How does Laetigen work?
Laetigen delivers collagen into the skin. Collagen is the main structural protein of the dermis, and it naturally decreases with age, sun exposure and stress. A collagen booster aims to supplement the dermal framework and support the skin's own repair, which may improve firmness, hydration and the look of fine texture over time.
Who might Laetigen suit?
- People with thin, crepey skin or early fine lines
- Skin that feels dehydrated despite good skincare
- Those who want gradual skin-quality improvement without volume change
- Patients combining boosters with lifting or laser treatments
It is generally postponed during pregnancy or breastfeeding, with active skin infections, or for people with known allergies to collagen products. A doctor checks your history before treatment.
What happens during a session?
Numbing cream is applied, then Laetigen is injected into the dermis with fine needles or an injector device. Small raised bumps at injection points are common and usually settle within a day or two. Avoid makeup on the treated area for about 24 hours and skip saunas and strenuous exercise for a day.
How is Laetigen different from other boosters?
Each booster uses a different main ingredient. Laetigen is collagen-based; Rejuran Healer uses polynucleotides; CellREDM uses an extracellular matrix; and Re2O focuses on skin component support. Doctors choose based on your skin's needs, sometimes combining them. Our Laetigen vs Re2O comparison and are skin boosters worth it? give more context.
Is Laetigen right for me?
Re:berry's approach is diagnosis first. If dehydration or thinning is your main concern, a booster like Laetigen may form part of a plan, possibly with HydraFacial or lifting. See the Laetigen for dehydrated skin guide. Pricing depends on the amount used and the plan, and is confirmed in writing at consultation.
When will I notice a difference?
Boosters work gradually. Some people feel their skin is more hydrated within a couple of weeks, while changes in firmness and texture usually build over a series of sessions. Taking photos in consistent lighting helps track progress.

Related questions
Does Laetigen add volume like filler?
No. Laetigen is a skin booster designed to improve skin quality, such as firmness and hydration, rather than add visible volume. If you want to restore lost volume in folds or cheeks, filler may be discussed separately at consultation. The two can be combined in one plan.
How many Laetigen sessions are needed?
Boosters are usually planned as a series, often a few sessions several weeks apart, followed by maintenance. The exact number depends on your skin condition and goals. The doctor will suggest a schedule at consultation and adjust it based on your response.
What are the side effects of Laetigen?
Common effects include small bumps, redness, mild swelling and occasional bruising at injection points, usually settling within a few days. Less commonly, lumps, infection or allergic reactions may occur. Tell the doctor about any allergies before treatment. Most people return to normal activities the same day.
