Fine Lines in Your 20s and 30s: Causes and a Simple Routine
Fine lines are small, shallow lines on the surface of the skin. Most people notice their first fine lines on face areas that move a lot, such as around the eyes, the forehead and the mouth, often in their 20s or 30s. Some are dehydration lines that come and go; others are early expression lines from smiling, squinting and frowning.
Fine lines on the face are a normal part of skin aging, and the most effective things you can do are simple: protect your skin from the sun every day, keep it hydrated and use a gentle, consistent routine. This guide explains what fine lines are, why they appear early, and a routine that helps.
What are fine lines?
Fine lines are shallow creases less than about a millimeter deep. Wrinkles are deeper and stay when your face is relaxed. There are two common kinds of fine lines:
- Dehydration lines: fine, crisscross lines, often on the cheeks, that look worse when skin is dry and soften when it is hydrated.
- Expression lines: lines that follow the movements of your face, such as around the eyes when you smile or between the brows when you frown.
Why fine lines appear in your 20s and 30s
- Sun exposure. Ultraviolet light is one of the main causes of visible skin aging, and the effects add up from childhood.
- Natural changes. From the mid-20s, skin gradually makes less of the proteins that keep it firm and springy.
- Dehydration. Dry air, air conditioning and harsh cleansers leave skin short of water, which makes lines more visible.
- Repeated expressions such as squinting at screens or in the sun.
- Lifestyle: smoking, lack of sleep and stress all show in the skin over time.
A simple routine for fine lines
Morning
- Cleanse gently with a soap-free cleanser such as the Niacinamide Daily Cleanser.
- Hydrate with the Hydrating Toner Mist on slightly damp skin.
- Serum. The B3 Lemongrass Anti-Aging Serum combines niacinamide (vitamin B3), hyaluronic acid, vitamin E and agave extract with rose, lemongrass, basil and lemon hydrosols. Hyaluronic acid helps skin hold water, which can soften the look of dehydration lines.
- Moisturize with the All-in-1 Moisturiser with SPF 30.
- Sunscreen. Finish with a broad-spectrum sunscreen such as the Anhydrous Sunscreen SPF 50 PA++++. This is the most important step for fine lines. Apply and reapply as directed on the label.
Night
- Cleanse to remove sunscreen and makeup.
- Tone with the hydrating mist.
- Serum. The same serum.
- Moisturize, a little more generously.
The Anti-Aging Skincare Combo brings the Niacinamide Daily Cleanser and the B3 Lemongrass Anti-Aging Serum together. Our guide to how to choose and use a face serum explains how to apply it.
Habits that help
- Wear sunglasses in bright light, so you squint less.
- Do not skip sunscreen on cloudy days or near windows.
- Keep skin hydrated, especially in air-conditioned rooms and in winter.
- Sleep well, and try sleeping on your back if you notice creases on one side.
- Do not smoke.
- Be gentle: pat products in rather than rubbing, especially around the eyes.
What to expect
Dehydration lines often look softer within days of better hydration. Expression lines change more slowly, and no cream removes them. A steady routine with daily sunscreen helps keep skin looking smooth for longer. Results vary from person to person. If you want to discuss professional treatments, see a dermatologist.

Daily broad-spectrum sunscreen, a hydrating routine, gentle products and healthy habits such as not smoking and getting enough sleep.
Does hyaluronic acid help fine lines?
Hyaluronic acid helps the skin hold water, which can soften the look of dehydration lines. Follow it with a moisturizer.
Is niacinamide good for fine lines?
Niacinamide supports the skin barrier and can help skin look smoother with regular use. It works best alongside daily sunscreen.
When should I start an anti-aging routine?
Sunscreen every day is worth starting as early as possible. A hydrating serum and moisturizer can be added whenever you notice dryness or fine lines.

The short version
Fine lines in your 20s and 30s come mostly from sun exposure, dehydration and repeated expressions. Use sunscreen every morning, keep your skin hydrated with a toner, serum and moisturizer, be gentle, and keep the routine steady. Dehydration lines respond quickly; the rest is about protection over time.
