Preserving your skin capital in their twenties

When you're in your twenties, the aim is to maintain your skin's vitality. The first thing to do: avoid dubious advice and the latest trendy products, and focus on what's proven. Here are the five essential steps in a 20-something skincare routine.

Stage 01

Efficient cleaning, but gently

Invest in cleansing - not necessarily by spending a lot, but by finding the right product. Residues of pollution, allergens, SPF and make-up accelerate ageing. At 20, we often have combination to oily skin: cleanse morning and night. On dry skin, cleansing in the evening is sufficient. If the skin feels tight afterwards, the cleanser is too aggressive.

The ratings and review excerpts come from users of the BeautyDecoded application. These reviews are not verified. The Sensitivity Verdict applies the Dr David Rule: a sensitive skin score below 0 indicates a potential risk of irritation; between -2 and -5, a product not suitable for sensitive skin.

Your questions about routine at 20

What kind of skincare routine for 20-year-olds?
A simple routine is all you need: gentle cleansing, niacinamide, appropriate moisturizing and daily sun protection. BHA is added in the case of imperfections and, ideally, vitamin C in the morning. The aim is to preserve, not correct.
Should I already be using anti-aging products at age 20?
No rich anti-wrinkle creams, but the real anti-aging at 20 is daily sun protection and antioxidant vitamin C. These are the most effective preventive measures. Retinol can be considered in your late twenties, in low doses.
Is it necessary to moisturize oily skin at age 20?
Yes, even oily skin needs hydration: if you deprive it of water, it produces more sebum. Simply choose a light texture (gel-cream) that moisturizes without weighing down or clogging pores.
Which asset should I choose at age 20?
Niacinamide is the ideal active ingredient: gentle, versatile and well-tolerated, it regulates sebum, reinforces the skin barrier and brightens the complexion. It's an excellent first active ingredient before introducing more powerful ones.
How often should I exfoliate when I'm 20?
Cell renewal is rapid at this age, so exfoliation is not essential. If you have acne or irregular skin texture, a BHA once or three times a week is sufficient. There's no need to exfoliate more than that, as it may weaken the skin.
