Best collagen: how to choose the right supplement?

From the age of 25, the body naturally produces less collagen—expect a loss of approximately 1% per year. Visible consequences: the skin loses firmness, the complexion dulls, and the first wrinkles appear.

With so many powders, capsules, gummies, and liquid formats available, it can be hard to know which to choose. At Lashilé Beauty, a French laboratory and pioneer of pharmacy-grade gummies, we share our analysis to help you select an effective formula tailored to your needs.

Why supplement with collagen?

As a key protein in the body (accounting for about 30% of our total protein mass), collagen supports the structure of the skin, as well as joints, hair, and bones. This reservoir depletes with age: by age 50, your initial capital has decreased by nearly 30%.

Scientific studies agree on one point: a daily intake of hydrolyzed collagen peptides can contribute to skin elasticity and hydration. To observe changes in facial contour and skin density, regular supplementation over 8 to 12 weeks is generally required.

The 4 essential selection criteria

1. Marine or bovine collagen?

•       Marine: concentrated in Type I, the collagen found in skin. Its low molecular weight makes it easier for the body to assimilate.

•       Bovine: a blend of Types I and III, better suited for joint comfort and muscle recovery.

To preserve facial firmness and a radiant complexion, the bioavailability of hydrolyzed marine collagen remains the gold standard—this is precisely what Lashilé Beauty formulas prioritize.

2. Types of collagen (I, II, III)

There are over 28 types of collagen, but three dominate in supplementation:

•       Type I: the pillar of skin, tendons, and bones—ideal for facial beauty.

•       Type II: targeted at cartilage and joint comfort.

•       Type III: acts as support for Type I in the blood vessels and skin.

3. The importance of hydrolysis

A raw collagen molecule is too large to be absorbed by the intestine. The enzymatic hydrolysis process breaks it down into small peptides (2,000 to 5,000 Daltons). These fragments cross the intestinal barrier and directly stimulate fibroblasts in the dermis—a concrete answer to the misconception that collagen is "destroyed in the stomach."

4. The right dosage

Clinical trials demonstrate the effectiveness of formulas dosed between 2,500 and 10,000 mg per day. Below this threshold, results remain barely visible on the skin.

Lashilé Collagen Shots deliver 5,000 mg of hydrolyzed marine collagen per vial, a clinical dose concentrated into a single daily intake.

Which format to integrate into your routine?

Consistency is the primary factor in the effectiveness of any treatment. It is best to choose a format you can stick with over time:

Format	Advantages	Constraints
Liquid shots	Full clinical dose (5,000 mg) in a single take, fast assimilation, no mixing or measuring required.	An all-in-one format concentrating the essentials in one vial—a slight investment, commensurate with a full clinical dose in one go.
Gummies	Practical, delicious, no water or preparation needed; 2 per day are enough to maintain the treatment over the long term.	Content designed for gentle intake, spread throughout the day rather than concentrated in a single serving.
Powders	Theoretically allow for high dosages (up to 10,000 mg), provided you dose correctly yourself each time.	Requires preparation for each dose (mixing, recalculating dosage, sometimes strong taste) and is inconvenient for travel (water/shaker needed).
Capsules	Easy to carry, neutral in taste—provided you accept multiple daily doses.	Require 4 to 8 doses spread throughout the day to reach an effective dosage, with a higher risk of missing doses and lower adherence over time.

 

Lashilé Collagen Shots leverage the liquid format: 5,000 mg of hydrolyzed marine peptides per vial, enriched with vitamin C, hyaluronic acid, and Q10, for an intake that takes only a few seconds.

Complementary active ingredients to look for

To multiply the results, check for the presence of these active ingredients in your supplement:

•       Vitamin C: essential for the body's natural collagen synthesis (claim recognized by EFSA/ANSES).

•       Hyaluronic acid: retains water in the heart of the tissues, to smooth out dehydration wrinkles.

•       Coenzyme Q10 & Vitamin E: protect skin cells against oxidative stress.

Misconceptions to discard

"Collagen is destroyed by gastric juices."

False. In hydrolyzed form (peptides), the molecule passes through the stomach filter without losing its assimilable properties.

"You can find 100% vegan collagen."

False. Collagen is exclusively of animal origin. Vegan alternatives are assemblies of amino acids and vitamin C, designed to stimulate your own production. Lashilé gummies are vegan when they do not contain animal collagen.

"Effects are visible in a few days."

False. Skin follows a renewal cycle of at least 28 days. Allow 4 weeks for hydration and complexion, and 8 to 12 weeks for a measurable action on wrinkles.
