Review

Results you may expect from using Dr. Barbara Sturm Sun Drops SPF 50:

Based on the ingredient analysis by CreamScan, these are the key benefits you can expect from using Dr. Barbara Sturm Sun Drops SPF 50:

  • A bit of moisturizing. It has a moisturizing rating of 1.7 out of 10.
  • Very high sun protection for prolonged sun exposure, such as spending the day at the beach, hiking, or outdoor sports.

How moisturizing is it?

Slightly moisturizing: Dr. Barbara Sturm Sun Drops SPF 50 has a moisturizing rating of 1.7 out of 10.

Is it more humectant or occlusive? Purely humectant. It has zero occlusivity (we didn't find any occlusive ingredients on the ingredient list) and a moderate humectancy of 3.4 out of 10, primarily due to Glycerin (est. ≈1.3%), Portulaca Oleracea Extract (est. ≈0.3%) and Pentylene Glycol (est. ≈0.3%).

Tip: Studies suggest that humectants alone do not moisturize the skin. We recommend applying a product with some occlusive ingredients after the use of this one.

Please refer to the Ratings section below for details of the moisturizing rating calculation.

Anti-wrinkle efficacy

According to CreamScan analysis, Dr. Barbara Sturm Sun Drops SPF 50 has a zero anti-wrinkle rating.

It contains Camellia Sinensis Leaf Extract, an ingredient marketed as effective in reducing wrinkles. However, the studies supporting the anti-wrinkle claims of Camellia Sinensis Leaf Extract provide insufficient evidence of its efficacy according to CreamScan Research Evaluation Standards. Therefore, this ingredient does not generate the anti-wrinkle rating.

Moisturizers, when used regularly, are proven to prevent wrinkle formation and even reduce existing wrinkles. Therefore, this product, like any other moisturizer, could deliver some anti-wrinkle effects through its moisturizing action.

Please refer to the Ratings section below for details of the anti-wrinkle rating calculation.

Sun protection

Dr. Barbara Sturm Sun Drops SPF 50 has an SPF of 50 and provides very high sun protection. This level of protection is ideal for activities involving intense or prolonged sun exposure, such as spending the day at the beach, hiking, or outdoor sports. It is particularly recommended for individuals with fair skin, those at high risk of skin cancer, or in environments with intense sun exposure. Remember to apply sunscreen generously and reapply every two hours or after swimming or sweating to maintain effectiveness.

Ingredients explained

Water
Est. %65
Function
Origin
The most used ingredient in skincare. Its concentration defines the product texture: rich creams may have about 50% of water while a light jelly about 90%. Water doesn’t moisturize the skin by itself and is used in skincare as a solvent for other ingredients.
Homosalate
Est. %10
Function
Origin
A synthetic chemical UV filter that protects against harmful UVB radiation.
Octinoxate
Est. %7.5
Function
Origin
A chemical sunscreen also known as ethylhexyl methoxycinnamate. It protects against UVB, which causes the skin to burn and tan and can lead to certain types of skin cancers. For broad-spectrum protection claims, octinoxate should be paired with a UVA sunscreen.
Octisalate
Est. %5
Function
Origin
A UVB sunscreen also known as ethylhexyl salicylate. It is normally paired with UVA sunscreens to provide broad-spectrum protection. Octisalate also protects other ingredients, like colorants and antioxidants, from deterioration due to exposure to UV light.
Avobenzone
Est. %3
Function
Origin
A popular sunscreen that protects against UVA rays, which cause premature aging and skin cancer. Avobenzone degrades after about 30 minutes of sun exposure and becomes ineffective. It is therefore often paired with UV-filter stabilizers such as octocrylene.
Butyloctyl Salicylate
Est. %1.5
Function
Origin
A synthetic emollient and solvent. It is primarily used as a carrier oil to disperse minerals in, including pigments and sunscreen minerals. It can also absorb UV light, thus boosting the SPF of sunscreen products.
Glycerin
Est. %1.3
Function
Origin

The most popular moisturizing ingredient in the world. It is a powerful humectant – cheap yet very effective.

