the eyes. Treatments based on vitamin C, hyaluronic acid, or gentle retinol are very effective at boosting radiance and strengthening the skin barrier.
How to choose a serum based on your age?
● Before age 25: a purifying or hydrating serum
● Between 25 and 35 years old: a radiance and prevention serum
● After 35: a more targeted anti-aging serum (firmness, anti-dark spots)
● After 45: more regenerating and firming treatments
In all cases, you choose a cosmetic that contains the right ingredients, adapted to your skin type and your current needs.
How to properly incorporate a serum into your routine?
Here is the correct technique:
- Cleanse your face with a gentle cleanser
- Apply your serum to clean skin; a few drops are enough.
- Fingertip massage
- Finish with your day cream
This daily use allows the serum to work in synergy with the rest of the routine, for a reinforced effect.
Should serum be changed according to the seasons or stages of life?
Yes, your skin doesn't have the same needs in winter as in summer. You can also alternate depending on your hormonal cycle, stress level, or sun exposure. Ideally? Observe your skin's reactions and adjust your usage accordingly.
The final word: listen to your skin, not your age.
The key is to listen to your needs. Age is just a number. It's the signals your skin sends you that matter. And if you choose the right products, you can transform your routine into a moment of sensory pleasure that's effective and gentle on your skin.
