Skincare After 30 — What to Change in Your Daily Routine?

Between the ages of 25 and 30, changes take place in the skin that aren't yet visible in the mirror but are already under way at the cellular level. Research published in the Journal of Investigative Dermatology (Shuster et al.) showed that type I collagen production drops by around 1–1.5% per year from the middle of the third decade of life onwards. At the same time, fibroblast activity declines and the natural synthesis of hyaluronic acid decreases. This isn't cause for panic — but it is a reason to adjust your skincare consciously.

What happens to skin after 30?

Visible signs don't appear overnight. The first signals are:

• Fine expression lines — especially around the eyes and on the forehead, more pronounced in the evening when you're tired.
• Slower regeneration — post-inflammatory hyperpigmentation after breakouts lingers longer than it did in your twenties.
• Loss of radiance — the skin's renewal cycle lengthens from about 28 to 35–40 days (data from the British Journal of Dermatology).
• First signs of dehydration — the lipid barrier becomes less effective, leading to increased transepidermal water loss (TEWL).

Retinol — when to start and at what concentration?

Retinol (vitamin A) is one of the best-researched anti-ageing ingredients. A meta-analysis of 12 randomised clinical trials published in Dermatologic Therapy (2019) confirms that retinol at a concentration of 0.1–0.5% significantly boosts collagen synthesis and reduces fine wrinkles after 12 weeks of regular use.

A protocol for introducing retinol after 30

1. Weeks 1–2: 0.1% concentration, applied once a week in the evening on dry skin.
2. Weeks 3–4: increase the frequency to twice a week.
3. Weeks 5–8: every other evening, watching how your skin reacts.
4. From month 3: move up to a 0.25–0.3% concentration if tolerance is good.

The key rule: always pair retinol with a moisturiser and mandatory SPF the following morning. Retinol increases the skin's photosensitivity — skipping sun protection cancels out the benefits and risks hyperpigmentation.

Vitamin C — the antioxidant of first choice

L-ascorbic acid at a concentration of 10–20% (ideally 15%, as in the classic studies by Pinnell et al., Dermatologic Surgery, 2001) neutralises free radicals generated by UV radiation and environmental pollutants. The effect isn't purely protective — vitamin C also stimulates collagen synthesis by stabilising the enzymes prolyl and lysyl hydroxylase.

Use a vitamin C serum in the morning, under SPF. Combining the two offers better protection than either ingredient alone. Look for formulas in packaging that protects against light and air — L-ascorbic acid oxidises quickly. Check out the available options in the PurScore search tool, filtering by active vitamin C content.

SPF — you don't negotiate with UV radiation

Sun protection isn't a matter of aesthetics. A study in the Annals of Internal Medicine (Hughes et al., 2013), carried out on 903 people over 4.5 years, showed that daily use of SPF 15+ slowed photoageing by 24% compared with the control group. After 30, SPF becomes the most important product in your routine — more important than any serum.

• SPF 30 minimum, ideally SPF 50 with UVA protection (look for the PA+++ marking or UVA in a circle).
• Apply around 1.25 ml to the face — roughly a quarter of a teaspoon.
• Reapply every 2 hours when exposed to the sun.

The eye area — a category of its own

The skin around the eyes is 3–5 times thinner than on the rest of the face and is practically devoid of sebaceous glands. After 30, the first "crow's feet" become more noticeable. An eye cream with caffeine (which reduces puffiness by constricting blood vessels) and peptides (such as Argireline — a hexapeptide that inhibits micro-contractions of the muscles) can be a valuable addition to your routine.

Don't expect miracles — no cream will erase deep wrinkles. But using one regularly from the age of 30 slows down the deepening of lines. Compare the formulas of eye creams in the PurScore cream ranking.

Supporting antioxidants — what beyond vitamin C?

Vitamin C is the foundation, but it isn't the only antioxidant worth your attention:

• Vitamin E (tocopherol) — works synergistically with vitamin C, regenerating it after it has neutralised free radicals.
• Niacinamide (vitamin B3) — at a concentration of 4–5% it strengthens the lipid barrier, reduces discolouration and regulates sebum production. Well tolerated, and it can be combined with retinol (contrary to the old myths).
• Resveratrol — a polyphenol with antioxidant activity, studied for its ability to protect skin cell DNA from UV damage (Free Radical Biology and Medicine, 2014).

What NOT to do after 30?

Overdoing your skincare can be worse than doing nothing at all. Avoid:

• Aggressive physical scrubs — abrading the skin with walnut shells or fruit stones has nothing to do with controlled exfoliation. Choose an AHA (glycolic acid 5–8%) twice a week.
• Daily use of multiple actives — retinol + acid + vitamin C on the same evening is a recipe for irritation, not better results.
• Ignoring your neck — every product you apply to your face should also reach your neck. Neck skin ages even faster.

Summary — the minimum plan after 30

You don't need a 12-step routine. Four elements are enough:

1. Cleansing — a gentle gel or milk, SLS-free.
2. Serum with 15% vitamin C — in the morning.
3. SPF 30–50 — every day, all year round.
4. Retinol 0.1–0.3% — in the evening, gradually increasing the frequency.

This is a foundation built on scientific evidence, not on trends. Add the rest consciously, after checking the formula in the PurScore ingredient database.
