Sunscreen... that is also a real treatment
For a long time, sunscreens had only one objective: to block the sun's rays.
True to our philosophy, we have designed a sunscreen that is also a real treatment.
Our mineral sunscreen doesn't just protect the skin: it supports, nourishes, and cares for it during sun exposure. Because well-nourished skin is also skin that better maintains its comfort, suppleness, and radiance.
Enriched with shea butter, raspberry seed oil, and carefully selected plant active ingredients, our formula transforms a simple act of protection into a true daily treatment.
What is an SPF?
The Sun Protection Factor (SPF) measures the protection offered against UVB rays, which are primarily responsible for sunburn.
Originally, SPF was conceived as a measure of time. In theory, an SPF 30 means that skin could get sunburned approximately 30 times slower than without protection, under laboratory conditions and when the product is applied in sufficient quantity.
In reality, this duration varies depending on many factors: the intensity of the sun, skin type, perspiration, swimming, the amount applied, and the frequency of reapplication. This is why sunscreen should never be used to intentionally prolong time spent in the sun.
SPF can also be expressed as the approximate percentage of UVB rays filtered:
- SPF 15: approximately 93%
- SPF 30: approximately 97%
- SPF 40: approximately 97.5%
- SPF 50: approximately 98%
- SPF 100: approximately 99%
- SPF 120: approximately 99.2%
It can be seen that the gains become progressively more modest as the SPF increases. Between an SPF 40 and an SPF 120, the difference represents approximately 1.7% additional UVB filtration.
However, protection does not only depend on the number on the bottle. The quality of the formula, generous application, regular reapplication, as well as other sun protection measures - such as wearing a hat, protective clothing, and seeking shade when the sun is at its strongest - play an essential role in protecting the skin.
Broad-spectrum protection
SPF only measures protection against UVB.
However, UVA rays penetrate deeper into the skin and contribute, in particular, to premature skin aging. This is why it is essential to choose broad-spectrum protection, capable of protecting against both UVA and UVB.
Why this level of protection?
Our formula offers high protection thanks to 25% non-nano zinc oxide, known for its broad-spectrum protection against UVA and UVB, in a surprisingly light and elegant texture for a mineral sunscreen.
This choice allows us to favor a formula composed of carefully selected ingredients, without compromising the elegance of the texture or the comfort of the skin.
Because beyond the number on the bottle, what really matters is the quality of the protection, the quality of the formula... and the pleasure of applying it generously, day after day.
Why mineral protection?
Zinc oxide acts primarily on the skin's surface by absorbing, diffusing, and reflecting some of the UV rays.
Photostable, very well tolerated by sensitive skin, and recognized for its broad-spectrum protection, it is a first-class choice for daily protection.
What it doesn't contain
Like all Maison Jacynthe skincare products, our sunscreen has been formulated with high standards.
You will not find:
- No chemical sun filters
- No nano-form zinc oxide
- No octocrylene
- No oxybenzone
- No silicones
- No petrochemical derivatives
- No synthetic fragrances
- No artificial colors
Only ingredients chosen for their real usefulness.
The ingredients that make the texture so pleasant
One of the biggest challenges of a mineral sunscreen is to offer an elegant texture.
We achieved this through a synergy of plant-based ingredients.
Shea butter nourishes and softens the skin.
Raspberry seed oil is rich in essential fatty acids and antioxidant compounds that help maintain skin comfort and suppleness.
Plant-based emollients replace silicones and provide a silky, non-greasy feel.
Natural silica leaves a velvety finish and helps reduce the white appearance often associated with mineral sunscreens.
Each ingredient has been chosen not only to protect the skin, but also to care for it.
Because sunscreen should never be limited to filtering the sun's rays. It should also preserve the comfort, suppleness, and natural radiance of the skin. This is the vision that guided the creation of our mineral sunscreen.
To complete your summer ritual and prolong your skin's radiance, incorporate the "Gel Coup d'éclat" and "Après-soleil" into your routine. Discover how to prepare your skin before sun exposure and care for it throughout the summer in our article: The summer skin you dream of starts before the beach.
