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

Pure lactic acid – 92% (pH 3.5) – peeling agent

forprofessional use .

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 >

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.
