In your mid-20s and beyond…
Your skin is still resilient, but ageing subtly begins. That means that those collagen and elastin levels start to drop with every 10 years that pass, you’ll start seeing fine lines, dullness, and loss of elasticity (it doesn’t bounce back as quickly).
There is nothing wrong with ageing, it’s a part of life. But in your mid 20s, you might want to start considering ingredients that are made to strengthen your skin barrier, protect against environmental stress like pollution and weather.
At this stage, you also want products that boost and maintain hydration and keep your skin working as it should.
