Most of our products do not display expiry dates because they are stability-tested for over 30 months unopened. Safety and efficacy after opening are indicated via the period after opening symbol, in line with UK and EU cosmetic regulations.

Pregnancy can cause a number of different – but usually temporary – skin issues. If you have any specific concerns, you should consultant with a skin specialist.

However, we would recommend Pigment Correct and Collagen Restore. Also, please do ensure you are using sunscreen. Changes in hormones predispose pregnant women to developing new pigmentation.

Whilst our products are formulated with ingredients that, at their respective concentrations, are not deemed unsafe for topical use during pregnancy or breastfeeding, we recommend that pregnant and nursing mothers consult their medical practitioner before introducing any new skincare product into their routine.

Doctors generally advise against use of Vitamin A-based products (retinoids) during pregnancy (e.g. retinol, tretinoin etc).

Although there is little, if any, conclusive evidence that there is a risk to an unborn child from topical retinoids (as opposed to high risk from oral retinoids), some of the retinoid does get absorbed into the body.

As a precaution, we recommend against the use of Retin-ACE during pregnancy and breastfeeding mothers.

All of our other products can be used during pregnancy and breastfeeding.

Directions for use can be found on each product page. For further advice and guidance, please email us at hello@cellderma.com

Please note, as our formulations are regulated as cosmetic product, we cannot make any medical claims.

There will be directions on use on the product, although most serums and creams can be used twice daily if you wish.

Only Retin-ACE must be used at night only, along with ensuring you use a sunscreen every morning.

The basic rule of layering involves cleansing, serum/serums and then cream. In the morning, finish with a sunscreen and make-up  can be applied on top of your sunscreen.

Please do not rely on your make-up providing sun protection, as the protection is minimal and will not last long.

Less than you think. CellDerma products are highly-concentrated and you will notice that even the smallest drop goes far.

Guides such as the Finger-Tip Unit method are not necessary for our range so simply use what feels right. You want to cover all of your face and neck, and will know if you have used enough. That said, for pipette serums, 4-6 drops for the face and neck should suffice. For thicker serums from a pump bottle, 2 pumps is ideal but you may be able to economise with 1 pump. The same applies to the creams in the pump-jars.

Yes, as our range stands currently, all of our products qualify as vegan.

Absolutely not. When you purchase a CellDerma product, you can rest assured that neither the raw ingredients or final formulation have been tested on animals – and never will be.

Only Perfect Lips and PHA Renewal Scrub have small traces of fragrance.

All other products are fragrance-free. This minimises the risk of developing allergic dermatitis or skin hypersensitivities.

The vital role of amino acids in both skin and overall health, is often understated. Amino acids maintain skin resilience by supporting the immune system, hydrating the skin and protecting against free radical damage.

Although numerous, there are around 20 important amino acids for our health; split into essential and non-essential amino acids.

Essential amino acids are not produced by the body so must be obtained from external sources e.g. certain foods.

Non-essential amino acids are produced by the body.

However, for skin health, both types can be hugely beneficial when part of the right formula. CellDerma’s Youth Restore serum, has a high concentration of 13 essential and non-essential amino acids, chosen for their health-restoring potential.

Amino acids are the building blocks for the small proteins in our skin called ‘peptides’. Each amino acid will have a unique role of action.

The water transport system of the body consists of aquaporins or ‘channel proteins’. These are made up of amino acids including alanine and proline, both of which feature in Youth Restore.

Antioxidants are crucial to defence and damage control within the skin. Amino acids have antioxidant potential helping fight against free radicals. However, they go far beyond this, being capable of helping the skin replenish its own antioxidant levels.

GF5:
Acetyl glutamine: a pre-cursor for the synthesis of your natural super-hydrating hyaluronic acid in the skin. This amino acid is also a natural moisturising factor itself. It is also proven to reduce fine lines.

Amino acids are an integral part of the NMFs (Natural Moisturising Factors) in the skin, but also potentiate the benefits of other NMF components e.g. glycerides, hyaluronic acid and peptides, all of which are found in Youth Restore.
