Changing Skincare in Summer: How to Adapt Your HBSKN – Hebi Skin Routine to the Seasons
Contents
Your winter skincare works well — your skin is hydrated, not dry or irritated. Then summer arrives and something breaks: your skin is too shiny, your pores seem more dilated, the cream you've been using for months suddenly feels heavy.
It's not that the cream stopped working. It's the environment that has changed — and your skin with it.
Understanding when and how to change your skincare routine in summer (or winter) doesn't mean overhauling every product. In most cases, it means adjusting two precise variables: the level of hydration and the intensity of sun protection. This article explains exactly how to do it with the HBSKN – Hebi Skin routine.
What truly changes in your skin between winter and summer
Skin is a dynamic organ that actively responds to environmental conditions. The two main factors that change between seasons — and have the biggest impact on skincare — are relative air humidity and UV radiation intensity.
In winter, external humidity is low, and indoor heating and enclosed environments further reduce it. Skin loses water through trans-epidermal water loss (TEWL) at a faster rate. The result is skin that feels tight, looks dull, and can react with redness or flakes in more sensitive areas. Sebum production slightly decreases, but this doesn't improve the situation: without sufficient lipids, the skin barrier weakens, and the skin becomes more reactive to external agents — wind, temperature fluctuations, pollution.
In summer, external humidity increases, but so do perspiration, sebum production, and the accumulation of impurities in the pores. UVB rays — responsible for sunburn — reach their maximum intensity. UVA rays — which penetrate deeply and accelerate photoaging — remain constant throughout the year, but combined with summer exposure, they cause significantly higher cumulative damage. According to the Skin Cancer Foundation, in the summer months, the risk of UV damage from one hour of exposure is up to 4 times higher than in winter, at the same latitude.
The most common skincare mistakes during seasonal transitions
Before we look at what to do, it's worth identifying what not to do — because the two most frequent mistakes go in opposite directions.
Mistake 1 — Using the same amount of moisturizer all year round. In winter, skin needs more deep hydration to compensate for water loss due to evaporation. In summer, the same amount can be excessive, create a film on the surface, and make the skin abnormally shiny. There's no need to change products: just adjust the dose.
Mistake 2 — Lightening or removing sun protection in winter. UVA rays don't go on vacation. They penetrate through clouds and windows, are present every day of the year, and are the main cause of cumulative photoaging. Reducing or suspending sun protection in the colder months is one of the mistakes with the most lasting impact on long-term skin quality.
How to adapt the HBSKN – Hebi Skin routine in summer
The Hebi 5-step routine doesn't need to be revolutionized with the change of season — it needs to be calibrated based on three variables: dosage, frequency, and order of priority.
CLEANSE — unchanged, but more important in summer
CLEANSE maintains its function all year round: balanced cleansing morning and evening without aggressing the hydrolipidic film. In summer, with excess sweat and impurities, evening cleansing becomes even more critical if possible. Never skip it, even after a seemingly not-intense day.
HYDRATE — same product, reduced dosage in summer
HYDRATE works well in both seasons thanks to Pentavitin®, which doesn't add surface weight but binds directly to corneocytes. In summer, if your skin is already sufficiently hydrated by environmental humidity, you can reduce the dosage from 3 drops to 2. If you have combination or oily skin in the T-zone, apply HYDRATE only to the drier areas — cheekbones, periorbital area — leaving the T-zone with just cleanser and sun protection.
In winter, the situation reverses: the skin needs more prolonged water support, and Pentavitin® with its 72-hour covalent bond becomes even more relevant. If you experienced a particularly dry winter, also read our in-depth article on how to manage skin in winter in cold and humid cities.
PROTECT+ — SPF 50+ all year round, but with different focuses
PROTECT+ is the element of the routine that changes least between seasons — in the sense that it should never be removed. What changes is the awareness of its use.
In winter, it's used as a daily antioxidant and UVA shield, often underestimating actual exposure (car commutes, window light, cloudy skies).
In summer, it becomes the absolute priority: SPF 50+ applied in the correct amount (about half a teaspoon for the face), every morning, with reapplication every 2 hours in case of prolonged direct exposure. The new generation filters in PROTECT+ — without oxybenzone or octinoxate — ensure effective UVA/UVB protection without white residue or stickiness, even in summer temperatures.

PURIFY — reduced frequency in summer
The 7% glycolic acid in PURIFY increases skin photosensitivity. This doesn't mean it should be suspended in summer — it means it should be used judiciously.
In winter: 3-4 evenings a week as per the standard routine. In summer: reduce to 2 evenings a week, preferably the evening before days with less sun exposure. Never apply PURIFY in the morning. Make sure PROTECT+ is applied every morning without exception.
ANTI-AGE+ — the night rhythm does not change
ANTI-AGE+ works at night and has no problematic interactions with the summer season. Q10 and Retinyl Palmitate act during the nocturnal tissue regeneration phase, regardless of external conditions. Maintain the standard rhythm — alternate evenings with PURIFY — all year round.
Seasonal comparison in summary
Winter — priorities change as follows: Skin loses more water through evaporation: slightly increase the dosage of HYDRATE and be consistent with PROTECT+ even on cloudy days. PURIFY at standard frequency (3-4 evenings). ANTI-AGE+ unchanged. Main risk: reactive skin due to barrier weakened by cold.
Summer — priorities change as follows: Reduce the dosage of HYDRATE if environmental humidity is high. Maintain PROTECT+ with SPF 50+ every morning without exception and reapply if you are outdoors. Reduce PURIFY to 2 evenings a week. ANTI-AGE+ unchanged. Main risk: cumulative UV damage and clogged pores from sebum and sweat.
Frequently Asked Questions
No. The HBSKN – Hebi Skin routine is formulated to work all year round. The variables to modify are dosage and frequency, not the products. It's one of the main advantages of a routine built with balanced functional ingredients.
It is not advisable. Even in summer, skin needs hydration — sebum doesn't replace water in tissues. Dehydrated skin produces more sebum as a compensatory response, worsening the situation. Reduce the dosage of HYDRATE, but don't eliminate it.
Yes. UVA rays penetrate through windowpanes. If you work near a window, you're exposed to UVA for hours every day — in any season. Daily protection is relevant even when working from home.
Observe the feeling of tightness after cleansing (before applying other products): if it persists for more than 30 seconds, your skin is under-hydrated. If your skin already appears shiny before applying HYDRATE, you can reduce the dosage. These signs change with the seasons and weeks — it's not necessary to find the perfect formula once and for all.
Follow the logic of the local climate rather than the calendar. If autumn is still warm and sunny, maintain the summer protocol. If spring is cold and windy, maintain the winter one. Skin responds to the environment, not the date on the calendar.
Conclusion
Changing your skincare in summer doesn't mean buying new products — it means understanding what your skin needs when environmental conditions change, and responding with small, precise adjustments.
With the HBSKN – Hebi Skin routine, you already have all the necessary tools for both seasons. What changes is how you use them: HYDRATE dosage, PURIFY frequency, attention to PROTECT+ application. Three variables. No revolution.
