An alpha hydroxy acid.
Occurs naturally – Sour milk, yogurt, tomato
juice.
Largest molecules among AHAs – slower
penetration.
Less irritation. More hydrating
Lunch time procedure – no peeling
Good - dry & sensitive skin
Facilitate dissociation of epidermal cells.
desquamation of stratum corneum ,
regeneration.
hyaluronic acid in skin – water holding capacity –
moisturizing effect.
Epidermis - thinned, smoother, improved texture.
Reverse – photodamage, wrinkles, brown spots &
roughness of skin
pH or pKa - determinant factor for all acids.
L.A > pH 3.5 – Cosmetics as a moisturizer.
pH < 3.5 in higher concentration – peeling agent
15 – 30 % solution.
30% (pH 2.3) – used for sensitive, dry, oily, acne
prone, dehydrated skin.
40% ( pH 2.2) – used for dry, dehydrated, normal
skin, perfect for first time peel
users
50% (pH 2.0) – wrinkles , all skin types.
Pure lactic acid – 92% (pH 3.5) – peeling agent
forprofessional use .
Melasma
Acne
Hyperpigmentation
Sunburns
Dark circles
Photoaging/Photodamage
Actinic keratosis
Seborrheic keratosis
Active viral/bacterial infections
Inflammatory dermatoses
Unrealistic expectations
Photosensitising drugs
Resurfacing procedures - last 6 months
Exfoliating the surface of your skin
Deep cleansing pores
Fading dark circles
reducing hyperpigmentation
Evening out skin tone
Brightening & lightening skin
Reducing the appearance of wrinkles
Stimulating natural collagen production
L.A – Texture: sticky, yellowish solution
G.A - Watery, clear liquid.
L.A – expensive, fade hyperpigmentation better,
less harsh.
If you never got a peel done before – start with
L.A then try G.A
It is a component of jessener’s peel, Melaspeel
KH (see notes down).
Claze (Arginine HCl, Lactic Acid, Kojic Acid,
Urea, Arbutin, Citric Acid): Facial rejuvenation &
peri-orbital hyperpigmentation, lip lightening,
fine wrinkles.
Actipeel (Lactic acid 82%): Skin rejuvenation,
ageing, melasma and skin lightening.
Pyrulac (Pyruvic Acid 25%, Lactic Acid 25%):
photo damaged skin, body pigmentation &
superficial wrinkles.
Pre peel assesment
Explain the procedure to the patient
Priming
Consent form/photographic documentation
Application procedure – similar to other AHA
peels.
Peel application should be in the order:
Forehead > cheeks > chin > perioral >
periorbital.
We do this in this order because peel should
be applied from area of thick skin to thin
skin .
It is thickest In the area of forehead
Forehead should be neutralized last.
Large molecular wt – slower penetration – less
irritation
Used on sensitive skin & Rosacea.
L.A – is a humectant – used on dry skin.
Useful in improving the barrier function of the
skin
Naturally occuring in the skin – allergic reactions
rare.
Less downtime – normal skin 3 – 4 days
