For oily and combination skin — in most cases, yes. For dry skin, apply a moisturising cream before the SPF.

What is confirmed by testing
The key figures and the essentials about the product.
- 73.5Average SPF in vivo
- SPF 50+Official EU protection category
- 36.23UVA protection factor (UVA-PF)
- 5★UVA/UVB balance, Boots star rating
A fluid with a very high level of protection for those who choose sunscreen by test results rather than by the promises on the pack.
In in vivo testing the average SPF was 73.5 — well above the minimum of 60 required for the SPF 50+ category. Under EU labelling rules such a result is marked SPF 50+: it is the outcome of testing, not a marketing name.
A high SPF is not the whole story. SPF describes protection against UVB rays, which cause sunburn, while UVA rays, linked to pigmentation and photoaging, reach the skin every day. The fluid's UVA protection factor is 36.23, and the balance of its UVA/UVB protection received the maximum 5-star Boots rating. The formula combines five complementary UV filters: some target UVB, others UVA, and a broad-spectrum filter supports both.
The texture is a light milky fluid rather than a thick cream: it spreads easily and does not make the skin feel heavy, so SPF becomes a simple step of your daily routine instead of a chore. It also works as a moisturising base under make-up and gives the skin a natural, well-cared-for glow.

Ingredients and use
How to use and what to keep in mind
How to apply it, step by step; what to keep in mind is below.Steps: 7
When
Every morning as the last step of your skincare. Apply to clean skin of the face and neck 15–20 minutes before going out in the sun.
Where
The face first. If needed, also the neck, décolleté, hands, forearms, shins and legs.
How much
For the face and neck, use the two-finger rule. Too little product noticeably reduces protection.
How
Do not mix with serum, cream or foundation — apply in separate layers and let each one absorb.
Under make-up
Wait about 10 minutes after applying SPF for the protective layer to form, then apply foundation with light patting movements.
Reapply
Every 2–4 hours when you are outdoors in direct sun, and after swimming, heavy sweating, towel-drying, cleansing or rubbing the skin.
Reapply over make-up
Pat the fluid over the whole face with a clean sponge. Or blot excess sebum with a tissue and apply the fluid in small amounts with your fingertips, building up a new protective layer.
Precautions
- No sunscreen gives 100% protection — avoid staying in direct sun for too long.
- Also wear a hat, sunglasses and clothing that covers the skin.
- Using enough product and reapplying it regularly matter as much as the SPF number.
- Use SPF every day, all year round — not only in summer.
Cosmetics are care, not treatment. If your skin is irritated or you have a skin condition, consult a specialist.
