Understanding Spring and Summer Skin: The Science of Seasonal Change

The physiological background of everything that happens to your skin when the weather gets warmer. It explains how sebum, sweat, barrier function, and UV load change together in clinical language, but in a simple way for the patient.

  • When the season changes, the skin is not the same; barrier, sebum, and pigment behavior change.
  • In spring, the most critical task is to manage the transition; in summer, it is to reduce the load.
  • The same skincare routine does not work every season; the intensity of the content should be adjusted according to the season.

FREQUENTLY ASKED QUESTIONS

The main questions in this book

Concise answers distilled from the chapters for readers who want a quick overview of the book’s main topics.

Sun and protection

Question 1: "Is sunscreen really necessary on a cloudy day?" Yes. Although clouds partially filter UVB, 70-90% of UVA passes through. Protection is recommended for a UV index of 3 and above. Question 2: "I sit in an office, is SPF still necessary?" Yes, glass transmits UVA; a mineral formulation is also recommended for blue light effect. Question 3: "I have dark skin, do I need SPF?" Although dark skin types are more resistant to sunburn, there is a risk of DNA damage, melasma, and skin cancer. Lifelong protection is needed. Question 4: "Does SPF inhibit vitamin D synthesis?" In real life, sufficient vitamin D needs are safely met with oral supplementation. Therefore, reducing photoprotection would be a wrong trade-off.

Sunscreen and application

Question 5: "Is SPF 100 really twice as good as SPF 50?" No. SPF 50 filters 98% of UVB, SPF 100 filters 99%. The difference is very small; the main difference is the correct amount and repeated application. Question 6: "Is SPF 15 foundation under makeup sufficient?" No. The SPF of foundation remains very low in practice due to insufficient quantity. Apply a real SPF 50+ beforehand. Question 7: "How safe is spray SPF?" It may not be sufficient alone as quantity measurement is difficult. I recommend spraying it on your face and spreading it with your hand.

Skincare routine

Question 8: "Should I apply retinol every day?" Initially 2-3 days a week, then every other day as the skin tolerates it, then daily. The dose is adjusted as needed in summer. Question 9: "Should I store my vitamin C serum in the refrigerator?" It can be beneficial for some oxidation-sensitive formulations, but it is not mandatory for every formula. A dark glass bottle and a tightly closed cap are sufficient. Question 10: "Is a 10-step Korean routine really necessary?" No. For most skin types, 4-6 steps are sufficient and more sustainable. Question 11: "Should I wash my face every day?" Definitely in the evening. In the morning, only water or a gentle cleanser is sufficient depending on the dryness of the skin.

Medical aesthetics

Question 12: "Does it make sense to get Botox in the summer?" Yes, it is safe as long as you control UV exposure afterwards. Question 13: "Does filler melt in the summer?" Hyaluronic acid fillers do not melt with heat; however, swelling may be slightly more pronounced in the first few days in excessively hot environments. Question 14: "I am 25, is it too early to get Botox?" No, if there is mimic hyperactivity. The preventive dose is carefully planned. Question 15: "How many PRP sessions should there be?" Usually 3-4 sessions, 3-4 weeks apart. Afterwards, maintenance every 6 months. Question 16: "Does mesotherapy hurt?" Pain is minimal thanks to local anesthetic cream and thin needles.

Acne and spots

Question 17: "Is sunbathing good for acne?" No, although it may look good in the short term, increased melanin deepens spots and sabotages acne treatment. Question 18: "Homemade lemon/vinegar recommendation for my spots?" No, it can be irritating and phototoxic. Physician-controlled professional depigmentants are safe. Question 19: "Is toothpaste good for pimples?" No, it causes irritation. BPO or salicylic acid are more suitable for punctual spot treatment. Question 20: "Can melasma be treated during pregnancy?" Some topicals (azelaic acid, niacinamide) are safe, others are contraindicated. Physician control is essential.

Nutrition and lifestyle

Question 21: "Is chocolate bad for the skin?" Refined sugar and dairy products trigger acne in some people; dark chocolate is an antioxidant. It is individual. Question 22: "Does drinking water lighten spots?" Not directly; but adequate fluid intake is critical for overall skin health. Question 23: "Do collagen supplements work?" There are studies showing the contribution of hydrolyzed collagen peptides to skin elasticity; but not as much as topical and lifestyle. Question 24: "Does drinking coffee harm the skin?" Moderate consumption is fine, excessive caffeine can have indirect effects if it disrupts sleep quality.

Common mistakes

Question 25: "Will I apply the same routine every morning?" Yes, except for small seasonal adjustments. The discipline of the routine creates the effect. Question 26: "Should I keep changing products?" No. The skin shows the true effect of the product after 6-8 weeks. Frequent changes prevent results. Question 27: "More products mean better results?" No. A few correct products are always better than 15 wrong ones. Question 28: "Can I try my friend's routine?" To a limited extent. Everyone's skin, hormonal status, and needs are different. Question 29: "Is my skin getting used to it?" Tolerance develops to some actives; but the feeling of "losing its effect" is often wrong. Dose adjustment is done with a physician. Question 30: "Is genetics enough to look good?" No. Genetics is the starting
