How to apply body sunscreen?

A very common mistake: applying sunscreen once at the beginning of the day and assuming that's enough. The reality is quite different.

The correct sequence, step by step

For effective protection against UVA and UVB rays, application should be done before sun exposure, never after. Here's the ideal order:

  1. Skin cleansing (lotion, cleansing gel, or micellar water)
  2. Application of [ PSCHITT MAGIQUE ] — ourexfoliatorcan be used daily, unlike traditional scrubs recommended only 1 to 2 times a week
  3. Antioxidantserum
  4. Generous layer of SPF 50 body sunscreen

How much product to apply?

The dermatologists' rule: two milligrams per square centimeter of skin. In practice, a small dab per body area (arms, legs, back, stomach). Insufficient application halves or triples the actual protection factor.

Reapplication, the number one reflex

  • Every 2 hours during prolonged exposure
  • After each swim, even with waterproof sun spray
  • After intense sweating
  • After drying with a towel

An often-overlooked tip: apply body sunscreen 20 to 30 minutes before exposure. Chemical filters need time to penetrate to be fully active. Mineral filters (titanium dioxide) are active immediately upon application.

What are the effects of sunscreens?

Good body sun protection doesn't just block rays: it acts as a real daily skin treatment.

UV protection

Sunscreens filter UVA rays (responsible for skin aging and spots) and UVB rays (primarily responsible for sunburn and skin cancer risk). A broad-spectrum product covers both types of radiation.

Prevention of skin aging

Sun exposure without protection is the primary cause of premature skin aging: wrinkles, loss of firmness, dull complexion, pigment spots. From the age of 20, daily application of body sunscreen — even in winter — is the most effective anti-aging gesture there is.

To enhance this effect in the evening, [ MYSTERIEUX Mille et Un Jours ], with its anti-aging firming action, ideally complements sun care after exposure.

Hydration and comfort

The best body sunscreens incorporate moisturizing ingredients — hyaluronic acid, aloe vera, coconut extract — which maintain the skin's hydration level even in direct sunlight. The result: supple, comfortable skin protected from free radicals.

Prevention of spots

Skin spots appear or worsen under the effect of UV rays. A high sun protection factor (SPF 50) combined with adequate UVA protection helps limit their appearance and stabilize those already present.

What are the risks for pregnant women?

The question of the safety of sun protection products during pregnancy is legitimate. Some chemical filters raise concerns due to their potential for skin penetration.

Filters to watch out for

Certain molecules such as oxybenzone or octinoxate are classified as potential endocrine disruptors. To date, the identified risk remains limited in adults, but as a precautionary principle, pregnant women should avoid them.

To avoid during pregnancy:synthetic chemical UV filters (oxybenzone, homosalate, benzophenone). Prefer: formulas based on mineral filters (titanium dioxide, zinc oxide) with dermatological labels.

What to choose during pregnancy?

Mineral filters (titanium, zinc) present no significant risk and should be prioritized. Standard chemical filters, whose risk remains limited, should be avoided as a precaution. Oxybenzone and benzophenone, however, should be excluded due to a significant risk.

A dermatologist remains the best person to guide the choice of body sunscreen during pregnancy, especially in cases of sensitive skin or pre-existing skin conditions.

How to choose an effective sunscreen?

With the proliferation of products on the market — sun milk, oil, spray, stick, gel, fluid — the choice can seem complex. A few key criteria are enough to navigate it.

Sun Protection Factor (SPF)

SPF measures only protection against UVB. SPF 30 filters approximately 97% of UVB, SPF 50 filters 98%. The difference seems small, but it becomes noticeable during long or repeated exposures. For high sun protection, SPF 50 remains the reference.

Phototype, starting point

Phototype (from 1 to 6 according to skin tone and reactivity to the sun) determines the minimum recommended index.

Very fair skin (phototypes 1 and 2), which burns easily, requires SPF 50+. Fair to medium skin (phototype 3), which tans gradually, should opt for SPF 30 to 50. Medium to dark skin (phototypes 4 to 6), which tans quickly, can opt for a minimum SPF 15 to 30.

Texture adapted to your skin type

  • Dry skin:a sun milk or moisturizing sunscreen rich in hydrating ingredients (aloe vera, hyaluronic acid)
  • Oily or combination skin:an invisible fluid or gel with a light, non-comedogenic texture
  • Sensitive skin:a dermatological formula without fragrance, with mineral filters
  • Children and babies:a specific SPF 50+, hypoallergenic sun stick or spray

Broad-spectrum: non-negotiable

An effective sun product protects against both UVA and UVB. The encircled UVA logo on the packaging guarantees that UVA protection represents at least one third of the total UVB protection. Without this mention, protection against skin aging and spots remains incomplete.

Ingredients to value

  • Mineral filters (titanium dioxide, zinc oxide): well-tolerated, immediately active
  • Antioxidants (vitamin C, E, green tea extract): neutralize free radicals generated by exposure
  • Moisturizing agents (hyaluronic acid, aloe vera, glycerin): maintain skin comfort
  • Soothing agents (bisabolol, panthenol): ideal for reactive skin

Note: self-tanner and sunscreen do not do the same job. Self-tanning products do not contain any UV filters — body sunscreen remains essential, even when using them.