Styrene/Acrylates Copolymer
Est. %1
Function
Origin

Potassium Cetyl Phosphate
Est. %0.3
Function
Origin
A powerful emulsifier that can even mix particularly problematic water and oil blends. It is also a surfactant perfect for cleansing products that effectively rinse off oil and dirt particles from the surface of the skin.
Cyclopentasiloxane
Est. %0.3
Function
Origin
A lightweight, fast-spreading emollient that leaves a very soft and silky after-feel on the skin. Supplied as a clear and colorless liquid, cyclopentasiloxane is often used as a solvent to dissolve other silicones in.
Glyceryl Stearate
Est. %0.3
Function
Origin
An emollient and emulsifier typically derived from vegetable sources through a chemical reaction with glycerin. It provides stability, texture, and consistency to formulations. Its main function is to allow oil and water to mix.
PEG-100 Stearate
Est. %0.3
Function
Origin
This surfactant is more specifically classified as an emulsifier that produces oil-in-water emulsions. PEG-100 stearate can also be used as a cleansing agent.
Aluminum Starch Octenylsuccinate
Est. %0.3
Function
Origin
An absorbent that takes in oils from the skin to reduce the oily sheen. It can also absorb oils from the skincare product itself, resulting in a softer, less greasy product, normally with better spreadability and less tack.
Portulaca Oleracea Extract
Est. %0.3
Function
Origin
Derived from green or common purslane, this moisturizing extract is particularly rich in alpha-linolenic acid, an omega-3 fatty acid, and contains antioxidant glutathione and vitamin E. As a herbal medicine, it is believed to treat headaches and inflammation.
Phenoxyethanol
Est. %0.3
Function
Origin
The most frequently used preservative in skincare. It is a clear, oil-like liquid synthetic substance that protects products from harmful bacteria and yeast, whilst still leaving skin microflora unharmed. It is confirmed by research to be harmless.
Tocopheryl Acetate
Est. %0.3
Function
Origin
An antioxidant derivative of tocopherol (vitamin E). It helps to protect cells from free radicals and UV damage through the conversion to active vitamin E in the skin. It is more stable than tocopherol.
Polyacrylate-13
Est. %0.3
Function
Origin
A synthetic, film-forming ingredient that creates a network around other ingredients in the formula and protects them from being easily washed away.
Pentylene Glycol
Est. %0.3
Function
Origin
A naturally or synthetically derived preservative that exhibits effective antifungal and antibacterial traits. It also acts as a booster for more traditional preservatives. Pentylene glycol can also serve as a moisturizing humectant and solvent.
Xanthan Gum
Est. %0.3
Function
Origin
A natural multi-functional ingredient that originates from fermented sugars. Xanthan gum acts as a viscosity-building agent to thicken skincare products. It is also an excellent stabilizer and works well to hold other ingredients together.
Benzoic Acid
Est. %0.3
Function
Origin
A preservative effective against fungi, yeast, and some bacteria. It is commonly paired with phenoxyethanol to create a broad spectrum preservation system. Benzoic acid can also serve as a pH adjuster, fragrance, and bulking agent.
Ethylhexylglycerin
Est. %0.3
Function
Origin
A preservative booster derived from glycerin. It is commonly paired with other preservatives to improve their efficacy. Ethylhexylglycerin is also a humectant due to its chemical base of glycerin.
Glycereth-2 Cocoate
Est. %0.3
Function
Origin
Description is coming soon
Sodium Hyaluronate
Est. %0.3
Function
Origin
A sodium salt of famous hyaluronic acid. A potent humectant that hydrates the skin, supports collagen function, and fills out small wrinkles. Sodium hyaluronate also offers soothing and antioxidant properties.
Polyisobutene
Est. %0.3
Function
Origin
A highly viscous liquid that is used in lip gloss formulations to prolong wear time and add shimmer. Polyisobutene dramatically increases the thickness of skincare products it is added to.
Polysorbate 20
Est. %0.3
Function
Origin
A viscous, amber-colored liquid that functions as a solubilizer to disperse small amounts of oil into a large water phase. Polysorbate 20 is frequently used to solubilize fragrance oils into water-based emulsions.
Panthenol
Est. %0.3
Function
Origin
A popular soothing and moisturizing derivative of vitamin B5. Panthenol is particularly beneficial for dry, flaking, burned, or damaged skin. It is used to alleviate the symptoms of a rash, dermatitis, eczema, chapped lips, and sunburn.
Arginine
Est. %0.3
Function
Origin
A humectant amino acid used to attract water to the skin’s surface. It is a part of the skin's Natural Moisturizing Factor, a mixture of various compounds that keeps the skin’s surface well hydrated. Arginine can also be used as a pH adjuster.
Sodium Carboxymethyl Beta-Glucan
