The difference between reaching summer and reaching summer prepared

Reaching summer with prepared skin doesn't mean arriving with an immediate tan — it means arriving with skin that tolerates the sun better, dehydrates less, stains less, and looks healthier and more radiant throughout the season.

Aesthetic medicine offers specific tools to prepare the skin before summer. These are not cosmetic tricks: they are treatments that act on the structure of the skin tissue, reinforce the barrier function, increase dermal hydration, and prepare the skin's defense mechanisms against sun damage.

At Santé Clínica Estética, pre-summer protocols are among the most requested starting in March. We explain how we design them and what objectives we pursue.

The four pillars of medical skin preparation for summer

Pillar 1: Cell renewal before sun exposure

The superficial layer of the skin accumulates dead cells during the winter months (less renewal, drier environment). This accumulation leads to irregular texture, lack of radiance, and poor absorption of active products applied afterward.

The first step before summer is to renew this superficial layer. The most effective medical methods are:

Gentle-to-medium chemical peel: controlled removal of the superficial layers of the epidermis using acids (glycolic, mandelic, low-concentration TCA). The result: cell renewal, finer pores, smoother texture, the first step towards depigmentation.

Important: medium-to-strong peels are not performed in summer (risk of hyperpigmentation with sun exposure). The ideal time is March-April, which allows enough time for recovery before intense sun exposure.

Deep facial cleansing + retexturization: for skin less suitable for chemical peels (sensitive skin, mild rosacea), the alternative is a deep medical cleansing with extraction and enzymatic exfoliation.

Pillar 2: Dermal hydration

Well-hydrated skin in the dermis resists summer dehydration much better. Dermal hydration is achieved with:

Skin booster: the benchmark treatment for intradermal hydration. High water-affinity hyaluronic acid injected directly into the dermis. 2-3 sessions between March and May ensure that the dermis enters summer with its water reserves full. Effects last 6-9 months.

Hydrating mesotherapy: cocktails of low molecular weight hyaluronic acid, vitamins, and amino acids administered into the superficial dermis. It complements the skin booster or works independently for skin with a lower degree of dehydration.

Pillar 3: Antioxidant protection

The sun generates free radicals that damage cellular DNA, degrade collagen and elastin, and alter melanocytes. Antioxidant preparation before summer reduces this damage:

Vitamin C 10-20% (serum): the most studied antioxidant in dermatology. Neutralizes free radicals, inhibits tyrosinase (the enzyme responsible for spots), and stimulates collagen synthesis. Start 6-8 weeks before summer to maximize tissue concentration.

Oral antioxidants: vitamins C and E, astaxanthin, resveratrol, beta-carotenes. They do not replace photoprotection but enhance the tissue's defense against oxidative sun damage.

Darker phototypes (III-VI): need special attention with preventive depigmenting agents (niacinamide, kojic acid) to minimize melanocytic reactivity to the sun.

Pillar 4: Photoprotection — the foundation of everything

No pre-summer protocol makes sense without proper photoprotection. SPF50+ UVA/UVB is not optional in summer: it is the most cost-effective measure in all of aesthetic medicine.

The most common mistakes:

  • Using insufficient SPF (less than 30 in summer: insufficient)
  • Not reapplying (sunscreen lasts ~2 hours of direct exposure)
  • Not protecting forgotten areas (neck, décolletage, hands, lips)
  • Thinking that if there is no direct sun, it is not necessary (UVA rays penetrate on cloudy days)

At Santé, we explain in detail to each patient how to apply and reapply sunscreen according to their activity.

When to start: the pre-summer calendar

| Month | Recommended treatments |

|-----|---------------------------|

| March | Chemical peel (medium), vitamin C serum, nighttime retinol |

| April | Skin booster (1st session), mesotherapy |

| May | Skin booster (2nd session), oral antioxidants |

| June | Skin booster (optional 3rd session), transition to daily SPF50+ |

| July-August | Mild hydrating maintenance, strict photoprotection |

This calendar is indicative. The doctor adapts it according to skin type, history of sun damage, and previously performed treatments.

Treatments to avoid in spring-summer

Some treatments should be avoided or limited during months of high sun exposure:

  • Medium and deep peels (TCA > 20%, phenol): only in autumn-winter
  • IPL laser and ablative laser: require skin without active tan; only in autumn-winter
  • High-concentration retinol: phototoxicity; reduce dose in summer or apply only at night
  • Vitamin C > 15%: well tolerated at night; in summer morning only if SPF50+ is applied on top

Santé's personalized protocol

There is no standard "seasonal" protocol. Skin preparation for summer at Santé begins with a medical assessment where we evaluate:

  • Skin type and phototype (Fitzpatrick I-VI)
  • History of spots and previous sun response
  • Current skin condition: dehydration, texture, sensitivity
  • Previous treatments and current cosmetics
  • Summer lifestyle: type and duration of sun exposure, water activities

With this information, we design a plan that combines the most suitable treatments so that you arrive at summer with the best possible skin.

Frequently asked questions

Is it too late if I start in May?

No. Skin booster and mesotherapy can be done in May-June without a problem. Peeling needs a bit more time (ideally 4-6 weeks before intense exposure).

Does skin preparation help prevent skin cancer?

Medical treatments improve skin quality and strengthen skin defenses, but they do not prevent skin cancer. Skin cancer prevention fundamentally depends on photoprotection, mole control, and regular dermatological check-ups.

Does it work for all skin types?

Yes, although the protocol varies greatly depending on the phototype and history. Darker skin types (phototypes IV-VI) have a higher risk of post-treatment hyperpigmentation and require more conservative protocols.

How much does the pre-summer protocol cost?

It depends on the treatments included. During the medical consultation, we will present the options and their prices in detail.
